Embodiment Construction

[0008] A method for raising seedlings of Pleurotus chinensis, comprising the following steps:

[0009] Select 2- to 4-year-old P. chinensis with a shell length of more than 20 cm as broodstock, remove the attached organisms on the shell surface of the broodstock, and put them into floating cages for ripening cultivation after washing. The water temperature is 26°C. The bait is flat algae and Chrysoflagellates, and the daily feeding amount is 200,000 cells; the water is changed 5 times a day, and the amount of water changed each time is 1 / 3 of the total water amount; after 30 to 45 days of ripening cultivation, broiler shellfish Gradually mature.

[0010] After drying the broilers in the shade for 3 hours, put them in a 100-liter plastic bucket, which is seawater, and put 6 to 8 shellfish in each bucket, and irradiate them with a 30W ultraviolet lamp for 3 hours, so that the mature broodstock will discharge sperm and eggs, and then inflate them with water. Or under agitation c...

Abstract

The invention provides a seedlings-cultivating method of the atrina pectinata, which comprises the steps of: selecting the atrina pectinata as a parent scallop, so that the parent scallop is gradually matured by means of fertilizing and cultivating; drying the parent scallop in the shade, and irradiating the dried parent scallop by a 30W ultraviolet lamp for 3 hours, so that the matured scallop discharges the sperm and the ovum, and the sperm and the ovum are voluntarily fertilized in the water; after the fertilization, cultivating to form into the D-shaped veliger larva after 25 hours; when the larva is cultivated to be the D-shaped veliger larva, collecting the D-shaped veliger larva into a seedlings-cultivating pond to cultivate by a 300 screen mesh dragnet; when the larva cultivates the feet, acquiring the seedlings by putting a seedlings acquiring bag; and overturning the seedlings acquiring bag after the juvenile scallop is washed, and splashing the juvenile scallop into another pond paved with the sand, wherein the bait organism is the tetraselmis and the pyramimonas sp after the juvenile scallop is attached.

Description

technical field [0001] The invention relates to a method for raising seedlings of P. chinensis. Background technique [0002] As a large-scale marine shellfish with high economic value, it can not only be consumed in the domestic market, but also exported to earn foreign exchange. The current production volume of C. chinensis is far from meeting the market demand. The reason is that the cost of the existing breeding methods is high, Efficiency is low, to a certain extent, has limited the development of the breeding industry of Kushijiang. Therefore, to explore a low-cost, high-yield, and easy-to-promote method for culturing C. chinensis seedlings has become an urgent problem to be solved in the C. persicae breeding industry. Contents of the invention [0003] The purpose of this invention is to provide a kind of method for raising seedlings of Pleurotus chinensis, comprising the following steps: [0004] Select 2- to 4-year-old P. chinensis with a shell length of more th...
