L'aquaculture du Macrobrachium rosenbergii aux Antilles Francaises ArchiMer
Lacroix, Denis.
The aquaculture of Macrobrachium rosenbergii is launched in Martinigue by the regional council in 1976. A first "green water" type hatchery is built and provides juveniles to the first ponds. In 1978, CNEXO is asked to cooperate in scientific assistance. A new hatchery is built with COP "clear water" system and produces in 1980. The development of ponds (20 ha) needs the increase of the hatcheries capacity, which is now done with one single method and intensive larval first stage (7-8 millions PL. cap). In Guadeloupe, the first ponds started in 1978. Two cooperatives and 11 ha of ponds at this time have determined the construction of CNEXO in the construction of a regional hatchery. A small light one is already under production since July 83.

The Australian mariculture industry: Finfish, molluscs and crustaceans. ArchiMer
Baker, J; Kenway, M.
Australia's interest in mariculture has been comparatively recent when compared with the developments in many other Pacific countries. Two exceptions are native oysters, cultivated for food since the late 1880's, and pearl oysters which have been cultured, particularly in the northern part of Australia, following the initial work of Saville-Kent.

Selection of finfish species for aquaculture development in Martinique (FWI). ArchiMer
Thouard, Emmanuel; Soletchnik, Patrick; Marion, J.
Since 1981, in Martinique, a programme of selection of fishes suitable for aquaculture has been conducted. Zootechnical and socio-economical constraints have led to the choice of three species, endemic and exotic: the palometa (Trachinotus goodei ), the red drum (Sciaenops ocellata ) and the red florida hybrid (Oreochromis sp.).

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...

Growth response of clarias gariepinus (Burchell 1822) on silage-based diets. OceanDocs
Ayinla, O.A.; Akande, G.R..
The feeding trial of C. gariepinus using three silage based diets and one fish meal based diet was carried out in concrete tanks. The four experimental diets were fed to C. gariepinus fry of relatively the same size. At the end of 8 weeks feeding trial the fish increased from their initial body weight of 0.2g, 0.4g, 0.4g and 0.4g to average final weights of 21.2g 15.4g, 12.8g and 13.8g respectively. The diet containing 41.1% resulted in the least food conversion efficiency of 1.2 over the eight weeks period. Of the experimental treatments the diets containing the highest level of fish silage (41.0%) performed better than any of the other two treatments of 19.0% and 33.5% fish silage contents. Apart from the nutritional superiority of 14% fish meal-based...

Preliminary studies on the early rearing of clarias gariepinus in plastic pools OceanDocs
Ayinla, O.A.; Nwadukwe, F.O..
The larvae of clarias gariepinus were reared in 3 plastic pools at the stocking dencity of 194.25 fry/m2 with different rates of water exchange an plankton growth for each pool. The fry(6.2mm length) in each plastic pool were fed with supplementary diet of milk powder/egg yolk suspension in the ratio of 1:1 which was replaced with fish meal paste after 8 days of rearing. After 20 days of rearing the fry in the pool with the most plankton bloom and pebles on the bottom, had the lowest motality and maximum total length of 30.4+- 7.8mm. Pleurococcus sp, Navicula sp were found to be in highest concentration in the pool where the best growth pattern was recorded

Azolla pinnata as a possible replacement of palm kernel cake in the diet of oreochromis niloticus. OceanDocs
Abioye, O.M.; Adeyemo, A.A.; Ayinla, O.A.; Bekibele, D.O..
Azolla pinnata as a possible replacement of the palm kernel cake in the diet of Oreochromis niloticus. Compounded diets from a control with palm kernel cake replaced at varying levels of 0, 20, 40, 60, 80, and 100% with the aquatic fern (oven dried Azolla pinnata) were fed to Oreochromis niloticus for twelve weeks to determine the acceptability and utilization of the fern in the diet, verify the nutritional influence of the fern on the performance of the fish and possible optimum palm kernel cake replacement level. The fish readily accepted the test diets. Better growth responses were recorded in the treatments containing Azolla pinnata meal. The best response was observed in the 20% replacement level, thereby suggesting an optimum replacement. However...

Studies on the nutrition of brackish water catfish - Chrysichthys nigrodigitatus OceanDocs
Igbinosun, J.E.; Talabi, S.O.; Roberts, O.O.; Okolie, E..
The nutritional effects of the complete or partial replacement of fishmeal by Soyabean meal in the diets of catfish were investigated. Four diets A, B, C, and D in which 34% of fish meal was replaced weight by weight with 0%, 10%, 20% and 34% of Soya-bean meal respectively were fed to four groups of brackish water catfish for six weeks. Results showed that although the digestibilities of proteins were almost equal in all the four groups, the groups fed diet D in which 100% of the fishmeal had been replaced by Soyabean had the least growth as compared to A, B and C. Nevertheless, the group fed diet D (with the least growth) had an economy of gain twice that of the group fed diet A. The liver and heart indices and the proximate compositions of the muscle...

The food and feeding habits of African mud catfish clarias gariepinus (Burchell 1822) caught from the wild. OceanDocs
Ayinla, O.A..
Food and feedigng habits of Clarias gariepinus (Burchell 1822) was studied died using numerical, frequncy of occurrence and volumetric analysis. The three different stages of development of C. gariepinus collected from Olupanna Reservoir in Oyo State of Nigeria were investigated. Phytoplankton was the most important food item of C. gariepinus fingerling, juvenile and adult on the basis of numerical and frequency of occurance methods. Volumetrically insects and insect parts were the most important in the diet of fingerling while the volumes for both phytollankton and fish remains were similar. Fish and fish remains were more important in the diet of juvenile C. gariepinus than the other food items by the volumetric method. Also fish and fish. Remains...

The effect of replacing fish meal (tuna waste with graded levels of toad meal in diet for Clarias gariepinus fingerlings (Bruchell 1822) OceanDocs
Bekibele, D.O.; Ayinla, O.A.; Saidu, A.A..
A feeding trial was conducted on the replacement of fish meal (Tuna waste) with oven dried toad meal in diets for Clarias gariepinus fingerlings average weight 3.6g in concrete tanks for 56 days. Average weight gain, % weight gain, specific growth rate, apparent digestibility coefficient, protein efficiency ratio and feed conversion ratio showed no significant difference as the level of toad meal increased. The only recorded mortalities occurred in the control and treatment of (25% replacement level) at 16.67% and 8.33% respectively and may have been due to handling stress. Toadmeal compares favourably with fish meal (tuna waste) and could be conveniently used in its replacement.

Structure génétique des populations de trois espèces de poissons de récifs cubains : Stegastes partitus, Haemulon flavolineatum et Acanthurus tractus. OceanDocs
Castellanos Gell, J..
La dispersion des poissons de récifs dépend pour une large part, de l‟existence de larves pélagiques qui peuvent être transportées au sein des courants marins loin de la population source (Cowen et coll., 2000). Ceci est mis clairement en évidence chez les espèces territoriales, celles ayant un mode de vie benthiques ou celles ayant une phase adulte avec de faibles capacités de dispersion. De l‟efficacité de ce transport dépendra donc l‟existence de populations formant un continuum, plus ou moins connectées, tout le long des zones de récifs. Toutefois, ce phénomène de dispersion est beaucoup plus complexe et implique d‟autres facteurs comme le comportement larvaire, la durée du stade larvaire pélagique, sa distribution vertical. D‟autre...

Cultivos de moluscos bivalvos OceanDocs
Pascual, M.S.; Zampatti, E.A..
Bivalve culture in Argentina is beginning to develop commercially. Research was carried out at the North Patagonian gulfs (San Matias, San Jose and Nuevo)and focused three native species: the tehuelche scallop Aequipecten tehuelchus, the puelche oyster Ostrea puelchana and the common mussel Mytilus edulis platensis. Results achieved on each of these three species were different. In the case of scallops, the development of commercial aquaculture did not seem promising for many years due to the fact that production was sustained by natural populations: the dredge fishery of the San Matias Gulf and the diving fishery of the San Jose Gulf. Preliminary culture experiments dealt with larval fixation on artificial collectors and growth to commercial size on...
