Embodiment Construction

[0035] The content of the present invention will be further described below through specific examples.

[0036] In May 2014, in the Hezhou North Base of the Hekou Fisheries Research Institute in Doumen District, Zhuhai City, artificial breeding and intensive breeding of grass insects were carried out using cement nursery ponds and culture soil ponds. The method for artificial breeding and intensive cultivation of the grass worm comprises the following steps:

[0037] 1), choose parent

[0038] Collected 5Kg grass worms from the natural place of origin of grass worms, according to the whitening of the abdomen and warty feet of the grass worms, the characteristics of producing wide and flat pulp-like setae are selected to select the sexually mature Henieris worm body; The papillae and verrucous setae are all slurry-like setae, the tail is dark red, and there is a longitudinal milky white band in the middle. Observed under a magnifying glass, there are chrysanthemum-like papilla...

Abstract

The invention provides an artificial breeding and intensive cultivation method for tylorrhynchus heterochaetus. The artificial breeding and intensive cultivation method includes the steps of parent selecting, artificial fertilization, artificial incubation, nursery pond preparing, artificial breeding and intensive cultivation. The technical problems of the tylorrhynchus-heterochaetus breeding male-female proportion, breeding water environment conditions, young tylorrhynchus heterochaetus food intake, tylorrhynchus-heterochaetus pond cultivation and the like are solved, and therefore artificial breeding and intensive cultivation of tylorrhynchus heterochaetus are achieved; seed resources can be provided for large-scale cultivation of tylorrhynchus heterochaetus, the cultivation yield of tylorrhynchus heterochaetus can be increased, and the artificial breeding and intensive cultivation method is of great significance in protecting natural tylorrhynchus heterochaetus resources and meeting the consumption requirement of the market for tylorrhynchus heterochaetus.

Description

【Technical field】 [0001] The invention relates to a method for artificial breeding and cultivation of special aquatic products, in particular to a method for artificial breeding and intensive cultivation of grass insects. 【Background technique】 [0002] Grass worm, scientific name Tylorrhynchus heterochaetus, belongs to Invertebrate Annelids, Polychaetes, Migratory Order, Nereistae, and Tylorrhynchus heterochaetus in systematic classification. Grass worms belong to estuary species, and different from traditional clamworm species in seawater areas, the larvae of grass worms can grow in fresh water. Because the grass insect lives in the paddy field for a period of time in its life cycle, people mistakenly believe that the grass insect feeds on the grass seedlings, so it is called the grass insect. Wo Chong is also known as the "Cordyceps sinensis" in the water. It has always been regarded as a delicacy in the Pearl River Delta. It has the medicinal effects of nourishing the s...
