Strengthen the management of greenhouse fish
To strengthen the management of greenhouse fish at present, tilapia, catfish, freshwater Pomfret seedlings and adult fish culture tilapia are mainly farmed in the greenhouse. Attention should be paid to the maintenance of water temperature and water quality management to prevent the sale of frostbite in the head. Chlorine dioxide can be used for water disinfection at ordinary times, and high-protein full-price particles should be selected as far as possible. When breeding bearded catfish, chlorine dioxide can also be used to disinfect the water. It is worth paying special attention to prevent the occurrence of skin rot, and pay attention to keeping the bait fresh when feeding chicken intestines and other animal scraps.

Three measures for high yield and high efficiency of fishery
In order to obtain high yield and high efficiency of fishery, the ecological conditions of aquaculture should be actively optimized and the construction of pond facilities should be strengthened. We can start from the following three aspects. 1. In order to carry out the Laotang reconstruction project, the main projects should be carried out in accordance with the requirements of "ecological, circular, healthy and intensive", such as "dredging depth, pond shape transformation, pond embankment slope protection, pond ridge widening and arrangement, and no matching improvement of water, electricity and road". In particular, the thick layer of silt at the bottom of the pond should be removed so that the sediment can be reduced to about 20 cm. By dredging

Pay attention to the breeding of fish in autumn
Adjust the density, graded feeding into the autumn can choose the appropriate weather where the temperature is relatively cool, and screen the uneven fish species in the pond and classify them according to large (about 20 cm), medium (about 15 cm) and small (less than 15 cm). Large-sized fish species can be transferred to adult ponds with larger area and better conditions, and medium-and small-sized fish species can be farmed in separate ponds. The stocking density is generally about 15 meters in the pond with a depth of about 3000 Mu. Fertilize according to the water, feed reasonably the breeding ponds mainly composed of silver carp and bighead carp, except

There are five ways to kill the beetle.
The larvae of beetles, commonly known as chicken dung insects, gnaw on the roots of seedlings, in addition to biting lateral roots and main roots, but also can peel off the root skin, resulting in lack of seedlings and broken strips, and in serious cases, it will also cause devastating disasters. Adult beetles like to eat both leaves and flowers, and the reproduction speed is very fast, which is easy to cause harm to seedlings, and is a common major pest in forestry. The time of rampant adult damage is about June to October, which is the best period of control, that is, to control the adult damage and the population density of the next generation, we will get twice the result with half the effort.

Prevention and treatment of protozoan disease of large yellow croaker Pseudosciaena Crocea
(1) pathogen stimulates cryptosporidium (Crypjocaryonirrions). (2) there are small white spots on the body surface and gills of symptomatic diseased fish. These white spots are white vesicles formed by parasitic parasitism, host stimulation, secretion of large amounts of mucus from surrounding tissues and proliferation of epidermal cells. If the disease is serious, the body surface tissue is destroyed. If bacteria invade, it can cause skin inflammation, scale exfoliation, fin membrane decay, split, corneal damage and blindness.
