Bait feeding method for farmed hippocampus erectus

Abstract

The invention relates to a bait feeding method for farmed hippocampus erectus. During the farming period of the young hippocampus erectus, bait feeding is performed according to the following steps that before the body height of the young hippocampus erectus reaches 6.5 cm, copepods are fed to the young hippocampus erectus, wherein the feeding density is 15-20 pieces per milliliter; after the body height of the young hippocampus erectus reaches 6.5 cm, the copepods continue being fed to the young hippocampus erectus, wherein the feeding density is 15-20 pieces per milliliter; adult brine shrimps are fed to the young hippocampus erectus in an auxiliary mode, and the daily feeding amount accounts for 10 percent -12 percent of the weight of the young hippocampus erectus. According to the growth of the young hippocampus erectus, bait of different specifications is fed, and the two kinds of bait with different specifications and different nutritive values are mixed together for feeding; in this way, the feeding efficiency and feeding quality of the young hippocampus erectus can be guaranteed, and therefore cost of bait for the young hippocampus erectus during the stage of 6.5 cm-9.5 cm of the body length of the young hippocampus erectus is lowered by 50 percent; besides, maturing time can be shortened by about 9 days, so that energy consumption and labor cost are lowered, and the system utilization rate is increased. Accordingly, the bait feeding method has good application prospects.

Description

technical field [0001] The invention belongs to the field of seahorse breeding, in particular to a method for feeding gray seahorses with 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 breeding and breeding technology have made great progress, large-scale production t...

Problems solved by technology

Adult artemia or frozen mysis can be fed after the body height is 6.5 cm, but because of the low nutritional value of artemia, the effect of single-feeding adult artemia is relatively poor; although the effect of frozen mysis is better than that of adult artemia, but because the hippocampus eats dead bait The efficiency is low, it is easy to cause waste, and the price is high, which also makes it difficult to reduce the cost of bait
