Culture conditions of baby fish

Whether the artificial culture of baby fish can be successful, the culture environment is very important.

1. The aquaculture water temperature should be suitable. According to years of observation, the most suitable water temperature for the growth of baby fish is 16-22 ℃. In the low mountains, the summer temperature is higher, if the water temperature exceeds 26 ℃, the growth of baby fish will be affected, sometimes there will be "summer dormancy" phenomenon, too high temperature will also lead to the death of baby fish; but if the altitude is too high, the ambient temperature and water temperature is too low, the effective growth time of baby fish is short, the growth rate is slow, and culture is not cost-effective. Therefore, for raising baby fish, it is best to choose an area with an altitude of 500 to 800 meters above sea level and where there is no severe cold in winter and no heat in summer.

two。 The water quality of aquaculture is better. Baby fish like to be clean and afraid of dirt, and they have very strict requirements on the water quality of their environment. Wild baby fish generally live in deep mountains, valleys and rivers where natural vegetation is good, the environment is pollution-free, and human beings rarely set foot in. For artificial breeding of baby fish in mountainous areas, it is best to choose small stream ditches and springs with perennial running water, and you can also use the bottom water of large and medium-sized reservoirs with fresh water quality. in short, the water quality should be fresh, fresh, pollution-free, high dissolved oxygen and neutral PH value. Some of the chemicals from mountain farmland, mines and urban tap water may exceed the standard and cannot be used as water for baby fish culture.

3. The breeding environment should be quiet. Baby fish have the habit of being quiet and afraid of fear, and being afraid of chicken in yin, so a quiet environment is very important for raising baby fish. To build doll fish farms in mountainous areas, it is best to choose places surrounded by mountains, luxuriant trees, sparsely populated, relatively independent, quiet and shady environment, and do appropriate cover. Some farmers use natural rock caves, or artificially dig tunnels where there is water, which can not only maintain constant temperature, avoid light, quiet, but also prevent escape and theft, and the breeding effect is very good.

In order to meet the above conditions, it is best to choose a suitable environment to build a farm in the place of origin of baby fish. In addition, the mountain area is prone to sudden floods in summer, so we should also do a good job of preventing erosion and escape when building the site.
