Embodiment Construction

[0017] As shown in Figure 1, it is an embodiment of a multifunctional sediment catcher of the present invention. The main components include a cylindrical body 2, a detachable sediment collection device 1, an exchangeable biological tray 3, and a free combination. Composition of the support system.

[0018] The cylindrical main body is a PVC round pipe 2 with a height of 70cm, an outer diameter of 20cm and an inner diameter of 18.5cm. A PVC ring 4 with a thickness of 0.8 cm is embedded in the inner pipe at 10 cm from the opening of the upper end of the PVC circular pipe 2 of the catcher, as a support frame of the biological tray 3 . A circle of grooves is set on the outer wall at the 12-18cm upper end opening of the PVC round pipe 2 of the catcher, for fastening the rope when hanging the catcher. A circle of grooves is placed on the outer wall at the bottom 4-6cm of the PVC round pipe 2 of the catcher, which is used to hang the weight to increase the stability of the catcher ...

Abstract

The invention is concerned with the combination depositing catcher, includes the catcher main body, the biology web in the catcher main body, the characteristic is: the catcher main body is round tube shape, the ratio of the catcher height and the opening outer diameter of the catcher is 4 to 5, sets the annular protrusion on the inner wall of the round tube, the biology web is on the annular protrusion. The top of the catcher main body is PVC round tube, the bottom is transparenc organic glass round drum depositing collecting equipment, sets internal thread at the bottom of the PVC tube, sets the external thread at the top port of the depositing collecting equipment, the bottom of the PVC tube and the drum depositing collecting equipment is the screw threaded connection, the depositing collecting equipment collocates the cover with internal thread. The catcher is collocated several stainless steel biology webs with different aperture.

Description

technical field [0001] The invention belongs to the technical field of on-site measurement tools for biological deposition rate in aquaculture ecology. Specifically, under field conditions, the biological sediment (feces and false feces) and the residual bait for cultivation are collected, and measured, A multifunctional sediment trap for calculating parameters of the ecophysiology of feeding of organisms. Background technique [0002] The theoretical guiding role of aquaculture capacity in aquaculture production has been more and more valued and recognized by managers and aquaculture producers. At the same time, in order to ensure the sustainable development of the aquaculture industry and the sustainable output of food, the coordinated development of aquaculture activities and the ecological environment is the top priority. The feeding physiological activity of cultured organisms is an extremely important parameter in the assessment of culture capacity. Therefore, accura...
