Description

Technical Field

[0001] The utility model relates to the technical fields of marine biological resource investigation, seaweed field and fishery resource protection, in particular to a double-cavity hammer-shaped net cage which is easy to capture cephalopods. Background Art

[0002] There are more than 700 species of Cephalopoda, including nautilus, squid, squid, octopus, etc. The body is bilaterally symmetrical. The head is well-developed, with a pair of well-developed eyes on both sides. Part of the foot becomes the arm, which is located around the head mouth. The mantle muscles are well-developed, and the left and right sides are fused to form a sac-like mantle cavity, which contains the internal organs. The skin on the sides or back of the mantle extends into fins, which can swim by the movement of the fins. The shell is generally wrapped in the mantle, which degenerates into a keratinous or calcareous inner bone called the sea cucumber sheath, which can be used as medicine. The nervous system is relatively centralized, and the brain ganglia, foot ganglia and visceral ganglia combine to form a well-developed brain, which is surrounded by cartilage. The heart is well-developed. The sexes are different.

[0003] However, existing net cages are inefficient in catching cephalopods. Utility Model Content
