| The possibility of wholly or partially replaced wheat offals with dried water hyacinth meal in the diets of Tilapia zillii fingerlings was investigated. Four diets, A, B., C and D were formulated. Diet A contain 45% wheat offal in addition to fishmeal and soyabean meal as sources of protein. B and C were diets in which 100% and 50% of the wheat offals were replaced by dried water hyacinth meal respectively. Diet D had 80% water hyacinth meal and an additional 18% Casein as the only other source protein. Results of four weeks feeding trial showed that Tilapia zillii fingerlings would not ingest diet D containing 80% water hyacinth meal without the addition of fishmeal. Water hyacinth meal could not wholly replace wheat offals in Tilapia diets unless at... |

| Fishmeal is a vital component used in animal feed formulations. The present status of fisheries industry in Nigeria is mainly artisanal. The artisanal sector contributes over 90% of the total landing while the industrial sector contributes less than 10%. The artisanal sector is thus a potentially huge source of fish meal. Possible source of raw materials for fish meal production at cottage level includes artisanal seasonal glut and waste from the consumption industry. These two sources cannot sustain the setting up of fish meal plant on a large scale. A method to produce fish meal from artisanal fishing activities and waste from canning industry was investigated using simple processes of cooking, pressing and drying. The fish meal produced by direct... |

| Pelleted feeds A.B, C and D containing 4% 3%, 2% and 1% sodium alginate respectively were tested for water stability in terms of floatation time, sinking rates and crumbing rates (on getting to the bottom of the tank). Results showed that although all the pellets had Zero Floatation time, it took pellets from the D group longer time to sink. A and B pellets sank at equal rates. The crumbling rates on getting to the bottom tended to decrease with decreasing levels of binder. When the diets were later fed to four groups of Tilapia fingerlings for seven weeks, results showed that the growth rate, feed conversion efficiencies and protein efficiency rations followed the trend C> D> B> A. It is therefore suggested that 2% level of alginate binder is... |
