Ecological culturing method of young octopus variabilis

Abstract

The invention discloses an ecological culturing method of young octopus variabilis. The ecological culturing method comprises the following steps of 1, putting a net cage into an indoor cement pool, putting cladophora into the net cage and uniformly spreading the cladophora; 2, putting large corophium into the net cage and uniformly spreading the large corophium; 3, putting the hatched young octopus variabilis into the net cage to be cultured; 4, after culturing for a certain period of time, putting eogammarus possjeticus into the net cage and uniformly spreading the eogammarus possjeticus; 5,transferring the successfully cultured young octopus variabilis into a new breeding pool. Selection of feed and shelters has the advantages that the materials are convenient to take, and the cost islow; meanwhile, a habitat which has sufficient nutrients and energetic feed and is environmentally friendly and close to a natural environment can be provided for culturing the young octopus variabilis, after 30-40 days of raising, the cultured young octopus variabilis can reach the survival rate of 90% or above, and the average body length and the fresh weight can reach 1 cm and 1 g respectively.

Description

technical field [0001] The invention relates to the technical field of aquatic seedling cultivation, in particular to an ecological cultivation method for octopus larvae. Background technique [0002] Long octopus belongs to the phylum Molluscs, Cephalopoda, Dibranchia, Octabrachia, Octopidae, Octopus genus. The local names are Octopus, Horse Octopus, and Octopus. It has the characteristics of delicious meat and rich nutrition, and is exported in large quantities. South Korea, Japan and other countries have high economic value and have become important economic types in the northern seas of my country. In recent years, as prices have risen and fishing efforts have increased, the amount of octopus resources in the Yellow and Bohai Sea regions has declined significantly. Seedling cultivation is an important link in resource restoration and needs to be resolved urgently. [0003] At present, there are many deficiencies in the cultivation method of octopus larvae. In terms of s...

Problems solved by technology

However, there are defects in the above several baits. Artemia and crab seedlings are not easy to obtain and the price is relatively high. The residual bait of bivalve molluscs (open shells) is not easy to clean up, and it is easy to damage the water. Cleaning has the disadvantages of complex operation, high cost, waste of manpower and material resources, which limits the above several larvae cultivation methods
