Artificial propagation technology for Rhodeus sinensis

Abstract

The invention relates to the field of Rhodeus sinensis propagation, in particular to an artificial propagation technology. The invention mainly relates to an artificial propagation technology for Rhodeus sinensis. The artificial propagation technology for the Rhodeus sinensis comprises infrastructure equipment, parent fish selection, parent fish temporary rearing, parent fish maturing acceleration, parent fish spawning, ovum pickup and incubation, wherein the parent fish maturing acceleration, the parent fish spawning, the ovum pickup and the incubation are the core of the artificial propagation technology for the Rhodeus sinensis. According to the artificial propagation technology for the Rhodeus sinensis provided by the invention, a square pond of 1 mu or a cement pit of 10-50m<2> is selected, and is equipped with micropores to enhance oxygen. Parent fishes are characterized in that lateral lines are incomplete, and the back upper place of each spiracle of each parent fish has shoulder patches. Male fishes are red in eye socket, and bright in body color; the abdomen of each female fish has a strip ovipositor. 4.5g / l of VC is added to temporary rearing water; before put, the parent fishes are soaked in 5mmg / l of potassium permanganate for 10 minutes; the density of the potassium permanganate is lower than 0.5kg / m<3>, and a toad of 50g is cultivated in every 4m<2> of water to prevent fungal diseases. 10g / kg of minced earthworm meat and spirulina powder is fed. The female-male ratio of the parent fishes is 1:1, oxytocic is injected after the parent fishes are narcotized by 30mg / lMS-222, the ovum pickup is performed by using Sinanodonta woodiana or unio douglasiae which is 8-10cm wide, and the ratio of the Sinanodonta woodiana or the unio douglasiae to the fishes is 2:3. The Sinanodonta woodiana or the unio douglasiae is harvested once every two days, the ovum-contained Sinanodonta woodiana or the ovum-contained unio douglasiae is moved to a hatching pond, and corresponding ovum-free Sinanodonta woodiana or corresponding ovum-free unio douglasiae is supplemented.

Description

technical field [0001] The reproduction technology of the Chinese squid fish developed by the present invention relates to the artificial reproduction technology field of the small fish of the squid category, especially the artificial reproduction technology of the squid squid. force. Background technique [0002] The squid belongs to the subfamily Acheilognathinae (Cyprinidae) of Cypriniformes (Cypriniformes). Other freshwater basins other than the Heilongjiang water system in China. The squid is a natural wild fish with rich natural resources. Its meat is delicious and easy to catch. It is a large number of fish catches, and it is some small fish that people like to eat. There used to be a local saying in Jiangsu that "eat squid in winter and eat squid in summer". Using squid and other indigenous wild fish as raw materials, Jiangsu's famous Qinhu eight fresh products were developed. As high-end consumer products, they are deeply loved by consumers. [0003] There are ma...

Problems solved by technology

At the same time, the spawning time of the fish species is inconsistent, and the systematic operation of the fry is difficult; the oyster fish needs to spawn in the gill cavity of the mussel to reproduce successfully, which is affected by factors such as different mussel species, mussel body size, and mussel health status. The success rate of eggs is low, and the large-scale reproduction of fry is difficult, which has become a bottleneck problem restricting the protection, development and utilization of the resources of the Chinese squid.
