Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0014] Such as figure 1 with figure 2 As shown, a method for overwintering in the northern part of the octopus broodstock, artificially constructed 30m 2 Short octopus broodstock breeding pond 2. The breeding pond 2 is equipped with water inlet 1 and water outlet. The water inlet 1 is higher than the water surface. The water outlet is provided with a drainage pipe 6 with an inner diameter of 150mm. The drainage pipe 6 extends into the pond 80cm and extends into the drain pipe in the pond. There are several water holes 8 with a diameter of 5mm on the top and side. Keep the seawater depth of about 1m in the pool. Spread a layer of sea sand 3 with a thickness of 10cm on the bottom of the pool; tie the aquaculture tank 4 into a string with 120 strands of polyethylene rope 5 Placed on the sea sand 3 at the bottom of the breeding pond 2, 14 per square meter. The br...

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 in strings 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 lower temperature 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 breeding technology, and specifically is a method for overwintering in northern octopus broodstock. Background technique [0002] The short octopus (Octopus ocellatus) belongs to the cephalopod and is a kind of small octopus, commonly known as the octopus. Widely distributed in the Bohai Sea, the Yellow Sea and the northern part of the East China Sea. Its meat is delicious and nutritious, which is popular with consumers and has high economic value. The fresh, dried and processed products of the octopus have broad domestic and overseas markets. They are mainly exported to South Korea and Japan. They are important export seafood products in northern my country. [0003] At present, as a new breed of northern octopus, its breeding broodstock mainly depends on natural fishing. Its harvesting and transportation process will cause damage to the breeding broodstock, and it is difficult to guarantee the quality of the bre...
