CATDOLL : CATDOLL: How to raise crayfish to grow fast and big How to make crayfish grow rapidly in a short period of time

1. Breeding density: Breeding density is an important factor affecting the size of crayfish. When the breeding density is high, the crayfish produced are generally smaller in size. When the breeding density is low, the crayfish produced per unit area are generally larger in size, with good appearance, clean surface, thin shell and more meat. An obvious example is that the seedlings released in the newly excavated shrimp fields are basically large crayfish with good appearance after growing up. Most of the crayfish from the old ponds are relatively small in size and poor in appearance. This is because there will be a lot of shrimp seedlings left in the old ponds, and the breeding density is relatively much higher.

2. Feeding: The reason why crayfish under artificial breeding conditions grow faster than those in the wild is that farmers feed them with sufficient bait and a relatively reasonable bait mix. Feeding soybeans and other baits on time every day ensures that the crayfish have sufficient and comprehensive nutritional intake. At the same time, algae and zooplankton are cultivated in the shrimp fields (ponds), and a large number of aquatic plants are transplanted. In this case, in addition to the artificially fed bait, crayfish also have a large amount of natural bait to eat, which ensures that they are full and eat well.

3. Smooth molting: As a crustacean, crayfish grows by molting repeatedly. So if you want crayfish to grow quickly, you must let them molt quickly and smoothly. Therefore, in the usual management process, you need to supplement calcium for crayfish. Generally, you can add some calcium-rich eggshell powder or bone meal to the bait you feed. At the same time, you also need to add an appropriate amount of molting hormone to the feed to speed up the molting of crayfish.
