Electric shock of live fish can prolong transportation time
Aquaculture experts have found that electric shock to live fish, so that live fish fake death, can prolong the storage and transportation time. The method is to apply a voltage of 5000 volts per kilogram of live fish such as snapper for 30 seconds and make them breathe oxygen for 5 minutes. In this way, the fish will take the minimum breath necessary to maintain life and enter a state of suspended animation. The fish in this suspended animation state hardly need to consume oxygen, and can be kept and transported in the proportion of "half of the fish and half of the water", which can not only greatly save the transportation cost.

Breeding skills of clown fish
Algae-eating snails, five-claw shellfish and so on are the same as the artificial reproduction of nine-hole shellfish that we eat every day, when the gonads mature, we can use simple warming method or cooling method to stimulate them to release eggs and semen. First of all, take out the mature breeding shellfish, the female-to-male ratio is about 1:3, use the heater or ice cube to slowly rise or drop the water temperature for about 4 ℃, then rapidly cool or raise the temperature for 2 ℃, and then put it back into the original tank and return it to the room, where a large number of white smoky sperm and egg particles can be seen. There are slightly more females than males in most shellfish. Take nine-hole shellfish as an example.

Technique of main culture of freshwater Pomfret in shallow ponds
Among the existing ponds, shallow ponds still account for a large proportion. The water of this kind of pond is shallow, the drainage and irrigation is not matched, some are seasonally flooded into ponds, breed traditional fish, produce little fish, the benefit is very low. In order to explore the ways to increase production, increase income and increase efficiency of this kind of ponds, for two consecutive years from 1993 to 1994, we have a total area of 9.7 mu and a maximum water depth of 1. 5%. The experiment of main culture of freshwater Pomfret in shallow ponds was carried out in rice ponds, and satisfactory results were obtained in the absence of oxygen enrichment facilities: an average yield of 227 kg per mu in 1994.

Methods of preventing fish from anoxia in winter
In winter, although the intake of fish in the pond decreases, they still need a certain amount of dissolved oxygen to maintain slow breathing. The dissolved oxygen in the pond mainly comes from the photosynthesis of phytoplankton and the oxygen in the air dissolves directly into the water. However, in the cold winter, once the surface of the pond freezes, the oxygen in the air cannot dissolve in the fish pond. When heavy snow covers the ice, the sun cannot shine directly into the pond water, and the green plants in the water cannot carry out photosynthesis to produce oxygen. And most of the fish gather at the bottom in winter, if the water quality is poor,
