Ajustement de certains paramètres de culture par bouturage de Gracilaria verrucosa (algue rouge), Hudson papenfuss, dans le lac de Bizerte (Tunisie) OceanDocs
Ksouri, J.; Mensi, F.; Ben Said, R..
Cette étude, réalisée dans la partie Nord-Est du lac de Bizerte du premier Avril au 30 Juin 1999, porte sur l’étude de l’effet des deux paramètres, distance entre les touffes et poids initial des touffes, sur le rendement de culture par bouturage de Gracilaria verrucosa selon le mode des boudins de sable. Il en ressort que les conditions optimales de culture de cette espèce sont engendrées par un poids initial de 200 g, une distance entre les fragments de thalles de 30 cm et une récolte impérativement vers la fin du mois de Juin. Dans ces conditions, on enregistre un passage du poids de 200 g à 1087 g, un taux de croissance spécifique de 2,20 et une densité finale de 3,74 kg/m².

An inexpensive turbidimeter for the automatic culturing of filter feeders OMA
Versichele, D.; Bossuyt, E.; Sorgeloos, P..
Automatization in the food distribution is necessary for the controlled culturing of filter feeders in high densities. Numerous devices have been described to distribute specific quantities of food suspension at preset time intervals (cf. review in Kinne, 1977). The number of systems which, however, add food whenever a preset critical turbidity of the medium is exceeded are rather limited. They furthermore are either very expensive (sophisticated equipment) or have to be cleaned very often (cf. review in Sorgeloos et al., 1976). We tried to simplify the technological complexity of the existing systems and developed an inexpensive, automatic, self cleaning food distributor. This apparatus measures the turbidity of the culturing medium which is pumped into a...

Cofeeding of phospholipids to turbot <i>Scophthalmus maximus</i> L. larvae as a tool to reduce live food consumption OMA
Dhert, P.; González Félix, M.; Van Ryckeghem, K.; Geurden, I.; Thysen, F.; Lebegue, E.; Lavens, P.; Sorgeloos, P..
The possible benefits of feeding a formulated diet, together with <i>Artemia</i> , to first-feeding turbot larvae were investigated. Five dietary regimes were used: control ( <i>Artemia</i> only), cofeeding with a diet rich in phospholipid (PL) from bovine brain, cofeeding with a diet rich in free fatty acids (FFA) from the same source, cofeeding with a commercial diet (Lansy A2), and a formulated feed only (PL-rich diet). All treatments with artificial diets and the control treatment that received <i>Artemia</i> exclusively gave a similar survival rate of the fish at day 29. Cofeeding with artificial diets resulted in a lower growth rate than the control treatment. Cofeeding the larvae with PL-rich or FFA-rich diets did...

Concevoir des structures pour l'élevage des poissons en mer ArchiMer
Priour, Daniel.
The quick evolution of fish farming in Europe, and its development towards the open sea needs suitable farming tools. These tools must withstand the difficult sea states, but they must be easy to use, well adapted to the fish farming and not too much expensive. This book helps the design of such tools. It defines the solicitations of the sea on all the structures, and presents rules and methods to control these solicitations. Here, a structure is composed of a rearing support, a mooring system and equipments. This book describes these components, class them and gives lists of providers. The rearing support can be a cage, a group of cages or a boat. The support can float or to be submersible. The mooring system can be made up ropes, chains, anchors,...

Differentiation de juveniles de Chlamys varia et Chlamys opercularis ArchiMer
Morizur, Yvon.
The recent developments in collecting techniques for spat of Chlamys operoularis and Chlamys varia make it necessary to find criteria for separating these two species at early life stages. Biométrie criteria for differenciating between species have been found to be usable on individuals of a height superior to 3 mm. A quick différenciation of smaller individuals is possible by observation, under light microscope, of the périostracum external morphology on left valves.

Effect of season on controlled propagation of the African catfish, clarias gariepinus (Burchell 1822). OceanDocs
Ayinla, O.A.; Nwadukwe, F.O..
The effect of season on the controlled propagation of C. gariepinus was investigated. The hypophysation of C. gariepinus using the pituitary extract from the sacrificed C. gariepinus was carried out from July, 1987 to June 1988. The female broodstock weight ranged from 0.50kg while the male weight, from 0.5kg to 0.6kg. The condition factor of the female broodfish was more or less uniform (1.3 to 1.7). The results showed that there was peak production of eggs by the female during the rainy season. Eggs production for rainy season ranged from 28,000 eggs/kg body weight in June to 37,600 eggs/kg body weight in August. The percentage hatching of the fertilized eggs was also higher in the rainy season than the dry season. The highest hatching of the...

Effects of age and environment on the summer mortality in cupped oyster Crassostrea gigas during the first two years ArchiMer
Degremont, Lionel; Boudry, Pierre; Soletchnik, Patrick; Bedier, Edouard; Ropert, Michel; Samain, Jean-francois.
Three successive generations were produced between 2001 and 2003 to assess to what extent genetic variability exists for survival in juvenile oysters Crassostrea gigas. For each generation, two groups were selected for their high ("R" for resistant) and low ("S" for susceptible) survival. Significant differences in mortality were observed during the first year in Riviere d'Auray (RA) (Brittany-France). However, low and similar mortality were observed for both groups, with no significant difference between groups in the first and second generation in this site, where the first summer is the critical, sensitive period with a clear age effect. In Baie des Veys (BDV) (Normandie-France), where mortalities usually mainly affect adults, mortality between groups,...

Experimental studies on acclimatization of marine shrimps, Penaeus monodon and Metapenaeus monoceros to freshwater OceanDocs
Rathacharen, S.; Laxminarayana, A.; Venkatasami, O.; Codabaccus, B..
The adult shrimps, Penaeus monodon and Metapenaeus monoceros were induced to mature and spawn by eyestalk ablation. The larvae of both the species of shrimps were reared up to post larval stage on a diet of the phytoplankton, Chaetoceros calcitrans. The post larvae of M. monoceros were fed with artificial feeds only, whereas the post larvae of P. monodon were fed on small quantities of Artemia sp. in addition to artificial feed. After post larval stage, PL-20, the post-larvae were acclimatized to freshwater. Acclimatization was tried for different periods ranging between 2 and 20 days. The best survival rate was obtained for an acclimatization period of 5 days. Results obtained so far showed that the growth of P. monodon was significantly higher in...

International study on <i>Artemia</i> : 24. Cold storage of live <i>Artemia</i> nauplii from various geographical sources: potentials and limits in aquaculture OMA
Léger, P.; Vanhaecke, P.; Sorgeloos, P..
Freshly-hatched <i>Artemia</i> nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for <i>Artemia</i> from Chaplin Lake and Buenos Aires, naupliar viability was very high even after 48 h storage, and did not decrease significantly after a 24 h post-storage transfer to 25°C. Neither the naupliar dry weight nor biochemical composition changed significantly during refrigeration for most strains tested. Comparative culture-tests with stored and freshly-hatched nauplii as food for juvenile marine mysids <i>Mysidopsis bahia</i> M. and larval carp <i>Cyprinus carpio</i> L. revealed similar production performances.

International study on <i>Artemia</i> : 48. The effect of temperature on cyst hatching larval survival and biomass production for different geographical strains of brine shrimp <i>Artemia</i> spp. OMA
Vanhaecke, P.; Sorgeloos, P..
The effect of temperature on different geographical strains of <i>Artemia</i> has been studied for the following criteria: the hatchability of the cysts, the resistance of the larvae to high temperature (34°C) and the biomass production of larvae cultured under standard conditions. Experimental temperatures ranged from 25° to 37°C for the hatching criteria and from 20° to 32.5°C for the biomass production.Both the hatching percentage and growth performance are affected by temperature. However, the relative and quantitative impact of temperature varies widely among <i>Artemia</i> strains. This is also the case for the temperature resistance of the larvae. The impact of increasing temperatures on cyst hatching as well as the...

Larval rearing techniques and stock enhancement of silver seabream (Rhabdosargus sarba) in Mauritius OceanDocs
Baccus, H.; Ramsaha, S.; Rathacharen, S.; Hassea, R.; Auliar, I.; Codabaccus, B..
The silver sea bream (Rhabdosargus sarba), has great commercial value in Mauritius. The species is a potential candidate for aquaculture. The sea bream, a winter spawner, was successfully induced to breed in captivity with HCG (Human Chorionic Gonadotropin) hormone injection (250 IU/kg body weight) in 1989 at the Albion Fisheries Research Centre. In 1997, the Coastal Fisheries Resources and Environment Conservation Project of Japanese International Cooperation Agency (JICA) was launched to enhance the stock of the silver sea bream in the lagoon. This species breeds under hatchery conditions during the spawning season. Annually, the hatchery-produced sea bream fingerlings, of 2.0 to 2.5 cm body length, were released in the coastal areas. The larval rearing...

Liquid chromatographic determination of efficacy of incorporation of trimethoprim and sulfamethoxazole in brine shrimp (<i>Artemia</i> spp.) used for prophylactic chemotherapy of fish OMA
Nelis, H.; Léger, P.; Sorgeloos, P.; De Leenheer, A.P..
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...

Live-food mediated drug delivery as a tool for disease treatment in larviculture: 2. A case study with European seabass OMA
Chair, M.; Romdhane, M.S.; Dehasque, M.; Nelis, H.; De Leenheer, A.P.; Sorgeloos, P..
The purpose of this study is to investigate the possibility of oral delivery of the antibiotics Trimethoprim (TMP) and Sulfamethoxazole (SMX) to marine fish larvae through incorporation of these antibiotics into the live food organism <i>Artemia</i>. SMX and TMP were selected for their wide range action against gram negative pathogenic bacteria and because of their limited solubility in seawater. Ormetoprim-Sulfadimethoxine (brand name Romet-30) is a new combination of a similar antimicrobial drug used in aquaculture. Diseased penaeid larvae fed Romet-30 through the food chain exhibited greater survival than the untreated ones. In an earlier study Verpraet have described a technique for bioencapsulating high doses of more than 500 mu g TMP +...

Onshore nursery rearing of bivalve molluscs in Belgium OMA
Claus, C.; Maeckelberghe, H.; De Pauw, N..
From October to April the growth of spat of <i>Ostrea edulis, Crassostrea gigas</i> and <i>Venerupis semidecussata</i> in an onshore nursery was recorded as a function of water temperature and food level. The results of this study indicate that even very eutrophic water, such as that of the Sluice Dock at Ostend, Belgium, does not provide enough microalgae to sustain growth of bivalve spat during winter, irrespective of whether the water is heated or not. It is necessary to supply additional food (cultured live algae). Food shortage for three months at higher temperature induced a stress situation resulting in high mortality rates, even after transferring all the spat into an optimal combination of temperature and food availability.
