Abstract

The invention relates to a laboratory Limnoperna lacustris culture device and a method for culturing Limnoperna lacustris by using the same, and belongs to the field of Limnoperna lacustris research. The culture device comprises a culture pond, an internal baffle and an adsorption device, wherein the left sidewall of the culture pond is provided with a water inlet, and the right sidewall of the culture pond is provided with a water outlet; the internal baffle consists of a front baffle and a back baffle, and the adsorption device is arranged between the front baffle and the back baffle. In the culture stage, nutrients are added into the culture pond daily, the temperature of water is maintained at 22 plus or minus 2 DEG C, the flow rate of raw water in the culture pond is 0.1 to 0.2m / s, the concentration of dissolved oxygen in water is 2.2 to 3mg / L, the pH of water is controlled between 6.5 and 9, and water on the culture pond is replaced once every 10 to 14 days. The culture device provided by the invention is simple in structure, the culturing is easily realized under laboratory conditions, and an attachment device is favorable for attachment and growth of Limnoperna lacustris; the culture method is simple and feasible, the Limnoperna lacustris can be cultured under the laboratory conditions, and the better technical effects can be obtained.

Description

technical field

[0001] The invention belongs to the field of freshwater shellfish research, and in particular relates to a device for cultivating freshwater shellfish in a laboratory and a method for cultivating freshwater shellfish using the device. Background technique

[0002] With the long-distance water transmission project put into use, the problems of biological invasion and fouling in the water transmission system have gradually become prominent. "Biofouling" refers to the invasion of a large number of attached organisms into water transfer structures and related production equipment, with a density as high as 10,000~100,000 / m 2 , causing fouling to the surface of the structure, corroding the structure, and even blocking the pipeline, affecting the normal operation of the project. The freshwater shellfish of the Mytilidae species growing in southern my country has caused serious biofouling in water pipelines. These shellfish continue to attach, grow, and multiply in...
