Abstract

The invention discloses an artificial ripening cultivation method for sea horse parent fish, which belongs to the technical field of aquaculture. The artificial ripening cultivation method comprises the following steps of: catching mature sea horses from a sea area, and cultivating the sea horses in a cultivation pool with gulfweed or eucheuma, wherein the male-female ratio of the sea horses is 1:(1.1-1.4), and the density of the released sea horses is 25 to 30 per cubic meter; and in the cultivation process of the sea horses, feeding quality baits, South American white larval shrimps, for two times each day, and performing daily management on the sea horses by a management method of changing water through convection, siphoning dirt on the bottom of the pool and aerating for 24 hours. The method can be used for maximally simulating the ecological environment conditions of the natural sea area in which the sea horses live, reducing diseases, and promoting the sea horses to mature and reproduce in advance and improving the reproduction times and quantities of the sea horses through casting suitable hangers-on, feeding the baits with rich nutrition and steady sources and providing environment conditions suitable for gonad mature of the sea horses according to the law of life and feeding habits of the sea horses.

Description

technical field [0001] The invention relates to an artificially enhanced maturation-promoting cultivation method for broodstock in the artificial breeding process of seawater economic fish, in particular to an artificial maturation-promoting cultivation method for seahorse broodstock, which belongs to the field of aquaculture. Background technique [0002] For many aquatic economic animals, in the process of gonad development, maturation and reproduction, nutrition plays a decisive role in the growth and development speed of reproductive cells, and light and water temperature are also necessary external environmental conditions for aquatic economic animals to complete their reproductive activities. The gonads mature and reproduce only when the effective accumulated temperature in the natural environment reaches a certain level. For aquatic economic animals that have reached sexual maturity, if the temperature does not reach the temperature required for spawning, they cannot ...
