Abstract

The invention belongs to the technical field of marine fish (mullet) bait research and development, relates to a treatment method and a component proportion of high-efficiency marine algae enteromorpha for baits, and aims at using enteromorpha as a new feed resource for development and application and applying the enteromorpha as a low-input high-output algae feed in the breeding industry. The marine green tide algae enteromorpha serving as a high-efficiency feed additive comprises the following components: 300g of fish meal, 300g of soybean meal, 70g of whole wheat flour, 50g of yeast, 50mL of maize germ oil, 15g of soybean lecithin, 5g of sodium alginate, 1g of cellulase, 50000IU of vitamin A, 4000IU of vitamin D, 100mg of vitamin E, 50mg of vitamin B1, 50mg of vitamin B2, 5mg of vitamin B6, 10mu g of vitamin B12, 150mg of nicotinamide, 50mg of calcium pantothenate, 500mg of choline bitartrate, 500mg of vitamin C, 100mg of iron, 10mg of copper, 5mg of zinc, 10mg of magnesium, 1mg of iodine, 10mg of manganese, 100mg of potassium, 5580mg of calcium hydrophosphate, and 250mg of L-lysiante, wherein the enteromorpha is added according to a gradient. A feeding attraction activity test is carried out by detecting the rate of live weight growth of mullet, a specific growth rate and a bait coefficient, and the best feed enteromorpha gradient is finally determined. According to the invention, the enteromorpha serving as a low-cost high-efficiency feed additive can be quickly applied in the breeding industry.

Description

technical field [0001] The invention belongs to the technical field of marine fish (barracuda) bait research and development. The invention relates to a treatment method and composition ratio of high-efficiency marine alga Enteromorpha for bait. The invention aims to develop and apply Enteromorpha as a new feed resource, and use it as an algae feed with low input and high output for aquaculture. Background technique [0002] At present, China's seaweed industry is mainly concentrated in health food and industrial rubber extraction. In terms of feed processing, some common seaweed feeds are fed to poultry. In livestock experiments, they have achieved good results in disease resistance and production increase. However, the harmful green tide algae Enteromorpha It is rarely used effectively, and it is rarely used as a feed additive in fish farming. Therefore, the research on the green tide seaweed Enteromorpha aquatic feed is progressing slowly. From the research on other alga...
