1. Aquaculture Aquaculture is selected for cage culture and the requirements for water types are not limited. It can be a pond, a river, a lake, or a reservoir. However, the general requirement is that the water source is guaranteed and the water quality is pollution-free. Water source water quality standards must comply with GB11607-1989 Fishery Water Quality Standards. Ponds generally require an area of ​​more than 3 acres and a water depth of more than 1.5 meters. The injection and drainage are convenient and the drainage channels can be separated. Dashui surface water body should try to choose the open water, slow flow, small wind and waves, quiet environment, sunny bay, lake, and avoid the main channel, the water depth of 2-4 meters, flat bottom, sediment less water for breeding.
Second, cage structure and settings
1. The cage structure is made of polyethylene non-nodular mesh sheets with a mesh size of 20-40 mesh. The specifications of the cages are mainly 2m 3m, 2m 4m and 3m 4m. The height of the box is 1.2-1.5m, rectangular and open type.
2. Net cages The cages are usually arranged in a single row or in multiple rows. Each column is separated by 1-2 meters. The distance between cages is 1-2 meters. The upper edge of the cage is 40-50 cm above the water surface. Ponds and other small water bodies are provided with fixed cages. The cages are fixed with bamboo frames. The cages in large water surfaces are lifted to facilitate lifting and cleaning of the cages as the water level changes. The density of cages in ponds generally accounts for about 60% of the pond's water area. Depending on the exchange of water, the general principle is not to exceed the self-purification capacity of the water body.
三ã€Preparatory work before stocking
1. Soak net cages. Newly prepared cages should be soaked in water for 5-7 days before being stocked.
2. Set the aquatic plants in cages generally 3-5 days prior to stocking. Place aquatic plants in cages. Water peanuts are more suitable. Coverage area should account for 80% of cage area. Water peanuts cannot exceed the net. Box mouth, to prevent the species to escape. Into the box of water peanuts should be washed, and after disinfection, generally with 10 g / cubic meter of bleach or 5 g / cubic meter of chlorine dioxide soak for 5-10 minutes to prevent aquatic plants carrying pests and insects Eggs enter the cage.
3, pond preparation In the pond to engage in cage culture, it is necessary to remove excess silt in the pond in advance, and then use quicklime 150 kg / mu to disinfect, in order to kill the pond of harmful bacteria, eggs, and improve the substrate. After the ponds are filled with water, the cages are well-placed and the water in the cages is placed. The entire pool is then sterilized and 0.30.5 g/m3 of bromochloroheine can be used for the Quanchiposa. Wait until the disappearance of the medicinal properties, and the grasses in the cage have returned to green before they can stock their seedlings.
Fourth, the kind of delivery
1. The source and selection of seedlings mainly comes from the purchase of natural wild seedlings harvested by hand. In general, the grazing species are better, and their survival rate is higher. The species should be selected for deep yellow, no lesions, no trauma, mucus is rich, strong activity of the giant beak, and the back of the Qing gray, black, slender body shape, head and tail of small inferior species are not suitable for cage culture. The stocking specifications are based on 20-30 tails/kg.
2. Restocking time and stocking density The seedlings are usually put in the 4-9 months of each year, and the best time is 4-5 months. At this time, the weather turns from cool to warm, the rain is abundant, the wild seed is abundant, and the price is low. It is mainly based on cages and has a high survival rate. The stocking density is generally 2.5-3 kg/m3, which should be based on the water source and feed supply conditions. Generally, the type of clams to be stocked should be the same size and should be sufficient at one time. Seedlings should be disinfected prior to seedlings.
V. Feeding management
1. No feed was given within 3 days after the feed was fed into the box, and feeding and domestication started after 3 days. During domestication, 1-2 food stations can be set in the cage to facilitate spot-induced food intake. After 7-10 days of domestication, the squid began to concentrate on food intake. Mackerel bait can be divided into two categories: one is animal feed, such as small fish, clams, snails, clam meat, shrimp, and the other is artificial compound feed (protein content is about 40%). The specific use of feed, should be based on the local feed resources and choose to feed the food. Feed feeding should be carried out in accordance with the "Four Sets" requirements. In other words, the water temperature is fed twice a day in the optimum temperature range of the Astragalus membranaceus, which is 8-9 am and 6-7 pm respectively. Positioning, bait should adhere to feeding on a fixed food table to reduce the loss, to facilitate the observation of the ingestion of astragalus and the removal of debris. Qualitative, requiring bait fresh and not deteriorated. Quantitatively, under normal circumstances, the pelleted feed is fed with about 3% of the body weight of Astragalus per day. When fed with a fresh feed, the daily feeding amount accounts for about 6% of Astragalus. The total amount of feeding is better when there is no residual bait in the net during the second feeding.
2. Water quality regulation Maintaining fresh water in the Dianchi Lake and adequate dissolved oxygen are the key to success. In particular, during the summer hot season, the water quality of the pond's small water bodies is easily deteriorated, and the water quality of the pond water must be adjusted. The adjustment method is mainly to change the water, drain the old water in the pond and add new water. If necessary, use water quality improver, such as regular sprinkling of quicklime, about 10 kilograms per mu of water surface dosage, in the cage regularly apply or add microbial agents in the feed, in order to achieve the purpose of improving water quality.
3, daily management insist on checking the cage regularly for damage, often cleaning the cage, keep the exchange of water bodies inside and outside the body open, on the water surface culture area, pay attention to the water level changes, timely adjustment of the cage position and reinforcement cages, while doing Good day-to-day management diary, such as daily water temperature, temperature, transparency, pH value, feeding amount, and the presence or absence of abnormalities during the feeding period, in order to continuously summarize the culture experiments and raise the level of culture.

The so-called plant-based is the substitution of plant protein for animal protein food grade applications. Plant-based ingredients protein products come from plants such as soy, wheat and peas. That is pea protein powder, soy protein powder, pumpkin protein and so on. The plant protein application category includes protein drinks, dairy substitutes, meat substitutes, protein bars, nutritional supplements, processed meat, poultry and seafood, baking, food and sports nutrition products. Plant protein applications enhance the nutritional and functional properties of products, such as texture, emulsifying properties, solubility, stability and adhesion.
