Distribución de huevos, larvas y prerreclutas de merluza (Merluccius hubbsi) en la Zona Común de Pesca Argentino-Uruguaya. Período 1999-2001 OceanDocs
Machinandiarena, L.; Brown, D.R.; Ehrlich, M.D.; Pájaro, M.; Dorado, J.; Teso, V..
Distribution and abundance of eggs, larvae and prerecruit stages of Merluccius hubbsi were evaluated to examine spawning, nursery and settlement areas in the Argentine-Uruguayan Common Fishing Zone during the 1999-2001 period. Larvae and prerecruit stages were more abundant at stations from 50 m to 100 m depth. The nursery area would extend from the 50 m isobath south of 37° S to the 200 m isobath northward where the shelf becomes narrower. In the whole sampling area small size prerecruits were caught; therefore, the whole zone should be considered as a potential settlement area.

Elevage larvaire du Mulet lippu (Chelon labrosus) en conditions semi-extensives en mesocosme : croissance et developpement OceanDocs
El Abed, A.; Zouiten, D.; Missaoui, H.; Abdennadher, A.; Besbes, R.; Ben Khemis, I..
Dans le cadre du programme national de recherche intitulé Technologies d’élevage de nouvelles espèces marines à intérêt aquacole, un élevage larvaire de mulet lippu (Chelon labrosus) a été réalisé en conditions semi extensives en mésocosme. Ce travail présente les croissances linéaire et pondérale des larves âgées de 1 à 30 jours (J1-J30) ainsi que leurs caractéristiques (taux de croissances spécifiques, relations d’allométrie, ….). Il décrit aussi les principales étapes observées au cours du développement larvaire. Un échantillonnage de 15 larves a été effectué quotidiennement pendant les treize premiers jours puis tous les trois à quatre jours jusqu’à la fin de l’élevage. Les larves, préalablement fixées au glutharaldhéyde (solution à 2,5% dans du tampon...

Historia de vida temprana de la corvina rubia (Micropogonias furnieri, Sciaenidae) en el Estuario del Río de La Plata OceanDocs
Braverman, M..
This study encompasses the bio-physical interactions of whitemouth croaker (Micropogonias furnieri) early life stages living in La Plata estuary (Argentina-Uruguay, South America) to understand how they take advantage of the estuarine dynamics while traveling from spawning to nursery areas and undergoing ontogenetic and associated ecological changes. The analyses used include studies of spatio-temporal distribution length-dependent patterns; growth patterns looking for settlement marks in otoliths; and development related to metamorphosis and ontogenetic variations of the diet and trophic level. Samples and data come from vertically stratified samplings from 3 cruises (2005, 2006 and 2009). Distributional data also comes from an historic database. Results...

Microestructura de los otolitos Sagittae de larvas y juveniles de Merluccius hubbsi (Marini 1933): análisis comparativo entre las áreas de distribución bonaerense y norpatagónica OceanDocs
Buratti, C.C..
The life history of numerous aquatic organisms involves a pelagic larval stage, followed by a shift to a demersal or benthic existence (settlement) in the juvenile and adult stage. This transition and ecological, physiological and morphological changes frequently remain recorded like checks or marks in fish otoliths. As a contribution to the knowledge of hake (Merluccius hubbsi)life history, sagittae otoliths of larvae and juveniles with total length between 19 and 190 mm inhabiting North Patagonian and Bonaerensis waters in the Argentine sea (SW Atlantic)were analyzed. Using an image analysis system, otoliths microstructure was described and comparisons between left and right otoliths and between study areas in the following variables were realized:...

Modelling larval dispersal and settlement of the reef-building polychaete Sabellaria alveolata: Role of hydroclimatic processes on the sustainability of biogenic reefs ArchiMer
Ayata, Sakina-dorothee; Ellien, Celine; Dumas, Franck; Dubois, Stanislas; Thiebaut, Eric.
The honeycomb worm Sabellaria alveolata forms biogenic reefs which constitute diversity hotspots on tidal flats. The largest known reefs in Europe, located in the Bay of Mont-Saint-Michel (English Channel), are suffering increasing anthropogenic disturbances which raise the question of their sustainability. As the ability to recover depends partly on the recolonization of damaged reefs by larval supply, evaluating larval dispersal and the connectivity between distant reefs is a major challenge for their conservation. In the present study, we used a 3D biophysical model to simulate larval dispersal under realistic hydroclimatic conditions and estimate larval retention and exchanges among the two reefs of different sizes within the bay. The model takes into...
