Despite lower production of fingerlings, consistently higher net benefits were obtained from T1 than those from T2 and T3. When the stock density is 15000/ha it produces a survival rate of 76.67%. ABSTRACTThis study aimed to evaluate the growth performance and resistance to salinity stress of striped catfish juvenile reared in biofloc with different feeding rate (FR). “The electrochemical process maintains the water quality throughout the growth cycle of the shrimp. An experiment was conducted for six months to demonstrate the suitability of biofloc technology in farming system of mono-sex GIFT tilapia Oreochromis niloticus. A total of 43 genera of phytoplankton and 16 genera of zooplankton were identified from the pond water. One component of the project incorporated reduced-feeding protocols and polyculture technology to improve production culture efficiencies, particularly in indigenous, air-breathing fishes such as Shing and Koi (nutrient rich and hardy fish). The treatments applied in this study were rearing the fish in biofloc with FR 5% and 8% of biomass per day, and rearing the fish with a FR of 8% per day without biofloc system as the control.

Biofloc Production systems Environment. Based on the results of the study, the use of periphyton as feed is more economically profitable than wheat bran and even commercial tilapia feed for the culture of monosex tilapia in ponds. A one year study was conducted from January-December 2014 to investigate the reproductive biology of Vietnamese Microscopic observation on matured testes found spermatocytes, spermatids and spermatozoa stages during the In the present experiment based on the highest growth, survival, production and net benefits of the fingerlings of A. testudineus with three treatments in nursery ponds, 1.0 million hatchling/ha (T1) appears to be the best stocking density. i.e. Unstable electricity causes production failure. Protein (51.19%) and lipid (13.84%) content in harvested prawns was significantly higher in the biofloc system, which we ascribe to the nutritional contribution of complementary food. During the research, water quality was in tolerance range for Climbing perch larvae rearing: temperature was 26-30ºC, pH 6 -7, DO 3.4- 4.0 mg L-1, and Ammonia 0.001-0.043 mg L-1. Chital Fish Seed.
