Industrialized comprehensive breeding method for apostichopus japonicus Selenka and octopus vulgaris Cuvier

Abstract

The invention relates to an industrialized comprehensive breeding method for apostichopus japonicus Selenka and octopus vulgaris Cuvier. The method comprises the steps that an indoor industrialized breeding pond and a shelter in the pond are built; the octopus vulgaris Cuvier is put into the pond, wherein seedlings of the octopus vulgaris Cuvier are put into the indoor industrialized breeding pondand fed with fresh and live baits; the apostichopus japonicus Selenka is put into a pond, wherein when the outdoor water temperature exceeds 22 DEG C, 20-50 g of the apostichopus japonicus Selenka istransferred into the indoor industrialized breeding pond where the octopus vulgaris Cuvier is added from the outdoor breeding pond; the octopus vulgaris Cuvier and the apostichopus japonicus Selenkaare bred, wherein the weight of the octopus vulgaris Cuvier is increased by 10-15 times to reach the commercial specification of 1,500-2,000 g through 3-4 months of breeding in the indoor industrialized breeding pond; when the outdoor water temperature is lower than 22 DEG C, the apostichopus japonicus Selenka is put back to the outdoor breeding pond. According to the method, biological habits that the octopus vulgaris Cuvier and the apostichopus japonicus Selenka do not struggle for feed, the shelter is shared, the baits are complementary without competition, and the suitable growth temperature and light intensity are consistent are fully utilized, conditions suitable for the growth of the octopus vulgaris Cuvier and the apostichopus japonicus Selenka are provided in an artificially-controllable environment, and the utilization rate of the industrialized breeding ponds is effectively increased.

Description

technical field [0001] The invention relates to a method for industrialized comprehensive cultivation of eel octopuses and belongs to the field of aquaculture. Background technique [0002] Sea cucumber (Apostichopus japonicus Selenka), also known as imitation sea cucumber, is an important marine aquaculture economic species and a key industry of high-efficiency ecological agriculture. Its strong development has led to the adjustment of fishery structure and the increase of fishermen's employment income, which has produced huge economic, social and ecological benefits. [0003] The true octopus (Octopus vulgaris Cuvier) is a warm-temperate species, distributed in the seas south of Zhejiang in my country, and Zhejiang, Fujian, and Guangdong have a large output. Octopus is a large octopus with tender and delicious meat and rich in protein. It is a good seafood and tonic. It is mainly exported to Japan and South Korea. It is an important export aquatic product. Owing to the f...

AI Technical Summary

Problems solved by technology

Except for temperature, octopus and japonicus have similar or complementary biological learning in the following five aspects: ① Both species need shelter, and the shelter can be shared; ② There is no competition between the two species for bait, and octopus The feces of the octopus and the bait (clams) of the octopus are good bait for sea cucumbers; ③ Both species like dark environments; ④ Although the octopus is a ferocious carnivore, the octopus does not feed on the sea cucumber; ⑤ two All species have high economic value, and the cost of breeding any one species alone is relatively high
