The optimum protein level of fish feed
Protein is the main nutritional index of compound feed for fish. the level of protein directly affects the internal quality of fish feed. The optimal protein requirements of different fish species and growth stages are also different. Too high protein content will not only cause a waste of feed protein resources, but also increase the pressure on pond water quality management. If the protein content is too low, it will cause slow growth and poor disease resistance of fish on the one hand, and delay production on the other hand. Therefore, mastering the optimal protein level of fish feed is very important to guide fishery production.

Three key links of cultivating mushrooms in high temperature season
In order to cultivate mushrooms well in the high temperature season, we need to grasp three technical links. First, select suitable high-temperature strains. At present, the more heat-tolerant mushroom strains are Xincheng 96, Su Mushroom No.1 and so on. Among them, the temperature of Xincheng 96 was 36 ℃, and the optimum temperature was 33 ℃. The temperature of mushroom production is 20-36 ℃, and the optimum temperature of mushroom production is 24 ℃. It is the most heat-tolerant strain at present. The greatest advantage of this strain is that the mushroom harvested 2 million mdashent3.

Introduction of excellent varieties of Pleurotus ostreatus
According to the different temperature requirements in the period of fruiting body differentiation, Pleurotus ostreatus was divided into four groups, namely, low temperature type, medium temperature type, high temperature type and wide temperature type. In low temperature type, the optimum temperature for fruiting body differentiation was 10-15 ℃, such as Pleurotus ostreatus, Pleurotus ostreatus, Jingzhou No. 1, Suping 48, 4011. In the medium temperature type, the optimum temperature for fruiting body differentiation was 16-22 ℃, such as Pleurotus ostreatus and Pleurotus ostreatus. In high temperature type, the optimum temperature for fruiting body differentiation was 22 ~ 26 ℃, such as Pleurotus ostreatus, Pleurotus ostreatus, Suping 1.

What is the relationship between the culture of the four major domestic fish and meteorological conditions
Fish live in water, but it is also closely related to meteorological conditions. Temperature fish is a variable temperature animal, the water temperature is the body temperature, the water temperature directly affects the metabolic activity of life, the optimum temperature range is 10 to 33 degrees Celsius, the optimum temperature is 25 to 30 degrees Celsius, the optimum temperature is 25 to 30 degrees Celsius, and the dormancy begins below 10 degrees Celsius. Slow growth, increased appetite at 15 to 20 degrees Celsius, fast growth, the fastest growth at 20 to 30 degrees Celsius, and slow growth above 30 degrees Celsius, so bait intake should be paid attention to.
