Problems solved by technology

[0006] In order to solve the above problems, the present invention provides the cultivation method that uses jellyfish as material, utilizes the autolysis characteristics of jellyfish to induce jellyfish autolysis, and jellyfish autolysis releases easily absorbed nutrients such as polypeptides, which solves the problem of eel early larvae (generally It is the problem that the larvae from the hatching of fertilized eggs in 3-5 days to 1-19 days after emergence of the membrane) do not have the ability to digest and cannot feed the early larvae of eels

Embodiment Construction

[0017] The following embodiments are only used to illustrate the present invention, and the scope of protection of the present invention is not limited only to the following examples. Those of ordinary skill in the technical field can realize the purpose of the present invention according to the disclosure content of the present invention.

[0018] Use artificially cultivated or wild live jellyfish and early eel larvae (larvae hatched from fertilized eggs for 3 to 5 days, and the yolk sac is close to disappearing).

[0019] Tools: gloves, scissors, plastic bags or fresh-keeping bags, and other materials needed to cultivate eel seedlings (oxygen pumps, artificial seawater, water tanks for seedlings, etc.).

[0020] Cultivation method: (1) Remove the poisonous barbed wire of jellyfish. Jellyfish have spines that grow on the edge of the umbrella-shaped head, which can sting juvenile eels, so they must be removed. Wear gloves and use scissors to cut off all the thorns. To ensure...

Abstract

Disclosed are an initial feed for early-stage larvas of eels and a culturing method using the feed. The feed comprises marine organisms having an autolysis characteristic such as jellyfishes.

Description

technical field [0001] The invention belongs to the field of fish seedling cultivation, in particular to an opening bait for early eel larvae and a cultivation method using the bait. Background technique [0002] The scientific name of eel is eel, and its nutritional value is very high, so it is called soft gold in water. The growth process of the eel is very peculiar. It first lays eggs in sea water and grows into seedlings, and then enters fresh water to grow. At present, the Japanese eel cultured in China, Japan and South Korea all rely on wild seedlings. Due to overfishing, eel seedling resources are declining year by year. Moreover, due to many problems in cultivation technology, the yield of wild seedlings caught is low, which also causes further waste of resources. The research on the artificial reproduction of eels has always been a difficult problem in the international aquatic biology community, so it is called the Goldbach conjecture in biology. . [0003] The...
