| Over the last decades, the fishing effort focused on crustaceans and especially on the lobster has continued to increase. This way, the number of pots used by each boat has grown from a few dozen to several hundred. This process lead to an overexploitation of the seabed and the catches do not go over 400 tonnes/years despite the increase of the means involved. Consequently, it has been necessary to implement a number of new measures to protect the lobster stock, and some restricted areas have been created off the French coasts. |

| Artificial production from natural spawners could be a way of getting big quantities of spat of Pecten maximus, ln the method described, larval phase (until a size of 250 microns) occurs in a hatchery, post-Iarval phase (from 250 µ until 3 millimeters) in a nursery, and first growth period directly into the sea (from 2 mm to a size of 25-30 mm), The fifst results obtained, production of several thousand of individuals good enough for reseeding, seem to be transposable to a larger scale. |

| Among the different biological factors which can have an impact on the recruitment of the king scallop, the relationship between the number of produced oocytes and the number of obtained larvae can be tackled from an experimental point of view. In the framework of the repopulation program of the roadsted of Brest (king scallop pluri-annual program), the hatchery spat production trials (Buestel et al., 1982) enabled the monitoring of the variations of the real fertility of Pecten maximus over a year cycle. The natural egg-laying period in the roadsted of Brest spreads from June through to September, but egg-laying can also be triggered artificially all year long. The results obtained during production trials in 1982-1983 and the action of low temperatures... |

| The analysis of the Pecten maximus larval productions carried out between 1982 and 1986 in the framework of the repopulating program of the roadsted of Brest demonstrated the existence of a number of factors affecting larval growth in hatcheries: - Larval growth shows important seasonal fluctuations. It is minimal in February-March (3 to 4 µm.D-1) and maximal in June (6 to 8 µm.D-1). The growth of larvae from conditioned spawners does not differ from that of larvae from mature genitors collected in their natural habitat. Growth is favoured by an unknown factor present in sea water and held with a filtration of 0,2 µm. - The growth of the larvae cultivated in slack water in flat bottom ponds is higher than that of the larvae cultivated in bubbling water in... |

| Optimal gametogenesis and egg-laying environment, fertility, number of egg-layings, reproductor ageing, relationship between parent characteristics and conditioning and farming success, are the main issues considered by bivalve hatcheries each time the reproduction of a species is taken care of. Even if there is still very little bibliographic data on this precise field, reproduction mechanisms have been studied for decades in Mytilidae and Ostreidae. Largely cultivated in open sea, they are indeed an experimental material of choice. In this paper, we will see how the acquired knowledge and the methods developed on this material can be used to carry out a study on bivalve reproduction in hatcheries. |

| Les travaux commencés en 1973 avec la collaboration de Y. Koike sur la production artificielle d'Haliotis tuberculata devaient définir les aspects scientifiques et technologiques liés à l'obtention de juvéniles d'un an, non pas dans un but de repeuplement comme dans le contexte japonais, mais de promotion d'un élevage contrôlé en milieu naturel dans la zone de battement de marées. La volonté d'un contrôle systématique des élevages, d'une part, et l'utilisation éventuelle d'algues macrophytes, d'autre part, grâce aux immenses possibilités de production naturelle d'algues macrophytes dans la zone de battement des marées ont été les deux moteurs de l'orientation suivie dans le cadre de ce programme ormeaux. Les résultats obtenus depuis 1973 en laboratoire au... |

| 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 undertaken unless antibiotics are used. Experiments in the Caledonian Aquacultural Laboratory (LAC IFREMER Saint-Vincent) put across to the development of two antibiotic prophylaxis plans for substitution of erythromycine, one plan with oxytetracycline (hydrochloride), the other plan with trimethoprime-sulfadiazine association. After an antimicrobial agent susceptibility testing of bacteria and an acute toxicity study, efficacity assays are the biological validation of these projects of protocols |

| The reproduction effort in Crassostrea gigas, as in most bivalve molluscs, has priority over their somatic growth. At the beginning of spring, the energetic metabolic processes are geared towards gametogenesis over glucidic stocks, thus inducing a slowing down of the growth and a change in the organoleptic qualities of the flesh (Héral & Deslous-Paoli, 1983). The same authors showed that this effort increases along with age (figure 1). In young one-year-old oysters, the energy is mostly burnt in growth, only 18 % is involved in reproduction, whereas in two-year-old oysters, 60 to 65 % of the energy is used for gamete formation (Deslous-Paoli & Héral, 1983). In order to limit the impact of gonadogenesis and to try and re-orientate this energy flux... |

| La mission effectuée du 13 mai au 7 juin 90 à l'écloserie de la ferme Sodacal en Nouvelle-Calédonie avait pour but de tester les aqua-plakR pour les comptages bactériens en routine dans une écloserie industrielle. La technique classique (comptage sur boite de Pétri) est en effet très peu utilisée par les éleveurs du fait de sa lourdeur alors qu'une bonne connaissance de l'évolution de la flore bactérienne dans les bacs d'élevages peut s'avérer nécessaire pour assurer une gestion sanitaire correcte de ces élevages. D'autre part, une collection la plus large possible des différentes souches bactériennes rencontrées a été réalisée. Le présent rapport n'aborde que l'aspect utilisation des aqua-plakR, les souches bactériennes étant actuellement en cours... |

| La mission effectuée de mi-janvier à mi-février à l'écloserie CAMCAR (Colombie), avait pour objectif l'analyse quantitative et qualitative de la flore bactérienne présente en élevage larvaire de crevettes pénéides. L'intérêt principal du choix de ce site est de travailler dans une écloserie jeune (- de de deux ans) et n'ayant jamais rencontré de problème pathologique. Cette analyse fait donc le point sur les équilibres bactériens présents dans une écloserie industrielle saine mais bien évidemment dans un lieu et à une époque précise. |

| This study aimed to analyse the quality of the sea water flowing into the marine farm of Douhet, a gilthead bream hatchery, from the marsh-seawater reservoir to the entrance of the hatchery. The basin-seawater reservoir is not stratified in the pumping area. As a consequence, the measurements carried out at the surface to the right of the pumping dock give a good evaluation of the quality of the seawater pumped in depth. The high sensitivity of gilthead bream larvae to the water PH during the first two weeks of their larval life, and the values measured in the circuit seem to be an explanatory parameter to the observed mortalities. The water flowing into the hatchery retains, after pre-treatment, a nycthemeral PH variability, with maxima, at the end of the... |
