Method and device for measuring biomass of cultured sponge

Abstract

The invention discloses a method and a device for measuring the biomass of cultured sponge, which relate to sponge animals. The measuring device is provided with a base, a container, a piston, two conduits, a handle and a measuring cylinder, wherein the lower end port of the container is adhered with the base; the container is fit with the piston; the container is provided with a baffle ring; the topmost end of the arc in the middle of the piston has a small hole; the small hole is connected with the second conduit through the first conduit; the handle is arranged on the surface of the piston; and the second conduit is connected with the measuring cylinder. The measuring device is arranged on the surface of a substance; the piston is opened, seawater providing a sponge growing environment is filled into the container; the piston is mounted, the second conduit is disconnected from the measuring cylinder, the piston is pressed to the position of the baffle ring, and all gas and excessive seawater in the container are discarded from the small hole in the middle of the piston; the piston is opened, the second conduit is connected with the measuring cylinder; and the sponge to be measured is filled into the container, the piston is mounted, the piston is pressed to the position of the baffle ring again, and the biomass of the cultured sponge is obtained by subtracting the known volume of attached materials from the total volume of the sponge and the attached materials.

Description

technical field [0001] The invention relates to a sponge, in particular to a method for measuring the biomass of a cultured sponge and a device thereof. Background technique [0002] Sponge is the simplest multicellular animal in the ocean, and it is the abbreviation of all animals in the phylum Porifera. It has no differentiation of tissues and organs, and no fixed morphological structure. Different from ordinary metazoans, sponges live sessilely, and the external shape of sponges will change with the shape of the surface of the sessile and the change of living environment. Therefore, it is very difficult to accurately measure the "body length" and body weight / biomass of the sponge, which is also the bottleneck restricting the evaluation of the growth rate of the sponge. [0003] Studies have shown that there are a variety of microorganisms symbiotic in the sponge, and their secondary metabolites provide humans with a large number of available new compounds. The sponge ha...

Problems solved by technology

This method is very unsuitable for on-site experiments, and the operation is cumbersome, the repeatability is poor, and the equipment requirements are high. Moreover, due to the error in the average thickness measurement, the final volume estimation often has a negative growth.
