Effect of dietary carbohydrate to lipid ratios on growth, feed conversion, protein utilisation and body composition in climbing perch, Anabas testudineus

  An 8-week feeding trial was conducted in a static indoor rearing system with 15 cylindrical fibre glass tanks (80 cm diameter, 75 cm deep, 70-L each) to investigate the optimum carbohydrate to lipid ratio (CHO:L ratio) in climbing perch, Anabas testudineus (2.15 ± 0.07 g). Five isonitrogenous (40% crude protein) and isoenergetic (17.71 kJ g-1 gross energy (GE)) fishmeal based...

The sediment characteristic and benthic macro-invertebrate fauna of some fish ponds in Ife north local government area (LGA), Nigeria

  This study investigated the sediment characteristics as well as the taxonomic composition of macrobenthic invertebrate faunae of some ponds in Ife north local government area,(LGA) Nigeria. The sediments were generally sandy, moderately acidic (pH range of 3.8 to 5.8) and well drained. The organic carbon of the sediment were within the usual range of 0.5 to 5% organic carbon while the nutrients...
