Problems solved by technology

At present, in the process of high-density and intensive artificial breeding of porphyra, due to its special ecological and physiological characteristics, it is easily affected by factors such as the water environment, nutritional conditions, and fry density of the fry, resulting in a low survival rate of the fry. There are large differences in the growth characteristics of the

Abstract

The invention provides an indoor cement-pool artificial breeding method for oplegnathus punctatus. The method comprises the following steps: (1) water-quality regulation and control: before hatched fish larvae are put, adding an EM probiotic preparation and natural alga cultivating pool water into a pool in each day; (2) pool entry: before the hatched fish larvae are put, distributing air stone ina transverse H manner, and putting the fish larvae in the pool, wherein the putting density is 13000-15000 fish larvae per cubic meter; (3) feeding management: feeding the fish larvae which are 20-40days old with baits including copepods and living mysis, and feeding the fish larvae which are over 30 days old with microencapsulated opening baits; (4) water change and illumination management: after the fish larvae are fed for 30-49 days, replacing water with 100%-150% of filtered seawater, and carrying out indoor illumination on the fish larvae which are 20-35 days old at 2500x-30001x, so asto realize light induced food intake; and (5) larvae outputting: transferring the larvae into a maritime net cage for breeding. According to the indoor cement-pool artificial breeding method, the growth quality of the fish larvae is improved, the death rate of the fish larvae is decreased, stress reaction of the fish larvae on a net cage breeding environment is reduced, and the survival rate of adult fish is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an indoor cement pond artificial seedling raising method for porpoise. Background technique [0002] Plegnathus punctatus (Oplegnathus punctatus) belongs to the genus Oplegnathus punctatus of the family Perciformes, and is commonly known as spot bream, black mouth, flower golden drum, etc. The body of the sapphire is dark brown with irregular black spots, the head is small and the mouth is short, the teeth are dense and sharp, the dorsal fin is short and hard, the front fin rays are prominently raised, the rear is shorter, and the trailing edge of the fin rays is truncated. shape. Widely distributed in North Korea, Japan, Taiwan Island of China, South China Sea, East China Sea, Yellow Sea and other sea areas, rarely form natural groups, there is no obvious peak fish season, and the output is small. Spotted sea bream has high edible and medicinal value, delicate meat, rich c...
