Abstract:
The paper analyses the effects of heavy metals on freshwater fishes. From the point of view of pollution caused by heavy metals, the condition of ecosystems in Lithuania is yet less affected by heavy metals compared to that the world over. Fishes accumulate heavy metals selectively. Fishes mostly accumulate Pb, Cr, Cd. Our experiments showed that MPC (Maximum Permitted Concentration) (0.2 mg/kg) of lead was exceeded 1.6 time in the muscles of perch, and 1.4 time ‐ in the muscles of roach. The MPC (0.05 mg/kg) of cadmium was exceeded 1.2 time in the muscles of perch and roach. It was determined that perch accumulate heavy metals more intensively than roach. Heavy metals accumulate in fishes: liver > muscle> gills. As heavy metals are considered to be one of the most harmful water pollutants, there is a great need for a constant ecological monitoring and reduction of their amounts released into the environment. According to long‐term research data, the MPC in fishes is exceeded only slightly. This confirms a good condition of aquatic ecosystems in Lithuania. Santrauka Įvertintas sunkiųjų metalų pasiskirstymas gėlavandenių žuvų audiniuose monitoringiniuose vandens telkiniuose, taip pat ir kuojų bei ešerių, paveiktų sunkiųjų metalų didžiausiomis leidžiamosiomis koncentracijomis (DLK), audiniuose. Eksperimentiniai tyrimai atlikti su Cu, Zn, Ni, Cr, Pb, Cd, kurių kiekvienas pasižymi kancerogeniniu mutageniniu poveikiu. Nustatyta, kad švino DLK (0,2 mg/kg) buvo viršyta ešerių raumenyse 1,6 karto, o kuojų – 1,4 karto. Kadmio DLK (0,05 mg/kg) ešerių ir kuojų raumenyse buvo viršyta apie 1,2 karto. Taip pat nustatyta, kad ešeriai sunkiuosius metalus kaupia intensyviau nei kuojos. Eksperimentiniai duomenys sutampa su sunkiųjų metalų tyrimų monitoringiniuose vandens telkiniuose duomenimis. Žuvų audiniuose Pb ir Cd koncentracijos yra didžiausios ir dažnai viršija Lietuvos higienos normoje nurodytąją DLK. Tokie rezultatai įpareigoja nuolat kontroliuoti sunkiųjų metalų kiekį žuvyse. Rezultatai pateikiami sunkiųjų metalų sklaidos pasiskirstymo grafikuose. Резюме Представлены данные по распределению тяжелых металлов в тканях пресноводных рыб в мониторинговых водоемах, а также результаты, полученные путем воздействия тяжелых металлов в предельно допустимых концентрациях (ПДК) на окуня и плотву. В экспериментальных исследованиях применялись металлы Cu, Zn, Ni, Cr, Pb, Cd, оказывающие на живые организмы воздействие мутагенного и канцерогенного характера. Установлено, что концентрация Cd в тканях окуня превышала ПДК (0,2 мг/кг) в 1,6 раза, а в тканях плотвы – в 1,4 раза. Концентрация Cd в тканях тех же рыб превышала ПДК (0,05 мг/кг) примерно в 1,2 раза. Также установлено, что окунь аккумулирует тяжелые металлы интенсивнее плотвы. Экспериментальные данные совпадают с данными, полученными в мониторинговых водоемах. Установлено также, что концентрация Pb и Cd в тканях рыб зачастую превышает ПДК. Полученные результаты обязывают постоянно контролировать уровень тяжелых металлов в тканях рыб.

Abstract:
An immense amount of data is available on biomarkers related to different eco-toxicants. But data on contaminant-specific biomarkers in fishes is sparse. Traditionally, detection and quantification of heavy metals in sediment, water, and biota gave us valuable information on the quantity and the type of heavy metal present in the ecosystem. This information can be utilized to select a heavy metal specific biomarker. For an instance, if Cadmium (Cd), Zinc (Zn) and Cupper (Cu) are at high concentration, then Metallothionein (MT) can be a good candidate biomarker. Along with this, Superoxide dismutase (SOD) is a very potent indicator of Iron (Fe) and Mercury (Hg) contamination and also Catalase (CAT) is specific for Cadmium (Cd) and Zinc (Zn) exposure. For these kinds of selection of biomarker, the researchers should know heavy metals type specific biomarker. This review is the small effort towards cumulating the heavy metals type specific biomarker. This demonstrates the exposure and effects of heavy metals in fishes by integrating the heavy metal quantification and biomarker selection.

Abstract:
In this review, the fish Metallothionein (MT) is broadly discussed in relation to their utilization as a biomarker to assess the heavy metal contamination in marine ecosystem. Heavy metals are the main marine pollutants whose bioaccumulation in fishes results in deleterious effects on physiology, biochemistry and behavior. To assess the health status of fishes, an early determination of metal levels along with a biomarker like MT will help us to understand the bioavailability and toxicity of the metals. MTs constitute a family of low-molecular-weight, cysteine-rich proteins functioning in the regulation of essential metals and detoxification of both essential and nonessential metals. Since 1980, MT has been the useful tool for toxicity assessment of metals before sub lethal and lethal damage to organisms because of quick induction of MTs as metals enter the tissue. Various studies conducted on the induction, regulation and estimation of the MT by the metals showed that many variables such as sexual maturity, age, tissue type, metal type, route of exposure, changes in the environmental conditions of the living habitat of the organisms under study and presence of exogenous and endogenous substances do create fluctuations in the level of MT. Keeping in view of the above factors, this review attempts to understand the effectiveness of this biomarker in assessing the health status of the fishes.

Abstract:
Introduction: Heavy metal contamination of aquatic ecosystems has been a serious concern throughout the world for many decades, and has caused devastating effects on aquatic organisms. Objective: To evaluate the levels of Cu, Zn, Fe, Pb and Cd in the kidneys of scaly (T. zillii, M. rume and R. ocellatus) and non-scaly (C. gariepinus, Ch. nigrodigitatus and S. filamentosus) fishes in Epe lagoon, Nigeria to understanding the bioaccumulation potential of the kidney relative to other organs in fish that have previously been reported in literature. Methods: We studied concentrations of copper (Cu), iron (Fe), zinc (Zn), cadmium (Cd) and lead (Pb) in the kidneys of 141 scaly fishes (Mo. rume, R. occellatus, T. zillii) and 134 non-scaly fishes (C. gariepinus, S.filamentosus, Ch. nigrodigitatus) and water samples obtained from Epe Lagoon using Standard Atomic Absorption Spectrometry methods. Results: The kidneys of R. ocellatus had the highest levels of Fe (2,92±0,10) and Cd (0,18±0,03), while that of Ch. nigrodigitatus (2,78±0,02) and T. zillii (0,31±0,02) had the lowest concentration of Fe and Cd respectively. T. zillii and M. rume accumulated Cu and Zn in their kidneys respectively more than the others. There was no significant difference (p<0,05) in mean trace metal concentrations among the scaly and non-scaly fishes. The concentrations of metals in fish specimens were below the FEPA and WHO prescribed maximum allowable limits in food fish. Dissolved oxygen (9,0±0,02) and total alkalinity (24,0±0,01) were above FEPA values (dissolved oxygen: 3,0-5,0mg/L and total alkalinity: 3,05-5,3mg/L). The ranking of heavy metals distribution in the water body was Cu (4,70)>Fe (0,72)>Zn (0,13)>Pb (0,007)>Cd (0,006). Bioconcentration factor of Zn was generally high in all species. Conclusion: Close monitoring of these metals in the fishes and the lagoon is important to ensure the safety of fish consumers in the area.

Abstract:
Heavy metals are non-biodegradable substances which cause serious carcinogenic effects on animals and humans. As fish occupy top position of aquatic food chain, it is a major source of heavy metal contamination. The concentration of Cd, Cr, Pb, Mn, Fe, Cu, and Zn were 0.0156 - 0.1428, 0.163 - 8.53, 0.0924 - 0.4026, 9.38 - 65.9382, 0.0473 - 0.1981 and 0.1473 - 1.8148 ppm respectively for the fish samples of Cox’s Bazar region while 0.0191 - 0.1386, 0.8445 - 0.1743, 0.102 - 0.4625, 0.102 - 0.4675, 9.7269 - 60.5267, 0.3108 - 0.046 ppm for the fish samples of Saint Martin’s region. Comparatively high concentrations of heavy metals were found to be accumulated in Mola (Amblypharyngodon mola), Rupchanda (Stromateus chinensis) and Chhuri (Trichiurus lepturus). The order of heavy metal concentrations were Fe > Zn > Cr > Cu > Mn > Cd. The concentration of heavy metals varied from species to species and most of the metals were not significantly correlated, even some metals showed negative correlation among them. Concentration of Fe in some fishes (Mola, Rupchanda and Chhuri) was found higher than WHO guideline values, while other metals exhibited the value below the WHO standard. The results of this study will assist in acquiring information about the level of toxic metals in these regions and to improve the coastal management in these areas in future. Bangladesh J.

Abstract:
The study was carried out to determine the concentration of heavy metals in some commonly used commercial fish feeds and to observe the bioaccumulation of Cr, Cu, Cd and Ni in liver, muscle and gills of tilapia Oreochromis niloticus after culturing them for 60 days by feeding those commercial feeds. The study revealed that the concentration of Cu was the highest (65.08 mg/kg) in handmade feed (B1) among four heavy metals. The concentrations of Cr in collected feeds were 1.75 to 3.04 mg/kg, which exceeds the permissible limit set by FAO. In cultured tilapia, the concentrations of studied heavy metals were found higher than initial concentration in fish feeds and in tilapia fingerlings. Metal levels in cultured fish followed the ranking of Cu>Cr>Ni>Cd and order in individual organs was liver>gill>muscle. The highest concentration of Cu (72.86 mg/kg) was found in liver given S feed and the lowest concentration (0.67 mg/kg) was in muscle receiving Q feed. Bioaccumulation of Cr was the highest (23.95 mg/kg) in liver taken B1 feed and the lowest (9.29 mg/kg) in muscle of tilapia cultured with C feed. Concentration of Cu exceeded the tolerable limit in fishes cultured with S and C feeds. But Cr concentration surpassed the allowable limit in every feed studied. The concentrations of Ni and Cd were below the permissible range approved by FAO. Considering the present study, tilapia cultured with these experimental feeds is not safe for human consumption. Higher concentration of these heavy metals exceeding allowable limit may cause harmful effect on human body after consumption of those fishes and can create cancer and other diseases in human body.Bangladesh J.

The present study was carried out to determine the sub lethal toxic effects of the heavy metal cadmium on the electrophoretic protein fractions of gill and muscle tissues ofOreochromis mossambicus. Fishes were exposed to 10% sub lethal concentration (96 h LC50) of cadmium for a period of 10 days. The protein fractions in the muscle of experimental fishes were found to be increased (twelve fractions) with respect to controls (eight fractions). The numbers of protein fractions in the gills of test fishes were found to be lesser than the control fishes. The results of the present study prove that cadmium affects the protein fractions in the tissues of fishes.

Abstract:
Complex physiological traits, such as routine aerobic metabolic rate or exercise performance, are indicators of the functional integrity of fish that can reveal sub-lethal toxicological effects of aquatic pollutants. These traits have proved valuable in laboratory investigations of the sub-lethal effects of heavy metals, ammonia and various xenobiotics. It is not known, however, whether they can also function as biomarkers of the complex potential range of effects upon overall functional integrity caused by exposure to mixtures of chemicals in polluted natural environments. The current study used portable swimming respirometers to compare exercise performance and respiratory metabolism of fish exposed in cages for three weeks to either clean or polluted sites on three urban European river systems: the river Lambro, Milan, Italy; the rivers Blythe, Cole and Tame, Birmingham, UK; and the river Amstel, Amsterdam, The Netherlands. The UK and Italian rivers were variously polluted with high levels of both bioavailable heavy metals and organics, and the Amstel by mixtures of bioavailable organics at high concentrations. In both the UK and Italy, indigenous chub ( Leuciscus cephalus ) exposed to clean or polluted sites swam equally well in an initial performance test, but the chub from polluted sites could not repeat this performance after a brief recovery interval. These animals were unable to raise the metabolic rate and allocate oxygen towards exercise in the second trial, an effect confirmed in successive campaigns in Italy. Swimming performance was therefore a biomarker indicator of pollutant exposure in chub exposed at these sites. Exposure to polluted sites on the river Amstel did not affect the repeat swimming performance of cultured cloned carp ( Cyprinus carpio ), indicating either a species-specific tolerance or relative absence of heavy metals. However, measurements of oxygen uptake during swimming revealed increased rates of routine aerobic metabolism in both chub and carp at polluted sites in all of the rivers studied, indicating a sub-lethal metabolic loading effect. Therefore, the physiological traits of exercise performance and metabolic rate have potential as biomarkers of the overall sub-lethal toxic effects of exposure to complex mixtures of pollutants in rivers, and may also provide insight into why fish do not colonize some polluted environments.

Abstract:
The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a better understanding of the distribution of contaminants in the Trinity River.

Abstract:
The detection of anthropogenic impacts in our estuaries has become a critical social, political and scientific concern in recent years. Work has focussed on the effects of these impacts on the spatial and temporal patterns of biotic assemblages and searched for bioindicators and biomarkers of pollutants that may act as early warning signs. The estuaries in temperate Southeastern Australia have a diversity of biotic assemblages living in the soft sediment. One of the most abundant macroinvertebrates is the little studies mussel, Xenostrobus securi that is found living with an assemblage of benthic biota including amphipods, crabs, isopods and tanaids, bivalves and gastropods. Two commercial fish species bream and mullet also inhabit these estuaries. Numerous stormwater drains can be found entering the estuaries through the mangrove forests lining the shores. Along with inputs of freshwater, stormwater drains are thought to be responsible for the entry of heavy metals into estuaries. These heavy metals have the potential to alter the patterns of biotic assemblages and bioaccumulate in the tissues of miacroinvertebrates, mussels and fish living within temperate estuaries. Over the time of this study the concentrations of heavy metals in the sediment tissues and shell of X.Securis varies spatially and temporally. Although this study adds substantially to current knowledge there is still more that is needed to establish X. Securis as a bioindicator. Questions remain about uptake, depuration and response to environmental gradients of heavy metals in X. Securis. Before X Securis can be used routinely in monitoring heavy metal contamination these questions need to be further investigated

Abstract:
Oogenesis is examined in two rockling species. Seven developmental stages are described in Ciliata mustela L. and six stages in Gairdropsarus mediterraneus L., since both species were collected at the same time, suggesting the possibility of an earlier spawning in the first species. Ultrastructural differences in the zona radiata occur, monopartite in G. mediterraneus and bipartite and double thickness in C. mustela. Cortical alveoli are first formed in the cortex originating from Golgi vesicles. Ultrastructural evidence suggests that protein yolk formation has a contribution from both exogenous and endogenous sources while lipid yolk is solely endogenous. The endogenous protein is synthesised by Golgi complexes. Lipid yolk is formed in close association with rough endoplasmic reticulum in G. mediterraneus and annulate lamellae in C. mustela suggesting that both organelles play a role in lipid formation. Fertilised eggs of Clupea harengus L. were exposed to different acid pHs. Egg, perivitelline space, and yolk volumes were measured in relation to osmoregulation. The effect of acid on the morphology of the hatched larvae was also demonstrated. Jaw, branchial and skeletal abnormalities were observed. Exophthalmus condition was recorded in these larvae. Acid water causes epidermal necrosis, degeneration of the chloride cells, and swelling of the membrane-bound structures of the trunk muscle tissue at the ultrastructural level. The study demonstrates that aluminium is extremely toxic at pH 5.0 causing 99.52% cumulative mortality to C. harengus eggs. Ultrastructural and morphometric evidence show that aluminium causes disruption and swelling in the cell membranes of the brain and muscle tissues of C. harengus larvae accompanied by degeneration of mitochondrial cristae. Such effects would reduce the metabolic activity and survival potential of these larvae with subsequent consequences on recruitment success of the stock.

Abstract:
Tissue samples from spotted gar (Lepisosteus oculatus) and largemouth bass (Micropterus salmoides) were collected from Caddo Lake. Gar and bass livers were subjected to histological investigation and color analysis. Liver color (as abs at 400 nm) was significantly correlated with total mercury in the liver (r2 = 0.57, p = 0.02) and muscle (r2 = 0.58, p = 0.01) of gar. Evidence of liver damage as lipofuscin and discoloration was found in both species but only correlated with liver mercury concentration in spotted gar. Inorganic mercury was the predominant form in gar livers. In order to determine the role of mercury speciation in fish liver damage, a laboratory feeding study was employed. Zebrafish (Danio rerio) were fed either a control (0.12 ± 0.002 µg Hg.g-1 dry wt), inorganic mercury (5.03 ± 0.309 µg Hg.g-1 dry wt), or methylmercury (4.11 ± 0.146 µg Hg.g-1 dry wt) diet. After 78 days of feeding, total mercury was highest in the carcass of zebrafish fed methylmercury (12.49 ± 0.369 µg Hg.g-1 dry wt), intermediate in those fed inorganic mercury (1.09 ± 0.117 µg Hg.g-1 dry wt), and lowest in fish fed the control diet (0.48 ± 0.038 µg Hg.g-1 dry wt). Total mercury was highest in the viscera of methylmercury fed zebrafish (11.6 ± 1.86 µg Hg.g-1 dry wt), intermediate in those fed inorganic diets (4.3 ± 1.08 µg Hg.g-1 dry wt), and lowest in the control fish (below limit of detection). Total mercury was negatively associated with fish length and weight in methylmercury fed fish. Condition factor was not associated with total mercury and might not be the best measure of fitness for these fish. No liver pathologies were observed in zebrafish from any treatment.

Abstract:
In this study, the ecosystem marine water-sediment-biota was investigated and the pollution was assessed. The concentrations of eight elements were determined in marine water, sediments and four fish species collected from Black Sea (Varna), Bulgaria during 2013. Marine water recorded the highest concentrations of Zn (15-22 μg/L), As (1.1–1.2 μg/L) and Pb (0.7-0.8 μg/L) while Zn (31-52 μg/g), Pb (21-29 μg/g) and Cu (20-34 μg/g) and show the highest concentrations in sediments. Water and sediments showed similar spatial distribution patterns for the highest mean values of the different metals. In the analysed fish species, the highest concentration of the metals Cu and Zn were found in Trachurus Mediterrneus (0.42 mg/kg w.w) and in Sprattus Sprattus (12.7 mg/kg w.w), respectively while the heavy metals As and Hg were found with maximum values in Pseta Maxima (3.99 mg/kg w.w and 0.08 mg/kg w.w respectively). The results from this study were compared with our data for a previous period (2004-2006) and they show decrease in the levels of heavy metal.

Abstract:
The aim of this study was to evaluate metals bioconcentration factor (BCF) in gills, liver, kidneys and muscle in relation with genotoxicity effects of metal mixture in peripheral blood, kidneys, gills and liver erythrocytes of the Atlantic salmon (Salmo salar). Fish were exposed to maximum-permissible waterborne concentrations of Zn – 0.1, Cu – 0.01, Ni – 0.01, Cr – 0.01, Pb – 0.005 and Cd – 0.005 mg/L, respectively for 7 and 14 days. Genotoxicity was studied using the micronucleus test. In addition, erythrocyte nuclear abnormalities (ENAs) were analysed. Our study indicates that metal BCF in Atlantic salmon is tissue-dependent. Based on the BCF classification scale, the relatively low values of metals bioconcentration were assessed, except for Zn (gills) and Cu (liver) (359.6 and 594.0, respectively). Zn intensively concentrated in fish tissues, while Pb – least of all. Overall, metals were concentrated mostly in the liver, least – in the muscle. Significant differences among BCF values of Pb in gills and muscle and Cd in gills were measured between 7 and 14 d exposure groups. Treatment with metal mixture significantly increased micronucleus frequencies after 7 d of exposure in liver and peripheral blood erythrocytes. Significant genotoxicity response was not observed after 14 d treatment. The erythrocytic nuclei abnormalities determined in S. salar blood were nuclear bud on filament (NBf), nuclear bud (NB), blebbed (BL), kidney shaped, vacuolated (VacNuc), 8-shaped nuclei and fragmented-apoptotic (FA) erythrocytes. Significant elevation in total ENAs level was detected in kidneys and liver erythrocytes after 7 d treatment, while after 14 d – in gills and kidneys erythrocytes. No significant differences among analysed responses were measured between 7 and 14 d exposure groups, except total ENAs level in liver erythrocytes.
