On.
The specific works of the fixed point fish-egg auxiliary monitoring device of the present embodiment are as follows:
As shown in Figure 1, launching fixed point fish-egg auxiliary monitoring device into specified sea area.
Tripping sleeve utilizes the fluctuation of wave, constantly float up and down (when sleeve floating block is in wave wave crest, tripping sleeve
Rise to high point;When sleeve floating block is in wave trough, tripping sleeve drops to low spot);
During tripping sleeve is moved up along fixed vertical sleeve, the first check valve prevents the underwater stream in tripping sleeve, thus outer
The seawater on boundary will enter fixed vertical sleeve by crossing water through-hole, and fixed vertical set will be entered by crossing water through-hole by forming extraneous seawater
The water flow of cylinder;In this process, extraneous seawater will pass sequentially through each attachment net cylinder, and seawater will drive water in this process
Most fish-egg in the fish-egg of middle floating will be attached in attachment net cylinder;
In tripping sleeve along fixed vertical sleeve folding process, the first check valve is opened, and second one-way valve is opened, vertical because depending on
Water in sleeve is hardly extruded, i.e., the water flow that the water in vertical sleeve is outflowed by crossing water through-hole will not be generated, to keep away
The fish-egg for exempting to be attached in attachment net cylinder is washed disengaging.
In this way, the fish-egg that can effectively improve in the seawater near active capture type fish-egg auxiliary device is attached to attachment
Adhesive rate in net cylinder, thus the case where more reliably reacting the fish-egg quantity in the seawater.
After a period of time, such as after two weeks, fixed point fish-egg auxiliary monitoring device is lifted, is taken out, by attachment net cylinder
Fish-egg, research and analysis is carried out to the oviposition situation in fish spawning ground.
