First check valve is opened, and second one-way valve is closed, and second one-way valve prevents the seawater in vertical suction tube from passing through second one-way valve
Discharge；
In this way, the seawater in a part of external world can be made by second one-way valve, vertically during floating frame floats every time
Suction tube enters in corresponding observation channel with connecting tube, determines vertical pipeline lower part to constantly be pumped into extraneous seawater
Observation channel in；In this way, photographic device can take four different depths by carrying out shooting process to each observation channel
The ocean fish-egg of position carries out the monitoring of vertical distribution to ocean fish-egg（The locating height in the lower end of each vertical suction tube is different, tool
Body, which is said, is, the locating height in the lower end of first vertical suction tube in four vertical suction tubes is lower than second vertical suction tube
The locating height in lower end, the locating height in the lower end of second vertical suction tube are lower than height locating for the lower end of the vertical suction tube of third root
Degree, the locating height in the lower end of the vertical suction tube of third root is lower than the locating height in the lower end of the 4th vertical suction tube）, and pass through
Constantly extraneous seawater is pumped into the observation channel for determining vertical pipeline lower part, can also be effectively improved to fish of drifting about in water
The effective monitoring region of ovum.
Second, after a period of time has passed（Such as 3 weeks or 4 weeks）, the vertical distribution monitoring device of ocean fish-egg is recycled, is led to
Photographic device is crossed by the shooting process to each observation channel, the ocean fish-egg of four different depth positions is obtained, thus to sea
Foreign fish-egg carries out the monitoring of vertical distribution.
