Floating roe collecting device and using method thereof

Abstract

The invention discloses a floating roe collecting device and a using method thereof, and relates to the technical field of roe hatching and collecting equipment. The floating roe collecting device comprises a water sprayer and a sliding rail, the water sprayer comprises a water sprayer body, a water pump and a first nozzle, the water pump and the first nozzle are both installed on the water sprayer body, one side of the sliding rail is used for being connected with a fishing net, the other side of the sliding rail is slidably connected with the water sprayer body, the water pump communicates with the first nozzle, and the first nozzle inclines upwards and faces the fishing net. The first nozzle which is inclined upwards and faces the fishing net is arranged on the water sprayer and can wash roes hung on the fishing net, so that the roes are impacted back to the water surface, and the roes are prevented from death due to dehydration.

Description

technical field [0001] The invention relates to a floating egg collecting device and a using method thereof in the technical field of fish egg hatching and collecting equipment. Background technique [0002] At present, in some high economic value deep-sea cultured fish farms, it is often necessary to set fish raft cages in natural sea areas for cultivation. For fish breeding that produces buoyant fish eggs, during the fish spawning period, the buoyant eggs are easily affected by the tide and hang on the fishing net, and once the fish eggs are dehydrated and exposed to the sun for a long time, it is easy to cause the death of the fish eggs. Therefore, at present, during the spawning period, farmers need to check the fishing net frequently and scrape off the fish eggs hanging on it, which greatly increases the labor intensity of the farmers. [0003] In addition, buoyant eggs often gather at the edge of the fishing net, and it is easy to damage the buoyant eggs during collec...

For fish breeding that produces buoyant fish eggs, during the fish spawning period, the buoyant eggs are easily affected by the tide and hang on the fishing net, and once the fish eggs are dehydrated and exposed to the sun for a long time, it is easy to cause the death of the fish eggs

Therefore, at present, during the spawning period, farmers need to check the fishing net frequently and scrape off the fish eggs hanging on it, which greatly increases the labor intensity of the farmers.

[0003] In addition, floating eggs often gather at the edge of the fishing net, and it is easy to damage the floating eggs when collecting, so they must be collected with great care, resulting in an inefficient collection process
