Use of protein-enriched aquatic feed

Abstract

The invention discloses use of a protein-enriched aquatic feed. The aquatic feed adopts fish meal and yellow mealworm meal as high-protein feed sources and further contains squid powder, vital gluten,linoleic acid, calcium dihydrogen phosphate, a feed additive, a premix, a binder and a Chinese herbal medicine extract. The aquatic feed is scientific in proportion and contains complete nutrients; and the Chinese herbal medicine extract is prepared through microwave extraction and organic solvent sedimentation treatment. The aquatic feed provided by the invention is rich in proteins, and feed particles have good stability and excellent palatability and food-calling property; the preparation method has the advantages of high rate of finished products, high formation speed of particles and production efficiency and low production energy consumption; and the aquatic feed is capable of promoting the growth and development of aquatic animals, enhancing the immunity and improving the meat quality of the aquatic products after being applied to the aquaculture.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to the application of a protein-rich aquatic feed. technical background [0002] With the rapid development of aquaculture in my country, the proportion of aquaculture in the aquaculture industry is increasing continuously. Due to the continuous expansion of market demand, the breeding density of aquaculture farmers is also increasing. The increase in breeding density has accelerated the cycle of water quality aging and water quality deterioration. The first is the pollution of the aquaculture water environment: Due to the abuse of clear pond disinfectants, insecticides, random sewage discharge at the bottom of high ponds, and biological pollution of offshore red tides, some water quality problems in the seawater included in the aquaculture pond or the surface well water extracted in recent years have been affected. Indicators such as beneficial microorganisms, algae species, water hardn...

Increased breeding density speeds up the cycle of water quality aging and water quality deterioration

The first is the pollution of the aquaculture water environment: Due to the abuse of clear pond disinfectants, insecticides, random sewage discharge at the bottom of high ponds, and biological pollution of offshore red tides, some water quality problems in the seawater included in the aquaculture pond or the surface well water extracted in recent years have been affected. Indicators such as beneficial microorganisms, algae species, water hardness and alkalinity, and heavy metal indicators are increasingly unsuitable for the growth of algae. It is difficult for beneficial algae to reproduce as a population advantage, resulting in difficulties in fertilization and water.

The second is the aging and acidification of the bottom of old earth ponds: After nearly ten years of development and breeding, most of the bottoms of earth ponds have been seriously acidified, the bottom mud is highly viscous, acidic, hardened, and the exchange of sediment nutrients and water energy and substances stagnates, resulting in algae It is difficult to continuously absorb balanced nutrients, resulting in unstable algae phase, easy to clear water, moss on the bottom of the pool, and the reverse side of the mud skin, etc.

Third, there is a mixed bag of fertilizer and aquatic products in the market. There is no clear industry production and use standards, and no clear ideas for product promotion and use; The fertilizer and water given to shrimp by compound fertilizer is the cause of the imbalance of algae and bacteria, and the difficulty of cultivating beneficial algae into dominant populations

In terms of animal feeding, the use of antibiotics and hormones as feed additives once played an important role in improving animal production capacity, but there are many disadvantages in large-scale use, such as causing the imbalance of normal gastrointestinal flora, reducing the level of immune function, and causing pathogens. Microbes develop drug resistance and drug residues in aquatic products, thereby threatening human health and causing environmental pollution, etc.
