Principles of fish health management

The concept of fish health management is that fish culture under such conditions will achieve the best growth rate, feed conversion rate, reproduction rate and survival rate. It is very important to maintain a high-quality water environment and feed with balanced nutrients to maintain the health of fish and prevent them from getting sick. Proper fish health management should aim at environmental, nutritional, economic and other factors to prevent fish diseases rather than focus on the treatment of fish diseases.

Main technical measures for mixed culture of fish and soft-shelled turtle

1. Pond transformation: Build a 30 cm high escape wall around the pond. The four corners are arc-shaped. The inner wall is smooth with cement. It is best to have a "factory" shaped edge on the top of the wall to prevent the old turtle from escaping. Bamboo rafts are set up in the fish pond as sunbeds for old turtles to sunbathe their backs, so there is no need to add necessary equipment such as food tables. 2. Filter-feeding fish, omnivorous fish and herbivorous fish feeding plankton can be mixed with old soft-shelled turtle in the same pond, but black carp should not be put into the mixed pond. 3. Reasonable stocking density of old soft-shelled turtle

Puffing floating material has many advantages in breeding four major domestic fish

The culture of grass carp with puffing floating water complete feed has many advantages such as low cost, high utilization rate and protection of culture water environment. In the United States, Japan and other countries with developed aquaculture technology, floating aquatic feed has been widely used since the 1980s to meet the needs of environment and fishery production. In recent years, China has also vigorously promoted the use of floating aquatic feeds, which has developed rapidly. Many famous and excellent aquatic species have been used in large quantities, but the use of expanded floating fish feeds for breeding four major domestic fish has not been successful.

First, fishing time to determine the appropriate time to catch crabs is a key to improve the efficiency of raising crabs, neither too early nor too late. Too early will affect the growth of the river crab, is not conducive to the increase of yield; too late, the river crab will escape after sexual maturity, resulting in losses. The appropriate fishing time should be from the source of river crab and stocking rules.

Fish skin trematodes (the third generation of worm gyrodaclylus sp.)

Infection details skin trematodes are trematodes up to 0.8 mm in length. They attach themselves to the fish's skin (occasionally to the gills) through a sucker with two hooks in the center, and feed on skin cells. At low

Six conditions affect the feeding of fish

In the process of intensive fishery production, the management of feed feeding is one of the main links in the whole production management, and the decrease of feed intake of fish often occurs in the process of feed feeding. According to the different conditions in the production, the reasons for the decrease of feed intake of farmed fish are as follows: the first situation: the fish is suffering from the disease, which leads to the decrease of feed intake of fish. Such as Carassius auratus endosporidiosis, grass carp three diseases, spotted forktail disease, enteritis and other diseases, the food intake of fish decreased significantly.

The storage of the queen bee

There are two ways of storage: in-group storage and out-of-nest storage. The main results are as follows: (1) it is most convenient to store queen bees in mating colony. When the new queen bee in the mating group begins to lay eggs for a week or so, it is locked in a rectangular iron gauze platform and embedded in the spleen of the mating group. At the same time, it lures the group into a mature king platform. A similar method can be used to store the queen bee in the relay box of the strong group.
