Embodiment 1

[0018] Embodiment 1: a kind of artificial seedling raising method of porphyra, comprises the following steps:

[0019] (1) Design of the nursery pool: the nursery pool is circular with a conical bottom in the middle, and the area of ​​the pool is about 80m 2 , the water depth is 1.5m, and the conical bottom is the position of the drain outlet. There are 3 water inlets with the same water inlet direction. 2 small underwater atomizing aerators are placed at the bottom of the pool, and the aerators are connected to the liquid oxygen tank to add oxygen. Pressure, spray atomized microbubbles from the bottom of the water through the microporous aeration tube for uniform oxygenation, and the oxygenation direction is consistent with the water inlet direction;

[0020] (2) Design of the hatching tank: the specification is 5m × 5m × 1.2m. There is a rope tied to the bottom of the hatching tank. There are several semicircular bolt holes on the bottom and inner wall of the nursery tank, a...

Embodiment 2

[0027] Embodiment 2: a kind of method for artificial breeding of porpoise, comprises the following steps:

[0028] (1) Design of the nursery pool: the nursery pool is circular or nearly circular, with a conical bottom in the middle, and the area of ​​the pool is about 65m 2 , the water depth is 1.5m, the conical bottom is the position of the drain, and there are two water inlets. The tank pressurizes the oxygen, and sprays atomized microbubbles from the bottom of the water through the microporous aeration tube for uniform oxygenation, and the oxygenation direction is consistent with the water inlet direction;

[0029] (2) The hatching tank adopts the following design: the specification is 5m × 5m × 1.2m, a rope is tied to the bottom of the hatching tank, and several semicircular bolt holes are set on the bottom and inner wall of the nursery tank, and the rope passes through The bolt hole is directly connected to the fixing device on the bank of the nursery pond, and a layer o...

Abstract

The invention discloses an artificial breeding method for oplegnathus punctatus, and relates to the technical field of fish aquatic organism culture in aquaculture. The method comprises the steps of nursery pond water quality condition control, fertilized egg feeding into a pond, fry breeding and feeding management, water quality management during the fry breeding and feeding period, seedling pond division, seedling emergence and the like. Compared with the prior art, an incubation tank special for artificial breeding is designed, nursery pond water inflowing and drainage and oxygenation facilities are improved, the nursery pond water quality conditions are strictly controlled, scientific and reasonable bait casting and operation management are carried out in different stages of fry breeding of the oplegnathus punctatus, the mixed feed casting mode is improved, and the stable high yield of artificial breeding of the oplegnathus punctatus is achieved.

Description

technical field [0001] The invention relates to the technical field of fish aquatic organism cultivation in aquaculture, in particular to an artificial seedling raising method for porphyra. Background technique [0002] Spotted parrotfish, belonging to the order Perciformes, the genus Scorpidae, is commonly known as spotted parrotfish, flower golden drum, black golden drum, and its English name is Spotted parrotfish. Distributed in North Korea, Japan, Taiwan Island, South China Sea, East China Sea, Yellow Sea and other sea areas, it is a middle and lower layer fish in the coastal waters of temperate tropics. In natural sea areas, the natural resources of this fish are scarce, and they are often obtained by fishing. They rarely form natural groups, there is no obvious peak fish season, and the output is very small. Spotted sea bream has high edible and medicinal value, delicate meat, rich collagen, unique taste, rich in various amino acids and unsaturated fatty acids, and ha...
