specific Embodiment 1

[0024] On May 19, 2013, transported 14 individuals that were cultured in cages on the hull of the Yangtze River for about 4 months. During the transportation, the water temperature was 17°C and the anesthetic concentration was 25ppm. The packing time was 10:30 on May 18, 2013, the time of transportation to the destination was 00:45 on May 19, 2013, and the transportation time was 14.25h. The transportation survival rate is 100%.

specific Embodiment 2

[0025] On October 19, 2013, 65 individuals that were cultured in cages on the hull of the Yangtze River for about 12 months were transported. The water temperature during transportation was 16.6°C, and the anesthetic concentration was 25ppm. The packing time was 9:00 in 2013, the time of transportation to the destination was 01:30 on October 21, and the transportation time was 16.5 hours. The transportation survival rate is 100%.

specific Embodiment 3

[0026] On April 19, 2014, transported 30 individuals that were cultured in cages on the hull of the Yangtze River for about 16 months. During the transportation, the water temperature was 17.6°C and the anesthetic concentration was 25ppm. The packing time was 10:00 on April 18, 2014, the time of transportation to the destination was 01:40 on April 19, 2014, and the transportation time was 15.7 hours. 100% transportation survival rate

Abstract

The invention discloses a rhinogobio ventralis parent fish transporting method. The method includes: cultivating individual rhinogobio ventralis parent fish for 15 days, and stopping feeding the parent fish for 2 days before transportation; sleeving two plastic bags together to form a double-layer packing bag; using anesthetic and clear Yangtze River water to prepare packing water at the final concentration of 25ppm; placing the fish into the inner bag filled with the packing water, and allowing the inner bag with the fish to be filled with oxygen; horizontally placing the tied packing bag in an unbroken foam box; placing ice blocks in the foam box and sealing the foam box with tape; controlling the time from packing bag tying to arriving to destination to be within 24 hours; opening the packing bag to place the fish in cultivating water so as to awaken the fish, and sterilizing in the cultivating water with salt to complete the whole transporting process. The method has the advantages stress reaction of the rhinogobio ventralis parent fish during transportation is reduced, fish body damage is avoided, and transportation survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of fishery, and relates to a method for transporting broodstock of albacore gobi. Background technique [0002] Rhinogobioventralis (Sauvageet Dabry), also known as soil mouse, belongs to Cypriniformes, Cyprinidae, Gobioninae, RhinogobioBleeker, distributed in the upper reaches of the Yangtze River In the main stream and large tributaries such as the Yalong River and Wujiang River, it likes to live at the bottom of the river. The albacore is a rare and endemic fish in the Yangtze River, and it is also an important economic fish. In recent years, due to the impact of human activities such as the development of water conservancy and hydropower projects and overfishing, the resources of albacores have dropped significantly. Research on reproductive technology and other aspects has been paid more and more attention. The transportation of live fish is an important link in the artificial domestication and repro...
