Abstract:
... Feed accounts for 60–80% of tilapia production costs, and high feed cost and limited feed access are major issues faced by fish farmers. A potential solution is for farmers to produce their own feeds using cheaper and locally available ingredients. This paper evaluates the feed formulation training implemented in Ghana as part of the Fisheries Commission's activities under the Ghana Aquaculture fo ...

Abstract:
... Integrated rice-carp farming is commonly employed on Hani terraces in China. However, the altitude within a Hani terrace can vary greatly, and thus the solutions for such a farming approach must vary with altitude. Research on common carp food sources in an integrated rice-carp farm at different altitudes helps to understand the food requirements of carp across periods and provides guidance for pr ...
