Problems solved by technology

[0003] This invention solves the traditional breeding method of self-propagation and self-cultivation of sea cucumbers at present, and cannot produce new sea cucumbers with the advantages of plum blossom ginseng in the southern sea area and sea cucumber in the northern sea area. In order to solve the problem of sea cucumber species, we invented a method of cross-breeding new species of sea cucumbers by using plum blossom ginseng from the southern sea area as the male parent and sea cucumber from the northern sea area as the female parent.

Embodiment Construction

[0019] 1. Seed selection

[0020] Plum ginseng species were collected from the sea area of ​​Hainan Island, and sea cucumber species were collected from the sea area of ​​Qingdao, Shandong;

[0021] 2. Adjust the water temperature

[0022] The plum ginseng species collected from the waters of Hainan Island must first control the water temperature, adjust the water temperature at 15°C-17°C, and store it for about 50 days; the sea cucumber species collected from the Yellow Sea of ​​Qingdao, the water temperature is low, adjust the water temperature to synchronize with the water temperature of the plum ginseng species , the fluctuation of PH value is less than 0.5, after intensive cultivation for a period of time, increase the water temperature by 0.5°C every day until the water temperature reaches 20°C;

[0023] 3. Matching group into the pool

[0024] When the gonads of Prunus japonicus and A. japonicus are mature, male P. japonicus and female A. japonicus are selected and pu...

Abstract

The invention discloses a method for hybridization of a south thelenota ananas and a north stichopus japonicus. The method is characterized by comprising the steps of seed sorting, water temperature adjustment, group pouring in a pool, incubation and management after the incubation. The method solves the problem that the conventional breeding method for self-breeding of sea cucumbers cannot produce novel sea cucumber varieties with the advantages of the south thelenota ananas and the north stichopus japonicus, and is suitable for breeding the sea cucumbers in each sea area and coastal areas.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for breeding a new species of sea cucumber by hybridizing the southern plum-blossom sea cucumber and the northern spiny sea cucumber. Background technique [0002] At present, my country's sea cucumbers are divided into two types: plum-blossom ginseng in the southern sea area and sea cucumber in the northern sea area. Ginseng has high nutritional value and strong disease resistance, but is small in size and low in yield. In breeding, they all adopt the traditional method of mating male and female sea cucumbers of the same species and self-propagating, that is, plum ginseng only breeds plum blossoms Sea cucumbers, sea cucumbers only breed sea cucumbers, and cannot produce new species of sea cucumbers that have the advantages of plum-flowered ginseng and sea cucumbers. Contents of the invention [0003] In order to solve the problem that the current traditional breeding meth...
