2. The feed for feeding Crispy Carp is mainly expensive natural northeast broad bean. Broad beans do not need to be crushed, and the whole material is 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. The nutritional components (water, crude protein, crude fat, crude ash, amino acids, calcium and phosphorus) in the muscles of crispy carp and common grass carp from the same farm were analyzed by biochemical analysis. Compared with other fish, the nutritional value of crispy carp and common grass carp was evaluated. The results showed that the nutritional components in the muscles of crispy carp and common grass carp were consistent in composition and content. The crude fat content is 65438 0.40% of that of common grass carp. The total amount of amino acids was higher than that of common grass carp, Monopterus albus, Siniperca chuatsi, Pelteobagrus fulvidraco, Wan 'an glass red carp, herring and bream, among which the content of glutamic acid was 3.93%, far exceeding the control fish.
1。 The water quality is fresh and the dissolved oxygen is sufficient, not less than 5 mg/L. It is best to use reservoirs, mountains and rivers. Swimming in turbulent water often exercises fish muscles and increases their toughness.

Crispy grass carp has strong adaptability to water temperature. In winter, it will go to the deep water area to escape. As long as the pond is dug deeper (more than 5 meters), it can still be cultivated. Because crispy pomfret generally grows in reservoirs with relatively fast water flow, where the water flow is very fast and strong, the meat quality of pomfret living there will become stronger than that of ordinary pomfret, so it tastes crisp.
