The feed of crisp pomfret is mainly broad beans. Broad beans do not need to be crushed, and the whole beans are soaked in clear water for more than one day and night to make them soft and swollen, which is convenient for grass carp to eat and digest. According to the quantity and specifications of Siniperca chuatsi in the pond, it is fed in a certain proportion (feed coefficient is about 5%). However, the price of broad beans is high, so it is not cost-effective to use them in the whole process of breeding. In order to reduce the cost of breeding, grass carp is generally raised to a weight of more than 1 kg by conventional methods in production, and then fed with broad beans for more than 3 months in a running pool, so that the cost of raising crispy pomfret is low and the special flavor of crispy pomfret can be maintained. At present, the market situation is that crispy pomfret with large size and over 3.5 kg is more popular.
