Effect Of Formulated Feed (containing Common Bean And Leftover Flour) On Growth Performance Of Nile Tilapia (oreochromis Niloticus L.) In Earthen Ponds At Nono District, Ethiopia
Fish feed plays a critical role in aquaculture; it influences production costs, fish growth, health and fish production. One of the approaches to tackle this problem has been to experimentally test the use of agro-industrial byproducts to grow fish in ponds. Thirty (30) fingerlings of Nile tilapia were stocked in each pond and fed with five percent of their body... Continue here
