1. Classification of fish
carnivorous fish: such as catfish, bighead carp;
omnivorous: carp, crucian carp, tilapia, etc.;
herbivorous: grass carp;
filter feeding: silver carp, bighead carp.

2.adaptive water temperature
According to the fish adapt to the water temperature can be divided into the following categories tropical fish, warm water fish and cold water fish.
Tropical fish: generally adapted to the low water temperature of about 10℃, If tilapia begins to die when the water temperature drops to 12℃, A maximum temperature of 40℃, The adaptive temperature is 16~40℃, The optimum temperature is 28~32℃.
Warm water fish: adapt to water temperature of 0~32℃, Like carp, And when the water reaches 10℃, The optimum growth water temperature is 24~30℃.
Cold water fish: adapt to the water temperature line around 20℃, When the temperature is 4~20℃, The optimum growth temperature is 12~18℃, And when the water's over 24℃, Easy to die.

3.The selection of fish feed pellet
We feed pigs, cattle, chickens, ducks and fish daily, usually forage, single powder, pulp feed or cereals. Later, some powdered feed was mixed evenly in a certain proportion to become powdered mixed feed. Granular feed is based on the nutrition needed by different feeding objects, using different raw material formulations, after crushing, mixing, drawing and other processes, to make particles of different sizes and shapes.
