A method for indoor artificial seedling cultivation of scorpionfish

Abstract

The invention relates to the technical field of aquaculture, in particular to an indoor and artificial sebastiscus marmoratus breeding method. A level-three variety-increasing breeding culture methodutilizing a conical flask water bath having a temperature-controllable heating function, a sunlight room cement pit with a water body of 0.7-1 m<3> and a shading film plastic-covered greenhouse cementpit with a water body of 150-180 m<3> and the shading rate of 60-70% is adopted for biological bait culture (algae and wheel animalcules), culture begins from the end of February to the beginning ofMarch each year, and open baits for sebastiscus marmoratus fry are cultured at the end of March; female sebastiscus marmoratus are captured from the end of March to the beginning of April, yolk fry isdelivered by adopting a low-water-level rich water fry-putting method adopting special fry delivering frames, the fry breeding salinity is controlled to be 17.5-19, and the temperature is controlledto 16-19 DEG C. The wheel animalcules serve as open baits, and the size and structures of bait individuals are gradually changed with the increase of splitting openings; dirt is sucked one time everyday, water change is performed one time, and the fry is bred into young sebastiscus marmoratus with the length of 3-40 mm by needing 50-60 days.

Description

Technical field [0001] The invention relates to the technical field of aquaculture and seedling cultivation, in particular to a method for artificial seedlings of the brown calamus. Background technique [0002] Sebastisucus marmoratus belongs to Scorpaeniformes Scorpaeniformes, Scorpaenidae, Sebastiscus, commonly known as scorpionfish and Shijiugong. It is distributed along the coast of my country, especially in the southern part of the East China Sea and the South China Sea, where it inhabits offshore rocky areas. It has a high release rate, fine meat, delicious taste, rich nutritional value, high economic value, and is a kind of warm temperature. The bottom ovoviviparous small economic fish; the adult body length of the brown calamus is 15-30cm and the weight is 100-300g; the brown calamus is generally 2-3 years old and mature, while the reproduction period of the brown calamus is generally in winter and spring. The two peak periods are from December to January and March to May...

Problems solved by technology

[0003] In recent years, many scientific research institutes, ocean universities and production units in my country have carried out some biological and ecological research on the scorpionfish, and studied the effects of bait and temperature on the early growth and artificial reproduction of the scorpionfish, salinity, Experiments on the influence of PH and temperature ecological factors on the embryonic development and larval growth of Scorpion scorpion; however, there is no report on a method of artificial breeding of Scorpion scorpion indoors

[0004] At present, the artificial breeding of fry mainly relies on catching natural fish species, which is difficult to meet the needs of breeding; at the same time, due to the continuous upgrading of marine fishery operating tools and the continuous increase in recreational fishing, overfishing has led to a sharp decline in its natural resources. Therefore, the development of It is very necessary to study the artificial seedling breeding technology of brown calamari, in order to achieve large-scale breeding and production, which not only meets the needs of the majority of farmers for seedlings, but also restores and protects natural resources through multiplication and release.
