Simulated ecological breeding water tank for fishes laying demersal eggs or floating eggs

Abstract

The invention discloses a simulated ecological breeding water tank for fishes laying demersal eggs or floating eggs. The breeding water tank comprises water tank bottom plates, wherein the water tank bottom plates are trapezoidal and are horizontally placed, the upper surfaces of the water tank bottom plates are downwards inclined from the water inlet end to the water outlet end, the front sides and the rear sides of the upper surfaces of the water tank bottom plates are both provided with water tank side plates in a vertical state, the two ends of each water tank side plate are flush with the end faces of the adjacent water tank bottom plates, a plurality of flow generation cross beams are arranged on the upper surfaces of the water tank bottom plates at intervals, the two ends of each flow generation cross beam are connected with the inner surfaces of the corresponding water tank side plates, and a plurality of flow generation round protrusions arranged at equal intervals are arranged on the upper surfaces of the water tank bottom plates on the two sides of each flow generation cross beam. According to the breeding water tank, in the using process, the device can be used for spawning and breeding of fishes laying demersal eggs or floating eggs in the device, the problems that the surfaces of the fishes laying demersal eggs are injured, and the breeding effect is affected due to the fact that fish eggs are deposited at the bottom of the breeding water tank can be solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to an ecologically imitative breeding tank for fish that lay sinking eggs or floating eggs. Background technique [0002] Nowadays, in the process of artificial breeding, fish need to reproduce, and the breeding process is generally carried out by artificial injection of oxytocin hormone and artificial oxytocin insemination. But the reproduction of some fish has been difficult to carry out under artificial conditions, or artificial breeding procedures are cumbersome. In order to further reproduce under artificial control, biomimicry reproduction is a better way. By creating the flow velocity, flow state and substrate conditions required for fish reproduction, the biomimetic reproduction can induce fish to reproduce naturally under ecological conditions, which can greatly save labor and cost. This kind of bionic artificial breeding tank satisfies the breeding of sinking egg-p...
