Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] Such as figure 1 Shown, a kind of bottom-sinking type centralized catcher that utilizes Man's needleless cuttlefish to drill cave habits includes floating frame 1 and some cuttlefish catchers 2.

[0030] The floating frame is provided with a floating block 1.2, a number of vertical support rods 1.3 and a number of supporting feet 1.1 for supporting the floating frame. The floating block of the floating frame is located above the floating frame. The supporting feet are located below the floating frame.

[0031] The squid catcher is in one-to-one correspondence with the vertical support rod.

[0032] Such as figure 1 , figure 2 As shown, the squid catcher includes a counterweight 3 , a squid catcher 4 , a trigger mechanism 5 , a connecting device 6 and an unlocking mechanism 7 .

[0033] Such as figure 2 , image 3 As shown, the s...

Abstract

The invention discloses a bottom sinking type centralized collecting device using hole entering habit of sepiella maindroni, and aims to provide a bottom sinking type centralized collecting device which can catch the individual sepiella maindroni, does not affect normal growth or propagation of the sepiella maindroni, can float up automatically after catching the sepiella maindroni, and thus facilitates actual catching operation. The bottom sinking type centralized collecting device using hole entering habit of sepiella maindroni comprises a floating rack, wherein the floating rack is providedwith a floating rack block, a plurality of vertical supporting rods, a plurality of supporting legs for supporting the floating rack and a plurality of sepiella maindroni catching devices; the supporting legs are used for supporting the floating rack and are positioned below the floating rack; the sepiella maindroni catching devices are in one-to-one correspondence to the vertical supporting rods; and each sepiella maindroni catching device comprises a balancing weight, a sepiella maindroni catching device, a triggering mechanism, a connecting device and an unlocking mechanism.

Description

technical field [0001] The invention relates to a trapping device, in particular to a bottom-sinking centralized catcher utilizing the habit of Mann's needleless cuttlefish drilling into caves. Background technique [0002] Squid is one of the four major marine products in my country (large yellow croaker, small yellow croaker, hairtail, and squid). The fishery catches a large amount, and the meat is delicious and nutritious. However, the quality of squid living in the sea is seriously affected by the destruction and pollution of the sea area ecological environment. . The needleless squid is a kind of squid. On the other hand, with the improvement of people's living standards, while the production and consumption of aquatic products have greatly increased, the quality of aquatic products has also attracted more and more attention. Therefore, research on whether the quality of squid is affected by pollution has gradually received attention. [0003] The current squid catche...
