Embodiment Construction

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

[0014] like figure 1 and figure 2 Shown, a kind of short octopus artificial pond cultivation method adopts artificial pond mariculture mode, pond 1 seawater depth is 1.8m, uses 120 watts of power cultivating water machine 6 to pond seawater oxygenation, 6 units per hectare, guarantees that oxygen content is in 6mg / L or more. Adopt natural water aquaculture, and the daily exchange rate of seawater in the pond is 10%. An escape-proof net 3 is set at the water inlet 2 and the drain of the pond, and the screen mesh 3 mesh number is 10 mesh. By polyethylene rope 5, culture tank 4 is placed in a string on the bottom of pond 1, with an average of 18 per square meter. Described culture tank 4 is a short octopus habitat shelter, and it is a kind of pottery pot, and the inner diameter of the tank mouth is 5cm , the outer diameter is 7cm, the pottery...

Abstract

The invention discloses a method for breeding octopus in a man-made pond, comprising the following steps: using a sea breeding manner in a man-made pond with the seawater depth of the pond being 1.5-2m, and oxygenating for the seawater with an oxygenating device; placing a breeding tank at the bottom of the pond by a polyethylene rope with a number of at least 15 per square meter; placing seedlings that are at least 3 cm long in the pond with a breeding density of 10-15 per square meter; 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 according to the breeding density and the ingestion intensity. The method improves the pond breeding environment, satisfies the burrow habit and the requirement ofbait nutrition, changes the habit of cannibalism and improves the survival rate, the growth speed and the economical benefit of the octopus.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for cultivating short octopuses in artificial ponds. 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, as a new breed in the north, grows fast and can reach a product size of more than 60g in half a year, and is favored by farmers. But, because it has the habit of living in caves and killing each other, it greatly limits its large-scale cultivation. In ...
