Description
Technical field
The present invention relates to a kind of offspring seed cultivation method, be specifically related to a kind of plan order cuttlefish offspring seed cultivation method, belong to cuttlefish cultural technique field.
Background technology
Intend order cuttlefish metastomium peltate, trunk is about and is wide 2 times of trunk; Some shape spots of trunk back of the body tool are mixed with many thinner horizontal stripes.Fin broad, Breadth Maximum be slightly less than trunk wide 1/4th, be positioned at the full edge in metastomium both sides, separate in the rear end.
Intend the order cuttlefish and be distributed in the Indian Ocean---the field, Western Pacific, often inhabit the place of the depth of water 15 ~ 100m, its build is bigger; Breeding cycle is short, and growth is rapid, delicious meat; Protein content is high, and the comprehensive utilization scope is wide, is the higher improved seeds of China's South Sea economic worth.
At present domesticly in succession correlative study has been carried out in aspects such as the habit of Sepiella maindroni and golden cuttlefish and cultural method, still less for the research of plan order cuttlefish, especially aspect propagating artificially.
Sepiella maindroni artificial propagation and cultural technique to break through in 2003, at present in Zhejiang, ground such as Fujian, Hebei form certain breed scale, this achievement obtains National Bureau of Oceanography's ocean innovation second prize.Golden cuttlefish seed cultural technique obtained to break through in 2011, had formed several demonstrations in Shandong and had promoted point, and this achievement obtains National Bureau of Oceanography's innovation achievement prize first prize.
Propagating artificially under the condition, Sepiella maindroni is through individual month growth of 4-5, and body weight is the 100-200 gram, and golden cuttlefish is through individual month growth of 8-10, and body weight is about 500 grams.Compare with these two kinds, it is faster to intend order cuttlefish growth rate.Can reach 4 kilograms of body weight in 1 year, economic benefit obviously is superior to preceding 2 kinds.If with long 25 centimeters of squid body, body weight 500 grams is the listing specification, Sepiella maindroni will be cultured more than 1 year, and golden cuttlefish is taken 8 months, only takes 3-4 month and intend the order cuttlefish.The breed risk of intending the order cuttlefish is starkly lower than Sepiella maindroni and golden cuttlefish.
The young of intending the order cuttlefish is obviously greater than Sepiella maindroni and golden cuttlefish, and to dwell the end of be main, and its breeding condition and bait are also inequality.The open-mouthed bait of intending the order squid larva is optimum with the acanthosoma and the post larval of shrimps; Intending the order cuttlefish is to live under the tropical ocean environment; Its young environment of growing seedlings can carry out at 39 ℃, and Sepiella maindroni and golden cuttlefish mainly live in the seawater of temperate zone, and their breeding ecological condition also difference is very big.Therefore, its artificial raise seedling method is also different with Sepiella maindroni and golden cuttlefish with technology.So propagating artificially of order cuttlefish intended in research and development, good market prospects arranged, and can effectively evade the breed risk, has very important significance.
