Abstract

In order to promote the nourishment of carp in farming, four foods have been created from traditional raw materials and containing different quantities of locally produced banana flour 3%, 6%, 10%. We tested these foods which contain 36% crude proteins and 8% lipids on carp fry with an initial weight of 9g. After 50 days of experiment, the final weights of the fish fluctuated between 121.53g and 122.45g depending on the treatments used. The food containing 10% banana flour and the control food showed the highest growth and food transformation rates, with specific growth rates (SGR) of 5.18%/d and 5.14% /d as well as a conversion rate of 1.17 and 1.15 while the food with 6% banana flour obtained a SGR of 5.15 and a conversion index (CI) of 1.15 while that the food with 3% obtained a SGR of 5.14 and a CI of 1.16. Thanks to this test, we were able to observe the impact of bananas on the premature development of tilapia. We will continue to study the use of local agri-food by-products and waste in feeding this fish.

Abstract

This study examines the quality of water used to farm tilapia and carp in Antsirabe, Madagascar. The physico-chemical parameters of 95 farm sites were analysed to determine and assess their compliance with the quality standards required for sustainable aquaculture. Samples taken at several farm sites revealed an average pH of 6.92, an average conductivity of 105µS/cm, an average oxygen level of 6mg/l, a temperature of 22°C and an average salinity of 0.054/00. These results highlight the importance of water quality management in aquaculture practices in Antsirabe, helping to ensure the economic and environmental viability of fish farming in this region.
