Última Análisis espacio-temporal del estado nutricional de larvas de anchoíta Engraulis anchoita. Relación con las características hidrográficas y la disponibilidad de alimento OceanDocs Díaz, M.V.. Nutritional condition studies allow the assessment of physiological state of each larva and thus, the establishment of favourable nursery areas which provide better survival and growth. In the present work, morphometrical, histological and biochemical techniques were employed to assess nutritional condition of anchovy, Engraulis anchoita, larvae captured in the Argentine Sea. Its results were complemented with oceanographic data and information about zooplankton abundances, both prey and predators of anchovy larvae. Anchovy larvae abundance and distribution would be mainly determined by physico-chemical variables. Even though no significant differences were found in larval nutritional condition among the studied areas, larval condition was slightly better...

Período 2008-2011 OceanDocs Díaz, M.V.; Saia, J.; Soroet, S.; Pájaro, M.; Negri, R.M.. A study on the seasonal variation of Engraulis anchoita larvae nutritional condition was performed. The material employed was collected at the Estación Permanente de Estudios Ambientales (EPEA) during the 2008-2011 period (Buenos Aires prov., Argentina). In order to determine the morphological differences among individuals, the six morphometric variables measured for each larvae were analyzed using the Principal Component Analysis (PCA). Water temperature and salinity and density of the different ichthyoplankton components were also registered. The PCA revealed a larger larvae body width in Spring, which would indicate an improvement of nutritional condition during that season. Mean abundance of eggs and larvae, higher in spring, was significantly lower...

Ano: 2012 URL: http://hdl.handle.net/1834/4904 Estudio de la condición nutricional de larvas de la población bonaerense de anchoíta (Engraulis anchoita) en relación con las características hidrográficas del área de crianza OceanDocs Díaz, M.V.; Pájaro, M.. The study of larvae nutritional condition allows to assess the physiologic state that reflects the environmental situation they were exposed to. It represents a useful instrument to determine favourable nursery areas, provides tools for the management of a population subject to fishing and furnishes information to establish appropriate closed areas and periods. The material analyzed derived from three cruises carried out to assess Argentine anchovy Northern stock during the 2003, 2004 and 2006 reproductive peak (SW Atlantic Ocean, Argentine Sea). The objective of this work was to study the nutritional status of Argentine anchovy first feeding larvae caught in the coastal and mid-shelf of the Río de la Plata River maritime front in relation to the...
