The invention discloses a slug catching device which comprises a ship body, two symmetrically-arranged telescopic connecting pieces are arranged at the tail of the ship body, one ends of the two telescopic connecting pieces are connected with the ship body through a mounting main body, and the other ends of the two telescopic connecting pieces are jointly connected with a roller through two symmetrically-arranged connecting main bodies. A plurality of groups of barbs are arranged on the roller, a collecting mechanism is arranged between the two telescopic connecting pieces, the collecting mechanism is matched with the roller, and a conveying mechanism matched with the collecting mechanism is arranged on the collecting mechanism. A roller fishing mode is adopted to replace a traditional bottom trawl fishing mode, so that the slugs cling to the bottom surface to crawl and live and low in height can be efficiently fished, the slugs of different sizes can be completely fished, and the fished slugs can be conveniently processed and treated in the follow-up process; and manual fishing can be replaced in the no-fishing period, the labor cost is reduced, and the fishing efficiency is improved.
本发明公开了一种经氏壳蛞蝓的捕捞装置,包括船体,所述船体的尾部设有两个对称设置的伸缩连接件,两个所述伸缩连接件的一端均通过安装主体与船体连接,且两个伸缩连接件的另一端通过两个对称设置的连接主体共同连接有滚筒,所述滚筒上设有多组倒刺,两个所述伸缩连接件之间设有收集机构,且收集机构与滚筒匹配设置,所述收集机构上设有与收集机构匹配设置的输送机构。本发明采用滚筒捕捞的方式代替传统的底拖网捕捞能够对于紧贴底面爬行生活且体高很低的经氏壳蛞蝓进行高效捕捞,且能够对不同体积的经氏壳蛞蝓进行完整捕捞,便于后续对捕捞到的经氏壳蛞蝓进行加工处理,且能在禁渔期内替代人工捕捞,降低人力成本,提高捕捞效率。
