Embodiment Construction

[0057] Further description will be given below in conjunction with specific examples. This embodiment is carried out in Shandong Rizhao sea area.

[0058] 1) Sea area selection:

[0059] Step 1-1, in the south of the estuary of Liangcheng in Rizhao, north of the estuary of Xiuzhen River, the sea area where wild golden squid grows, survey along the coastline, select the shoreline where there are no rivers entering the sea, no large farms, factories and domestic waste water outlets. Areas free of pollutants (including industrial pollutants and domestic garbage) are primary sea areas;

[0060] Step 1-2, measure the water temperature and salinity of the primary sea area from May to August, and set the water temperature at 15°C to 30°C, the salinity at 26 to 33, and the water depth above 3m as the secondary sea area, for example, the water depth is 3m , 5m, 7m, 10m, 13m, 17m, 23m, 28m, 35m, 42m, 47m, 56m;

[0061] Step 1-3: Take the seawater samples from the double-selected sea ...

Abstract

The invention relates to the technical field of culture and proliferation of aquatic products, in particular to a sepia esculenta fry proliferation method. The method is characterized by comprising following steps: 1), selection of sea regions: a sea area with seawater meeting the first-class seawater standard is selected as a fry proliferation region, and a sea area meeting the second-class seawater standard is selected as an alternative proliferation region; 2), fry breeding: sepia esculenta which is obtained by sea fishing or bred artificially is taken as a parent, when fertilized eggs areproduced by the parent, egg attached bases are transferred out and put in a hatching pond, and the hatching pond is continuously taken as a juvenile sepia esculenta culture pond after juvenile sepia esculenta is hatched out; 3), discharging of fries out of the pond: a fry discharge box is customized and put in a foam box, and the sepia esculenta fries are sucked into the fry discharge box; 4), proliferation on the sea: fry bags are loaded on a ship and thrown dispersedly; 5), recapturing on the sea: the immature sepia esculenta is fished as a commodity for processing and sale, and sexually mature male or female individuals are fished and serve as parents for fry culture. The method has the advantage of integrating protection and utilization.

Description

technical field [0001] The invention relates to the technical field of aquaculture multiplication, in particular to a method for multiplication of golden squid seedlings. Background technique [0002] As one of the important economic cephalopods in my country's coastal areas, golden squid is an excellent wild species with high economic value. However, in the late 1980s, with the increase of fishing intensity and the influence of marine environment, The resources of golden squid have declined significantly, and the number of wild populations of golden squid has been declining. In order to protect and maintain this characteristic marine fishery resource, it is imperative to proliferate and release golden squid and restore resources. In recent years, research on golden squid broodstock temporary breeding and artificial seedling technology research has been carried out, and sea-caught and artificially bred golden squid are used as broodstock to cultivate artificial seed. has bee...
