Breeding method for promoting reproduction of male parent fish of hippocampus erectus during production stopping

Abstract

The invention provides a breeding method for promoting reproduction of male parent fish of hippocampus erectus during production stopping. The breeding method comprises the following steps: A, terminating pairing; b, concentrated recuperation: concentrating the male hippocampus japonicus which is stopped in production in a small water body culture container for culture, wherein the culture density is 0.5-2 / 10L, and adopting a running water culture mode; c, nutrition enhancement: feeding live shrimps every day in the breeding period for nutrition enhancement; d, mutualism behavior induction: after breeding for a period of time, adding normal, pregnant and fertile male parent fish of hippocampus erectus with marks into the breeding container of the hippocampus erectus during production stopping to induce the male hippocampus erectus during production stopping to have mutualism behaviors; and E, identifying reproduced male hippocampus. By the adoption of the reproducing breeding method, the reproducing rate of the male parent hippocampus erectus during production stopping is increased, the reproducing rate is increased to 60% or above from traditional self-recovery of less than 20%, the breeding efficiency of the parent hippocampus erectus is greatly improved, and the management and maintenance cost of the parent hippocampus erectus is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of seahorse culture, and in particular relates to a culture method for promoting the rebirth of gray seahorse male broodstock that has been discontinued. Background technique [0002] Seahorse is a traditional precious Chinese medicine, known as "animal ginseng", and a rare ornamental fish, enjoying the reputation of "marine spirit". In the past ten years, my country's seahorse breeding technology with the gray seahorse (Hippocampus erectus) as the dominant species has developed rapidly, but large-scale production still faces some problems. One of the more prominent problems is the low breeding efficiency of broodstock. Seahorses are animals that are conceived by males. In the early breeding practice, it was found that after several pregnancies and births of male seahorses, the brood sacs of some male seahorses will harden and shrink, some brood pouches will bulge on both sides, and some The endothelium of ...

Problems solved by technology

Due to the lack of an effective solution, the breeding unit can only fill the seed vacancy caused by the discontinued broodstock by updating and replacing the broodstock. However, the broodstock that have been discontinued are often helpless, resigned to their fate, and hope that they can resume production on their own

In fact, in the absence of human intervention, the proportion of discontinued male seahorses that resume production on their own is quite low, less than 20%.

Therefore, in order to support the sufficient output of seedlings, breeding units need to reserve and manage a large number of broodstock, which will inevitably greatly increase manpower, material and financial resources, resulting in high breeding costs
