Embodiment 1
[0022] The brown calamari factory seed cultivation method, it has the following steps:
[0023] ①Intensive breeding of broodstock: select broodstock to be raised in cages with rafts, feed fresh miscellaneous fish, and feed broodstock enhanced feed 2 months before calving to strengthen cultivation;
[0024] The enhanced feed for broodstock contains 4 parts of unsaturated fatty acids and 1 part of multivitamins by weight; the unsaturated fatty acids are linoleic acid, linolenic acid and arachidonic acid, and the ratio is 1:1:1 by weight; the multivitamins Contains 1.4 parts of vitamin A and 1.2 parts of vitamin D in parts by weight 3 , 18 parts vitamin E, 1.4 parts vitamin K 3 , 0.8 parts of vitamin B 1 , 0.8 parts of vitamin B 2 , 0.8 parts of vitamin B 6 , 1.2 parts vitamin B 12 , 9 parts of niacin, 3 parts of pantothenic acid, 0.2 parts of folic acid, 2 parts of biotin, and 50 parts of hyaluronic acid.

Embodiment 2
[0042] The brown calamari factory seed cultivation method, it has the following steps:
[0043] ① Intensive cultivation of broodstock: select broodstock to be raised in cages with fish rafts, and feed fresh miscellaneous fish, and feed broodstock enhanced feed 2 months before calving to strengthen cultivation; the ratio of broodstock enhanced feed is the same as in Example 1.
[0044] ② Hatching and littering: move the broodstock in step ① into the hatching net cage set in the littering pond for littering one week before the littering, and continue to feed the fortified feed; the daily water change in the pond is 400%, and the water temperature is maintained Keep it at about 17°C, keep the salinity at about 17‰, and keep the pH at about 8.3. Inflate with normal air volume, supplemented by low light; use chorionic gonadotropin (HCG) for fish at a dose of 1000IU / kg to induce labor. 20 hours after artificial induction, inflate 3 times with instantaneous large air volume to ripen ...

Abstract
The invention discloses a sebastiscus marmoratus industrializing young fish rearing method, comprising the steps of ripe fish intensive rearing, hatching and spawning, larval fish rearing and juvenile fish feeding. Compared with the prior art, the method has advantages that ripe fish fortified feed is applied, so that sufficient nutrition is stored for the ripe fish spawning, thus effectively improving the quantity and quality of the spawning; large amount of gas are filled instantaneously before the spawning, thus having an obvious maturity accelerating action on the ripe fish, so that largeamount of ripe fish can spawn nearly in the same time interval after the artificial induced spawning, therefore, management is convenient and the productivity is effectively improved; the matched breeding density is adopted in different ages in days of the larval fish, thus efficiently reducing resource waste; various factors in the water body can be correctly controlled and cultured during the whole rearing process, and environmental and nutritional threats suffered by the larval fish can be reduced, therefore, the spawning of the ripe fish under the manual control and the growing development from the larval fish to the juvenile fish can be realized normally; in addition, the spawning quantity is large and the survival rate of young fish rearing is high, thus ensuring that healthy and high-quality young fish of sebastiscus marmoratus is reared.
Description
technical field [0001] The invention relates to a technology for raising seedlings in aquaculture, in particular to a method for cultivating industrialized seedlings of scorpionfish. Background technique [0002] At the end of the 20th century, due to worldwide overfishing, fish stocks in the ocean continued to decline. In order to meet people's demand for marine aquatic products, countries all over the world are paying more and more attention to the development of artificial seawater aquaculture. In my country, mariculture, known as blue agriculture, is an important part of large-scale agriculture and occupies an important position in the national economy. The development of seawater seed cultivation technology is a prerequisite for the development of seawater aquaculture. [0003] The brown calamari belongs to the order Scorpioformes, the family Scorpionidae, and the genus Calamus. There are not many species in this genus. There are 3 species in the coasts of China and...
