Cephalopod high-density hatching bucket

Abstract

The invention discloses a high-density hatch bucket for cephalopods. The hatch bucket includes a circular breeding tank. A whole tank inflation device which can move in the breeding tank and perform inflation on a water body in the breeding tank for oxygenation is arranged in the breeding tank. The whole tank inflation device is provided with a horizontally arranged micro-porous tube. An annular inflation ring frame is composed of the micro-porous tube, vertical tubes and a floating frame tube, wherein the vertical tubes are connected to the two ends of the micro-porous tube, and the floating frame tube is located on the top. The inflation ring frame is connected with a floater. A winding prevention hose which can supply air to the micro-porous tube is connected to the floating frame tube and provided with a winding prevention device. A conical flow guide protrusion is arranged in the center of the bottom of the circular breeding tank. To-be-hatched egg granules of the cephalopods form intermittent circulation flow under the action of the conical flow guide protrusion in the center; compared with the prior art that intermittent circulation flow is formed by opening or closing an inflation pump, the high-density hatch bucket has higher reliability, and the service life of an inflator can be prolonged. The hatch bucket has the advantages of being good in oxygenation effect, low in usage cost, large in oxygenation section, high in effective oxygenation water body ratio, efficient and capable of saving energy and protecting an oxygenation motor.

Description

technical field [0001] The invention relates to a high-efficiency oxygen-increasing egg hatching container, in particular to a cephalopod high-density hatching bucket. Background technique [0002] When breeding and hatching fish, the requirements for water flow and dissolved oxygen are relatively high, especially for artificial hatching of fish eggs of some buoyant, semi-floating and sticky fish after debonding, it needs to be carried out in flowing water. , the speed of water flow and the amount of dissolved oxygen will directly affect the hatching rate of fish eggs. At present, the commonly used hatching buckets only adjust the dissolved oxygen supply by artificially controlling the water flow. If the water flow is too large, it will easily cause the seedlings to run away and damage the eggs and seedlings. If the water flow is too small, it is difficult to ensure the dissolved oxygen. to improve effectively. Prior art, such as the utility model patent of authorized anno...
