A simple way of avoiding feed wastage in European seabass, Dicentrarchus labrax, under self-feeding conditions ArchiMer
Coves, Denis; Gasset, Eric; Lemarie, Gilles; Dutto, Gilbert.
Self-feeding systems allow fish to freely express feeding activity. A simple rod at the water surface can act as a trigger and provide fish with a way of obtaining pellets from a feeder. Such a rod presented to experienced European seabass, Dicentrarchus labrax, may lead to feed wastage, probably as a result of unintentional fish contacts with the trigger. Trigger protection screens have been designed to prevent fish contacting the trigger by chance, and the efficacy of such screens was tested. Nocturnal and diurnal feed delivery and feed wasted were compared under conditions where the rod was unprotected or protected by semi-cylindrical or cylindrical screens. Tests were conducted using an unrestricted self-feeding regime (reward: 0.2 g pellet per kg of...

Bilan de la première période d'élevage du silure glane (Silurus glanis) en condition tropicale et en circuit recyclé. (Collaboration Ifremer Palavas/Les Viviers de la Castillonne) ArchiMer
Gasset, Eric; Aubry, J.p.; Blancheton, Jean-paul.
La production Française du Silure glane stagne depuis plusieurs années pour plusieurs raisons principales: la qualité des alevins produits par les entreprises existantes n'est pas optimale, notamment pour un élevage intensif; les techniques de production extensives et semi-intensives en bassins de terre se heurtent à un profil d'évolution thermique naturelle inadapté à cette espèce d'origine continentale, ce qui ce traduit par des croissances aléatoires, des pathologies difficiles à maîtriser et une qualité de chair non optimale; les techniques intensives actuellement pratiquées ne permettent pas de produire économiquement des animaux de grande taiJJe dont la qualité de chair est optimale. L'entreprise « Les viviers de la Castillonne » maîtrise...

Comparative Allometric Growth of the Mimetic Ephippid Reef Fishes Chaetodipterus faber and Platax orbicularis ArchiMer
Barros, Breno; Sakai, Yoichi; Pereira, Pedro H. C.; Gasset, Eric; Buchet, Vincent; Maamaatuaiahutapu, Moana; Ready, Jonathan S.; Oliveira, Yrlan; Giarrizzo, Tommaso; Vallinoto, Marcelo.
Mimesis is a relatively widespread phenomenon among reef fish, but the ontogenetic processes relevant for mimetic associations in fish are still poorly understood. In the present study, the allometric growth of two allopatric leaf-mimetic species of ephippid fishes, Chaetodipterus faber from the Atlantic and Platax orbicularis from the Indo-Pacific, was analyzed using ten morphological variables. The development of fins was considered owing to the importance of these structures for mimetic behaviors during early life stages. Despite the anatomical and behavioral similarities in both juvenile and adult stages, C. faber and P. orbicularis showed distinct patterns of growth. The overall shape of C. faber transforms from a rounded-shape in mimetic juveniles to...

Dossier récapitulatif du développement de l’élevage du Platax orbicularis en Polynésie Française ArchiMer
Coeurdacier, Jean-luc; Gasset, Eric.
Platax orbicularis est l’espèce sur laquelle est basé le développement de la pisciculture en Polynésie française. Ce choix a été guidé par le fort potentiel économique de l’espèce dû à sa notoriété sur le marché local du poisson lagonaire estimé à 100 tonnes/an et à la diminution de sa population sauvage. Depuis 2001, date du démarrage d’un programme de développement de la pisciculture lagonaire en Polynésie, les travaux de recherche et développement menés conjointement par le Service de la Pêche de Polynésie (SPE) et l’IFREMER se sont focalisés sur l’acquisition de connaissances et de savoir-faire relatifs à la maîtrise zootechnique et sanitaire de l’élevage de ce poisson. En 2011 ce programme a atteint la première étape de transfert vers le secteur privé...

Effect of chronic ammonia exposure on growth of European seabass (Dicentrarchus labrax) juveniles ArchiMer
Lemarie, Gilles; Dosdat, Antoine; Coves, Denis; Dutto, Gilbert; Gasset, Eric; Person, Jeannine.
Chronic effects of ammonia were studied in juvenile seabass, Dicentrarchus labrax (mean weight= 11 g), exposed for 63 days to eight stable ammonia concentrations, ranging from 0.24 to 0.90 mg l(-1) unionised ammonia nitrogen (UIA-N), respectively, from 6.1 to 22.3 mg l(-1) total ammonia nitrogen (TA-N). Temperature (21.8 degreesC), pH (8.0), salinity (37.0 ppt), and oxygen concentration (over 80% saturation at the outlet) were maintained constant. Fish were fed using a self-feeder device, and they were starved during the last 8 days. Mortality of 28.9 and 42.6% occur-red within the first 8 days at the two highest UIA-N concentrations, respectively, 0.90 and 0.88 mg l(-1). From days 0 to 55, a 1.8-fold increase in weight gain was observed under the 0.90-mg...

Effect of chronic exposure to ammonia on growth, food utilisation and metabolism of the European sea bass (Dicentrarchus labrax) ArchiMer
Dosdat, Antoine; Person, Jeannine; Coves, Denis; Dutto, Gilbert; Gasset, Eric; Le Roux, Annick; Lemarie, Gilles.
The chronic effects of exposing sea bass (average initial weight 100 g) to ammonia in water at 22 degreesC were first evaluated over a 61-day period (period 1, P1) during which nine different groups were submitted to nine ambient ammonia levels ranging from 0.014 to 0.493 mg 1(-1) NH3-N (0.53-16.11 mg 1(-1) total ammonia nitrogen (TA-N)) and fed using self-feeders. At the end of P1, the fish were starved for 10 days (P2). Their recovery capacity was tested over 43 days (P3) after which the exogenous ammonia supply was stopped in all treatments and the fish were allowed to feed. After 20 days of exposure a highly significant effect of ammonia was evident from the decrease in feeding activity, voluntary feed intake (VFI) and specific growth rate (SGR), and...

Elevage intensif du loup Dicentrarchus labrax ArchiMer
Coves, Denis; Gasset, Eric.
Different seabass (Dicentrarchus labrax) intensiv rearing technics have been experimented in the pilot scale unit of our laboratory. During these upscalfing operation, the results obtained allow us to compare costs related to each fingemng production method. Closed system combined with early weaning with an efficient micropellet saves at least 69 % of direct production costs by comparison with an open system with Arternia during larval phase. However if closed systems are commonly used by private hatcheries, larval micropellets are always at experimental step.

Food in the Sea: Size Also Matters for Pelagic Fish ArchiMer
Queiros, Quentin; Fromentin, Jean-marc; Gasset, Eric; Dutto, Gilbert; Huiban, Camille; Metral, Luisa; Leclerc, Lina; Schull, Quentin; Mckenzie, David; Saraux, Claire.
Small pelagic fish are key components of marine ecosystems and fisheries worldwide. Despite the absence of recruitment failure and overfishing, pelagic fisheries have been in crisis for a decade in the Western Mediterranean Sea because of a marked decline in sardine size and condition. This situation most probably results from bottom-up control and changes in the plankton community toward smaller plankton. To understand such an unusual phenomenon, we developed an original and innovative experimental approach investigating the mechanisms induced by a reduction in the quantity and size of sardine prey. While experimentations offer the unique opportunity to integrate behavior and ecophysiology in understanding key demographic processes, they remain rarely...

Is total serum protein a good indicator for welfare in reared sea bass (Dicentrarchus labrax)? ArchiMer
Coeurdacier, Jean-luc; Dutto, Gilbert; Gasset, Eric; Blancheton, Jean-paul.
Reared sea bass were submitted to six stressful situations: hyperoxia with or without hypercapnia, increased stocking density in an open flow or recirculating system, transfer to another tank and nodavirus injection. The potentially negative impact of these factors on the lives of sea bass was investigated by measuring 9 water parameters and 19 fish parameters including total serum protein (TSP). TSP has already been used to evaluate stress. The present study investigates data of previous and new experiments, concentrating on the potential use of TSP as a routine indicator to assess welfare in sea bass reared on fish farms. In the current experiment, oxygen and carbon dioxide were seen to affect levels of TSP, but alterations were too erratic to enable...

Premiers résultats de sex-ratio, puberté et dimorphisme sexuel chez le Paraha peue (Platax orbicularis) en élevage. ArchiMer
Gasset, Eric; Joufoques, Vaiana; David, Rarahu; Maamaatuaiahutapu, Moana; Teissier, Alexandre; Tamata, Thierry; Dupieux, Sylvain.
Cette première étude du sex-ratio menée chez Platax orbicularis en élevage donne d’importantes indications dans l’optique d’optimiser la gestion des productions (1) de lots de futurs géniteurs issus d’un plan de croisement et (2) des lots d’alevins destinés à la production en cages. La poursuite du suivi des lots en cours et des nouvelles familles produites (sans tri des alevins et avec marquage magnétique individuel des poissons) permettra de confirmer sans doute ces indications et d’orienter par exemple le poids final des animaux produits par les pisciculteurs.

Regulation of feed intake, growth, nutrient and energy utilisation in European sea bass (Dicentrarchus labrax) fed high fat diets ArchiMer
Boujard, Thierry; Gelineau, Anne; Coves, Denis; Corraze, Genevieve; Dutto, Gilbert; Gasset, Eric; Kaushik, Sadasivam.
Three practical isoproteic (54% protein) diets were formulated to contain graded levels of crude fat (diet L: 10%, diet M: 20% and diet H: 30%). Each diet was assigned unrestrictedly to three and restrictedly to two replicate groups of fish (IBW 243 g). In unrestricted groups, increasing the dietary lipid level led to a significant decrease in voluntary feed intake without affecting growth rate. In the feed-restricted groups, daily growth rates increased with increasing dietary fat levels. There was a significant and inverse effect of the dietary fat content on whole body moisture and fat levels, with highest lipid (ca. 20%) and lowest moisture (ca. 58%) contents in sea bass fed diet containing the highest lipid level; muscle lipid concentration was...
