Feed formula for improving water quality of blue crab aquaculture pond

Abstract

The invention belongs to the technical field of feed formulas and relates to a feed formula for improving water quality of a blue crab aquaculture pond. The feed formula is prepared from the following raw materials in percentage by weight: 24% of fish meal, 29% of soybean meal, 4% of chicken meal, 6% of vegetable meal, 25% of flour, 1% of beer yeast, 0.2% of tapioca flour, 0.2% of choline chloride, 0.1% of bentonite, 1.5% of calcium hydrophosphate, 0.6% of lysine, 0.2% of methionine, 1% of a functional nutrition additive, 1.5% of vitamin and mineral premix and 5.7% of fish oil. The feed is simple to prepare, low in cost, high in bait utilization rate and free of water pollution.

Description

Technical field[0001]The present invention relates to the field of feed formulation, and more particularly to a feed formula for improving the water quality of blue crab breeding pond.Background technique[0002]Scylla Paramamosain is affiliated to the sage, Shi Fei, Short Tail, Surface Cancer, Blue Cancer, is widely distributed in my country Zhejiang, Fujian, Guangxi and other provinces, is the main marine economic crab in the southeast coast of my country. One. Blue crabs have become the main cultured crabs in the three gates of Taizhou due to short growth rates, short breeding cycle, high economic efficiency. During the traditional culture of blue crabs, the bait and the fresh fish and ice fishing of seawater fishing were mainly funded, and the utilization efficiency of bait was low, the breeding cost was high, and the water pollution was severe.[0003]Water pollution is mainly part of the fish feeding in the breeding process, partially deposited in the water body. Since the bait is...

AI Technical Summary

Problems solved by technology

Because the bait is rich in protein, it will produce a large amount of nitrogen and phosphorus pollution, resulting in eutrophication of the water body
