A kind of method and application of measuring calcium carbonate deposition rate of cultured shellfish

Abstract

The invention belongs to the technical field of seawater shellfish cultivation, and discloses a method and application for measuring the calcium carbonate deposition rate of cultured shellfish, including on-site weighing of the shellfish to be tested, short-term running water temporary cultivation, measurement of the flow rate and post-cultivation method. On-site sampling and storage of seawater, indoor measurement of total alkalinity of seawater samples, and calculation of calcium carbonate deposition rate of cultured shellfish to be tested based on the measured shellfish weight and water velocity. The present invention is based on the precise component method of analytical chemistry, reflecting the growth status of shellfish, the whole operation can be completed within 1 day, and the intervention on the growth of shellfish can be minimized in the on-site measurement in the breeding area, without affecting the next stage of the measured individual The growth of shellfish is suitable for monitoring the real-time growth status of shellfish. Compared with the prior art, the present invention provides direct and real-time data reference for farmers to grasp the growth conditions of cultured shellfish in real time, and provides strong support for farmers to formulate and improve breeding programs more flexibly.

Description

technical field [0001] The invention belongs to the technical field of seawater shellfish culture, and in particular relates to a method and application for measuring the calcium carbonate deposition rate of cultured shellfish. Background technique [0002] At present, the traditional method of monitoring the growth of shellfish is to measure the length and width of the shell with a ruler, and weigh the fresh weight with a balance. Since shell growth and weight gain take a long time, it is necessary to wait 20-30 days to grasp the growth status of shellfish. This traditional method is not only time-consuming, but also separates the growing and entangled shellfish individuals during the measurement process, which is time-consuming and labor-intensive and will cause damage to the shellfish, thereby affecting the growth of the measured individual. Calcium carbonate deposition rate is a direct, reliable and accurate indicator of shellfish growth. Although this indicator can be ...

AI Technical Summary

Problems solved by technology

This traditional method is not only time-consuming, but also separates the growing and entangled individual shellfish during the measurement process, which is time-consuming and labor-intensive, and will cause damage to the shell, thereby affecting the growth of the measured individual

Calcium carbonate deposition rate is a direct, reliable and accurate indicator of shellfish shell growth. Although this indicator can be measured indoors in a controlled environment, the outdoor environment is complex and there is no mature method that can be applied to on-site measurement.

[0003] Through the above analysis, the problems and defects of the existing technology are: the traditional method of monitoring the growth of shellfish is time-consuming, time-consuming and labor-intensive, and will cause damage to the shell, affecting the growth of the measured individual
