Complete equipment for investigation of corbicula fluminea resources

Abstract

Complete equipment for investigation of corbicula fluminea resources comprises an image device and a fishing device, and is characterized in that the image device comprises a waterproof camera (1), an image transmission cable take-up and pay-off device (2) and an image display terminal (3); one end of an image transmission cable is connected with the waterproof camera (1); the other end of the image transmission cable is connected with the image display terminal (3); the waterproof camera (1) is used for observing the distribution condition of underwater corbicula fluminea before fishing so as to determine whether the distribution condition of the underwater corbicula fluminea meets the fishing condition or not; the fishing device is mainly composed of a fishing net cage (4), a pressing rod (5) and a dragging rope (6); the fishing net cage (4) is composed of a cage frame and a mesh body installed on the cage frame; the pressing rod (5) is fixed to the cage frame; the two ends of the dragging rope (6) are connected with the two sides of one face, not provided with the mesh body, of the cage frame; the lower bottom frame of one face, not provided with the mesh body, of the cage frame is additionally provided with spikes (8) inserted into river sludge conveniently. The complete equipment for investigation of the corbicula fluminea resources is simple and ingenious in structure, easy and convenient to operate, easy to implement and low in manufacturing cost.

Description

technical field [0001] The invention relates to a kind of aquatic technology, especially suitable for the investigation and research device of river clam (a benthic animal), in particular a complete set of device for investigating and fishing river clam resources. Background technique [0002] River clams are freshwater aquatic organisms that belong to the bivalves. Its delicious taste and high nutritional value are deeply loved by consumers in my country, Japan, South Korea and Southeast Asian countries. It is one of the important freshwater aquatic products exported in China. The shell of the river clam is medium in size, in the shape of a triangle with a round bottom. The shell surface is shiny, and the color varies with the environment, often brownish yellow, yellowish green or dark brown. The shell surface has rough ring ribs. Ligaments are short and protrude outside the shell. The hinge part is developed, the adductor muscle scar is obvious, and the mantle scar is ...
