Abstract

The invention discloses an indoor wintering method of octopus parents in north, comprising the following steps: paving a layer of sea sand at the bottom of a culture pond, placing cultivation tanks instrings at the bottom of the culture pond, aerating the culture pond using an air pump via dispersed-air stone, keeping the water temperature of the culture pond not less than 10 DEG C, and placing mulluscs lower in living bodies such as quadrangle clams and short necked clams as well as small crabs for one time or many times. The method avoids the fatal damage on breeding parents caused by lowertemperature in winter in the north, provides rich octopus breeding parents by manpower and reduces the dependence on natural parents and damage to natural resources. The method ensures high cultivation density and survival rate, favorable economic benefit and simple method and is suitable for large and medium size cultivation units with wintering condition.

Description

technical field [0001] The invention belongs to aquatic broodstock cultivation technology, in particular to an indoor overwintering method for short octopus broodstock in the north. Background technique [0002] Short octopus (Octopus ocellatus) belongs to cephalopods, Octopus order, is a small octopus, commonly known as eight bands. Widely distributed in the Bohai Sea, the Yellow Sea and the northern part of the East China Sea. Its meat is delicious and nutritious, popular with consumers, and has high economic value. The fresh, dried and processed products of octopus have broad domestic and overseas markets, mainly exported to South Korea and Japan, and are important export seafood in northern my country. [0003] At present, short octopus is a new breed in the north, and its breeding broodstock mainly depends on natural fishing. The harvesting and transportation process will cause damage to the breeding broodstock, and it is difficult to guarantee the quality of the bree...
