First of all, let's evaluate the idea of the landlord. Under the conditions of pond depth, stagnant water and exchangeable water, the idea of focusing on silver carp is very good, which can be described as low investment and high return.

Secondly, fish farming must provide bait. No matter what kind of fish are raised, silver carp can mainly rely on organic fertilizer and chemical fertilizer to cultivate plankton as bait.

3. Stocking quantity of fish species: silver carp 150, silver carp 100 per mu, mainly focusing on improving standards and pursuing benefits. Silver carp is best to be large, and 50-200g silver carp is more than half a catty. If grass carp does not provide exogenous bait, it is enough to put 20 per mu. Carp carp 300 -400 is enough.

Everything puts interests first.
