A method for monitoring the growth calcification rate of reef-building corals in natural sea areas

Abstract

The invention discloses a method for monitoring the calcification rate of reef-building coral growth in natural sea areas, which comprises the following steps: 1. A base is placed in the sea area where coral reefs are distributed, and a coral fixing base is installed on it; 2. The coral body is collected, and a weighing device is used Weigh its relative weight M0 in a predetermined liquid; stick it in the coral holding base to form a connecting body, air-dry, and weigh the relative weight M1 of the connecting body by the above weighing method; 3. Pass the coral holding base through the connecting piece Connect with the coral fixed base, and domesticate in situ for a period of time in the coral reef distribution sea area; 4. Separate the coral storage base from the coral reef distribution sea area, and weigh the relative weight of the connector Mi+1; 5. Put the coral storage base through the connection The piece is connected with the fixed base of the coral, and after the culture time ti in the coral reef distribution sea area, repeat step 4, record the relative weight Mi+2 of the connection body after the elapsed time ti; 6, pass (Mi+2-Mi+1) / (Mi+ 1-M1+M0) / ti to get the calcification growth rate of the coral body per unit weight in ti time period.

Description

technical field [0001] The invention belongs to the research field of coral reef physiology and ecology, and relates to a method for monitoring the growth calcification rate of reef-building corals in natural sea areas. Background technique [0002] Accurately measuring the growth rate or calcification rate of reef-building corals in natural sea areas can analyze the pressure of environmental stress, the correlation with certain environmental factors and the intensity of their influence. If the dominant species of a coral reef ecosystem is used as the experimental object, it can reflect the overall growth status of the system. Therefore, this method is an important means of coral reef ecosystem research. It can be used to quantitatively explore the seasonal and interannual changes in the growth rate or calcification rate of reef-building corals. It can accurately measure the growth and stress conditions of corals and even coral reef ecosystems in a certain period of time, a...

Problems solved by technology

However, in previous on-site cultivation experiments, there are usually two methods. First, the experimental coral body is fixed on a large substrate, which cannot be moved and weighed, so it is not suitable for this method; The object sticks to a small piece of PVC board, but it is difficult to prevent the attachment of other organisms, which causes a large error in the weighing accuracy
