An effective method to improve the domestication survival rate of wild copperfish and albacores

Abstract

The invention discloses a transportation and quarantine method for improving domesticating survival rate of wild coreius guichenoti and rhinogobio ventralis. The method includes steps of 1), quarantine of country of origin: immersing in methylene blue and antibiotic to quarantine; exchange water and drug every day; 2), long-distance transportation: adding antibiotic and MS-222 to the transportation water; 3), domesticating quarantine: the quarantine drug is the same as that in the country of origin in early phase. Feeding biological bait to domesticate; evenly mixing artemisinin and naphthoquine phosphate in a paste in later period; 4), daily management: observing a fish body every day and observing main indexes of the water quality; 5), disease prevention and treatment: target to preventand treat body surface wound, phytosis, saprolegniasis, Ichthyophthiriasi and teniasis. The method is easy to carry out and simple in operation; the survival rate during the long-term transportation and quarantine period is effectively improved by over 90%; meanwhile, the method lays a foundation for the successful domestication in the next stage, thus the manual breeding work of the wild coreiusguichenoti and rhinogobio ventralis is smoothly carried out.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an effective method for improving the domestication survival rate of wild copperfish and albacore, including the whole process from the quarantine of the capture place to the quarantine of the transportation and the domestication place, especially related to the quarantine process during the quarantine process. The recovery of wounds of copperfish and albacore, as well as the prevention and control of diseases such as bacteria, mold, melonworms and tapeworms, are suitable for the artificial reproduction of copperfish and longfin. Background technique [0002] Both the round-mouthed copperfish (Coreiusguichenoti) and the long-finned snout (Rhinogobioventralis) belong to Cypriniformes (Cypriniformes), Cyprinidae (Cyprinidae), Gotiongiae (Gotiongiae), and are endemic fish in the upper reaches of the Yangtze River and its tributaries. As a fish that lays floating eggs, its enti...

Problems solved by technology

Although this method can improve the survival rate of wild copperfish, it does not specifically solve the following problems in the quarantine, transportation and domestication of copperfish: 1. The stress response is intense, and it is not suitable for artificial injection and irritating chemicals. Treatment such as soaking or smearing of drugs; ② wound fungal infection; ③ parasitism of small melon worms; ④ parasitism of intestinal tapeworms

In addition, there are few reports on improving the domestication survival rate of albacores from the perspective of quarantine methods
