Effect Crude Protein Levels on the Broodstock Spermatic Quality of Nile tilapia (Oreochromis niloticus)

The objective of this study was to evaluate the effect of different feed management on the quality of effluent water generated in Nile tilapia (Oreochromis niloticus) culture ponds. Feed was supplied as follows: natural food, and pelleted, extruded or minced ration. The study was conducted during 19 weeks in 12 continuous water exchange ponds of 300 m² each, with a population of male Nile tilapia juveniles, in a density equal to 1.7 fish m-2. Feeds contained 30% crude protein, 3,000 kcal digestible energy, and were supplied twice a day. Natural food consisted of chicken manure. Temperature, dissolved oxygen, pH, total phosphorus, total nitrogen, chlorophyll a and suspended solids were monitored weekly in the supplying and effluent water. Water residence time was also determined for the ponds. In general, effluent water quality decreased in all treatments.

Soya Bean Meal

Pigeon pea (Cajanus cajan) meal was substituted for soybean meal in the practical diets for Nile tilapia Oreochromis niloticus fingerlings. Six iso-nitrogenous diets (35% crude protein) were formulated in which heat-treated soybean meal was replaced at varying levels (0, 20, 40, 60, 80 and 100%) with protein from pressure-cooked and sun dried pigeon meal (23% crude protein). Nile tilapia fed 60% pigeon pea meal had significantly (P<0.01) better growth response and nutrient utilisation. Growth was depressed in low pigeon pea fish and also in high (above 60%) pigeon pea diets. The poorest feed conversion ratio was observed from 100% pigeon pea fed fish.
