Embodiment 1

[0042] The method for hybrid breeding of lined seahorses and three-spotted seahorses, the steps are as follows:

[0043] 1. Parental selection and prenatal intensive cultivation of the lined hippocampus and the three-spotted hippocampus

[0044](1) Parental selection

[0045] On April 15, 2014, 30 parents of lined seahorses ♀, lined seahorses ♂, three-spotted seahorses ♀ and three-spotted seahorses ♂, lined seahorses ♀ and three-spotted seahorses were randomly selected from the Zhanjiang breeding base The weight of the ♀ parents is between 7 and 9 g, and the weight of the lined hippocampus ♂ and three-spotted hippocampus ♂ is between 8 and 10 g.

[0046] Select healthy lined seahorses and three-spotted seahorses with well-developed gonads as parents, including females and males of lined seahorses, females and males of three-spotted seahorses.

[0047] (2) Prenatal intensive cultivation

[0048] Parents were reared separately in imitation ecological white barrels (about 1m3)...

Embodiment 2

[0069] The influence of embodiment 2 parental selection on crossbreeding

[0070] The present invention has gone through a lot of exploration, research and verification. In the process of hybrid breeding method, from the selection of parents, the cultivation of parents, the control of hybrid conditions, the careful care of pregnant hippocampus, and the acquisition of the final hybrid offspring, every link The operation and condition control have a subtle relationship with the survival rate of the hybrid offspring and the development of the offspring, and have an important impact on the results of hybrid breeding.

[0071] This embodiment takes the control of several objective conditions as an example to present and illustrate the key role of each link in the breeding method.

[0072] 1. Experimental grouping

[0073] (1) Experimental group: Cross-breeding of lined seahorses and three-spotted seahorses was carried out as follows:

[0074] S1. Select healthy, well-developed ...

Abstract

The invention discloses a crossbreeding method of hippocampus kelloggi and hippocampus trimaculatus. The crossbreeding method comprises the following steps that S1, parents of the hippocampus kelloggi and the hippocampus trimaculatus are selected; S2, strengthening breeding is carried out on the parents of the hippocampus kelloggi and the hippocampus trimaculatus in S1; S3, direct cross and reciprocal cross are carried out on the hippocampus parents in S2; S4, meticulous breeding and parent and baby hippocampus management are carried out on the pregnant parents in S3; S5, produced fry in S4 are bred in similar environment according the same breeding mode; S6, weight and survival rate comparison is carried out on the fry at the month ages of one, two and four, and a high-quality crossbreeding hippocampus germplasm strain with the high survival rate and genetic stability is obtained. The survival rate of the crossbred progeny obtained through the method is greatly improved relative to that of self-bred progeny, a foundation can be provided for breeding a hippocampus disease resisting strain, and development of the hippocampus culture industry is promoted.

Description

technical field [0001] The invention belongs to the technical field of fish hybrid breeding. More specifically, it relates to a cross-breeding method of a lined seahorse and a three-spotted seahorse. Background technique [0002] Seahorses, belonging to the class Fish, Sea Dragons, and the genus Hippocampus ( Hippocampus ), is a rare marine Chinese medicinal material, known as "Southern Ginseng" in my country, which has the effects of tonifying kidney and strengthening yang, strengthening the heart to induce labor, stopping bleeding and analgesia, and calming the nerves. Stranded hippocampus ( Hippocampuserectus ) is mainly distributed on the west coast of the Atlantic Ocean, and is a typical tropical and subtropical seahorse population, with strong fecundity, large individuals and fast growth rate. three-spotted seahorse ( Hippocampus trimaculatus ) is mainly distributed in the Indo-Pacific region. It is an important economic species in my country, accounting for 35% ...
