Problems solved by technology

To determine the trace elements on the shells, the samples need to be processed first, but there is currently no fast and accurate method to process and measure the trace elements on the shells, which is not convenient for later analysis of its living environment and life history

Embodiment 1

[0045] A pretreatment method for assessing clam release effect by using trace elements, comprising the following steps:

[0046] (1) Randomly select 20 clams raised in the laboratory and 20 clams caught in the wild, respectively, and number the clams raised in the laboratory and clams caught in the wild;

[0047] (2) Boil clean water, put in the clams, and boil for 4-6 minutes, so as to separate the muscles from the shells;

[0048] (3) Take out the clam, and then use a scalpel and tweezers to remove the muscles and connective tissue inside the shell. Some connective tissues are difficult to separate and need to be removed with a scalpel and tweezers. These tissues will affect the analysis results, and the clam shell should be cut , respectively cut the top of the shell of the clam seedling and the edge of the shell of the adult clam, put it into a ziplock bag, number, spare, soak the scalpel and tweezers in the acid tank overnight, clean with ultrasound for 9-11 minutes, rins...

Abstract

The invention discloses a pretreatment method for evaluating a clam release effect by using microelements and belongs to the field of aquatic products science. The pretreatment method for evaluating the clam release effect by using the microelements comprises the steps of selecting clams raised in a laboratory and wild clams at random and numbering the clams raised in a laboratory and the wild clams separately; and boiling clear water, putting the clams into the clear water and boiling for 4-6min. Microelements such as Sr on shell samples can be completely decomposed, the pretreatment speed can be improved, a novel pretreatment method is provided for evaluation of the clam release effect, the microelements on shells can be quickly and accurately treated and measured, and later analysis of the content of the microelements of the clams at different growth stages is facilitated, thereby further analyzing the living environment and the life history of the clams.

Description

technical field [0001] The invention relates to the field of fisheries, in particular to a pretreatment method for assessing clam release effect by using trace elements. Background technique [0002] Meretrix meretrix, also known as flower clam, is one of the important economic species in my country's coastal waters, mainly distributed in my country's mainland and the coast of Taiwan. Meretrix meretrix is ​​delicious and nutritious, and has high therapeutic and medicinal value. In recent years, due to overfishing, environmental pollution and other factors, wild clams have gradually declined. In order to better protect the clams, the release of clam seedlings has been widely carried out in my country's coastal waters. After the release, the effect of the release needs to be evaluated. [0003] The traditional method of evaluating the release effect of recapture by marking is not suitable for the evaluation of the release effect of clams due to the low recapture rate, high ma...
