Movement activity and localization of food were studied dynamically with the objective of establishing the capacities of behavioral adaptation of the young Dicentrarchus labrax faced with a novel situation. The role played by previous rearing conditions was demonstrated, the level of stimulation being a sensitive intervening factor (currents associated with the food). The data show the favourable effects of such treatment, and are in agreement with work carried out on higher vertebrates, which have brought to light the importance of early stimulation in behavioral ontogeny which respect to emotionality as well as capacities of adaptation in subjects reaching adulthood. |

L’engraissement du thon rouge a connu un regain d’intérêt depuis le boom économique japonais i.e. vers le milieu des années 70. A cette époque les projections ont mis en évidence que la production mondiale ne suffirait plus à satisfaire le marché japonais. C’est ce constat qui a amené les grandes firmes japonaises à réfléchir sur l’engraissement du thon rouge. Cette technologie fût exportée en Espagne où l’activité a démarré effectivement au début des années 1990 pour atteindre son apogée vers les années 1996-1997. Plusieurs pays méditerranéens ont suivi le pas de l’Espagne à l’image de la Croatie, Malte, Chypre, Italie, etc., En Tunisie, pendant les six dernières années (2003-2008) l’activité d’engraissement du thon rouge (BFT) a atteint voire dépassé... |

Un échantillonnage de poissons parasités (Diplodus puntazzo) en provenance d’une firme aquacole située au Sud-est de la Corse (Ouest méditerranéen) montre une infestation due à un Myxidium leei. Le parasite envahit l’épithélium intestinal causant amaigrissement du poisson et une forte mortalité. Les spécimens de plus de 16 cm de longueur totale étaient significativement moins infestés. Toutefois, l’infestation ne montre pas de différence significative entre mâles et femelles quelle que soit la taille des spécimens. Quelques paramètres hématologiques ont été utilisés pour montrer le rôle du parasite dans cette maladie de poissons et statuer sur l’interaction hôte-parasite. |

The brine shrimp <i>Artemia</i> , an excellent live food source in aquaculture, has been studied as a carrier to deliver selected chemotherapeutic agents to fish for prophylactic treatment of infectious diseases. To monitor the efficiency of incorporation of trimethoprim and sulfamethoxazole in <i><i>Artemia</i> franciscana</i>, a sensitive and specific analytical method was developed. It is based on homogenization of <i>Artemia</i> nauplii in methanol, extraction of lipids with hexane, solid-phase cleanup on C<sub>18</sub> cartridges, and reversed-phase liquid chromatography with detection at 210 nm. The method is sensitive (detection limit, on the order of 3 µg/g with a sample quantity of 30 mg... |

Recientes problemas provocados por epiemias de infecciones de Ichthyophthirius multifiliie en la cría de bagre negro (Rhandia sapo) cultivado por el Departamento de Acuicultura del INAPE de Uruguay, y el conocimiento de que todos los piscicultores tienen problemas con los parásitos, constituyeron la base y antecedente para el inicio de un programa de investigaciones parasitológicas. Este programa incluyó. 1) Disección de bagres capturados en Laguna de Sauce y colecta de parásitos. 2) Disección de bagres cultivados en el Laboratorio y en los estanques de INAPE, y colecta de parásitos. 3) Identificación de los parásitos recolectados. 4) Elaboración de un manual que recopila los métodos más comunmente utilizados en parasitología e histopatología en la... |

Marine capture fisheries in Jamaica is primarily artisanal in nature ansd is conducted maiinly by fishermen operating from canoes. Approximately 95% of these fishermen operate on the coastal shelf and its associated banks. The commercial species harvested comprise bottom-dwelling, coral reef species and free swimming species of finfish. Other fishery resources of commercial value include marine shrimp, conch and lobsters. Catch statistics are not available for all species, but the Department of Fisheries reports a slight decline in fishery production with production decreasing from 16 milion lbs in 1990, despite the fact that fishing efforts have doubled. Over this period the number of registered fishermen has grown from 12 000 to 16 000, al of whom are... |

Circannual, diel, and lunal periodic mechanisms in naturally reproducing stocks of tropical and subtropical fishes are reviewed. Manipulations of biological clocks, used to control reproduction in captive broodstocks, are detailed. Experiments to induce controlled maturation and spawning in fishes either test efficacy of changing environmental conditions (regimes), or constant environmental conditions (controlled). Data have been generated in experimental/scientific studies, as well as applied research. Effects of controlled environmental regimes on serum steroids, gametogenesis, spawning, fry performance and egg quality are summarized for selected members of Centropomidae, Serranidae, and Sciaenidae. |

The appearance, ossification and growth of cartilaginous structures of the mouth in early larval stages of laboratory reared red porgy Pagrus pagrus, were examined. At the time of mouth opening, red porgy larvae are equipped with the fundamental components of the oral cavity to allow the sucking motion for acquiring food. During the initial feeding stage, from day 5 after hatching (AH) to day 7 AH, the hyoid and lower branchial archs were completed, and the head length and other structural elements, like the ceratohyal-epihyal cartilage, increased rapidly. These events intensified sucking mechanisms by increasing the amount of ingested rotifers. After day 13 AH, the presence of the bony premaxilla and angular, the ossification of the Meckels cartilage and... |

O aumento mundial da contaminação de sistemas de água doce com inúmeros compostos químicos industriais e naturais é hoje um dos principais problemas ambientais.Mineração, emissão de esgoto doméstico, aplicação de fertilizantes e pesticidas degradam severamente os ecossistemas aquáticos com metais pesados. A aquicultura, caracterizada nas últimas décadas como potencial atividade agropecuária não está isenta desta negativa contribuição, uma vez que utiliza, em sua cadeia produtiva, compostos que interferem diretamente na cadeia trófica dos sistemas aquícolas. Dentre os principais produtos utilizados na piscicultura, para contornar as dificuldades no processo produtivo, pode-se citar o sulfato de cobre (CuSO4) que, quando utilizado indevidamente, gera efeitos... |
