In the process of grass carp breeding, the cost of feed can account for 70%-80% of the whole. The quality of the feed affects the quality and quality of the fish. To raise the fish, the scientific feeding and management of the feed are very important. In fish ponds for cultivating grass carp, water quality, bottom quality, feed, seed, animal protection use, and external facilities are all key factors that affect the success or failure of aquaculture. Among them, feed feeding is closely related to water quality and sediment quality.

Perch is one of the common economic fish, and it is also a species for the development of marine aquaculture. At the same time, perch is also one of the important economic fish that grow naturally. It has been artificially cultivated for nearly 20 years. In recent years, driven by the market economy, Big breakthroughs have been made in bass breeding technology.

In the rearing of catfish, one of the challenges the farmer faces is high mortality rates for those using surface tanks (block ponds, plastic tanks, earthen ponds, etc.). Fish Mortality is usually highest when the fish is initially stocked during the fingerling stage (< 10g in size).  For farmers that purchase fingerlings, these losses can be crippling to their business and this article shows how to reduce these losses.

The water temperature requirements of various aquatic species in aquaculture, if you want to raise a fish well, you must know its characteristics, for example, what temperature is it suitable for? How much protein do I need to eat? Frequent outbreaks of disease? Temperature is important here, and knowing the optimum temperature for its growth can help improve feed utilization and reduce costs!

Seedlings are weakly disease-resistant and are infected with viruses or bacteria. Lead to diseases such as enteritis. The hematologic toxicity of ammonia nitrogen and nitrite killed the seedlings from hypoxia! From hatching to the steady growth of the seedlings. During this period, the small seedling’s resistance is relatively weak. In particular, the newly hatched seedlings are sensitive to dissolved oxygen, nitrogen, nitrite, bacteria and viruses, and temperature changes in the water.
