Feed for preventing fin rots of sarcocheilichthys sinensis and preparation method thereof

Abstract

The invention relates to a fish feed, and particularly relates to a feed for preventing fin rots of sarcocheilichthys sinensis, and the invention further relates to a preparation method of the feed for preventing the fin rots of the sarcocheilichthys sinensis. The feed for preventing the fin rots of the sarcocheilichthys sinensis comprises the following components in parts by mass: 20 to 30 parts of fish meal, 8 to 15 parts of earthworm powder, 4 to 10 parts of squid powder, 6 to 12 parts of rice bran, 3 to 7 parts of houttuynia cordata, 3 to 8 parts of honeysuckle, 2 to 6 parts of radix clematidis, 3 to 7 parts of cassia twig, 2 to 5 parts of grapefruit, 2 to 6 parts of aster, 1 to 5 parts of asparagus cochinchinensis, 1 to 4 parts of cuttle bone, 2 to 6 parts of purple perilla, 1 to 4 parts of purslane, 1 to 4 parts of olive oil and 1 to 4 parts of compound vitamin. The feed for preventing the fin rots of the sarcocheilichthys sinensis is provided according to energy metabolism modes and nutritional requirements of the sarcocheilichthys sinensis; after the sarcocheilichthys sinensis is fed, the feed coefficient is low, the specific growth rate is high, and the superficial ulcer resistant capability is strong.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for preventing fin rot disease of Chinese carp; the invention also relates to a preparation method of the feed for preventing fin rot disease of Chinese carp. Background technique [0002] Chinese squid, long body, flat side, protruding head and back, round abdomen. The head is short. The kiss is slightly protruding, and the front end is round. Mouth small, inferior, slightly horseshoe-shaped. The lip is slightly thick, the lower lip is limited to the corner of the mouth, and the posterior lip groove is interrupted, and the interlayer is widely separated. The anterior edge of the mandible has a well-developed horny edge. The mouth and mouth have whiskers 1 pair, shorter, thin and weak. The gill rakers are short and sparsely arranged. Hypopharyngeal teeth slightly compressed laterally, with hooked ends of first and second teeth. The outer edge of the dorsal fin is slightly truncated, t...

Problems solved by technology

[0003] At present, during the cultivation process of Chinese squid, due to continuous fertilization and bait feeding, the remaining feces and residual bait are most likely to damage the water quality, which often causes fin rot in squid. When people deal with fish diseases, they often use according to the condition. The method of splashing sterilizing and disinfecting agents, but the drugs will more or less produce side effects or toxicity. Although they can kill the pathogenic bacteria on the surface of the Chinese carp and in the water, they often cause water pollution, and long-term use will cause the accumulation of drugs and affect Body health, which in turn affects the growth rate of Chinese squid

In the growth process of Chinese squid, lack of nutrition often leads to insufficient resistance and fin rot disease on the body surface, which affects the survival rate of squid. The Chinese squid compound feed that is beneficial to the growth and development of the squid is an urgent problem to be solved in the current squid breeding industry
