A method for artificially inducing labor and hatching of clam worm

Abstract

The invention discloses a method for artificially oxytocinizing and hatching clamworm, which comprises the following steps: S1, pretreatment of facilities and equipment: cleaning all facilities and equipment with clean water, and then thoroughly disinfecting them; ; S2, seawater and freshwater pretreatment: sterilize and filter the used seawater and freshwater; S3, parent selection; S4, artificial induced labor and fertilization: put the selected clam worm parents in the induced labor hatching bucket for free mating , laying eggs, fertilization; S5, artificial hatching of fertilized eggs: artificially hatch fertilized eggs in the hatching bucket for induced production; S6, cultivating fertilized eggs: fertilized eggs develop to 3 ganglion larvae, emerge from membranes, and collect with 300-mesh sieve silk net Afterwards, the pools were cultivated. The artificial oxytocin and hatching method of C. verruca in the present invention controls the most suitable environmental conditions for artificial oxytocin, optimizes the environment for laying eggs, fertilization and hatching, improves the fertilization rate, survival rate, and hatching rate, and significantly reduces labor intensity and production. cost.

Description

technical field [0001] The invention relates to the technical field of artificial reproduction of Nereus verrucas, in particular to a method for artificially inducing labor and hatching of Nereus verrucas. Background technique [0002] Tylorrhynchus heterochaetus, also known as Nereus heterochaetus, belongs to the phylum Annelida, Polychaeta, Nereidae, and Tylorrhynchus. Because it likes to live in the paddy fields, and the production season is concentrated in the season when the seedlings are heading and blooming, it is commonly known as "grass worms". It is an omnivorous animal that feeds on unicellular algae and animal and plant carcasses, and can effectively utilize the silt in the sediment. nutrient content. It is delicious, nutritious, and good in medicine and food. It is regarded as a famous water treasure in Guangdong, Guangxi, Fujian, Hong Kong, Macao and Southeast Asia, and has been highly sought after by diners for a long time. According to the "Supplement to C...

Problems solved by technology

[0006] Aiming at the above-mentioned problems, the present invention aims to provide a method for artificially induced labor and hatching of Verrucous nereis, which overcomes the defects of backward technology, low efficiency and poor stability in the existing methods of artificially induced labor, fertilization and hatching of fertilized eggs, and provides a A simple, efficient and reliable method for artificial oxytocin, fertilization and hatching of fertilized eggs of C. verrucosus, by controlling the most suitable environmental conditions for artificial oxytocin, optimizing the environment of oviposition, fertilization and incubation, and improving the fertilization rate, survival rate, and hatching rate, significantly reducing labor intensity and production costs
