CATDOLL : CATDOLL: What precautions should be taken when raising rainbow trout in cages?

What precautions should be taken when raising rainbow trout in cages? Rainbow trout is now just starting a relatively popular breeding project. Rainbow trout itself has rich nutritional value, and their meat is a lot, but the bones are very soft and small and the smell is small. It is often used by many restaurants to eat fish. When its growth cycle is short, it shortens the time required from introducing fish to selling. Their high income has attracted many farmers to breed. But in the breeding process of rainbow trout, there are also many problems that need to be paid attention to. So, what should we pay attention to when breeding rainbow trout? Let's find out.

/n/nWhen breeding rainbow trout, we must choose feed reasonably. Rainbow trout are very sensitive to feed. They have very strict requirements on the size, shape and softness of feed. The size of feed particles not only affects the food intake of rainbow trout, but also affects their taste, which will have a great impact on the intestinal digestion of rainbow trout, so when feeding feed, we must pay attention to the particle size of fish at each growth stage and feed them what is suitable for them to eat.

/n/nIf the fish is particularly large and the feed is small, it will make it difficult for the rainbow trout to eat the feed. At the same time, it will sink to the bottom of the pond and cause pollution. If the fish is particularly small but there is a lot of feed, it will not make the fish feed and waste more delicious, and it will sink to the bottom of the pond later. So not only will we increase the amount of feed, but rainbow trout also have a high oxygen demand in the water. /n/nOxygen directly determines the growth and development of fish, and has a certain impact on eating and digestion. Too low oxygen will slow down the activity of fish, lose appetite, and make it difficult to digest food late, which will reduce their original growth rate and waste feed. If the normal growth rate of fish oxygen can be maintained, more feed will be used without waste, so we must pay attention to the oxygen in the pond.

If the oxygen content in the pond is low, we can add some oxygen supplement equipment, such as an aerator or feed chickens, so that we can provide a better living environment for the fish, and at the same time improve the quality of the fish, and also increase our income. Because rainbow trout is a creature suitable for living in cold water fish, their water temperature should not exceed 25 degrees. The optimal temperature for their growth is 15 to 18 degrees, but if the water temperature is below 10 degrees or above 25 degrees, the growth rate of rainbow trout will be seriously hindered. /n/n
