Effect of dietary carbohydrate to lipid ratio on performance of Nile tilapia and enhancement of natural food in pond aquaculture

This 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 into three equally sized compartments, were assigned to one of the two diets, which differed in CHO:LIP ratio but had the same digestible protein to digestible energy (DP:DE) ratio (15.5 and 15.6 g/MJ). Ponds were fed equal amounts of crude protein. Three feeding levels (no, low and high) were nested in each pond in a split plot design.

Impact of substitution of fish meal by high protein distillers dried grains on growth performance, plasma protein and economic benefit of striped catfish (Pangasianodon hypophthalmus)

Modern aquaculture requires the reduction of the feeds cost, which can partly be achieved by minimal use of dietary animal protein. Therefore, this experiment assessing the nutritional potential of using high protein distillers dried grains (HP-DDG) in formulation of affordable striped catfish, Pangasianodon hypophthalmus, diet for more sustainable development of aquaculture. Four diets containing 0, 25, 50 and 75% HP-DDG as partial replacement of fish meal were fed to P.

Morphometric length-weight relationships of wild penaeid shrimps in Malindi-Ungwana Bay: Implications to aquaculture development in Kenya

The present investigation describes the biology of penaeid shrimps and their fishery studies on morphometric length-weight relationships estimated during the two monsoon seasons from Malindi–Ungwana Bay in Kenya. A total of 1238 penaeid shrimps belonging to Fenneropenaeus indicus, Penaeus monodon, Marsupenaeus japonicus, Metapenaeus monoceros, Penaeus canaliculatus and Penaeus semisulcatus were collected from the two seasons with South East Monsoon (SEM) recording more diverse species than the North East Monsoon (NEM).

Different levels of probiotics affect growth, survival and body composition of Nile tilapia (Oreochromis niloticus) cultured in low input ponds

A 7-month experiment was carried out to determine the effects of different levels of probiotics (baker's yeast (Saccharomyces cerevisiae) and Bacillus subtilis) on Nile tilapia (Oreochromis niloticus) reared in low input ponds.
