Problems solved by technology

However, due to the specific living habits of the albacore, there are technical difficulties in the process of artificial domestication, such as strong stress and difficult domestication, resulting in a low domestication survival rate of the albacore, which largely limits the Research on Conservation Techniques of Finnis
[0004] At present, there are few reports on domestic and foreign studies on the domestication of albacores. Therefore, it is urgent to find out a method of domesticating wild albacores to induce them to eat compound feed in an artificial environment and improve the quality of albacores. The domestication survival rate of gudgeon lays the foundation for a breakthrough in its large-scale broodstock breeding technology

Embodiment 1

[0029] A safe method for long-distance transport of wild albacores. The method steps include a starvation stage, an artificial induction stage, and a complete feed compound feed stage.

[0030] (1) Starvation processing stage

[0031] After the wild albacore was transported to the breeding site, it was soaked and disinfected with 1ppm methylene blue + 0.3% salt for 2 hours, then temporarily raised in a 3m-diameter breeding pond, and starved for 7 days. During the temporary breeding period, the flow rate of the culture pond was kept at 0.3m / s, the bottom of the culture pond was laid with pebbles, and the sunshade net was used for half-shading treatment above the culture pond.

[0032] (2) Artificial feeding stage

[0033] The stage of artificial baiting includes two stages, one is the stage of fully feeding biological bait, and the other is the stage of artificial bait and compound feed.

[0034] After 7 days of starvation treatment for wild albacorer, start feeding marine mo...

Abstract

The invention belongs to the technical field of rare and peculiar fish farming and particularly relates to a feed training method of wild rhinogobio ventralis. The feed training method includes a hanger phase, an artificial inducing phase and a complete mixed-feed feeding phase; the artificial inducing phase includes two stages, one is a complete live-food feeding stage, and the other is an artificial mixed-feed inducing stage. With the method, the technical problem of difficult feed training of the wild rhinogobio ventralis under the condition of artificial breeding is successfully solved, the technical base of large-scale cultivation of parent fish of the rhinogobio ventralis is established, and large-scale propagation and large-scale releasing of the rhinogobio ventralis are made possible.

Description

technical field [0001] The invention belongs to the technical field of rare and unique fish culture, and in particular relates to a method for taming wild albacore. Background technique [0002] Rhinogobio ventralis (Rhinogobio ventralis), which belongs to Cyprinidae and Cyprinidae, is a small bottom-dwelling economic fish endemic to the upper reaches of the Yangtze River. According to statistics from the Institute of Hydrobiology of the Chinese Academy of Sciences since 1997, the longfin catfish accounts for 10% of the upstream fishery resources. The wild resources of the scorpion are in sharp decline. [0003] In recent years, relevant domestic aquatic research institutes have strengthened the research on the domestication, breeding and artificial reproduction of the albacore, trying to realize the ex situ protection of the species by establishing an artificial population, in order to restore the natural population of the albacore resource. However, due to the specific ...
