How to prevent fish from oxygen deprivation in winter? These practical methods you need to master
In winter, although the feeding activity of fish in ponds decreases, they still need a certain amount of dissolved oxygen to maintain slow breathing. The dissolved oxygen in a pond mainly comes from the photosynthesis of phytoplankton and the direct dissolution of oxygen from the air into the water. However, in the cold winter, once the pond surface freezes over, oxygen from the air cannot dissolve into the fish pond. When heavy snow covers the ice surface, sunlight cannot shine directly into the pond water, and the green plants in the water cannot carry out photosynthesis to produce oxygen. Moreover, in winter most fish gather at the bottom of the water. If the water quality is poor, the fish are weak, and management is poor, it can easily cause fish to suffocate and die from lack of oxygen.

Clownfish Breeding Techniques and Methods Explained in Detail
Turban snails, five-claw scallops and the like, just like the abalone (jiukong shellfish) we commonly eat, can be artificially bred: when the gonads are mature, a simple method of raising or lowering the temperature can be applied to stimulate them to release eggs and sperm. First take out the mature broodstock, with a male-to-female ratio of about 1:3, use a heater or ice cubes to slowly raise or lower the water temperature by about 4°C, then rapidly lower or raise it by 2°C, then place them back in the original tank to return to room temperature, and a large amount of white smoke-like sperm and egg granules can be seen being released. In most shellfish, females slightly outnumber males. Taking the abalone as an example,

Electric shocks to live fish can effectively extend transport time
Fisheries experts have found that giving live fish electric shocks to induce a state of suspended animation can extend storage and transport time. The method is to apply a voltage of 5000 volts to each kilogram of live fish such as sea bream for 30 seconds, then let them breathe oxygen for 5 minutes. In this way, the fish carry out the minimal breathing necessary to sustain life and enter a state of suspended animation. Fish in this state of suspended animation consume almost no oxygen and can be stored and transported at a ratio of "half fish, half water," which not only greatly saves on transport costs,
