Problems solved by technology

Such measures have a certain effect on improving the effect of pearl cultivation, but if the sea area is stormy, it will cause frequent opening and closing of shells, resulting in a large number of "spitting cores", which seriously affects the effect of pearl cultivation; Aging breeding sea areas are more and more susceptible to pathogen infection, resulting in increased mortality of surgical shellfish
In recent years, in order to improve the survival rate and nuclear retention rate of planted shellfish, aquaculture enterprises have carried out experimental work on recuperation in industrial indoor cement ponds and outdoor large deep-water ponds. Although these two recuperation methods alone have good results, However, there are obvious deficiencies: the recuperation of industrial indoor cement ponds requires long-term feeding of a large number of single-celled algae, and the artificial cultivation of a large number of single-celled algae requires a large amount of cement pool resources and a large amount of labor cost input; the early stage of pond recuperation, Due to the lack of artificial anti-infection intervention in shellfish after nuclear implantation surgery, the mortality rate of shellfish is also relatively high

Embodiment 1

[0019] A method for postoperative recuperation of Pinctada martensii includes the following steps:

[0020] (1) Preparation of outdoor recuperation pond: 7 days before nucleation, the pond shall be filled with water to a depth of 1.5m or more, and 1g / m shall be applied 3 Concentration of urea and 0.5g / m 3 The concentration of phosphate fertilizer makes the transparency of the pond water body reach 1.2m~15m 10 days after fertilization;

[0021] (2) Preparation of indoor recuperation pool: 1 day before nucleation, fill the indoor cement pool with sand and filter seawater, according to every 4m 3 The standard for installing one air stone in the water body is to evenly arrange the air stone at the bottom of the pool, and adjust the air output of the air stone to 8L / min;

[0022] (3) Cage installation of nucleus scallops: According to the density of 40 scallops / cage, the nucleus implantation scallops are closely arranged on the bottom of the traditional conical culture cage with the left s...

Embodiment 2

[0027] A method for postoperative recuperation of Pinctada martensii includes the following steps:

[0028] (1) Preparation of outdoor recuperation pond: 10 days before nucleation, the pond should be flooded to a depth of 1.5m or more, and 2×g / m 3 Concentration of urea and 0.3g / m 3 Concentration of phosphate fertilizer can make the water transparency of pond water reach 1 m~1.2m 10 days after fertilization;

[0029] (2) Preparation of indoor recuperation pool: 2 days before nucleation, fill the indoor cement pool with sand and filter seawater, according to every 5m 3 The standard for installing one air stone in the water body is to evenly arrange the air stone at the bottom of the pool, and adjust the air output of the air stone to 10L / min;

[0030] (3) Cage installation of nucleus scallops: According to the density of 40 scallops / cage, the nucleus implantation scallops are closely arranged on the bottom of the traditional conical culture cage with the left shell facing up and the twi...

Embodiment 3

[0035] The survival rate and nucleus retention rate of the nucleus implant surgery shellfish recuperated by the present invention and the traditional method were compared, and the results are as follows:

[0036] Location: Zhanjiang Meizhen Pearl Co., Ltd. Pearl Culture Base, Dajing Village, Xilian Town, Xuwen County;

[0037] Time: April 8, 2017 to May 10, 2017.

[0038] On April 8, the outdoor recuperation pond was filled with water to a depth of 1.5m and applied 2g / m 3 Concentration of urea and 0.5g / m 3 Concentration of phosphate fertilizer; two days later, the density of the monocytic algae in the pond gradually increased, and gradually turned into a light yellow-green water color; the transparency reached 1.3m on April 15.

[0039] On April 13th, fill the indoor cement pool with filtered seawater at every 4~5m 3 The standard for installing one air stone in the water body is to evenly arrange the air stone at the bottom of the pool, and adjust the air output of the air stone to 8-1...

Abstract

The invention provides a postoperative recuperation method for pinctada martensii. The technical scheme is characterized in that pinctada martensii subjected to nucleus insertion firstly rest in an indoor cement pit for 7-10 d, antibacterial agents are applied for preventing pinctada martensii against infections and death so that survival rate of pinctada martensii subjected to nucleus insertion is increased; pinctada martensii are moved to an outdoor pond for rest so that the workload for manual cultivation of monodus subterraneus during indoor rest is greatly reduced; and meanwhile, the water for rest in the calm pond is good for decrease in opening-closing frequencies of shells so that the remained nucleus ratio is improved.

Description

Technical field [0001] The invention relates to a postoperative restoring method for Pinctada martensii, which belongs to the technical field of aquaculture. Background technique [0002] The postoperative recuperation of pearl oysters after nucleation is an important technical measure to improve the survival rate and nucleus retention rate of pearl oysters. The usual practice is to arrange the nucleus-planted Pinctada martensii in a traditional conical cage with the left shell facing up, increase the density of the pearl oyster to about 40 shells / cage, and place it in the sea for about one month. Check and remove dead shells frequently. Such measures have a certain effect on improving the pearl breeding effect, but if the sea area is strong, the shells will be opened and closed frequently, causing a large number of "nucleus spitting", which seriously affects the pearl breeding effect; and the wounds of the nucleus implantation surgery are increasingly polluted. The aging sea a...
