Larval rearing and weaning of seabass, Lates calcarifer (Block), on experimental compounded diets
Provedor de dados: 5
Autores: Fuchs, Jacques; Nedelec, Georges.
Larval rearing trials of seabass larvae, either imported from Singapore or obtained from the captive broodstock of IFREMER/C.O.P. at Tahiti, were carried out since 1987, by testing different technologies originally used in South East Asia (green-water culture, sequential water changes) or developed by IFREMER for other species (clear water system, preys enrichment, continuous water renewal).

L'élevage du Loup tropical (Lates calcarifer, Bloch) en Polynésie Française. Approche technico-économique
Provedor de dados: 5
Autores: Pierson, R; Thouard, Emmanuel; Nedelec, Georges.
Due to lack of knowledge about the seabass (Lates calcarifer) market in Polynesia, various production levels were considered to develop a managing tool for decision, making relevant development strategy and adapted rearing technology. This work is an analysis of the economical parameters of known rearing techniques depending on various production levels.  The comparative study of the techniques, phase by phase, regarding the production cost and the investments prompted us to select the semi-intensive larval rearing technology under the current economical conditions. However, the larval rearing extensive technique could be of highest interest for productions lower than 60 metric tons a year. Growing-out in floating net-cages appeared to be the only...

Génotypage des géniteurs de Lates calcarifer de Tahiti : aide à la domestication raisonnée du Loup Tropical pour la filière tahitienne
Provedor de dados: 5
Autores: Vonau, Vincent; Rouxel, Catherine; Saulnier, Denis; Cochennec-laureau, Nathalie; Nedelec, Georges; Goyard, Emmanuel.
The tropical seabass Lates calcarifer was introduced in Tahiti in 1984 and then was domesticated without other introduction. Three successive generations have been obtained in captivity. Tissue samples of the 38 animaIs which represent the total Tahitian broodstock were preserved in alcohol to be genotyped with four microsatellite markers (Yue et al., 2001). Three of four described markers were successfully transferred to the laboratory of genetics of Tahiti (marker LcaM01, LcaM02, LcaM03), as the revelation technology available locally did not allow the use of LcaM04 in routine. The results show that the genetic diversity of the tahitian broodstock is not equivalent of the one of the species, which could be explained by the small size of the founder...

L'élevage du Loup tropical (Lates calcarifer, Bloch) en Polynésie Française. Techniques d'élevage - Synthèse de neuf années de recherche
Provedor de dados: 5
Autores: Thouard, Emmanuel; Nedelec, Georges; Pierson, R.
Lates calcarifer, a species originated from Southeast Asia and Australia. Was selected among several tropical finfish species because its particular ability for aquaculture. Nine years of research led to a rearing technology adapted to the environmental and socio-economical conditions of French Polynesia. This report is a synthesis of the works that resulted in the control of the whole rearing cycle.  A captive broodstock was necessary when using such an introduced species. This fish, a protandrous hermaphrodite, presents a spawning seasonality. A broodstock conditionning facility was designed to get mature spawners throughout the year. Environmental manipulations associated with a hormonal induction method guaranteed egg production aIl over the year....

Selection of finfish species (seabass) as candidates for aquaculture in French Polynesia
Provedor de dados: 5
Autores: Fuchs, Jacques; Gasset, Eric; Nedelec, Georges.
Species with a very high potential for aquaculture, allowing development projects on a short terms basis: the seabass originating from S.E. Asia. Species, potentially interesting but presenting some drawbacks, as difficulties to perform larval rearing or presenting pathological problem. Species considered as difficult to rear and not retained like Siganus argenteus , Siganidae or Caranx ignobilis , Carangidae. The future development of finfish in Polynesia is emphasized and a project of sea bass netcage culture in Polynesian lagoon is presented.

Ce rapport constitue l’aboutissement en fin d’année 2005 de la deuxième phase du Contrat de développement sur la maîtrise de l’élevage de poissons lagonaires, programme réalisé à l’Ifremer de Vairao en collaboration étroite entre l’Ifremer et la Polynésie française, et conduit par le service de la pêche (SPE) de Polynésie française. L’année 2005 a été consacrée essentiellement à la poursuite de nos travaux de mise au point technique de l’élevage du « Moi » et du « Paraha peue ». Dans ce cadre, rappelons qu’en début d’année 2005, un bilan de nos travaux ainsi qu’un recadrage des objectifs et des actions ont été réalisés lors d’une réunion technique de concertation à laquelle participait notamment Denis Coves, responsable des programmes piscicoles à...
