Energy-saving roe hatching barrel

Abstract

The invention relates to the technical field of fry and fingerling breeding, and discloses an energy-saving roe hatching barrel which comprises a hatching barrel body, wherein a filter screen is fixedly connected to the top end of the hatching barrel body, an outflow frame located below the filter screen is movably clamped to the top end of the outer side of the hatching barrel body, one side of the bottom end of the outflow frame is fixedly connected with a water flowing opening, one side of the hatching barrel body is fixedly connected with a fish larva opening, the inner wall of the hatching barrel body is in threaded connection with a roe containing disc, and the top end of the roe containing disc is fixedly connected with a water outlet net. Through the height difference of water passing pipelines, the energy consumption of water flowing into the bottom end of the hatching barrel body is reduced, through the shape setting of the roe containing disc, the roe stacking height on the outer side of the top end of the roe containing disc is reduced, the roes can not be directly impacted by water flow, the action track of the roes is stable after swirling flow is formed in the hatching barrel body, therefore, collision among the roes is reduced, surface damage of the roes is reduced, and the hatching rate of the roes is increased.

Description

technical field [0001] The invention relates to the technical field of fry and fingerling breeding, in particular to an energy-saving hatching tank for fish eggs. Background technique [0002] Nowadays, the aquaculture industry continues to develop following people's demand. In order to reduce the cost of aquaculture and ensure the supply of fish and aquatic products, by improving the success rate of fish egg hatching and ensuring the survival rate of fish eggs hatched into fry, fish egg hatching buckets are usually used. For hatching fish eggs, about 20 degrees is the ideal hatching temperature when hatching, and the temperature of the water body is controlled by circulating heating. During the use of the hatching bucket, through its conical bottom and the conical top downwards, the water After the fish eggs are put in, the fish eggs gather inside the conical bottom, and the heated water flow enters from the cone at the bottom of the barrel, so that the fish eggs are scatte...
