Description

Marine squid trapping device

Technical Field

The invention relates to a squid trapping device, in particular to an offshore squid trapping device.

Background

Squids, also known as the sentence gong, the squid or the squid, are animals of the suborder Ophioglossoides of Tortosylidae of the phylum mollusca. The body is slender and long-cone-shaped, and dozens of them touch the wrist, two of them are longer. The front end of the wrist touch is provided with a sucking disc, a horn-shaped toothed ring is arranged in the sucking disc, and the wrist touch is used for entangling and swallowing food when the food is caught. They are favored to gather, especially in the mating and spawning period in spring and summer. Squid is generally captured in a squid fishing mode, and squid fishing devices are various, but most of the existing squid fishing devices are poor in capturing effect, a squid fishhook can only float along with water flow after entering water, and the capturing range is small.
