Problems solved by technology

For bivalve molluscs as epifauna, such as mussels, oysters, scallops, etc., because the methods and devices for measuring their biodeposition are relatively easy to design, there are currently ready-made methods and devices for measuring them in the world. However, for bivalve molluscs as infauna or buried animals, such as clams and cockles, they are usually buried in the sediment, and there is no field measurement of this kind at home and abroad. Method and apparatus for animal biodeposition

Embodiment 1

[0021] The measuring device is mainly made of PVC material, including a drum 1 and a round tube 2. One end of the round tube 2 is fixedly connected to the drum 1 by screws, and the middle and lower part of the round tube 2 is provided with a bracket 4 for placing a small cup 3. 9 PVC small cups 3 are placed on the top, and gaps are left between adjacent small cups 3 (see figure 1 ). Wherein drum 1 and round tube 2 internal diameters are 15 centimetres, and height is respectively 60 centimeters and 10 centimeters, and total depth is 70 centimeters, and small cup 3 is deep 5 centimeters, and the vertical distance of small cup 3 tops and the outer wall top of round pipe 2 is 3 cm; the top of the round pipe 2 is provided with a nylon mesh (the mesh is 1 cm), and the small cup 3 is covered with fine sand; the round pipe is tied with a string, and the other end of the string is tied with a float 5, and the float 5 exposed to the sea 6;

Abstract

The invention relates to an experimental technology of marine animal ecology, in particular to an on-site measurement method and a device for biological sedimentation of buried double-shell shellfishes. The on-site measurement method for biological sedimentation of buried double-shell shellfishes is that: 1) the buried double-shell shellfish organisms are buried in a container containing the sand, one end of a water inlet and outlet pipe of the animals is upward buried in the sand as an animal experiment group; at the same time, the invention is provided with a control group which only arranges the sand in the container and does not arrange the experimental animals; 2) the container with the organisms is fixed in the marine culture environment to be cultured for 4 to 5 days; 3) all the devices are taken out, the sediments are collected, the invention adopts a siphon method to absorb the marine water which is covered on the sediments, and then the desalination and drying are carried out; 4) the biological sedimentation rate (BDR is equal to (Ds - Dc) divided by (N multiplied by t))o is calculated; by adopting the invention, the ecological habits of the buried double-shell shellfish organisms are given full consideration and the biological sedimentation of the buried double-shell shellfishes can be accurately measured on-site.

Description

technical field [0001] The invention relates to the experimental technology of marine animal ecology, in particular to a method and a device for measuring the biological deposition of buried bivalve molluscs on the spot. Background technique [0002] As filter-feeding animals, bivalve molluscs have a strong ability to filter water, and can increase the flux of suspended particulate matter from the water column to the bottom environment through filter-feeding and biodeposition, material and nutrient cycling and energy flow in coastal marine ecosystems plays an important role in. Some of this organic matter is absorbed by the shellfish and the rest is excreted in the form of fecal pellets or pseudofeces. Feces and pseudofeces are collectively referred to as biodeposits, and the process by which this material settles to the bottom of the ocean floor is known as biodeposition. In situ measurement of bivalve biodeposition has become an important tool for ecologists to study the...
