Analysis of shell colour determinism in the Manila clam Ruditapes philippinarum ArchiMer
Peignon, Jean-marie; Gerard, Andre; Naciri, Yamama; Ledu, Christophe; Phelipot, Pascal.
The Manila clam presents a large polymorphism for shell colours and patterns. No experiment has been conducted to study the determinism of such a polymorphism which has been well known for a long time. The aim of this study was firstly to determine the genetic variation for shell colour and secondly to produce some homozygous lines for the shell colouring. These lines could then be used as controls for laboratory experiments. The colouring is defined by three characters: asymmetry, ornamentation and hue. Clams with asymmetrical colouring are not fully pigmented, except for a posterior band on the left valve. Clams with symmetrical colouring are fully pigmented on the two valves. Four cross series were conducted between the different characters: Asymmetry...

Bilan des perturbations phytoplanctoniques observées sur les côtes françaises en 1986 ArchiMer
Belin, Catherine; Berthome, Jean-paul.
In 1986, 23 discolored waters were observed ; dinoflagellates often were the cause of them. Many developments of Prorocentrum minimum occured ; two of them were associated with shel1fishes mortalities. At contrary, other species which are suspected to be toxic for shellfishes, as Gyrodinium aureolum and Gyrodinium spirale, have not been associated with mortalities, although they have been observed in several areas. The developments of Dinophysis (cf. acuminata or sacculus) caused provisional prohibitions of shellfishes selling, especially in the south of Brittany. Another specie was also implicated in toxicities : Prorocentrum lima. Human intoxications and economic consequences were rather important.

Contribution à l'étude du système neuroendocrine de la moule Mytilus edulis (Mollusca: Bivalvia) ArchiMer
Kellner-cousin, Kristell.
Dans le cadre de ce travail, l'étude du système neuroendocrine de la moule Mytilus edulis a été envisagée sous plusieurs aspects qui définissent les quatre grandes parties de la thèse. Dans une première partie est décrit le travail de préparation et de caractérisation d'anticorps monoclonaux (AcMc) spécifiques de ganglions cérébroïdes (GC) de Mytilus edulis. Le développement de techniques de préparation d'AcMc dirigés contre des antigènes non purifiés a en effet permis de produire un ensemble de réactifs de type AcMc dirigés contre différents antigènes issus d'un broyat de GC de moule. La spécificité de ces AcMc a été étudiée en microscopie optique puis électronique selon des techniques immunocytochimiques (immunopéroxydase indirecte et immunogold). La...

Croissance et mortalite du petoncle noir Chlamys varia dans le bassin d'Arcachon, France ArchiMer
Trut, Gilles; Robert, Rene; Laborde, Jean-louis.
Until 1960, the Black scallop Chlamys varia was relatively abundant along the French Atlantic coasts. Today most of these natural beds have disappeared. Because mollusc hatchery and nursery techniques have been mastered, the reintroduction of this species, under control, was carried out in several areas and particularly in the bay of Arcachon, from 1989 to 1992. Good results were obtained in hatchery and nursery but the development of the juveniles in the natural fields was poor. The growth of Chlamys varia was satisfactory but heavy mortalities were rapidly recorded which could not be related to the hydrobiological conditions. This species seems to be very sensitive to short emersion and removal operations which are incompatible with aquaculture processes.

Etude cytologique de la gamétogenèse, de la sex-ratio et du cycle de reproduction chez l'huître perlière Pinctada margaritifera (L) var. cumingii (Jameson), (mollusques, bivalves). Comparaison avec le cycle de Pinctada maculata (Gould) ArchiMer
Thielley, Maryse.
The population of Pinctada margaritifera and Pinctada maculata lay eggs throughout the year. Temperature variations induce huge but asynchronous laying. Preferential periods of gonad maturity correspond to the season changings in both species. However. some differences between the two specics are noticed. Both species are protandric hermaphrodites. Female condition is unstable: a reversion to the male condition may be observed and is probably linked with stress. The average size for the first sexual maturation as weil as for sexual conversion are specified in P. margaritifera. The breeding conditions induce modifications in some reproductive cycle processes (maturation, sex-ratio). Some conditions suitable for reproduction may become unfavorable to...

Etude de la réponse immunitaire chez l'huître Crassostrea gigas : caractérisation et fonctions de protéines de reconnaissance aux LPS et d'effecteurs antimicrobiens ArchiMer
Gonzalez, Marcelo.
Research on the immune response of oysters is motivated by the problems of infectious diseases potentially found in the farms. Over the course of the last few years, the development of genomic approaches has allowed us to make headway on characterising genes involved in the cup oyster's (Crassostrea gigas) innate immunity, particularly thanks to various programmes for analysing transcriptome, of type EST (Express Sequence Tag) and subtractive banks. Within the context of this work, over the course of which we have used the data from genomic research and we have also developed biochemical approaches, we were particularly interested in studying the proteins involved in reconnaissance reactions to LPS as well as to antimicrobial effectors. In an earlier part,...

Etude d'une prolifération hémocytaire chez la moule Mytilus edulis ArchiMer
Noel, Danièle.
Hemic proliferative disease in the bay mussel, Mytilus edulis, has been studied following mortalities in Washington State (USA). The disease has been reproduced in the labortory. The establishment of this experimental model led to study tumoral characteristics of the atypic hemocytes : ultrastrure, in vitro cultivation, transplantation. The infectious etiology of this tumor has been verified. It has been hypothesized to result from a viral infection since retrovirus-like particules have been observed following induction by bromodeoxyuridine. Specific monoclonal antibodies against atypic hemocytes have been obtained and characcterized

Etudes sur les mortalites larvaires de la coquille st Jacques Pecten maximus en ecloserie ArchiMer
Robert, Rene; Miner, Philippe; Nicolas, Jean-louis; Mazuret, Michel; Connan, Jean-paul.
Larval mortalities occurring in molluscan hatcheries have often been associated with bacterial contamination. Although batches of oyster and clam larvae have been routinely reared in the hatchery of Argenton without antibiotics, high larval mortalities have been recorded with Pecten maxirnus under similar conditions. For this species, an addition of chloramphenicol was found necessary. However, this chemical has now been banned in Europe. Thus either substitition products or an improvement in the rearing procedures is essential. Studies carried out have shown that neither a decrease in larval density (1 larvae. ml"l) nor sea water change frequency (1 per day) had any positive effects. Furthermore, elective substances such as sugars were not suitable and...

La reproduction des mollusques bivalves en écloserie ArchiMer
Devauchelle, Nicole.
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 pêcheries de buccin (Buccinum undatum L. : Gastropoda) du Golfe Normand-Breton. Eléments de gestion de la ressource ArchiMer
Santarelli Chaurand, Leonardo.
The whelk (Buccinum undatum) fisheries in the gulf between Brittany and Normandy have grown quickly over the past ten years. In 1983, 35 potters and 14 dories from Granville harbour and the Blainville maritime station landed 3,900 tonnes of whelk (for a value of 7.5 million francs). In spite of a sharp drop in profitability, the number of fishers is still growing. This study aimed to provide decision-making elements for rational management of the resource : stock abundance, catches per unit effort, mortality due to fishing effort and biological properties. In order to assess the impact of measures to organise the fishing effort on total catches in balance, two predictive models were used: Pella and Tomlinson's generalised production model and Ricker's...

Microalgues et nutrition larvaire en écloserie de mollusques ArchiMer
Robert, Rene; Trintignac, Pascal.
The production of live microalgae remains the only reliable technique for feeding bivalve mollusc larvae in a controlled environment. However, these algae must answer a number of size, nutritive value and mass-production criteria. The current knowledge in this field is assessed in this work which will lead us to the conclusion that only a few species meet these requirements.

Pathologie des invertébrés marins d'intérêt aquacole. Contribution et stratégies de recherches ArchiMer
Mialhe, Eric.
Les productions d'invertébrés sont prépondérantes en aquaculture marine qui est économiquement très importate pour un grand nombre de pays, notamment de la zone Sud. Cette activité est confrontée à de nombreux problèmes des pathologie qui remettent en cause sa périnnité et son développment. Jusque dans les années quatre-vingt, les travaux relatifs à la pathologie des mollusques et des crevettes ont essentiellement porté sur la description des agents pathogènes. La création en 1985 par l'ISTPM/IFREMER d'un laboratoire pourvu de tous les équipements nécessaires aux techniques de pathologie a permis de mettre en place un programme de recherches orienté vers le contrôle des maladies. Une double stratégie de travail a été alors défine pour apporter  à...

Valorisation des coproduits issus de la pêche des céphalopodes : applications à la seiche Sepia officinalis ArchiMer
Le Bihan, Estelle.
The cuttlefish Sepia officinalis, is one of the main species capted in the Basse-Normandie fisheries. These animals are principally exportated in eviscerated and frozen form to mediteranean countries and to Japan. Then, high quantities of co-products are available from factories transformation of cephalopods. Enzymological and biochemical studies on co-products demonstrated an elevated potential in the valorisation of viscera by silage technical. Two silages are developed in our laboratory: LBBMA4 and LBBMA25. Primarly, they are studed in vitro as substrate for the culture of micro-organisms. This study established that silage LBBMA25 permits to obtain good growth cinetic and biomass, with comparable results to commercial peptone. Secondary, silages can be...

Viruses of bivalve shellfish ArchiMer
Renault, Tristan.
Bivalve molluscs are filter feeders and as a consequence they may bioaccumulate in their tissues viruses that infect humans and higher vertebrates. However, there have also been described mortalities of bivalve molluscs associated with viruses belonging to different families. Mass mortalities of adult Portuguese oysters, Crassostrea angulata, among French livestocks (between 1967 et 1973) were associated with irido-like virus infections. Herpesviruses were reported in the eastem oyster, Pacific oyster and European flat oyster and lately in scallops and clams. Disseminated neoplasia, a proliferative cell disorder of the circulatory system of bivalves, although of uncertain aetiology, has been suggested to be caused by retroviral infections. Other viruses...
