Embodiment

[0021] On April 20, 2008, the newly born young hippocampus were divided into 6 groups (groups A, B, C, D, E, F and G), of which groups A, B and C were experimental control groups, and groups E and F and group G as the experimental group. The number of juvenile seahorses in each group is 40, and the size of the breeding tank is the same (length×width×height: 80×40×50 cm); the salinity, pH value and dissolved oxygen of the breeding water are 33±1.0‰, 7.7±0.4 respectively and 6.5±0.5 mg / l, slightly aerated to ensure that no air bubbles occur.

[0022] control group

[0023] From April 20 to June 19, 2008 (60 days), young seahorses in groups A, B, and C were fed with freshly hatched Artemia (0.21±0.023 cm) every day for 1-30 days. Feed 6 times, and feed with enough food; the feces are siphoned clean every day. Within 30-60 days, Artemia (0.93±0.275 cm) and frozen mysis Mysis spp (body length 0.72±0.14 cm) were fortified with flat algae and chlorella for 15 days in the hippocamp...

Abstract

The invention discloses a method for inducing body color change of young hippocampuserectus. In the method, the 20-day-old young hippocampuserectus is induced under physical environmental factors, so that the body color of the young hippocampuserectus is changed from black to yellow or saffron yellow, the color can be kept for a long term, and the survival rate of the young hippocampuserectus canalso be remarkably improved. The body color of the young hippocampuserectus is subjected to induced change by using the method disclosed by the invention, thus the market value of the living hippocampuserectus can be increased, and the commercial culture efficiency of the hippocampuserectus is favorably improved.

Description

technical field [0001] The invention relates to the technical field of hippocampus breeding, in particular to a method for inducing the color change of the larva striated hippocampus. Background technique [0002] At present, there is no patent report on changing the body color of seahorses in the world; based on the biological characteristics of seahorses, using scientific methods to change the body color of seahorses from black to yellow or orange, the price of single-tailed seahorses in the world will be reduced. Improve by 3~5 times. But unfortunately, most of the research is still on the effects of factors such as breeding environment, bait selection and breeding management on the reproductive efficiency and survival rate of the lined seahorse, while the comprehensive effect of environmental factors and behavioral ecology that affect the change of hippocampus body color Studies have reported little. Contents of the invention [0003] The purpose of the present inven...
