Problems solved by technology

However, both have the disadvantages of low survival rate or short-distance transportation. In fact, it is a misunderstanding to carry out gas-type oxygenation in the transportation of cuttlefish, because the stress caused by oxygenation leads to increased activity frequency and crowding of cuttlefish. And it is more likely to cause fish bodies to rub against each other, scales fall off, and eventually die

Abstract

The invention relates to a transportation method for natural fingerling or artificial breeding fingerling of coilia nasus, belongs to the technical field of fish farming, and aims at solving the problem of providing a method which is matched with the transportation of coilia nasus fingerling. The technical scheme of the invention comprises selection of a transportation season, allocation of a container for containing fingerling, and setting of the salinity of water for transportation. The transportation method is characterized by adding Yangtze River water or original pond water with the salinity of 0.8%-1% without oxygenation, wherein the water level of a water tank accounts for about 3 / 4 of the volume of the container, the fingerling specification is 8-15cm, the fingerling transportation density is about 1.5g / L, the transportation water temperature is 15-22 DEG C, and the transportation time is preferably not more than 24 hours. The transportation method is applicable to the transportation of the coilia nasus fingerling, with the transportation survival rate above 95%, and the method is simple and convenient, and easy to master.

Description

technical field [0001] The invention relates to a transportation technology for the fingerling of the sword anchovy, specifically, a long-distance transportation method for the natural fish finger of the sword anchovy or artificially bred fish, and belongs to the technical field of fish breeding. Background technique [0002] Swordfish ( Coilia nasus ), also known as long-jawed anchovy, commonly known as "saury fish", is a valuable economic fish that enjoys the reputation of one of the "three delicacies of the Yangtze River". In recent years, as the Freshwater Fisheries Research Center of the Chinese Academy of Fishery Sciences and Jiangyin Shengang Sanxian Breeding Co., Ltd. have made breakthroughs in artificial propagation and seed cultivation of swordfish, the farming industry of swordfish is gradually rising. However, because the fish is very "delicate", the stress response is strong, the scales are easy to fall off, and problems such as "death out of water" have caused...
