From July to September in summer, although the temperature is high, the water temperature is suitable for the growth of fish, which is the peak season for the growth of fish, but also the high incidence of fish disease, so we should not only pay attention to feeding, but also to the prevention and control of fish disease:

Protein by sources of raw materials can be divided into two major categories of animal protein and vegetable protein

With the continuous development of feed industry, the nutritional composition of compound feed is becoming more and more complex, which changes the original flavor of feed and affects the feed intake of fish, and seasoning is an effective measure to solve the palatability of feed.

1. Container

The container for raising fish should reach more than 30 cm. The bigger the fish, the bigger the fish tank is. The large fish need a covered aquarium to avoid the occurrence of jumping out of the tank.

Tilapia are tropical fish that are not resistant to low temperature and will gradually die when the water temperature drops below 12°C.

Maintaining good water quality can stimulate the appetite of tilapia, reduce the feed coefficient, and improve the growth rate of fish. In the early stage of breeding, in order to save costs, the use of fertilizer water culture.

Choose a place with good water source, fresh water quality, no industrial pollution, good soil quality and convenient transportation to build a pool.

. The nutritional effect of bile acids on crustaceans: Crustaceans (especially shrimp) cannot synthesize cholesterol and bile acids, and they need to ingest cholesterol and bile acids at all stages of growth.

Aquaculture may seem simple, but it actually contains a lot of knowledge.

Whether or not chicken manure is disposed of is related to environmental safety, while the method of disposal is related to economic benefits.

The heavy metal elements polluting animal-derived feed products mainly include lead, arsenic, cadmium, chromium and mercury.

The heat treatment of feed is to add a certain pressure of steam to the material or through a mechanical method, so that the material absorbs a certain amount of water and heat in a short time to generate a large temperature rise, so that the material is in the temperature, pressure, humidity.
