Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ). |

A condition in Sparus aurata larvae termed "distended gut syndrome" (DGS) has become a major problem in the past three seasons. Unable to digest rotifers and brine shrimp nauplii, the larvae develop a swollen abdomen, exhibit a disoriented spinning motion and are swept passively with the current. Bacterial or viral infections were suspected. Chloramphenicol-supplemented larval food did not affect the prevalence of DGS. Virus-like particles 80 nm in diameter were observed in necrotic cytoplasm of midgut wall cells. |

The foreign artisanal fishery of Pointe-Noire (Congo) significantly evolved since its beginning, in the 1950s, by the number of fishermen and canoes, as well as the fishing techniques used and by its socio-economic organization. The fishery for Sardinella by surface gill-nets, its main activity, is based on common ownership and savings, thus allowing partial reinvestment of fishing revenues, the riskier (such as bottom gill-net) being left to individual initiatives. The foreign fishery employs many Congolese fishermen, in a permanent or very occasional way. However no improvement effect seems to have taken place in favor of the local artisanal fishery. |

The authors present the necessary to sort catfish and sea bream fries in order to limit cannibalism, to constitute homogeneous groups. In the same time they studied different sorters (bars sorter, grating sorter and the conception of an experimental sorter) and their effects on the juveniles (behaviour). Introduction: In hatchery, early sorting of Sea Bass or Sea Bream fry after weaning can become necessary for several reasons: a) To obtain homogeneous batches thus simplifying growing management by better controlling: - Specific water flow for precise ranges of size or weight, - Food distribution granularity, - Daily feeding rate. b) To limit cannibalism which can become high when population dispersion is spread out. This dispersion greatly increases... |

Introduction: To develop its 2005-2009 strategic plan, IFREMER made two prospective analysis studies in 2003: a thematic prospective analysis and a sectorial prospective analysis. The "aquafarming" sectorial prospective analysis, based primarily on an IFREMER idea, particularly brought to light the difference in nature of problems posed by the future evolution of shellfish farming, fish farming and other stockbreeding (pearl farming and shrimp farming). In addition, the prospective analyses made on an international scale by the FAO (2002, 2004) and the IFPRI (2003) emphasise that the development of aqua farming is the required condition for satisfying world demand of consumer aquatic products, given the foreseeable weak growth, indeed, the stagnation of... |

The present work analyses and describes Merluccius merluccius ovarian cycle in the Bay of Biscay as an example of partial spawner. Three methods were employed: a macroscopic examination of about 10,000 ovaries -- a cytologic and histologic study -- an investigation of the size structure of the oocytes population of 63 ovaries. The author developed an original mathematical method for serial spawning demonstration. He demonstrates that hake is a partial spawner: a female usually rapidly spawns 4 or 5 times without ovaries rest. On this basis, he gives a new reference scale of the maturity stages of the ovarian cycle: after developing (II), ripe (III), running (IV), the partly spent ovary is named (II+); the repetitive sequence III-IV-II + characterize serial... |
