Embodiment 1

[0020] First, carry out the substitution ratio experiment in the laboratory: replace 1%, 5%, 10%, and 15% fish meal in the commercial feed (commercial feed) with cotton meal and soybean meal respectively, and formulate the feed according to the following formula.

[0021] Control group river crab is fed with commercial feed (commercial feed), and the prescription of described commercial feed is: fish meal 35%, soybean meal 30%, cornstarch 21%, fish oil 1.4%, soybean oil 2.4%, soybean lecithin 0.5%, Cholesterol 0.5%, multidimensional 3%, multimineral 2%, choline chloride 0.5%, binder 2%, bran 1.7%.

[0022] The formula of the feed fed by the crabs in the 1% replacement group was: 34% fish meal, 30% soybean meal, 1% cotton meal, 21% corn starch, 1.4% fish oil, 2.4% soybean oil, 0.5% soybean lecithin, 0.5% cholesterol, Multidimensional 3%, Multimineral 2%, Choline Chloride 0.5%, Adhesive 2%, Bran 1.7%.

[0023] The formula of the feed fed by the crabs in the 5% replacement group...

Embodiment 2

[0043] Control group: the feed still adopts the existing river crab commercial feed in Example 1.

[0044] Test group: adopt the river crab feed of the present invention, and use cotton meal and soybean meal to replace part of the fish meal in the above-mentioned existing river crab feed to carry out river crab feeding. The composition of the used crab feed of the present invention is as follows: 25% of fish meal, 35% of soybean meal, 5% of cotton meal, 21% of cornstarch, 1.4% of fish oil, 2.4% of soybean oil, 0.5% of soybean lecithin, 0.5% of cholesterol, multidimensional 3 %, polymineral 2%, choline chloride 0.5%, binder 2%, bran 1.7%.

[0045] Other steps and the composition of multi-dimensional and multi-mineral are identical with embodiment one. Experimental statistics, such as Figure 5 As shown, compared with the control group, the male crabs and female crabs fed with the feed of the present invention have no significant difference in weight gain.
