Abstract:
<p>O objetivo do presente estudo foi elaborar <em>fishburger</em> de biquara (<em>Haemulon plumierii)</em> com intenção de agregar valor a uma espécie pesqueira pouco explorada utilizando diferentes porcentagens de agentes extensores: proteína texturizada de soja (PTS) - 1, 2 e 4% e amido de milho – 0, 1 e 2%, e avaliar aspectos físico-químicos (perda de peso na cocção, porcentagem de encolhimento, capacidade de retenção de água, cor objetiva e perfil de textura instrumental), nutricionais (umidade, proteína bruta, gordura, cinzas, carboidrato e valor calórico) e sensoriais (cor, odor, textura, sabor e aceitação global). O perfil de textura instrumental e a capacidade de retenção de água dos <em>fishburgers</em> não apresentaram diferença (P&gt;0,05) com a adição dos extensores. A partir das formulações com 2% de PTS e 1% de amido ocorreram menores (P&lt;0,05) perdas de peso após o cozimento. A cor dos <em>fishburgers</em> elaborados com adição de 4% de PTS e 2% de amido foram mais (P&lt;0,05) amarelados (maior valor de b*) que os demais tratamentos. A adição de 4% de PTS e 2% de amido causou diminuição (P&lt;0,05) da umidade e aumento (P&lt;0,05) do carboidrato e valor calórico dos <em>fishburgers</em>. A aceitação sensorial dos <em>fishburgers</em> foi alta, entre “gostei ligeiramente” a “gostei moderadamente”, em todos os quesitos avaliados, porém sem diferença (P&gt;0,05) entre a adição dos agentes extensores. Portanto, observa-se potencial de utilização da biquara como matéria-prima na elaboração de <em>fishburgers</em> com adição de 2% de PTS e 1% de amido de milho por melhorar alguns aspectos tecnológicos sem comprometer a qualidade nutricional e sensorial.</p>

Abstract:
Localizado a 48 km da cidade de Fortaleza, o distrito de Iguape possui uma pequena praia frequentada por moradores da região, sendo reduto de pescadores que trabalham de forma artesanal e tiram da pesca o seu sustento. Visto a importância que essa atividade econômica tem para a população local, o objetivo desta pesquisa foi caracterizar a pesca artesanal, analisar a biodiversidade da ictiofauna e saber quais aquelas que são de importância econômica para a comunidade. Os resultados mostraram que são utilizadas embarcações do tipo jangadas e paquetes a vela e botes a remo em pescarias de “ir e vir” e de “dormir”. As pescarias são realizadas com linha de mão, tarrafas e redes de espera. Foram capturados 2.655 espécimens, inseridos em duas classes, sete ordens, 18 famílias e 32 espécies, revelando uma elevada diversidade e riqueza de espécies, com destaque para Harengula clupeola, Opisthonema oglinum, Haemulon parra e Haemulon plumierii, que contribuem acentuadamente para a renda da comunidade pesqueira.Palavras-chave: atividade econômica, peixe marinho, embarcações.

Abstract:
La Reserva de la Biósfera Los Petenes (RBLP) se localiza en la costa de Campeche, en el Golfo de México. En este ecosistema destacan la fauna nectónica por su abundancia y diversidad, y la amplia cobertura de pastos marinos. El objetivo del presente trabajo fue analizar las asociaciones de los peces dominantes en un marco de variabilidad ambiental temporal (época de secas y época de lluvias) y nictemeral (día y noche). Se realizaron seis campañas de muestreo entre diciembre 2010 y octubre 2011, en un sitio ubicado cerca de Isla Jaina en la región central de la RBLP. Se recolectaron muestras biológicas cada 2 h en un período de 24 h y se realizaron mediciones de temperatura, salinidad, oxígeno disuelto y pH del agua. Se identificaron todos los peces, determinando a las especies dominantes. Las asociaciones interespecíficas y las relaciones entre abundancia y variables ambientales se establecieron mediante técnicas estadísticas de clasificación y ordenación. Se capturaron 10 602 peces con un peso conjunto de 163.62 kg, identificando 44 especies, agrupadas en 33 géneros y 23 familias, de las cuales, 14 resultaron dominantes, destacando la abundancia de Haemulon plumierii. Los dendrogramas específicos construidos por época climática y ciclo nictemeral permitieron identificar tres grupos funcionales. El análisis de correspondencias canónicas para la época de secas destacó relaciones entre salinidad y pH con la abundancia de Eucinostomus gula, Acanthostracion quadricornis y Haemulon aurolineatum. En la época de lluvias, se asoció el oxígeno disuelto con Lagodon rhomboides. No se encontraron diferencias significativas entre las agrupaciones por época climática.

Abstract:
The current study examined the stomach contents of the Atlantic sharpnose shark (Rhizoprionodon terraenovae) in the southern Gulf of Mexico during 2015 to understand the relationship between diet and changes in sea surface temperature (SST). Prey-specific index of relative importance (%PSIRI), diet breadth (Bi), trophic level (TrL), and trophic overlap (PERMANOVA) were calculated between sexes, body size, and climatic seasons (dry, rainy and winter storm). The lowest temperature recorded in the area was during February (23.9°C), and the highest was during August (29.1°C). A total of 124 stomachs were analyzed, with 54.84% containing food. The trophic spectrum was composed of 32 identified prey, with demersal fish (Haemulon plumierii; %PSIRI = 22.82) and pelagic fish (Sardinella aurita; %PSIRI = 12.83) being the most important. According to the diet breadth (Bi = 0.002), Costello's graph, and trophic level (TrL = 4.2), R. terraenovae is a specialist tertiary consumer. PERMANOVA indicated significant trophic differences between sexes (F = 32.22; P < 0.05), body size (F = 13.68; P < 0.05), and among climatic seasons (F = 23.86; P < 0.05). Spearman's correlation indicated a negative relationship between the diversity of prey consumed by R. terraenovae and sea surface temperature (r = -0.75; P < 0.05). Therefore, diet for R. terraenovae is associated with SST, allowing for the development of possible scenarios related to climatic phenomena like climate change.

Abstract:
It is commonly assumed in surveys that the likelihood of capturing or observing individuals of a given species is constant. Yet evidence is building that catchability, or the likelihood of catching an individual present at a site, can vary. We used 5465 paired trap-video samples collected along the southeast US Atlantic coast in 2015-2018 to estimate trap catchabilities of 6 reef fish species (gray triggerfish Balistes capriscus, red porgy Pagrus pagrus, vermilion snapper Rhomboplites aurorubens, black sea bass Centropristis striata, red snapper Lutjanus campechanus, white grunt Haemulon plumierii) as the ratio of trap catch to standardized site abundance from corresponding videos. Species-specific trap catchabilities were then related to 2 primary predictor variables: water temperature and percent of the visible bottom consisting of rocky substrate. Water temperature strongly influenced trap catchabilities for all species after standardizing for all other variables. The 4 warm-water species displayed strong positive relationships between catchability and temperature; of these species, the smallest absolute increase in catchability occurred for vermilion snapper (0.0 at ~14°C to 0.05 at ~28°C) and the largest occurred for white grunt (0.0 at ~14°C to 0.49 at ~28°C). The 2 cooler-water species displayed either a dome-shaped (red porgy) or negative relationship (black sea bass) between catchability and temperature. Furthermore, trap catchabilities for all species declined substantially (42-80%) as the percent hard bottom of the site increased. Only when catchability is properly accounted for can results be considered unbiased and subsequent management advice be considered accurate.

Abstract:
The Haemulon plumieri is a typical reef-associated and tropical species found in warm and temperate waters of the Western Atlantic. Due to the large fishing effort directed to H. plumieri, the knowledge about its reproductive biology is essential for correct stock management and conservation. The aim of this study was to characterise reproductive biology with a focus on its seasonal variation of gonadal maturation stages, first maturation size and fecundity. Specimens were monthly collected and a total of 119 females and 136 males were analysed. The reproductive cycle of Haemulon plumieri is seasonal, with higher activity between March and May. Size at first maturity (L50) was estimated at 16.86 and 18.55 cm for females and males, respectively. The total fecundity ranged between 17,816 and 120,333 mature oocytes per female and relative fecundity was 235 ± 63 oocyte.g−1 whereas batch fecundity varied between 20 and 25% from total fecundity. Since the species is widely caught, we suggest a closed season from March to May and to establish a minimum catch size of 18.5 cm for both sexes, since there is no evident sexual dimorphism.

Abstract:
In this study, the population structure of the white grunt (Haemulon plumieri) from the northern coast of the Yucatan Peninsula was determined through an otolith shape analysis based on the samples collected in three locations: Celestún (N 20°49’,W 90°25’), Dzilam (N 21°23’, W 88°54’) and Cancún (N 21°21’,W 86°52’). The otolith outline was based on the elliptic Fourier descriptors, which indicated that the H. plumieri population in the northern coast of the Yucatan Peninsula is composed of three geographically delimited units (Celestún, Dzilam, and Cancún). Significant differences were observed in mean otolith shapes among all samples (PERMANOVA; F2, 99 = 11.20, P = 0.0002), and the subsequent pairwise comparisons showed that all samples were significantly differently from each other. Samples do not belong to a unique white grunt population, and results suggest that they might represent a structured population along the northern coast of the Yucatan Peninsula. En este estudio, la estructura de la población del ronco blanco (Haemulon plumieri) de la costa norte de la Península de Yucatán fue determinada a través del análisis de la forma del otolito, sobre la base de las muestras recolectadas en tres localidades: Celestún (N 20°49’, W 90°25’), Dzilam (N 21°23’, W 88°54’) y Cancún (N 21° 21’, O 86° 52’). El análisis del contorno de los otolitos se basó en los descriptores elípticos de Fourier, cuyo enfoque indicó que la población de H. plumieri en la costa norte de la Península de Yucatán se compone al menos de tres unidades delimitadas geográficamente (Celestún, Dzilam y Cancún). Se observaron diferencias significativas en la forma del otolito entre todas las muestras (PERMANOVA, F2, 99 = 11.20, P = 0.0002) y las comparaciones por pares posteriores indicaron que todas las muestras fueron significativamente diferentes una de otra. Al parecer, las muestras no pertenecen a una única población, y los resultados sugieren que podría representar una población bien estructurada a lo largo de la costa norte de la Península de Yucatán.

Abstract:
To elucidate the reproductive cycle of any animal, it is first necessary to understand the development of the germ cells and how this process occurs throughout the reproductive tract. Thus, the aim of the present study was to understand the oogenesis and spermatogenesis, as well as the ovarian and testis maturation and type of spawning, of Haemulon plumieri. A total of 119 females and 136 males were analysed. Based on micro and macroscopic characteristics of gonads, the following stages of maturation for females were determined: immature, maturing, ripe, partially spawning, spawning and resting. For males, only the stages immature, maturing, ripe and spent were observed. We can conclude that the ovarian development occurs cyclically, in which the female can spawn more than two times during the reproductive season with the spawning “synchronous in more than two groups”. Since males do not present the “rest” stage after copulation, the maturation process is continuous.

Abstract:
Sportfishing is an activity of increasing popularity that involves a large number of users and high levels of fishing effort. In Yucatan, most of the target species in sport fishing are the same as those of commercial fisheries. However, there is no record of fishing effort or catch volumes. Thus the impact of sport fishing on these populations is unknown. This study analyzes the catches made by users of sport fisheries of nine species (Epinephelus morio, Haemulon plumieri, Seriola dumerili, Lutjanus synagris, Ocyurus chrysurus, Calamus bajonado, Sphyraena barracuda, S. guachancho and Mycteroperca bonaci) through length-based indicators. Samples of species’ sizes were obtained from the catches made during 10 fishing tournaments held in Yucatan's three-port towns (Sisal, Yucalpeten, and Telchac) between 2015 and 2016. The catch variables that were evaluated included: the number of mature individuals Pmat, optimal length Popt, and the number of mega-spawners Pmega. Length measures were derived from 1,252 individuals. Only H. plumieri, L. synagris, and S. guachancho exhibited sustainable indicator values, while E. morio and C. bajonado demonstrated extremely low values. In most species, sport fishing affects a high proportion of juveniles. The results suggest that sportfishing contributes to the fishing pressure of a species and commercial fishing, due to the capture of juveniles of economically important fish. It is essential to establish a systematic monitoring method of such activities and increase the priority level of the evaluation and management of this fishery.

Abstract:
Acetylcholine deficiency is a neurochemical characteristic of patients with clinical diagnosis of Alzheimer´s disease. Substances that inhibit the enzyme acetylcholinesterase, increasing levels of acetylcholine in the brain, are a promising form of treatment. Studies relate the use of omega-3 fatty acids in the treatment and prevention of Alzheimer's disease. The Northeast Region of Brazil has an enormous biological diversity and a wide variety of fish species. In this work, the oils of eleven species of marine fish found on the coast of Ceará, Brazil, were analyzed in relation to the fatty acid profile and the inhibitory activity of the enzyme acetylcholinesterase. Total lipids were extracted from fish samples by Folch metodology. The lipid extracts of the fish and industrialized fish oil, used for comparison, were esterified and fatty acid profiles were analyzed. The acetylcholinesterase inhibitory activity was measured quantitatively. The oils presented a high percentage of saturated fatty acids, which is a general characteristic of tropical fish. Oleic acid was the highest monounsaturated fatty acid. Oils of Scomberomorus cavalla, Lutjanus synagris and Haemulon plumieri presented expressive percentages of polyunsaturated fatty acids and the most potent anticholinesterase activities. This research showed the oils of S. cavalla, L. synagris and H. plumieri may be promising functional food products of active fatty acids as new therapies to treatment or prevention of Alzheimer's disease. The expressive concentration of unsaturated and polyunsaturated fatty acids together with their relevant anticholinesterase activity are characteristics of the importance of these fish oils.

AbstractDuring a parasitological survey of the reef ichthyofauna in the Caribbean coast of Mexico, parasitic siphonostomatoid copepods were obtained from the white grunt Haemulon plumierii (Lacepède) and the blue striped grunt H. sciurus (Shaw). Caligus haemulonis Krøyer, 1863 has been recorded from both species of Haemulon in the Northwestern Tropical Atlantic, but it is reported herein for the first time from Mexico. The prevalence and intensity of infection of C. haemulonis has not previously been evaluated in the Caribbean grunts; during this survey, prevalence was highest in H. sciurus; values are similar to those found in other haemulids. Lernanthropus chacchi sp. nov. can be distinguished from its closest congener, L. rathbuni Wilson, 1922, by its female having a dorsal plate covering the entire urosome and the lack of lateral notches at the base of the modified third legs, the male has relatively longer third legs, different body proportions and ornamentation of the first and second legs. This is the third species of Lernanthropus known from reef grunts in the Caribbean and the second species of the genus described from Mexican waters. The infection prevalence of the new species on H. sciurus (24%) was higher than that known for L. rathbuni from other haemulids. Taxonomic illustrations of females and males of both species are also provided. Other crustacean ectoparasites included the copepod Hatschekia spp. and praniza larvae of a gnathid isopod.

Abstract:
The abundance and size of reef fihes in presence of lionfih were evaluated in Morro de Santa Marta, Remanso, and Isla Aguja and Chengue and Cinto Bays in the Parque Nacional Natural Tayrona (PNNT). Some commercially important fih species (Lutjanus mahogoni, Cephalopholis cruentata, and Haemulon plumierii) and some fih species important for reef health (Abudefduf saxatilis, Chaetodon ocellatus, C. striatius, C. sedentarius, and C. capistratus) were evaluated monthly during 2012. Counting was carried upon using visual censuses along 30 x 10 m transects. The highest lionfih abundances were found at Morro (2.60 ± 2.12) and the lowest at Remanso (0.58 ± 1.16), however, no differences were found between localities (p > 0.05). Highest abundance was recorded in June and July and the lowest in March, September, and October; no lionfih was observed in February. The highest abundances of both, commercially important and reef health important species were detected in the PNNT localities. The smallest lionfih and H. plumierii specimens were found at Morro, Remanso, and Isla Aguja. The size of the species was similar for all localities and lionfih sizes where larger. This may indicate that the studied species are not large enough to compete and thus they may be displaced, likewise their low abundances may be due to other stress factors. In any case, the invader has not reach yet the abundances shown in other Caribbean regions and then it may not be still causing a negative effect on the reef community.

Abstract:
Las lagunas costeras son sistemas dominados por la variabilidad ambiental ocasionada por ciclos estacionales o nictémeros, lo cual influye directamente en la composición de especies como la de los peces. El objetivo de este estudio fue evaluar la variación en la composición de la comunidad de peces a 2 escalas temporales y analizar la dieta de especies marinas que utilizan la laguna en alguna etapa de su ciclo de vida. El estudio se realizó en la laguna Carbonera en la costa norte de Yucatán, México. Se recolectaron peces cada 2 h con un chinchorro playero durante un ciclo de 24 h, en campañas bimestrales de diciembre de 2010 a octubre de 2011. Las variables hidrológicas registradas y la comunidad de peces se evaluaron a escala nictémera y estacional, y se observaron cambios significativos en la temperatura y la salinidad. La riqueza específica y la diversidad de peces fueron mayores durante la noche, cuando se registraron especies marinas como los armados (Orthopristis chrysoptera), las corvinas (Bairdiella chrysoura), las mojarras (Eugerres plumieri) y los roncos (Haemulon plumierii). La mayor abundancia se obtuvo durante las horas de luz debido a la presencia de cardúmenes de juveniles de sardina (Harengula clupeola) y especies residentes (Floridichthys polyommus y Fundulus persimilis). Se analizó la alimentación de 10 especies de peces marinos en estadio juvenil, y se identificaron 4 principales gremios tróficos (piscívoros, detritívoros, malacófagos y zoobentófagos). Las especies marinas en estadio juvenil de importancia comercial que utilizan la laguna Carbonera para alimentación son las lisas, las sardinas y los roncos. Por lo tanto, este sistema brinda recursos a juveniles de especies de gran importancia para la pesca artesanal, por lo que es de suma importancia elaborar estrategias de manejo para su protección y conservación.

Abstract:
Objective: To determine the incidence of non-target fishing species, in riparianfishing, as a dietary alternative for the agricultural sector in the state of Campeche,Mexico.Design / methodology / approach: The ports surveyed in the state of Campeche:Champotón, Seybaplaya and Campeche. A total of 89 questionnaires were appliedat random and at the free will to participate to coastal fishermen. The obtained datawere analyzed with the R vr 3.4.4 statistical software.Results: The results showed that the coastal fishing catch is 760.1 kg onaverage/week, and fishing discards of 30.42 kg/week. Of the bycatch, 68.8% isdiscarded and the rest sold at a low price (US $ 0.2). Among the waste products,234 species stand out, but seven represent the 58.7% of maximum incidence,mainly Bosh Ariopsis felis, Chac-chi Haemulon plumierii, Cojinuda Caranx crysos,Ixpil Upeneus sp., Macabi Elops saurus, Postà Bairdiella chrysoura and SardinaHerengula jaguana.Delimitations / implications: There is a wide variety of species of which theirpotential as a protein source is unknown, which can be used as input in feed.Findings / conclusions: Registered fishing discards are made up of more than 30non-target species and according to their incidence can be considered as inputs infeed manufacturing for the agricultural sector.

Abstract:
Abstract The fishes of the Haemulidae family are currently allocated to 19 genera with a worldwide distribution in the tropical and subtropical waters of the world’s oceans. Brachygenys and Haemulon are important genera of reef fish in Brazil, as they occur in large shoals, which are both ecologically and commercially valuable. This study identified the Brazilian species of the genera Brachygenys and Haemulon using DNA barcodes. While we found only a single lineage in Brachygenys chrysargyrea, Haemulon melanurum, H. parra, and H. squamipinna, more than one molecular operational taxonomic unit (MOTU) was identified in H. atlanticus, H. aurolineatum, and H. plumieri, indicating the possible existence of discrete populations or cryptic species.

Abstract:
El corocoro margariteño Haemulon plumieri es muy abundante en la región nororiental de Venezuela, pero los aspectos biológicos y pesqueros han sido poco estudiados en el país. El objetivo de este estudio fue estimar el crecimiento y la mortalidad de este recurso. Se realizaron muestreos mensuales desde enero a diciembre 2014, obteniéndose 2 967 ejemplares y se registró la longitud total (cm) y peso (g) de cada ejemplar. Se encontró que no existe diferencia entre sexos con respecto a la longitud (ts = 0.093; P > 0.05), por lo que se estimó la relación longitud-peso para ambos sexos: P = 1.4x10-3 * L2.99, mostrando un crecimiento isométrico. Se utilizaron las rutinas del paquete FiSAT para estimar los parámetros del modelo de crecimiento individual de von Bertalanffy: L∞ = 30.95 cm, k = 0.67/año, P∞ = 418.17 g, t0 = -0.24 años. Se calculó una edad máxima de 4 años. El coeficiente de variación del índice de desempeño de crecimiento (Ø′) para el método directo (CV = 5.26 %) mostró una variabilidad en el patrón de crecimiento según la región. La tasa de mortalidad natural (M = 1.36/año) fue alta, posiblemente por causa de depredación y enfermedades, entre otros. Las tasas de mortalidad por pesca (F = 1.95/año) y mortalidad total (Z = 3.31/año) fueron altas. La tasa de explotación (E = 0.59/año) indica que es probable que H. plumieri esté sobreexplotado.

Abstract:
The feeding habits of species of the genus Haemulon vary along their life cycle, therefore juveniles of H. aurolineatum, H. chrysargyreum, H. melanurun and H. striatum less than 80 mm total length are planctophagus and feed during light hours (except H. chrysargyreum which feeds at night). Juveniles of H. flavolineatum feed on planctonic and benthic invertebrates. In adults feeding changes to a diet of benthic organisms, more frequently decapod crustaceans, molluscs and polychaete worms in species such as H. aurolineatum, H. carbonarium, H. flavolineatum, H. melanurum, H. macrostomum, H. parrai, H. plumieri and H. sciurus. The change from planctonic to benthic feeding is slow and occurs in intermediate size fishes between juvenile and adult stages as it could be proved in H. aurolineatum and H. plumieri with sizes between 60-100 mm total length which diet was made of planctonic and benthic organisms. H. chrysargyreum, H. steindachneri, and H. striatum show mixed diets made of planctonic and benthic organisms. All species (excepts H. chrysargyreum) when adult feed at night. This has probably induced them to acquire behavior and coloration patterns different to those shown during daylight hours.
