Matters needing attention in breeding rainbow trout

Rainbow trout is a relatively hot breeding project emerging now, rainbow trout has rich nutritional value, and the meat is spiny and soft, fishy, so it is a high-grade edible fish in many restaurants. Its growth cycle is short and the cost is not high, so it is very popular in the market. Higher economic interests have attracted a large number of friends to breed. But there are many places that need to be paid attention to in the process of breeding, so what should be paid attention to? Let's take a look at it.

1. Feed

Rainbow trout is very sensitive to feed, and the shape and specification of feed is very important for fish to reject food. The size of the feed will not only affect the taste of rainbow trout, but also have a certain impact on the digestion of rainbow trout, so when feeding pellet feed, we must pay attention to the fish size of each stage and feed the appropriate feed. If the fish is large and the feed is too small, it will make it difficult for the fish to eat and cause the feed to sink into the drop. If the fish is small and the feed is large, it will not be conducive to the eating of the fish and make the feed melt in the water, reducing the utilization rate of feeding.

2. Dissolved oxygen content

The content of dissolved oxygen in water not only has a great impact on the growth and development of fish, but also has a certain response to the eating and digestion of fish. If the dissolved oxygen content is too low, it will make the appetite of the fish worse, and it will be difficult to digest after eating, reducing the original growth rate and wasting feed. If the amount of dissolved oxygen is appropriate, the fish can grow normally, maintain a good growth rate, and the utilization rate of feed will also be increased. Therefore, maintaining a good dissolved oxygen content in the pond can not only make fish grow better, but also improve the quality of fish meat and increase the commercial value.

3. Water temperature

Rainbow trout is a cold water fish, its suitable water temperature must not exceed 25 degrees, the most suitable water temperature for rainbow trout growth is 16-18 degrees, if it is lower than 8 degrees or higher than 20 degrees, then the growth rate of rainbow trout will be significantly reduced. Above 25 degrees will stop eating and die within a week. In the case of high temperature in summer, ice water should not be used to cool down. well water should be drawn to change the temperature, and proper heat preservation should be taken in winter. Keeping the pool water between 16 and 18 degrees can accelerate the growth of rainbow trout and the utilization rate of feed.

4. Feeding amount

Rainbow trout should not be fed too much or too little in a day. Too little rainbow trout will not have enough to eat, but also in a state of hunger, reduce the growth rate of rainbow trout, too much feeding, not only waste feed, but also make the residual feed dissolved in water, affecting the water quality. It is easy to produce diseases, and the appropriate feeding amount is not only beneficial to the feed utilization rate of rainbow trout, but also promote the growth and development of rainbow trout. The protein content in the feed should occupy the first place, and the fish at different growth stages should be selected and fed separately to promote the good growth of each fish.

These are the aspects that need to be paid attention to in the process of breeding rainbow trout. Although rainbow trout is a new culture project, its breeding prospect is still very good. The market price is also very considerable, which is the most important aspect that attracts the interest of many people. So I hope you can breed correctly, walk in the vanguard of this industry, and also hope that this article of the editor can help you.
