Embodiment Construction

[0014] Specific embodiments of the present invention will be described below.

[0015] A method for measuring the cultivation density of aquatic animal plankton larvae is carried out according to the following steps:

[0016] First aerate the nursery container for at least 30 minutes, and then use a stirring tool to stir the water in the nursery container. The purpose of the above two steps is to make the planktonic larvae randomly distributed in the water body, and use a quantitative beaker to remove from the nursery container under stirring. Obtain a certain amount of water and record the volume V of the obtained water;

[0017] Then use a 500-mesh sieve to filter out the seawater in the quantitative beaker, use a straw to suck out all the larvae on the sieve, pour all the larvae into a 10ml burette, and use a needle to fill the 10ml burette with filtered seawater until the total amount of seawater and larvae When the volume reaches 10ml, use a 500-mesh sieve to filter out the sea...

Abstract

The invention discloses a cultivation density measuring method for aquatic animal planktonic larvae. The cultivation density measuring method for the aquatic animal planktonic larvae is scientific, rigorous and standard. The cultivation density measuring method for the aquatic animal planktonic larvae comprises firstly measuring and computing various middle parameters and finally obtaining the planktonic larva density by computing. Compared with the traditional method, the cultivation density measuring method for the aquatic animal planktonic larvae has the advantages of being scientific and effective, high in reliability and standard in operation, not depending on experience of operators, providing real and reliable data and bases for cultivation and research of planktonic animals, particularly being applicable to popularization and application in the aquatic field and being significant in scientific meaning and wide in market prospect.

Description

Technical field [0001] The invention relates to a method for measuring density, in particular to a method for measuring the cultivation density of aquatic animal plankton. Background technique [0002] Factors such as the growth rate of aquatic animal larvae, survival rate, and the amount of feed in planktonic larvae are all closely related to the larval breeding density: a larger breeding density requires a large amount of feed to be fed, which will lead to higher breeding costs and at the same time Causes larval growth retardation, deformity, and the survival rate will also decrease. If the density is too small, it will waste bait resources and labor. Therefore, it is particularly important to accurately quantify and adjust to a suitable breeding density in aquatic animal breeding and breeding experiments. However, the larvae of aquatic animals are generally small (mostly less than 1 mm), and it is difficult to directly and accurately quantify the density of larvae with the n...
