Abstract
Tilapia are an economically important group of fish. They have a short generation period of 3-6 months, and exhibit successive breeding. In addition, their fast growth, herbivorous or omnivorous feeding habits, high food conversion efficiency, ease of spawning, ease of handling, resistance to disease and good consumer acceptance make this group of fish highly popular in aquaculture in Asia, Africa and other developing countries. Tilapia have been the subject of research on pollution effects over the last decade. The purpose of this study was to determine growth, accumulation and depuration responses of 2 strains of the Nile tilapia, Oreochromis niloticus, chronically exposed to a mixture of heavy metals including cadmium, zinc and mercury.

Effects of some water-soluble vitamins on the growth of Penaeus monodon juveniles
Catacutan, M.; Kanazawa, A. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The response of Penaeus monodon juveniles (ave. wt.= 0.076 g) in terms of survival and growth rates to vitamin test diets was observed in a 35-day feeding experiment. The prawns were reared in 60-ℓ oval tanks containing filtered seawater in a flowthrough system of ambient temperature and salinity. The treatments consisted of a control (complete vitamin mix), a vitamin-free diet and nine other diets, each lacking one of the vitamins in the mixture. At the end of the feeding trial, the survival rates in all treatments ranged from 80 to 100%, while weight gain ranged from 74 to 40%. Significantly lower weight gains were obtained from choline chloride-free diet (P<0.05) and vitamin-free and inositol-free diets (P<0.01) than from control. -
Effect of dietary organic acid salts, potassium diformate and sodium diformate on the growth performance of male Nile tilapia Oreochromis niloticus
Cuvin-Aralar, Maria Lourdes A.; Luckstaedt, Christian; Schroeder, K.; Kühlmann, Kai-Jens (Verlag Natur & Wissenschaft, 2011)The effect of two organic acid salts on the production performance of juvenile male Nile tilapia Oreochromis niloticus were studied in two separate experiments. In the first trial the fish (initial size: 7.84kg) were fed commercial feed supplemented with 0,3% potassium diformate (KDF) while in the second trial the fish (initial size: 16.48 kg) were fed diets supplemented with 0,3% sodium diformate (NDF). The control group for both trials used the same commercial fish feed with no supplementation. The feeding trials lasted for 74 and 78 days, respectively. Results showed that the supplementation of either KDF or NDF significantly improved growth and feed conversion of male Nile tilapia compared to the control group. The fish in the KDF treatment had a mean final weight of 51.4g and FCR of 1.81 compared to 45.4g and 1.97, respectively, for the control. Mean final weight and FCR of fish in the NDF treatment were 66.2g and 0.69, respectively, while those of the control were 58.7g and 0.77. The condition factor of the fish in both trials was not affected by treatment. -
