Fish bait feeding method for hippocampus erectus adults

Abstract

The invention relates to a fish bait feeding method for hippocampus erectus adults, which comprises the followings: bait feeding to hippocampus erectus is performed under the condition of an allocating culture system and breeding environment. The method specifically comprises the followings: A, normal cultivation period: water temperature is controlled within 25 to 28 DEG C, artificial light is adopted for prolonging photoperiod for 0.5 to 1 hour before sunrise and after sunset, bait is fed according to 12 to 15 percent of weight, and feeding is performed for three times respectively; siphon of manure and residuary bait are respectively performed; and B, overwintering period: water temperature is controlled within 22 to 23 DEG C, artificial light is adopted for prolonging the photoperiod for 0.5 to 1 hour before sunrise and after sunset, bait is feed according to 8 to 10 percent of weight and feeding is performed for three times respectively; and siphon of manure and residue bait are respectively performed. According to the invention, artificial light is adopted for prolonging photoperiod, defecation of hippocampus is accelerated, the opportunities of water pollution and the accessions of gas disease are reduced, and the sickness rate of gas disease of hippocampus is generally lower than 5 percent. Therefore, the survival rate is increased and the application prospect is excellent.

Description

technical field [0001] The invention belongs to the field of feeding seahorse bait, in particular to a method for feeding gray seahorse adult fish bait. Background technique [0002] Hippocampus is a traditional Chinese medicine. According to statistics, more than 200 tons of dried medicinal products are used in my country every year. As my country's natural resources are nearly exhausted, most of the hippocampus needed in the market is imported, and the price has been increasing year by year. The average price has exceeded 4,000 yuan per kilogram. Calculated by importing 200 tons per year, the value exceeds 800 million yuan. Because the natural resources of seahorses have been severely damaged, many countries in the world have carried out artificial breeding research in order to restore resources. As early as 1957, my country launched seahorse breeding research. Fifty years later, although seedling technology has developed, large-scale production technology has not yet ac...
