| Growth of the japanese oyster, Crassostrea gigas was monitored during 4 years, by following the recruitment of the year 1978, held in rearing conditions. After three and half years, the average length was la cm and the average total weight was 80 g. Clear seasonal changes were observed on the growth in length and weight. An important loss in dry weight occured in July, during the release of gametes. Such losses constituted 29 %, 43 % and 60 % of the dry weight, respectively for individuals which were 2 years, 3 years and 4 years old. The higher instantaneous growth rates (G) were observed during spring and at the beginning of summer. Growth model of Von Bertalanffy, gave the best estimate for the length growth of the species. During the 1979-1982... |

| We studied and compared the effects of chloramphenicol antibiotic and garlic (Allium sativum), used as immunostimulants and growth promoters, on some physiological parameters, growth performance, survival rate, and bacteriological characteristics of Nile tilapia (Oreochromis niloticus). Fish (7±1g/fish) were assigned to eight treatments, with three replicates each. Treatment groups had a different level of Allium sativum (10, 20, 30, and 40g/kg diet) and chloramphenicol (15, 30, and 45mg/kg diet) added to their diets; the control group diet was free from garlic and antibiotic. Diets also contained 32% crude protein (CP) and were administered at a rate of 3% live body weight twice daily for 90 days. Results showed that the final weight and specific growth... |
