| En este estudio se presenta el análisis de la relación entre los valores de densidad de hembras maduras y de hembras impregnadas de langostino Pleoticus muelleri (Bate, 1888) del Golfo San Jorge y las variables ambientales. Los datos analizados provienen de las campañas de investigación del INIDEP OB-03/08 y OB-01/09 realizadas en noviembre-diciembre de 2008 y en enero-febrero de 2009, respectivamente; en el área comprendida entre las latitudes 43º 20´ S y 47º 00´ S y el meridiano 64º 00´ W y la costa. Se consideraron las variables biológicas: densidad de hembras maduras y de hembras impregnadas de langostino, por rango de tallas y las variables ambientales: profundidad, temperatura y salinidad de agua de fondo así como, la diferencia de temperatura y de... |

| Se estudia la biología y ecología reproductiva de las ocho especies de Bathyraja presentes en la plataforma continental argentina (Atlántico S.O.), a través del análisis del tamaño corporal, las cápsulas de huevos, el desarrollo de los embriones, la talla de madurez sexual, las variaciones en las condiciones reproductivas, las áreas de puesta y la segregación espacial de los individuos. El material examinado provino de campañas de investigación llevadas a cabo por el Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) entre 34º40'S y 54º30'S, desde septiembre 2003 hasta octubre 2007. La información presentada en el trabajo demuestra que las especies del Género Bathyraja en la plataforma argentina maduran a una talla alta en relación a la Lt... |

| Fish habitats sustain essential functions for fish to complete their life cycle, such as feeding, growing and spawning. Conservation is crucial to maintain fish populations and their exploitation. Since 2013, the spawning stock biomass of the northern stock of European seabass (Dicentrarchus labrax) has been in a worrying state. A series of low recruitments with a persistently high level of fishing has been blamed, raising concerns about the processes involved in seabass reproduction and settlement in nurseries. Here, we characterise seabass spawning areas along the French Atlantic coast using vessel monitoring system (VMS) data. A non‐linear geostatistical approach was applied, from 2008 to 2014, to detect locations where seabass aggregate for spawning.... |

| As an initial step in establishing mechanistic relationships between environmental variability and recruitment in Atlantic cod Gadhus morhua along the coast of the western Gulf of Maine, we assessed transport success of larvae from major spawning grounds to nursery areas with particle tracking using the unstructured grid model FVCOM (finite volume coastal ocean model). In coastal areas, dispersal of early planktonic life stages of fish and invertebrate species is highly dependent on the regional dynamics and its variability, which has to be captured by our models. With state-of-the-art forcing for the year 1995, we evaluate the sensitivity of particle dispersal to the timing and location of spawning, the spatial and temporal resolution of the model, and... |
