En el presente estudio se estimó el periodo de reproducción a través de los índices gonadosomático (IGS), hepatosomático (IHS) y el factor de condición de B. panamensis. Las muestras fueron obtenidas mensualmente entre noviembre de 2015 y octubre de 2016 de la pesca comercial del área de San Blas. Se recolectaron 346 ejemplares de los cuales 182 fueron hembras y 164 machos. Las tallas (longitud total y peso) encontradas no mostraron diferencias entre sexos. La proporción sexual no fue diferente de 1:1 para el total de las muestras. La relación peso-longitud mostró que ambos sexos presentaron un tipo de crecimiento alométrico positivo. De acuerdo al índice gonadosomático (IGS) y el hepatosomático (IHS) se observó que esta especie presenta un periodo de reproducción al año, que va de mayo a agosto. Con base en estos resultados, se podría proponer una estrategia de manejo para esta pesquería en el sureste del Golfo de California.","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120891672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four seasonal surveys (summer, autumn, winter and spring) were performed in the middle and lower intertidal levels at seven sampling stations established on both sides of an urban sewage discharge point, and water and sediment variables were measured. To explore possible spatial variations in the community, environmental and biological data were analyzed using univariate and multivariate statistics. Community composition varied with intertidal level, sediment characteristics and distance to sewage discharge site. In sediment with high mud content, the community was characterized by Darina solenoides, Mysella patagona , Eteone sculpta, Scolecolepides uncinatus and Capitella sp., in the middle intertidal, and was characterized by M. patagona and Ampelisca sp. in the lower intertidal. In sediment with dominance of fine sand, the community was characterized by Aricidea sp. at both intertidal levels. Near the effluent discharge site, the community was largely dominated by M. patagona . Intertidal level and sediment particle size are the main factors determining the composition of benthic assemblages in the study area. Sewage discharge also affects the composition of the infaunal community, possibly as a result of the contribution of particulate organic matter in suspension that stimulates the populations of detritus feeders.","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130313915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stocking density effect was studied on growth and survival of juveniles II from 30 days to commercial size in net cages. Survival of the juvenile I was not affected by stocking densities from 2 to 5 ind L -1 and was greater than 70% in all treatments. Seahorse length, however, was inversely related to stocking density. Both treatments with wild zooplankton promoted higher seahorse survival and growth than diet composed exclusively by Artemia sp. during the first 15 days of life. Juvenile II growth decreased with stocking density from 5 to 40 ind m -3 but survival was not affected by it. The total benefit and proportion of colored animals increased significantly with stocking density. The present study confirms the technical feasibility of organic multi-trophic seahorse production in net cages. Even at the highest density tested the seahorses grew well and could generate high profits.","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130722589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current treatment for tuberculosis is a combination of antituberculosis drugs for at least 9 months. Nowadays, the search for new pharmacological agents for the treatment of tuberculosis is an urgent endeavor. Microalgae produce a wide variety of molecules that possess biological activities of pharmaceutical interest. Therefore, the objective of this work was to evaluate the antimycobacterial activity of hexane crude extracts of 6 microalgae: Chlamydomonas mexicana , Porphyridium cruentum , Isochrysis galbana , Rhodomonas sp., Aphanocapsa marina, and Nitzschia palea . All of the hexane extracts inhibited at least 90% of the growth of Mycobacterium tuberculosis H37Rv at a concentration of 100 μg ml -1 . The hexane crude extract of I. galbana had the highest antimycobacterial activity displaying a percentage inhibition that was equal to that of the antituberculosis drug isoniazid and having a minimum inhibitory concentration of 50 μg ml -1 . These findings demonstrate that microalgae are an excellent source for the search of novel antimycobacterial compounds.","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124697698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Species were studied in batch cultures, at the beginning of stationary growth phase with different irradiance and 2 levels of nitrogen content for Chaetoceros sp., and constant irradiance with 5 concentrations of sodium nitrate for I. galbana in an F/2 medium. Isochrysis galbana produced higher levels of linolenic acid and docosahexaenoic acid than eicosapentaenoic acid (EPA) at low N-nitrate concentrations; however, fatty acids increased notably with surplus N-nitrate, above F/2 medium content. Low irradiance and normal concentration of nitrates in the batches of Chaetoceros gracilis species produced a greater EPA content.

El objetivo del trabajo fue describir las características reproductivas de E. labriformis. Se realizaron muestreos mensuales entre 1998 y 2008 utilizando redes agalleras. De cada organismo se obtuvo la longitud total (LT) y el peso total (PT); las gónadas fueron extraídas, pesadas, clasificadas según el estadio de desarrollo y preservadas para análisis histológicos. Se recolectaron 940 ejemplares, 521 fueron hembras y 419 machos. La longitud promedio de las hembras fue de 30,1 (± 0,14) cm y la de los machos 31,3 (± 0,13) cm LT. Los máximos valores del índice gonadosomático y los mayores porcentajes de gónadas maduras tanto en hembras como en machos, se presentaron en abril y agosto. El factor de condición presentó escasa variación temporal. Mediante el análisis histológico de las gónadas se identificaron ejemplares en transición, con ovarios con ovocitos en regresión y tejido testicular en desarrollo. El desarrollo de los ovocitos es asincrónico y el del testículo es de tipo lobular. El ejemplar más pequeño encontrado en transición midió 25,6 cm LT. La longitud promedio de maduración sexual fue 29,6 cm LT para hembras y 31,3 cm LT para machos; contrastando estas tallas con las de captura, se infiere que los individuos capturados habrían tenido al menos un evento reproductivo.
