What is the yield of artificial reproduction of baby fish?
Recently, everyone has been discussing how much the baby fish can reproduce. Personally, the reproduction yield of the baby fish is far from its theoretical output. The baby fish began to mature in five years and can lay eggs weighing 1.5 kg to 15 kg.
In actual production, most doll fish weigh between 3 kg and 15 kg, and the number of eggs laid ranges from 300 to 2000, but the fertilization rate varies widely, with 90%. There are also those who are not fertilized at all, after technological improvement. The fertilization rate is increased to 90%, the spawning rate is 90%, and the hatching rate is from 90% to 10%.
Suppose the technology of baby fish is improved to 90% of the spawning rate, 90% of the fertilization rate, 90% of the hatching rate. It is calculated on the basis of an average of 1000 eggs per baby fish. The average emergence rate is more than 600, that is to say, each female produces an average of 600 fry. In fact, in production, now is really low, the average breeding base is now an average of 1:30 within the majority, most rely on the number to win, a lot of waste of fish. Even lose confidence in artificial reproduction, switch to ecological reproduction, ecological reproduction encountered difficulties. With the breakthrough of artificial reproduction technology, the disadvantages of ecological reproduction are revealed.
Personally, I think that artificial reproduction has a bright future, and the key lies in technological breakthroughs. Now many farms, lack of technical personnel, do not have their own unique technology, follow others, the ecology is good to follow the trend to do the ecology, manual good to follow the trend to do artificial, do not understand measures to local conditions, failure is inevitable.
Baby fish reproduction, artificial reproduction is a major trend, technological breakthrough is a matter of time, ecological reproduction as an auxiliary. Artificial breeding of fish fry will make a big breakthrough in a few years.
