Cultivation bait and technology for aquatic products

Abstract

The invention relates to cultivation bait and technology for aquatic products. The cultivation bait mainly comprises bean cake, wheat bran, fishbone meal and fly maggots. A preparation method of the cultivation bait includes: adding the bean cake and the wheat bran into fermentation broth in a fermentation tank to perform mixed anaerobic fermentation for 5-10 days; using Limin strains to ferment the fly maggots, and adding 10% of brown sugar at the same time, wherein the fermentation time is 3-5 days; mixing two fermentation products with the fishbone meal, and feeding aquatic products with the mixture every 9 hours, wherein average 0.5 ton of bait is applied to each mu, and the quantity is reduced by 1 / 3 in cloudy and rainy days. The bait is rich in nutritional substance, capable of increasing the survival rate of the aquatic products and capable of lowering cultivation cost.

Description

technical field [0001] The invention relates to aquatic product breeding bait and breeding technology. Background technique [0002] The current aquatic product breeding technology is relatively mature, and there are different choices of bait. Bean cake and wheat bran are the main components of bait, but the protein content is far from enough. my country consumes more than 900,000 tons of fishmeal each year, and needs to import about 800,000 tons. As the world's fish meal production has been decreasing in recent years, and consumption has gradually increased, the price has continued to rise, resulting in an increase in the cost of bait. The crude protein content of fly maggot powder is as high as 56%-63% (59.5% on average), 13% fat, 7% ash, and 3.1% sugar. As a high-protein feed, the nutritional level of fly maggots is comparable to that of the best imported Peruvian fish meal, 1.3 times that of bean cake and 1.9 times that of bone meal. The technology of utilizing fly ma...
