    Description: Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima legal de captura a partir de 2004. Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller Regional sobre la Evaluación y la Ordenación de la Langosta Común del Caribe en septiembre 2006 (Puga et al, 2006; FAO, 2007), donde se reconoció por la comunidad científica especializada que la pesquería de langosta cubana se encontraba bien manejada y plenamente explotada (no sobre- explotada) y se concluyó que además de la mortalidad por pesca, otros factores ajenos al sector pesquero estaban produciendo afectaciones en la abundancia del recurso, al causar daños al hábitat 1 en zonas de cría, influyendo negativamente por esta vía sobre el reclutamiento y la producción de langostas. Entre estos aspectos para Cuba se señalaron: la mayor frecuencia e intensidad de huracanes durante el último decenio, el desarrollo de las zonas costeras, la construcción de presas en las cuencas de captación de los ríos y de carreteras en el Archipiélago Sabana-Camagüey comunicando la isla principal con los cayos y los cayos entre si (pedraplenes).

    Description: El presente artículo da una descripción detallada de la elaboración y del "curado" de cuerdas de curricán, utilizadas anteriormente para la pesca en Taganga, un pueblo pescador en la costa norte de Colombia. Antes del "curado", estas cuerdas de fibras de algodón y de fabricación industrial, eran o destorcidas o torcidas a mano nuevamente, o tensionadas y envueltas con una cuerda más delgada del mismo material. El "curado" que siguió a estas operaciones se efectuó tanto en una cocción de corteza de las raíces zanconas de mangle, y/o por medio de un frote de estas cuerdas con los hypocotylos del mismo árbol (Rhizophora manglr). Por medio de las técnicas aquí descritas, los pescadores aspiraban a aumentar la resistencia de sus aparejos de pesca en el agua de mar.
    Description: The present paper gives a detailed description of the elaboration and curing of curricán Unes, formerly used as fishing lines in Taganga, a small fishing village on the northem coast of Colombia. These lines, made of cotton fibers and produced industrially, were disassembled and then retwisted by hand, or tightened and then carefully covered with a thinner string of the same material. The curing {"curado") that followed these operations was achieved by immersion of the lines into a boiled infusión of the bark of the prop roots of mangroves (Rhizophora mangle) and/or a rinsing with the hypocotyls of the same trees. By means of the techniques mentioned, the fishermen sought to improve the resistance of their fishing gear to sea water.

    Description: During a 3 week study, a total of 55 individuals of the redlip blenny (Ophioblennius atlanticus) were observed for at least two 15-minute periods, and several for ten of such periods. The sizes of their territories were estimated, the color pattern of each specimen an intra and interspecific interactions were recorded. The mean territory size of the redlip blenny in the study area appeared to be greater than that of these blennies studied in Curacao and Barbados by NURSALL (1977), the difference reflecting perhaps different methods of identifying the territories or a lower density of O. atlanticus in the Santa Marta área. Territories did not appear to be as consistently defended at the study area as at Barbados/Curacao and our impression ¡s that individuals holding large territories are less likely to defend their borders. It seems possible that light colored individuals are protected by their coloration from attack by dark colored territory owners. In territorial defense the redlip blennies grabbed each other tighthy by the mouth and struggled in this position repeatedly for about 15 seconds. Interspecific antagonism was common in the present study, the redlip blennics defended their territory frequently against Eupomacentrus dorsopunicans or E. partitus.
    Description: Durante un estudio de tres semanas, un total de 5 i individuos del bií'nido Ojih'toblcnnius atlnniicur. fueron observados por lo menos durante dos períodos de 1 í minutos para cada individuo y en algunos casos hasta por 10 de estos periodos. Se estimó el área de sus respectivos territorios y se tomó notí de los patrones de coloración de cada espécimen y de las relaciones intra e interespecificas de ellos. El tamaño promedio del territorio de estos blénidos resultó ser mayor que el de los respectivos territorios estudiados por NURSALL (1977) en Curacao y Barbados. Esta diferencia posiblemente se debe a un método diferente de definir los territorios o refleja una densidad menor de la población de O. aílanticus en Santa Marta, Los territorios del área fueron defendidos con menor intensidad a como lo fueron los de Barbados/ Curacao y es nuestra impresión que individuos ocupando un territorio extenso tienden a defender sus límites en menor grado. El color claro de algunos individuos probablemente los protege de agresiones por parte de individuos de color oscuro. En el acto de defensa territorial intraespecífica, los blénidos se agarran por sus bocas y se sacuden mutuamente durante aproximadamente 15 segundos , pudiéndose repetir esti varias veces. Con frecuencia se observarondefensas de los territorios dirigidas hacia los peces doncella Eupomacentrus dorsopunicnas y E. partitus.

    Description: Se ha estudiado la variación anual de la condición de la lisa Mugil incilis Hancock en la Ciénaga Grande de Santa Marta (CGSM), la mayor laguna costera del Caribe Colombiano, haciendo énfasis en la influencia ejercida por factores ambientales como la salinidad, la temperatura y la transparencia de las aguas sobre la condición de esta especie de Mugilidae. Las diferencias estacionales observadas en la condición de M. incilis están evidentemente relacionadas con su desarrollo gonadal y dependen de la disponibilidad de alimento. La dieta de M. incilis se basa en detritos y su suministro de alimento parece ser muy afectado por el aporte fluvial a la CGSM, el cual es también responsable de los cambios en la salinidad de la laguna, esto explica la relación inversa (r = -0.82) hallada entre la salinidad y la condición de M. incilis expresada por C = 0.9949 - 0.0057 S(°/oo). La variación anual de la salinidad sigue un patrón rítmico de cambios estacionales, no precisamente "in situ", sino en regiones continentales distantes: las cabeceras de los tributarios de la CGSM. Estas lisas desovan en aguas del Caribe adyacente a la CGSM y su período de migración (dic-marzo) comienza con su mejor condición física, y retornan a sus áreas de alimentación en la CGSM 2 a 4 semanas después, hasta el final de la migración, con su condición mínima ya que al parecer estas lisas no se alimentan durante su migración de desove. No se observaron cambios relacionados con las variaciones de la temperatura. Las aguas más turbias coincidieron con los sitios de alimentación de M. incilis.
    Description: The annual variation in condition of the mullet Mugil incilis Hancock has been studied in the Ciénaga Grande de Santa Marta (CGSM). The largest coastal lagoon on the Colombian Caribbean, with emphasis on the influence of such environmental factors as salinity, temperature and transparence of the waters on the condition of this species of Mugilidae. Seasonal differences observed in condition of M. incilis are evidently related to gonadal development and depend on food availability. The diet of M, incilis is based on detritus and its food supply seems to be very influenced by river discharge which also accounts for the salinity changes in the lagoon. this explains the in verse correlation (r = -0.82) found between salinity and condition of the mullets expressed as C = 0.9949 - 0.0057 S (°/oo). Annual salinity variation follows a rhythmic pattern of seasonal changes. not precisely "in situ", but in distant continental regions: the headwaters of the tributarles of the CGSM. These mullets spawn in Caribbean waters adjacent to the CGSM and their migración period (Dec-March) begins with their best physical condición, returning to their feeding áreas in the CGSM 2 or 4 weeks lacer, until the end of the migración, with their lowest condition since these mullets apparently do not feed at all during the spawning migration. No change related to temperature variations was observed. and turbid waters were the rule in M. incilis feeding sites.

    Description: En Afrique de l'Ouest, la zone littorale et ses ressources représentent une composante essentielle pour le développement. Près de 60% de la population est concentrée à moins de 20 km des côtes . La part des ressources halieutiques dans l'alimentation des populations est très importante et croissante. Au Sénégal par exemple, elles contribuent jusqu'à 70% des apports en protéines. A cela s'ajoute le poids socio-économique très important de la pêche en général et de la pêche artisanale en particulier devenue l'un des secteurs les plus stratégiques pour l'économie nationale en Mauritanie notamment. Le Cadre Stratégique de Lutte contre la Pauvreté du Gouvernement Mauritanien considère que : "compte tenu des possibilités qu'elle offre en terme de création d'emplois et de sécurité alimentaire notamment pour les populations pauvres, mais également de génération de recettes en devises, la pêche artisanale revêt une grande priorité, un plan décennal de développement lui sera consacré ".

    Description: Regarding the importance of increment of fish per capita consumption in the health of the society, it is important to understand the benefits of fish and its nutritional value to prevent and treat some diseases. The research aimed to investigate the awareness of fisheries students about the benefits and fish nutritional value to promote the fish consumption in their household and future occupational in society. Students' information questionnaire of two universities on the content of lipids and proteins, vitamins, minerals, amino acids, fatty acids, reasons for fish consumption and their therapeutic effects were collected in 2017. After analyzing Chi-squared and Friedman test and scoring the correct answers, 64.4% of the students did not affect the consumption of their household fish consumption after their acceptance. Fish per capita consumption of students was calculated to be 23.3 kilograms. In their view, Iodine is the richest element in fish to prevent goiter. Cardiovascular disease, Alzheimer and cancer are prevented using fish consumption. With a mean score of 7.53 and a score of 18 at most, 16.4 % of students had awareness of the benefits of fish. The result of the study revealed the need for more serious training and more attention to the fish benefits and nutritional value of the fisheries course curriculum, so that they can be better promoters for the fish consumption among people and their families.

    Description: Our paper presents the results of a study on the concentrations of total (Hgtotal), organic (CH3Hg+) and inorganic (Hginorg) mercury in freshwater fish from the Vistula Lagoon, coastal waters of the Baltic Sea. Mercury assays were performed on tissues (muscle, skin, gills) and internal organs (heart, spleen, liver, gastrointestinal tract, gonads) of pikeperch, common roach, and common bream. The distributions of Hgtotal, CH3Hg+, and Hginorg depending on fish species, tissue, or organ and bioaccumulation in tissues and biomagnification in the trophic chain were determined. Interspecific and intraspecific differences in mercury concentrations occurred in fish tissues and organs. Muscles of pikeperch, bream and roach accumulated the highest concentration of CH3Hg+, Hginorg dominating in the gastrointestinal tract of bream and roach. The concentration gradations of Hgtotal and CH3Hg+ depending on fish species were as follows: pikeperch 〉 common roach 〉 common bream. For Hginorg, the gradations were as follows: common bream 〉 common roach 〉 pikeperch. The type of food was a determining criterion for the distribution of mercury forms in the tissues and organs of the fish studied, and quantifiable confirmation of this was the different values of the L:M coefficient (Hginorg in the hepatic tissue : CH3Hg+ in muscle). Differences in Hgtotal, CH3Hg+, and Hginorg concentrations in fish tissues and organs were linked with the food the fish consume, their position in the trophic chain and biomagnification in the food chain.
