Texto completo da fonteResumo:
Macrozoobenthos is one of the organisms that can be used as biological indicators because it tends to live in an area and has sensitivity to environmental changes. The Hurun River had many community activities. Based on this, it was necessary to analyze the diversity of macrozoobenthos which will be compared with the physical and chemical parameters of water in order to find out the indicators that affect the abundance of macrozoobenthos in the river. The purpose of this research was to determine the macrozoobenthic community structure which found in the Hurun River based on diversity, uniformity and dominance indices, to build multiple linear regression models, and to determine the bioindicators of pollution in the Hurun River. The factors that influence the abundance of macrozoobenthos are temperature, depth, brightness, DO, TOM, and salinity. The types of macrozoobenthos obtained were 87 species with the highest abundance of macrozoobenthic animals of 70,666.56 ind/m3 while the lowest abundance of macrozoobenthic animals was 13,000.96 ind/m3. Based on data analysis, the macrozoobenthic diversity index was included in the medium category, the level of macrozoobenthic uniformity was included in the high, medium, and low categories, and the dominance level which was included in the medium and low categories. Multiple regression models with a confidence level of 5% get R2 results of 0.86. The level of pollution that occured in the Hurun River based on bioindicators with the ABC curve shows moderately polluted.

This study aims to determine the macrozoobenthic community, the effect of rock mining on the macrozoobenthic community, and the water quality of the Logawa River. The research method used is purposive random sampling technique at 5 stations with 3 replications. The results showed that species richness, individual abundance and diversity were low at several stations because not all macrozoobenthos had a tolerance value for living in waters where sediment conditions had been affected by rock mining. Meanwhile, the dominance index value of the high category at station 3 was due to the effects of rock mining which caused macrozoobenthos who were intolerant of rock mining to move, so that only macrozoobenthos that were resistant to such conditions survived and dominated the area. Water quality for macrozoobenthos is still quite good based on the measurement results.

Abstract Distribution patterns and species composition of macrozoobenthos were studied in the Dutch coastal zone in front of the Port of Rotterdam. Relationships between macrozoobenthic assemblages and environmental variables were determined using non-metric dimensional scaling (nMDS) based on 470 boxcore, bottom sledge, and sediment samples collected in spring 2006 and 2008 in a 2500-km2 research area. We investigated two types of benthic assemblages, infaunal assemblages sampled with a boxcorer and epifaunal assemblages sampled with a bottom sledge. Five main in- and epifaunal assemblages were distinguished using clustering techniques and nMDS ordinations. Macrozoobenthic species composition correlated with combinations of measured sediment variables and modelled hydrodynamic variables. Macrozoobenthic species richness and biomass were highest at 20 m deep areas with a grain size of 200 µm, elevated mud and sediment organic matter, and low mean bed shear stress. Considerable interannual differences in macrozoobenthic assemblage distribution were observed which resulted from more Echinoids, Phoronids, and jackknife clams. A distinct, highly productive and species-rich macrozoobenthic white furrow shell Abra alba assemblage coincided in a 8-m deepened shipping lane and near a disposal site for dredged fine sediment. This may be an indication that the benthic system can be changed by these human activities. Modelled bed shear stress is an important variable in addition to sediment variables in explaining distribution patterns in macrozoobenthos.

The macrozoobenthic structure inhabiting marine ecosystem may be used as a bioindicator of changes in aquatic environmental disturbance. This study is aimed to assess environmental disturbance by application of biomonitoring using macrozoobenthic assemblages at coastal area of Menjangan Besar Island, Kepulauan Karimunjawa, Indonesia. The macrozoobenthic assemblages were assessed at two sampling locations, i.e. floating net cage of monoculture and reference areas. Each sampling location consisted of three stations with three replicates for each station. The samples were taken in two sampling times, i.e. August and November 2018. Data of abiotic parameters included the composition of organic matter content, sediment substrates, DO, pH, salinity, temperature, and water current. Sediments were sampled using Ekman grab from 15 m deep. The relationship between biotics (macrozoobenthos) and abiotics (physical-chemical factors) was assessed using a non-parametric multivariate procedure (BIO-ENV; Primer 6.1.5). Macrobenthic assemblages consisted of 89 species with the total abundance of 50,071 individuals/m2, consisting of 52 families and 4 classes of macrozoobenthos. The values of indices were ranging from 2,54-3,40 for diversity index (H'), 0,99 for Pielou’s evenness index (e’), and 0,09-0,17 for dominance index (C). The most common classes were a member of Gastropods and bivalves. Diversity and evennes indices exhibited differed by location (monoculture vs reference) and time sampling. Fluctuation of macrobenthic structure was considered as a results of environmental changes spatially and temporally, especially sediment composition and food availability as the form of organic matter. Nitrogen and silt were the most chemical and physical factors influencing the structure of macrozoobenthos (r = 0,632; BIO-ENV).

Macrozoobentos are organisms that live at the base of the water (Epifauna) or in the substrate (Infauna) with a size greater than 1 mm. Macrozoobenthos play an important role in the process of decomposition of organic matter in the sediment in the mangrove ecosystem. This research was conducted in August 2018 in the mangrove areas of Serangan Island, Bali. This research has purpose to know the structure of the Macrozoobenthos community in the mangrove ecosystem. It using a purposive sampling method, which consists of 2 stations, located in the north (adjacent TPA Suwung) as station 1 and on the south (directly facing the sea) as station 2. Each station consists of 5 substations with the distance between the substations adjusted to the condition of the existing mangrove community and each substation has 3 plots with a distance between the plot 10 m. The transect is drawn towards the sea for 50 m. The results obtained at station 2 had higher abundance of macrozoobenthos than Station 1, his shows the condition of the substrate at station 2 it supportive for the survival of macrozoobenthos organisms. The difference in the substrate in each station is thought to be one of the factors that influence the difference in macrozoobenthos density. At stations 1 and 2 have medium diversity, high Eveness and low dominance. This shows that the macrozoobenthos community in the mangrove ecosystem in the north and south of Serangan Island is in a stable condition but if the environment experiences a change, the change will affect the structure of the macrozoobenthos community in the ecosystem environment so that the value of species diversity is at a medium level.

"The management of marine areas are guided by environmental policies, such as European Union’s Marine Strategy Framework Directive (MSFD), Water Framework Directive (WFD) and Habitats Directive, all requiring periodic assessment and reporting. In 2020, the macrozoobenthos was monitored on the entire Black Sea Romanian shelf at depths ranging between 10 and 100 m. Out of the 43 sampling points of the marine monitoring network, 56 samples were collected in 22 selected stations distributed among broad sedimentary habitat types in Romanian waters in three marine reporting units (variable salinity waters, coastal waters and marine waters). Six types of sedimentary habitats were identified in the above-mentioned marine reporting units according to Marine Strategy Framework Directive (MSFD). Marine Strategy Framework Directive (MSFD) clearly specifies that assessment must take into consideration benthic broad habitat types, including their associated biological communities. To assess the ecological status according to the MSFD of macrozoobenthos from the Romanian shore, M-AMBI*(n) index was used. Following the assessment, the ecological status of the macrozoobenthic communities was determined as good in all three marine reporting units. The data collected in 2020 will contribute to the six-year assessment of the benthic broad habitats and establishment of thresholds for different sub-types.

Texto completo da fonteResumo:
Numerous studies have focused on the soft bottom macrozoobenthos from Mediterranean transitional environments, pointing out a correlation between the variation in environmental parameters and changes occurring in benthic communities. Less attention has been paid to the study of hard bottom organisms settling on both natural and artificial substrates usually present within the basins and often constituting peculiar communities. The ecological role of such communities is remarkable, since they often reach high values of species richness and include bioconstructor organisms able to build true reefs. These reefs can strongly impact the environment, improving biodiversity through the increase of spatial heterogeneity. The present work aims to supplement new faunistic data on five lagoon systems of the south-eastern Italian coast, integrating the still fragmentary knowledge of their macrozoobenthos through the study of hard substrate communities. Sampling was performed on hard substrates colonized by complex benthic communities. The assemblages recorded were then compared in the light of the study sites’ main ecological traits. Our data highlighted the occurrence of a rich benthic macrofauna, with 100 taxa found. This markedly increases the value of species richness reported in the literature for the macrozoobenthos of the study sites. In particular, the species list provided for the Ugento Basins was the first ever compiled for this site. In spite of their geographical proximity, the investigated sites, according to their diverse environmental conditions, showed substantial differences as regards their respective macrozoobenthic communities.

The aim of this study is to analyze and relate the spatial-temporal variability of macrozoobenthic assemblages to bottom characteristics and salinity fluctuations, in an estuarine shallow water region of Patos Lagoon. Monthly samples, between September 2002 and August 2003, were taken on six sampling stations (distant 90 m). Three biological samples with a 10 cm diameter corer, one sample for sediment analysis, fortnightly bottom topography measurements, and daily data of temperature and salinity were taken from each station. Two biotic and environmental conditions were identified: the first corresponding to spring and summer months, with low macrozoobenthos densities, low values of salinity, small variations in bottom topographic level and weak hydrodynamic activity. A second situation occurred in the months of fall and winter, which showed increased salinity, hydrodynamics and macrobenthos organisms. These results which contrast with previous studies carried out in the area, were attributed to failure in macrozoobenthos recruitments during summer period, especially of the bivalve Erodona mactroides Bosc, 1802 and the tanaid Kalliapseuses schubartii Mañe-Garzón, 1949. This results showed that recruitments of dominant species were influenced by salinity and hydrodynamic conditions.

Texto completo da fonteResumo:
To assess the effect of the zebra mussel (Dreissena polymorpha) invasion on benthic animal communities, we monitored the macrozoobenthos at eight sites in the freshwater tidal Hudson River in 1990-1995. Zebra mussels were absent or scarce in the Hudson River before September 1992, but abundant (mean 17 000/m2) on hard substrata in 1993-1995 and responsible for large declines in phytoplankton biomass. All of our monitoring stations had soft sediments, and so had low local densities of zebra mussels (mean 78/m2). Nevertheless, we observed marked changes in the macrozoobenthos at these stations. Sphaeriid clams declined by 67% between 1990-1992 and 1993-1995, but no other group of macrobenthos showed a simple change in density between 1990-1992 and 1993-1995 across all eight monitoring sites. Instead, most taxa showed a strong interaction between zebra mussel impacts and water depth. At deep-water sites, macrozoobenthic density declined by 33% between 1990-1992 and 1993-1995, while at shallow-water sites, density rose by 25%. We suggest that these changes were probably caused by reduced sedimentation of edible particles at deep-water sites combined with increased biomass of macrophytes and attached algae at shallow-water sites.

Abstract137Cs activity concentrations were determined in macrophytes and macrozoobenthic organisms from the southern Baltic Sea. Cesium isotope content was analysed in macroalgae species (green, red and brown algae representatives) and in some species of vascular plants. The analyzed macroinvertebrate organisms included bivalves and a crustacean.Concentration factors (CF) were calculated using the determined 137Cs concentration in the flora and fauna organisms against that in seawater, and the bioaccumulative properties were compared. The study pointed out that the most important factors in the cesium bioaccumulation process occurring in plants are related to morphology. The highest CF values were obtained in algae Polysiphonia fucoides, Ectocarpus siliculosus and Cladophora glomerata. Decidedly lower CF values were observed in the vascular plants and macrozoobenthos representatives.

Texto completo da fonteResumo:
The macrofauna in the intertidal zone of sandy beaches provides the trophic connectivity between land and sea, by linking microbiome, meiofauna, and megafauna, representing a food source for several terrestrial animals, including shorebirds and mammals. However, the macrozoobenthos in urbanised beaches is subjected to intense disturbances, such as breakwater barriers and tourism, which limit or impede the energy transfer from the marine to the terrestrial habitats. Because the information about diversity and abundance of the macrozoobenthos of the intertidal zone on the Mediterranean sandy coasts is scant, the main objective of this study is to increase the knowledge on the macrofauna living in this habitat and to identify taxa sensitive to cumulative human-induced stresses. To achieve this purpose, the structure and dynamics of macrozoobenthic communities from (1) a highly frequented beach characterized by breakwater barriers and (2) a marine protected area (MPA) in the Adriatic Sea were compared. The hypotheses that macrofauna composition and abundance changed in the two sites and over time were tested. Results highlighted that the macrozoobenthos in the MPA is mainly dominated by juvenile bivalves, which peaked from autumn to winter, and to a lesser extent by ostracods and mysids. Conversely, ostracods and the bivalve Lentidium mediterraneum (O. G. Costa, 1830) are particularly abundant in the highly disturbed beach, while the gastropod Tritia neritea (Linnaeus, 1758) increased only during summer. A possible combined effect of breakwater barriers and intense trampling has been theorized to explain the main differences between the two sites especially in the summer.

The results of studies on the distribution of alien species in macrozoobenthic communities in the reservoirs of the Kama River cascade are provided. Twenty five alien species of the Ponto-Caspian and Ponto-Azov origins and 1 species - a representative of the Lake Baikal fauna - were registered. Differences in the species composition and structural characteristics of invaders of macrozoobenthos in the Kama and Volga reservoirs were shown. It was noted that mollusks of the genus Dreissena dominate in biomass in most of the studied biotopes. Three types of coenotic complexes of alien species have been identified: psammorelophilic profundal, characteristic for the Nizhnekamsk Reservoir and the Volgo-Kamsky and Kamsky reaches of the Kuibyshev Reservoir; the psammorelophilic coastal in Nizhnekamsk Reservoir; and the psammorelophilic coastal in Votkinsk and Kama reservoirs.

Texto completo da fonteResumo:
The coastal intertidal ecosystem of the Bijagós Archipelago, Guinea-Bissau, one of the largest and most important in West Africa, sustains a considerable proportion of the migratory shorebird populations of the East Atlantic Flyway and operates as a nursery area for benthic fish in the region. The macrozoobenthos in these mudflats constitute the main food source for both groups so that spatial and temporal variation in their abundance and community composition is likely to influence the abundance and distribution of fish and birds. In this study we described the spatial and temporal dynamics in the density, biomass, and community composition of macrozoobenthos across six intertidal flats in three islands of the Bijagós Archipelago. Overall, the Bijagós Archipelago was characterised by a highly species-rich macrozoobenthic community, with ca. 88 taxa identified across all sites, reaching a mean density of 1871 ± 58.3 ind.m-2 (mean ± SE) and mean biomass of 5.65 ± 0.41 g of AFDM.m-2 (ash-free dry mass per m2), values much lower than what was described for nearby intertidal areas, namely the Band d’Arguin, Mauritania. Density and biomass of major macrozoobenthos classes (Bivalvia, Polychaeta, Malacostraca and Gastropoda) differed across sites and months, displaying an overall increase in density towards the final months of the dry season (March and April). Similarly, community composition also differed significantly between sites and throughout the season. The site with most distinct community composition (Adonga) supported low diversity and high abundance of a few bivalve species, whilst other two sites that hosted the most diverse communities, were also the most similar between them (Anrumai and Abu). These spatial and temporal patterns constitute an important baseline to improve knowledge of this intertidal ecosystem and will contribute towards a better understanding of the spatial and temporal distribution patterns of their consumers.

Responses of the macrozoobenthic community to an ecological restoration activity in the northern Venice lagoon were studied, within the scope of the project LIFE SEagrass RESTOration aimed at recreating aquatic phanerogam meadows largely reduced in recent decades. Transplants were successful in almost all project areas. Macrozoobenthos was sampled in eight stations before (2014) and after (2015, 2016, 2017) transplanting activities. An increase in abundance and fluctuations in richness and univariate ecological indices (Shannon’s, Margalef’s, Pielou’s indices) resulted during the years. Comparing non-vegetated and vegetated samples in 2017, every index except Pielou’s increased in the latter. Multivariate analysis (hierarchical cluster analysis, MDS, PERMDISP, SIMPER) grouped samples by localization rather than years, with differences between stations due to the abundance of common species. In 2017, results were also grouped by the presence or absence of aquatic plants, with differences in the abundance of grazer and filter-feeding species. Results of ecological index M-AMBI depicted conditions from moderate to good ecological status (sensu Dir.2000/60/EC) with similar fluctuations, as presented by univariate indices from 2014 to 2017. Responses of the macrozoobenthic community were more evident when comparing vegetated and non-vegetated samples, with the vegetated areas sustaining communities with greater abundance and diversity than non-vegetated samples, thus demonstrating the supporting function of aquatic plants to benthic communities.

Texto completo da fonteResumo:
The fauna of the stream water in the Lower Shakuranskaya Cave in central Abkhazia, western Caucasus, was studied. This cave has a large inlet and an extended entrance ecotone area of approximately 60 m, which makes it a convenient area for studying macrozoobenthic assemblages across a gradient of environmental factors. The cave has 13 species of stygobionts, 10 species of stygophiles and 18 species of stygoxenes. The number of species and the abundance and biomass of stygobionts per station were the highest near the boundary of the photic zone, at a distance of 50–60 m from the entrance to the cave, and gradually decreased toward both the remote parts of the cavity and the cave exit. The most abundant stygobionts were gastropod mollusks of the Hydrobiidae family, and Xiphocaridinella shrimp comprised the main part of the biomass. It has been shown that the main environmental factors determining the distribution of macrozoobenthos are luminosity and distance from the entrance to a cave. According to the differences in their reactions to these environmental factors, several groups of species were identified. In addition, three main assemblages of macrozoobenthic species were described: (1) an assemblage of epigean species near the cave entrance area; (2) stygobionts in remote parts of the cave outside the photic zone; and (3) a mixed assemblage in the cave ecotone, where a faint light penetrates. The specific details related to the faunal structure in the ecotone of the cave are discussed, as well as active and passive methods by which stygoxenes invade underground cavities.

A comprehensive set of physicochemical variables in near-bottom water and surface sediments, as well as the soft-bottom macrozoobenthic assemblages were investigated at six sites across the Yundang Lagoon (Southeast China) in November 2012. This lagoon was severely damaged in the 1970s due to domestic and industrial pollution and land reclamation and underwent a massive restoration effort over the past 30 years. Our objectives were to: (1) assess the current trophic and environmental condition of the lagoon; (2) investigate the pattern of spatial variation in the macrozoobenthic assemblages; and (3) assess the benthic recovery in relation to the main environmental gradients and the presence of invasive alien species. Nutrient, chlorophyll-a, biological oxygen demand (BOD5), chemical oxygen demand (CODMn), and total organic carbon (TOC) concentrations were lower than those reported in previous decades, yet organically-enriched conditions occurred at an inner site. From azoic conditions in the 1980s and a few benthic species reported prior to this study, we found a significant increase in benthic diversity with 43 species heterogeneously distributed across the lagoon. The invasive bivalve Mytilopsis sallei was the dominant species, which was associated with the richest benthic assemblage. However, M. sallei is a pest species, and its spatiotemporal distribution should be carefully monitored. These results highlight the central role of the macrozoobenthos in providing important ecological information on the current status of the Yundang Lagoon and as an effective biological tool to follow the recovery’s progress and the future evolution of this highly valued ecosystem.

Pari tidak ada jenis gastropoda ataupun bivalvia yang mendominasi, namun hubungan keduanya mengikuti kerapatan mangrove yang ada dengan nilai korelasi keduanya sebesar 0,8061.Jenis yang lebih beragam dan kelimpahan jenisnya lebih dipengaruhi oleh kerapatan mangrove sebagai tempat hidupnya. Macrozoobethos as a biological indicators aside as a sessile organisms, its also have relatively long life cycle. Gastropod and bivalvia class, are commonly have a high abundance and diversity, its always responds to the water quality conditions in their habitat. The aim of study is to analized macrozoobenthic community structure and their relationship to mangrove ecosystem at Pari Island. Purposive random sampling was used for sampling the organisms by comparing to the density and species of mangrove vegetation. Square plots of 10 x 10 and 5 x 5 m were used to calculate macrozoobenthos abundance (gastropods and bivalvia) meanwhile the identification of Gastropods and Bivalvia is in LIPI laboratory at Cibinong. The results shows that mangrove density is in between 1,200 to 2,700 inds/Ha, while composition of macrozoobenthos at Pari Island have 10 species of gastropods and one species of bivalvia. The diversity of the two classes is included into the medium category (1.20-2.67), with moderate uniformity (0.59-0.84) and the dominance index is between 0.20-0.47. The regression analysis of the relationship between mangrove and macrozoobenthic abundance is about 0.6498. It can be concluded that in the Pari Island’s mangrove area, there are no gastropods or bivalves that much dominate, but the relationship between of Gastropoda and Bivalvia is following the mangrove density with a correlation about 0.8061. More diverse types and abundance of species are affected by the density of mangroves as a place for its live.

Diversity and habitat characteristics of macrozoobenthos in the mangrove forest of Lubuk Kertang Village, North Sumatra, Indonesia. Biodiversitas 19: 311-317. Mangrove plays an important role in coastal ecosystems including ecological, social, and economic aspects. This study aimed to determine the diversity of macrozoobenthos and water quality based on diversity index (H’), similarity Index (E), and dominance index (D) in the mangrove of Lubuk Kertang Village North Sumatra, Indonesia. The samples of macrozoobenthos (biological parameter) and water quality (physical and chemical parameters) were collected from fifteen plots in three different stations. Macrozoobenthos were collected in 1 m × 1 m transect in the mangrove forest. The biota was taken by using a shovel, inserted into a plastic bag, and identified. Results showed that eight species of macrozoobenthos were found and classified into three classes of Gastropod, Bivalvia, and Malacostraca. The highest diversity index (H′) of macrozoobenthos was found at Station II (2.39), the highest evenness index (E) was located at Station I (0.54), and the highest dominance index (D) was found at Station II (0.34). Principal component analysis (PCA) was used to determine the habitat characteristics of macrozoobenthos. PCA confirmed that station III was a habitat with suitable characteristics for the life of macrozoobenthos indicating the negative axis. The present study suggested four parameters namely salinity, clay temperature, and dissolved oxygen that should be preserved to support the survival of macrozoobenthos in the mangrove forests.

Introduction. Underwater banks influence the distribution of fish due to the presence of certain habitats and feed resources, a significant part of which is produced in macrozoobenthos biocenoses formed in different biotopes. There exist very little data on the state and structure of the macrozoobenthos of Odes’ka and Dnistrovs’ka banks in the modern period. Aim. The purpose of the work was to determine the structure of macrozoobenthos groupings on different types of substrate of Odes’ka and Dnistrovs’ka banks in modern conditions. Methods. The material was collected in the districts of Odes’ka and Dnistrovs’ka banks with a 10×10 cm area quantitative accounting frame using light diving equipment. In the laboratory, the samples were processed in accordance with the generally accepted methodology. Mathematical data processing was carried out with the introduction of multivariate statistics methods. Results. On different types of the substrate of Odes’ka and Dnistrovs’ka banks, six communities of macrozoobenthos which significantly differed in structure were identified. The macrozoobenthos of Odes’ka Bank is characterized by high abundance, biomass and biodiversity indices compared to the macrozoobenthos of Dnistrovs’ka Bank. In the community of Mytilus galloprovincialis on Odes’ka Bank, species that were present in it before the period of intensive development of hypoxia were registered. In this community, the abundance of Mytilaster lineatus, Prionospio cirrifera increased, Alitta succinea was not found. The community of Chamelea gallina in Odes’ka Bank is characterized by high biomass and high abundance of Donax trunculus. Conclusion. The structure of macrozoobenthos communities in the area of the Odes’ka and Dnistrovs’ka banks is significantly different. Their state reflects the trend of structural changes in macrozoobenthos in the northwestern part of the Black Sea in the modern period.

This research was conducted at April 2019 in Waters of Purnama Dumai. The aim of the study was to analyze the content of organic sediment and macrozoobenthos abundance and the relationship of organic sediment with macrozoobenthos abundance. The method used was a survey method consisting of 4 stations with 3 replications at each station. Sampling was carried out in the field and then taken to the Marine Chemistry Laboratory for analysis of sediment and organic material fractions. The results showed that the average content of organic sediment material in Waters of Purnama Dumai is 66,47 % and the content of organic sediment material between different stations is not significantly different (P>0,05) while the abundance of macrozoobenthos is 32 ind/m2 and the abundance of macrozoobenthos between stations was not significantly different (P>0,05). The relationship between the organic matter content of sediments and the abundance of macrozoobenthos has a value (r) = 0,235797 which means it has a weak relationship.

Seagrass has several important ecological functions which protected some species of invertebrates such as crustaceans, bivalves, gastropods, echinoderms, and other marine organism. Seagrass have ecological processes, where any interaction of several biotic and environment components. One of the biotic components associated with seagrass is macrozoobenthos. This study aims to determine the type and abundance of macrozoobenthos, the value of ecological index and covering percentage of seagrass at Cemara Besar Island, Karimunjawa. This study was conducted at Cemara Besar Island, Karimunjawa. The method used in this study was survey method with descriptive data analysis. Measurement of seagrass and macrozoobenthos using transect quadrant size of 1 x 1 meter. Macrozoobenthos living on the surface susbtrat (epifauna) was taken directly, while macrozoobenthos living within the substrate (infauna) using a corer was inserted into the substrate to a depth of 25cm. After conducting the samples were treated, the sediment sample sieved using benthos filter with a pore diameter of 1 mm and put macrozoobenthos into a sample bottle which has been given a 4% formalin solution and dye rose bengal, then identification of macrozoobenthos using a microscope and magnifying glass. Macrozoobenthos samples were analyzed using the calculation of abundance, the diversity index, the evenness index and the domination index. The result show that, in seagrass ecosystems in Cemara Besar Island Karimunjawa was found 4 classes macrozoobenthos consisting of Bivalve 3 species, Polychaeta 5 speseies, Echinoidea 4 species, and Gastropoda 25 species. The value of abundance in marine protection zone ranging from 6.32 to 8.42 ind/dm3 and the value of abundance in utilization zone marine ranging from 6.85 to 7.37 ind/dm3. The value of diversity index in the marine protection zone ranging from 1.42 to 2.57 are included in the category of low to moderate, while in the Marine Utility Zone ranging from 3.26 to 3.47 are included in the high category. The value of evenness index in the marine protection zone (E = 0.61 to 0.74) and utility zone (E = 0.77 to 0.82) were included in the high category (E > 0.6) in the second zone. The value of domination index in the marine protection zone (C = 0.20 - 0.48) and utility zone (C = 0.13 - 0.17) indicates that there are not macrozoobenthos species dominates. The Percentage cover of seagrass in marine protection zone from 68.75 to 76.04%, while the percentage cover of seagrass in utility zone ranging from 59.38 to 65.63%.

The paper aims to present the results of the analysis of 20 macrozoobenthic samples collected in 2022 from the Romanian Black Sea shore. The depth of the sampling sites ranged between 12.3 m and 42 m, corresponding to the infralittoral and circalittoral zones. Qualitatively, 102 taxa of macrozoobenthos including 36 polychaetes, 25 crustaceans, 20 molluscs, 10 nemertians and 11 taxa representing other groups, were recorded. Polychaetes were predominantly abundant, representing 55.92% of density. Species such as Melinna palmata Grube, 1870, Heteromastus filiformis (Claparède, 1864) and Prionospio cirrifera Wirén, 1883 recorded the highest densities. Among crustaceans, the most abundant species were Ampelisca diadema (Costa, 1853), Phtisica marina Slabber, 1749 and Medicorophium runcicorne (Della Valle, 1893). The molluscs Abra prismatica (Montagu, 1808), Spisula subtruncata (da Costa, 1778) and Polititapes aureus (Gmelin, 1791) were considerably abundant as well. The average density of the benthic populations was 1571 indv/m2 . By far the highest densities were recorded at two sites located close to the Danube’s Sf. Gheorghe mouth, at depths of 12.3 m and 19.9 m, represented 18.40%, respectively 16.42% of the total average density. The other sites recorded densities not greater than 6%. The average biomass was 236.54 g/m2 and was dominated by molluscs (90.74%). Among stations, Sf. Gheorghe (40.1 m) recorded the highest biomass, representing 42.60% of the total average biomass.
