Embodiment Construction

[0032] Describe technical method of the present invention in detail below by embodiment:

[0033] Such as figure 1 , (1) Long-distance transport of long-finned gobi

[0034] From May 2013 to December 2013, 1208 wild albacores were collected in Yibin River Section, Sichuan Province. Wild albacores are transported in live fish transport boxes, which are made of high-density polyethylene and have a volume of 200-400L. During transportation, add 50mg / L of MS-222 and 5~10ppm of plant polysaccharides (Liyang "activated") and 10~20ppm of compound Chinese herbal medicines (gentian, plantago, Bupleurum, angelica, gardenia , motherwort, licorice, rhubarb, salvia miltiorrhiza, white peony root, ganoderma and other mixed medicines), after the medicines are added, mix and stir evenly before loading into fish and transporting, the transportation density is 20-25kg / m 3 , Continuous oxygenation with pure oxygen throughout the transportation process, with a transportation survival rate of ...

Abstract

The invention relates to a rhinogobio ventralis manual propagation technology which specifically includes four steps of domesticating, strengthening propagation, parent fish spawning induction, fertilization incubation and the like. The method breaks through the rhinogobio ventralis manual propagation technology for the first time at home and abroad, successfully solves the technical difficulties of high stress, difficult domesticating and streak gonads in the rhinogobio ventralis domesticating propagation process, and successfully achieves rhinogobio ventralis manual propagation for the first time. In the period from June 27th to May 9th in 2014, spawning induction of rhinogobio ventralis is conducted successfully for five times, about 97 thousand fertilized eggs are obtained, the fertility rate reaches 98.9%, about 30.5 thousand new-born fish fries are obtained, and stock enhancement of the rhinogobio ventralis becomes possible. The method achieves the technical reference and demonstration effects on protection of valuable rare fishes in the upstream of the Yangtze River and has great economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the field of protection of rare and unique fishes in the upper reaches of the Yangtze River, and in particular relates to the artificial propagation technology of the albacore gizzard. Background technique [0002] Longfin snout ( Rhinogobio ventralis ), commonly known as soil consumption, belongs to Cyprinidae and Subfamily Cyprinidae. It is mainly distributed in the main and tributary waters of the Jinsha River. It lives at the bottom of the water body. It is afraid of light and disturbed. In recent years, due to water pollution and the impact of human activities, the resources of albacores have declined sharply. Taking the Yibin River Section as an example, the annual catch of albacores accounted for 12.42% of the total annual catch in 1998, while By 2002, the annual catch of albacore was only 2.26% of the total annual catch. [0003] At present, the research on the albacorer mainly focuses on biology, population ecology, ...
