Current and proposed standards for commercial breeding of Danio rerio and other ornamental fish for production in laboratories and farms are different and require indigenize with the specific conditions of each production unit. But the general framework of zebrafish farming as a popular ornamental species and laboratory model has been reviewed by bioscientists for many years and can be consider...

production of new hybrids is important for growing aquaculture and protecting wild stocks of fish species. a hybrid between female asp × male kutum ( leuciscus aspius ♀ × rutilus frisii ♂) was produced and its growth performance was monitored in two rearing systems for 55 days. the fish held in earthen ponds exhibited higher performance compared to those held in concrete tanks. the results also...

 Euglenophyte bloom is a common problem in most of the aquaculture ponds in Bangladesh. In the present study we conducted an experiment to control euglenophyte bloom for getting better fish production using duckweed (Lemna minor) and lime. The experiment was carried out using four treatments, i.e., ponds were supplied with duckweed (T1), lime treatment (T2), both duckweed and lime (T3) and with...

A framework for the integration of poultry and fish production in the tropics and sub-tropics is proposed. Poultry may be integrated with fish culture in several ways and benefits extend to both. Both poultry production and processing wastes have value as nutrient inputs to fish and the water used for fish culture can be used for evaporative cooling of poultry and fertilization of crops. The co...

resistance of microencapsulated fish oil (mfo) in the rumen and its effects on fermentability of nutrients in the rumen was studied in 3 experiments. the key parameter in these studies was the amount of oil released from the microcapsules and their effects on gas production and rumen degradability in comparison with unprotected fish oil (fo). in the first experiment the effect of rumen and abom...
