No matter what kind of fish you raise, you must have a fish tank. According to the size of the fish you catch, you must choose a tank with appropriate specifications. If the tank is too small, the fish will not be able to move, which is unfavorable to their survival. Moreover, the lack of dissolved oxygen in the water body will also lead to their death due to lack of oxygen. Do not put the fish in the tank directly after preparing it, disinfect the tank first, then rinse it several times, and then put the fish in the water that has been raised.
Fish farming needs water, but not all kinds of water can be used. Of course, fish caught in the river can use river water or tap water, but you can't use the tap water you just received. You must dry the trapped water to ensure that the residual chlorine in the water has volatilized and the temperature is relatively suitable before you can use it for fish farming. Moreover, the water changed at ordinary times should be treated in the same way, so as not to affect the health of fish.
If it is already a fish tank, can not catch the fish directly into the tank, otherwise it may bring some harmful bacteria, so it needs to be disinfected first. Pour the yellow powder into the bag or other container containing the fish and take a medicinal bath for about 30 minutes, which can destroy most of the bacteria and prevent them from harming other healthy fish.
The fish caught in the river must first understand its feeding habits, according to different feeding habits to feed different food. Omnivorous fish like carp can choose a wide range of feed, but carnivorous fish like snakehead can only feed small fish, shrimp and other meat. Grass carp, on the other hand, need to feed plants.
