Embodiment 1

[0028] (1) The resuscitation container is a plastic water tank made of HDPE material with a volume of 96L. Add 50L of water from the breeding system to the temporary water tank. The salinity is about 33‰. Use a thermometer to measure the temperature of the temporary water. When the water temperature is higher than that of the aquaculture system, put the ice bag in the water body in time to cool down; use the air pump to continuously inflate the recovery water body for 24 hours;

[0029] (2) preparing a volume fraction of 1% ethanol solution, 50% soy sauce and 0.5mol / L taurine solution with double distilled water;

[0030] (3) Take 18 oysters with similar specifications from the cultured water body and clean them with sea water; open a small hole in the shell of the oyster to let the liquid contained in the shell flow out; be careful not to hurt the soft tissue of the oyster.

[0031] (4) Mix the prepared taurine solution, ethanol solution, and soy sauce 1:1:1 (V:V:V) to make a...

Embodiment 2

[0035] Mix ethanol solution, taurine solution and soy sauce in step (4) in Example 1 according to 2:2:1 (V:V:V) to prepare mother liquor. Other conditions are with embodiment 1.

Embodiment 3

[0037] Mix ethanol solution, taurine solution and soy sauce in step (4) in Example 1 according to 2:1:1 (V:V:V) to prepare mother liquor. Other conditions are with embodiment 1.

[0038] The comparative test results of Examples 1-3 are shown in Table 1.

[0039] Table 1 Test comparison results

[0040]

[0041]

[0042] It can be concluded from Table 1 that ethanol solution, taurine solution, and soy sauce were mixed in different proportions, and then diluted to different concentrations for experiments. As the volume fraction of the mixed solution increased, the time required for oysters to open their shells shortened, but the survival rate of oysters continued to decrease. The above experimental data show that when taurine solution, ethanol solution, and soy sauce are mixed 1:1:1 (V:V:V), and then the concentration is diluted to 1-5%, the time required for oyster shell opening is short, and the survival rate High, causing little harm to oysters.

Abstract

The invention discloses a solution and a method for quickly opening oyster shells. The solution consists of a soy sauce solution with a volume fraction of 50%, an ethanol solution with a volume fraction of 1%, and a taurine solution with a concentration of 0.5mol / L. It is made by mixing the volume ratio of 1:1:1. After diluting the mixed solution to a volume fraction of 1-5%, a small hole is opened on the oyster shell with an awl, and the diluted oyster is injected into the shell through the small hole. 1ml of the mother liquor makes oysters open their shells quickly in a short time, which is simple and easy, low in cost and remarkable in effect. The method of the invention does not need to kill oysters, is convenient for continuous operation, reduces damage to oysters at the same time, and facilitates operations such as tissue living sampling, egg collection, semen collection, and blood collection on oysters in later experiments.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a solution and a method for rapidly opening oyster shells. Background technique [0002] Oysters generally live in the intertidal zone of the sea, and their lifestyle is fixed filter feeding, which is less affected by changes in temperature and salinity. It is a representative bivalve mollusk with high nutritional value, short life cycle, and environmental protection Strong tolerance and other characteristics. Oyster is currently the largest and most productive marine economic shellfish in the world. Oyster has become a "model organism" for the study of marine shellfish. Due to its special physiological structure, it is extremely difficult to actively open the shell, which greatly hinders the development of oyster research. [0003] When carrying out experimental observation and operation on oysters, such as live sampling, ovum collection, semen collection, blood collection...
