Abstract

The invention discloses feed for breeding early young crabs of river crabs. The feed is characterized by being composed of the following components in parts by weight: 70 parts of fine-grained bean cakes, 30 parts of wheat bran, 20 parts of fermented soybean curb residues, 15-25 parts of water hyacinth powder, 8-12 parts of monodus subterraneus, 5-8 parts of ganoderma cultivation bacterium residues, 3-7 parts of methionine, 1-3 parts of choline chloride, 3-5 parts of salt and 5-7 parts of calcium hydrophosphate. The feed for breeding early young crabs of river crabs provided by the invention is scientific and reasonable in component preparation, rich in nutritive value, low in cost, convenient for eating of the early young crabs and excellent in absorption, the nutritional requirements during growth are met, and the meat quality of grown-up young crabs can be ensured while enabling the young crabs to rapidly grow.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding feed for early young crabs of river crabs. Background technique [0002] River crabs are also called "crabs" and "hair crabs". The carapace formed by the combination of the head and the chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; behind the chelicerae, there are 4 pairs of walking legs, with flat sides and longer; the abdominal limbs have degenerated. The male and female of the river crab can be distinguished from its abdomen: the abdomen of the female is round, and the abdomen of the male is triangular. The river crab is a large crustacean with a body divided into 21 segments. Since the head and thorax segments are healed with each other, the whole body is divided into two parts...
