Problems solved by technology

Simulating natural ecology under artificial conditions When cultivating on a sandy substrate, residual bait and digestive residues are not easy to remove, and long-term cultivation will cause substrate deterioration and death. Separation from the sediment that makes up the substrate, the collection of fertilized eggs has become the technical bottleneck of artificial reproduction

Embodiment

[0033] In April 2011, the Jiangsu Provincial Oceanic and Fisheries Research Institute collected 320 wild adult anemones from the natural sea area as broodstock, and placed them in 2 broodstock culture tanks for cultivation, adding filtered seawater with a salinity of 20-26‰, PH7.8-8.6. When the water temperature rises above 14°C, feed daily, remove residual bait and debris in the separation tank of digestion residue every day, and clean the separation tank. After 3 months of cultivation, when the water temperature rises above 24°C-26°C after June, the broodstock gradually matures and begins to lay eggs and ovulate. The fertilized eggs in the egg-collecting cages are collected every day for hatching and raising 14 million seedlings. More than 90% of them are hatched and cultivated into floating larvae.

Abstract

The invention relates to a cultivating method of sea anemone parents, comprising the following steps: collecting sea anemones which are healthy, vigorous, and unharmed, and have complete tentacles and intact foots; placing the anemones in a parent cultivating system to make the anemones spawn and produce milt; collecting fertilized eggs after the gametes being fertilized; and transferring the fertilized eggs to a nursery pond to perform embryo cultivation and breed. According to the invention, the cultivating method of sea anemone parents has advantages that the feeding is convenient to manage, the cultivating method is convenient for long-term cultivation and is easy to observe, the cultivating effect is good, the water is recycled, the fertilized eggs are collected continuously and the like, the technical difficulty that the sinkable fertilized eggs from anemones in a life form collected by digging are hard to collect efficiently is solved, the hatching rate of the fertilized eggs is high, the residual feeds and the undigested residuals are easy to clear away, and the cultivating method has strong operability and good practicability.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a sea anemone broodstock cultivation method. Background technique [0002] Chinese fairy shadow sea anemone is large in size, with high nutritional value and delicious taste. It is a high-end edible aquatic product. The toxin of sea anemone can be used to lower blood pressure and blood coagulation. It has analgesic effect on heart nerves and muscles. Medicinal value of aging and anti-cancer, Chinese fairy shadow sea anemone is also the object of biotoxin research and ornamental aquarium. It is naturally distributed in the coastal areas of my country, but the natural resources are few. At present, the commodity of Chinese fairy shadow sea anemone completely depends on the harvesting of natural resources, which cannot meet the market demand. It is an inevitable way for the development of aquaculture to carry out research on artificial breeding and breeding technology. [0003...
