Artificial propagation and domestication methods of coilia ectenes

Abstract

The invention discloses artificial propagation and domestication methods of coilia ectenes, relating to a propagation and domestication method of fishes. The artificial propagation method comprises the steps of parent fishing, artificial insemination and incubation in a laboratory; and the domestication method comprises the steps of: 1. putting coilia ectenes fries of uniform size in a glass jar with water, wherein the main feeding bait is composed of 10 kinds of bait such as a compound feed, rotifers and the like, the average water temperature in the feeding period is 25 DEG C; the content of dissolved oxygen is higher than 6 mg / L, the content of ammonia nitrogen is lower than 0.14 mg / L, and the bait composite is fed four times every day; and 2. using the fish at the first stage as materials and continuing to feed the fish for 60 days, wherein the density of released is 50 fish per square meter, the same artificial feed is used in the period, and the feeding condition and temperatureare same. Therefore, mass propagation of coilia ectenes is ensured, the living rate is high, the weight of artificially domesticated coilia ectenes is increased, and the requirement of economical production is met.

Description

Technical field: [0001] The invention relates to a breeding and domestication technology of fish, in particular to an artificial breeding and domestication method of anchovy. Background technique: [0002] Plum anchovy, together with Taihu whitebait and white shrimp, are called "Taihu Three Treasures", and their production value is very high. However, under natural conditions, the growth and development of Plum anchovy are relatively slow, which is far from meeting the requirements of economical production. And from the point of view of the individual, the individual is lighter, and the survival rate of natural reproduction is also lower. In fact, the production of plum anchovy mainly relies on natural reproduction, which not only has a low reproduction rate, but also has a small output. In order to expand production and improve economic benefits, high-efficiency artificial reproduction is very important. However, in the current situation, although many scientific researche...

Problems solved by technology

[0002] Plum anchovy, together with Taihu whitebait and white shrimp, is called "Taihu Three Treasures", and its production value is very high. However, due to the slow growth and development of Plum anchovy under natural conditions, it is far from meeting the requirements of economical production.

And from the point of view of the individual, the individual is lighter, and the survival rate of natural reproduction is also lower.

In fact, the production of plum anchovy mainly relies on natural reproduction. Not only the reproduction rate is low, but also the output is small. In order to expand production and improve economic benefits, high-efficiency artificial reproduction is very critical.

However, in the current situation, although many scientific researchers have done a lot of research on the artificial reproduction technology of plum anchovy and made some major breakthroughs, in actual conditions, due to technology, environment and plum anchovy The reason for the complicated reproductive process of anchovy itself is that the artificial propagation technology is not perfect, and the large-scale artificial reproduction of anchovy is still being explored
