Effect of Oxygen Management on Culture Performance of Channel Catfish in Earthen Ponds
—Aeration allows for higher feeding rates and increased production of channel catfish Ictalurus punctatus in intensive and semi-intensive aquaculture systems. However, the effect of specific dissolved oxygen (DO) concentrations on various production parameters remains unknown. The purpose of this 2-year study was to determine the effect of daily minimum DO concentration on channel catfish produ...
متن کاملSupplemental effects of mixed ingredients and rice bran on the growth performance, survival and yield of Nile tilapia, Oreochromis niloticus reared in fertilized earthen ponds.
Unaffordability of commercial feeds to semi-intensive Nile tilapia, Oreochromis niloticus farmers has led to reliance on supplemental feeding and fertilization for nutrition of their fish without a scientific basis. This study compared the growth, survival, condition factor and yield performance of O. niloticus fed on mixed ingredients (MI) and rice bran alone (RB) diets reared in fertilized ea...
متن کاملGrowth Performance and Economic Benefits of Oreochromis Niloticus/clarias Gariepinus Polyculturefed on Three Supplementary Feeds in Fertilized Tropical Ponds
An experiment was conducted for 180 days at Sagana Fish Farm, Kenya, to evaluate the performance of two formulated pellet feeds and a locally available rice bran. A polyculture of Oreochromis niloticus and Clarias gariepinus in fertilized tropical ponds was used. Twelve 800-m2 ponds were used, and each pond was limed at a rate of 20,000 kg ha-1 and stocked at a rate of 19,375 ha-1 with sex-reve...
متن کاملShort communication:Effects of stocking density on growth performance and profitability of Labeo bata fry reared in earthen ponds
The aim of this study was to evaluate the effects of stocking density on growth, production and profitability of farming Labeo bata fry in earthen rearing ponds for a period of 60 days. Labeo bata, fry (mean initial length, 3.42 ± 0.07cm and weight, 1.02 ± 0.06 g) were stocked at 750, 1000 and 1250 decimal-1 in treatment-1(T1), treatment-2 (T2) and treatment-3 (T3) respectively, each with two ...
متن کاملEffects of season on ecological processes in extensive earthen tilapia ponds in Southeastern Brazil.
In Southeastern Brazil tilapia culture is conducted in extensive and semi-intensive flow-through earthen ponds, being water availability and flow management different in the rainy and dry seasons. In this region lettuce wastes are a potential cheap input for tilapia culture. This study examined the ecological processes developing during the rainy and dry seasons in three extensive flow-through ...
