Effect of broodstock density on Oreochromis shiranus fry production in hapas
(1993)Type: Journal ArticleOreochromis shiranus broodstock were stocked in 3 x 3 x 1 hapas for 413 days in Malawi at 1.7, 1.0, and 0.7/m super(2) (sex ratio was 1 male:2 females). First sampling was done 14 days after stocking and every 21 days ... -
Effect of dietary carbohydrate to lipid ratio on performance of Nile tilapia and enhancement of natural food in pond aquaculture
(2020)Type: Journal ArticleThis study tested the effect of two diets differing in carbohydrate to lipid (CHO:LIP) ratio (4.7 vs. 19.5 g/g) on the contribution of natural food and the total fish production in tilapia ponds. Eight ponds, each divided ... -
Effect of dietary probiotic Biogen supplementation as a growth promoter on growth performance and feed utilization of Nile tilapia Oreochromis niloticus (L.)
(2006)Type: Journal ArticleProbiotic microbial feed supplements are gaining wide acceptance in livestock production, and may be applicable to aquaculture production systems. The present study was conducted to examine probiotic treatment in the ... -
Effect of dietary protein level on fish growth, economic and ecological performance of three types of feed for Nile tilapia (Oreochromis Niloticus)
(2020)Type: Internal ReportWith a growing world population, food production needs to increase as well. Part of the human diet is fish, and with world fisheries declining, the aquaculture industry is increasing. Nile tilapia is a major aquaculture ... -
Effect of dietary protein to energy ratio on performance of nile tilapia and food web enhancement in semi-intensive pond aquaculture
(2018)Type: Journal ArticleWhen fish have only access to formulated feed, the optimal dietary protein to energy ratio (P:E) for tilapia ranges between 18 and 23 g.MJ<sup>-1</sup>. In pond culture, where natural foods complement administrated feed, ... -
Effect of dietary protein to energy ratio, stocking density and feeding level on performance of Nile tilapia in pond aquaculture
Type: Journal ArticleThere is growing interest to understand the dietary P:E requirements for the supplemental feed used in tilapia pond culture where natural food contributes to production. In an on-farm trial, we tested the effect of lowering ... -
