1. Selection of feed grades
It is recommended that fish farmers should use the break-even point of breeding as the main basis. When the price of single-pound fish does not exceed the cost of single-fish farming feed, low-grade feed should be selected. When the price of single-pound fish is higher than the cost of single-pound feed, it should be selected. High-grade feed, and the higher the grade, the more cost-effective.
2. Selection of feed particle size
The size of the feed particle size is generally selected from the range of 1/4 to 2/3 of the longitudinal length of the fish mouth crack, and then selected according to the inherent crack size of the fish. For example, grass carp with larger cracks can choose a slightly larger proportion of longitudinal mouth cracks 1/2 to 2/3; white fish, squid, squid, etc. choose a slightly smaller ratio of 1/4 to 1/3. The aspect ratio of the feed is also determined according to the specific variety, generally between 1.5 and 2.5:1. Therefore, before purchasing aquatic feed, it is necessary to first determine the size of the fish, and determine the appropriate feed size according to the size of the fish. In this way, neither feed is wasted nor the fish is ingested.
3. Selection of feeding method
(1) The importance of taming. Fish generally require domestication to the surface of the water to concentrate on feeding, and then start normal feeding. The method of taming can be flexible and varied, most of the time is 3 to 10 days, and the longest is no more than half a month, that is, it can be tamed successfully. Many people are too cumbersome or even unwilling to tamer, or lack patience and taming is unsuccessful. I don’t know how the fish grow, the output budget, and so on. The advantages of domesticated fish body feeding can be directly observed: the growth of the fish body, the size of the fish, the choice of the feed variety, the particle size and the reasonable amount of feeding; the flexible control of the growth rate of the fish according to the market conditions and the benefit budget, Timely listing to get a good return on profits and so on. It can be seen that the importance of taming is self-evident.
(2) Pay attention to the feeding method. There are many ways to feed, such as feeding speed, feeding area, feeding times, and placement of automatic feeding machine. The feeding method should be flexibly adjusted according to the specific situation. For example, in the polyculture mode of grass carp, carp and carp, grass carp fast food and large amount of food, squid and squid eat "Sven", if you do not pay attention to the improvement of feeding method (feeding speed, shortening feeding time, etc.) ), squid and squid will not grow long. Fish farmers should always think about the feeding method and breeding effect, so as to take timely measures to adjust the improper feeding method to improve the breeding efficiency.
