Maturation and spawning in captivity of penaeid shrimps

As no indigenous species of commercial penaeid shrimp live in the waters of French Po1ynesia, the pre1iminary step in deve10ping shrimp aquaculture was to obtain maturation and spawning in captivity. Five species have been investigated. Wi1d-caught j...

Three years of experimental and applied research on the use of dietary probiotic Pediococcus acidilactici in shrimp culture : overview of the main res...

In recent years the biological control of diseases by environmental friendly methods such as probiotics has become an important subject of investigation in aquaculture research. Probiotics are live microorganisms which when administrated in adequate ...

Reproduction of the hawaiian strain of pacific blue shrimp Litopenaeus stylirostris in New Caledonia.

The Pacific blue shrimp Litopenaeus stylirostris was introduced in New Caledonia thirty years ago. Because of its high inbreeding, a SPF strain domesticated in Hawaii, genetically differentiated from the Caledonian strain, had to be imported. The two...

L'élevage larvaire de crevettes en Nouvelle-Calédonie. L'Oxytétracycline et l'association Triméthoprime - Sulfadiazine en tant qu'alternatives à ...

Aquaculture of penaeid shrimps holds a major place in productions of animals. New Caledonia takes part to these productions by developing the breeding of Pacific blue shrimp Litopenaeus stylirostris. Nowadays, penaeid larviculture can’t be undertak...

Contrat de Plan Etat Région Poitou-Charentes 1994-1998. Convention 96 RPC R70 - Programme Pathologie - Rapport Scientifique année 1996

Le but de ce programme pathologie est de rechercher et d'étudier les agents pathogènes connus et inconnus chez les mollusques bivalves marins, plus particulièrement chez l'huître creuse, Crassostrea gigas, afin d'identifier d'éventuels agents ca...

Effluents from land based marine farms: nature, treatment, valorisation, modelisation. Applications to fish and shrimp rearing

Fish culture (seabass, turbot...) on the French metropolitan coast, and shrimp culture in the overseas territories (essentially New Caledonia and Tahiti) are subject to a regular development through land based farms. Three thematic of research on aqu...

A Red Shrimp, Farfantepenaeus brasiliensis (Latreille, 1817), Larvae Feeding Regime Based on Live Food

Red shrimp, Farfantepenaeus brasiliensis, larvae's response to different concentrations of live foods (diatoms Chaetoceros gracilis: 20-100 x 103 cells/mL; flagellate Tetraselmis chuii: 2-10 x 103 cells/mL and Artemia nauplii [NA]: 1-5 NA/mL) was inv...

The impact of easily oxidized material (EOM) on the meiobenthos: Foraminifera abnormalities in shrimp ponds of New Caledonia; implications for environ...

This study was carried out in shrimp ponds from New Caledonia, in order to determine the cause of the exceptional proportion of abnormal tests (FAI) (often >50%, sometimes >80%). FAI was positively correlated to the quantity of easily oxidized materi...

Recent innovations in cultivation of molluscs in french Polynesia

Until recently, mollusc production in French Polynesia was only based upon fishing, for local consumption of edible bivalves mainly the oyster Saccostrea cucullata and for the exportation of pearl-oyster shells. As a consequence of parasitism problem...

Floating cages as an experimental tool for shrimp culture studies: first attempts to check their reliability

The first aim of this study was to evaluate on a technical basis the rearing of shrimps in floating cages set up in earthen ponds. Shrimps reared in and outside the cages presented comparable growths and survival rates. Then it was concluded that shr...
