Water quality management in earthen ponds using an optimum carbon/ nitrogen ratio
The main goal of the current study was to evaluate the effects of C/N ratio on water quality parameters and production level at high stocking density pond. The C/N ratio of the experimental ponds were arranged by addition of corn starch to the pond. There were three treatments in the current study; control one without corn starch addition and treatments two and three which contain C/N rations o...
متن کاملEffects of stocking densities on growth and survival of Thai Sharpunti (Barbonymus gonionotus) in earthen ponds
The present study was conducted over 4 months during 1 September to 30 December 2005 to observe the effects of stocking density on growth and survival of Thai Sharpunti, Barbodes gonionotus in 3 earthen ponds of size of 2.8 decimal each. The stocking densities of 80, 100 and 120 fish/decimal were treated as T1, T2 and T3, respectively. All the treatments were subjected to the same feeding regim...
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 کاملEffect 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 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 ...
