Factory breeding method for Octopus variabilis

Abstract

The invention discloses a factory breeding method for Octopus variabilis. According to the method, females of Octopus are removed from a polyculture pond after parents of Octopus mate, thus mutual injuring of males and females of Octopus is prevented and the quantity of fertilized eggs is guaranteed; the females of Octopus and the fertilized eggs are separately cultured, thus the effect of the parents of Octopus upon the water environment is less and hatching rate influenced by frightening is avoided for the parents of Octopus. In addition, the young Octopus is traditionally considered to be fed only with opossum shrimps, adult Artemia, Monocorophium acherusicum and the like as initial feed, while, through long-term observations and experiments, the inventor finds that the young Octopus can also be initially fed with miscellaneous juvenile crabs lower than 0.1g in weight, and accordingly survival rate of the young Octopus can be increased. Therefore, the method having the advantages is especially suitable for popularization and application to the field and has very promising market prospect.

Description

technical field [0001] The invention relates to a breeding method of aquatic products, in particular to a factory breeding method of long octopuses. Background technique [0002] Long octopus is also commonly known as octopus and octopus. Its meat is delicious and can be eaten fresh or dried into dried octopus. It has high edible value, and long octopus can also be used as medicine. It is a tonic for postpartum women to replenish deficiency, produce milk, and promote lactation. At the same time, long octopuses and other small octopuses are also one of the baits for fisheries. Just because the long octopus has the above-mentioned economic value, the long octopus has also been bred in the field of artificial breeding of aquatic products, but because the long octopus has the habit of killing each other after mating, the egg production will be affected; at the same time, the long octopus The hatching mainly adopts the method of female octopus protecting eggs. Although this meth...

Problems solved by technology

Just because the long octopus has the above-mentioned economic value, the long octopus has also been bred in the field of artificial breeding of aquatic products, but because the long octopus has the habit of killing each other after mating, the egg production will be affected; at the same time, the long octopus The hatching mainly adopts the method of female octopus protecting eggs. Although this method can ensure a high hatching rate, the overall time is relatively long, and in the process of hatching, the female octopus will affect the hatching due to factors such as fright and light.
