Abstract

The invention provides an artificial breeding method for diodon hystrix. The artificial breeding method comprises the following steps: parent fish sourcing and screening; parent fish intensive culture; parent fish induced spawning, and artificial hatching. According to the artificial breeding method provided by the invention, nutrient enrichment is performed on parents of the diodon hystrix, and process conditions including temperature, salinity, dissolved oxygen, pH value, oxygenation power, ammonia nitrogen and nitrite-nitrogen cooperate harmoniously, gonads of the parents can develop and mature under artificial breeding conditions; and through artificial induced spawning and hatching, a large number of fertilized ova are obtained and are artificially hatched. By employing the artificialbreeding method, the spawning rate of the parent fishes is high, the fertilization rate and the hatching rate of the fertilized ova are high; and the vigor of newly-hatched fish larvae is good, and the needs of large-scale breeding of diodon hystrix fingerlings can be met.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial breeding method of pufferfish. Background technique [0002] Chinese name: Porcupine pufferfish; English name: Porcupine pufferfish; Latin scientific name: Diodon hystrix. The dense-spotted pufferfish belongs to the class of ray-finned fishes, the order of pufferiformes, and the family of pufferidae. Distributed in subtropical waters of the world's oceans. The type locality of this species is India. When attacked, it will inhale sea water to swell its body into a ball, and erect spines to prevent the enemy from swallowing. Carnivorous, mainly feeds on benthic animals, poisonous. The dense-spotted spinyfish can reach a length of 91 centimeters. The body is short and wide, the mouth is small, and the upper and lower jaws in the mouth each have a well-developed tooth plate. Except the lip and caudal peduncle are densely covered with strong spines specialized ...
