Probiotic microbial feed supplements are gaining wide acceptance in livestock production, and may be applicable to aquaculture production systems. The present study was conducted to examine probiotic treatment in the fingerling diet of Nile tilapia Oreochromis niloticus (L.). A total of 240 of Nile tilapia fingerlings (weight ranged from 22.96 to 26.40 g) were divided into five experimental groups. The experiment was conducted for 120 days.

This policy brief provides information on the scale of HIV/AIDS in the fisheries sector in Africa, the reasons why prevalence is so high and how this affects fishing communities. Access to health services and antiretroviral therapy is then briefly reviewed, as are some of the limited experiences directly targeting HIV/AIDS programmes to fishing communities. The concluding discussion highlights areas where more work is needed on policy development, action and further research.
