Artificial taming method of pond with wild bagarius yarrelli

Abstract

The invention relates to an artificial taming method of a pond with wild bagarius yarrelli, belonging to the technical field of fish culture. The method comprises the following steps of designing the environment of a fish pond, sterilizing the fish pond, sterilizing before putting the bagarius yarrelli and casting baits for taming eating. The method comprises the following detailed steps of: dividing the fish pond into a plurality of ponds which are provided with water inlets and water outlets and have different volumes, then manufacturing water flow and arranging hidden places and activity places in the pond; pumping water from the pond to be dry before putting the bagarius yarrelli for taming, leading calcium lime to form pulp, splashing the pulp in the whole pond according to 10 to 300kg per mu and sterilizing; before putting the bagarius yarrelli, using antibiotic solution of 10 to 100IU / L for soaking each bagarius yarrelli for 15 to 30 minutes for sterilization; before putting the bagarius yarrelli for taming, putting living shrimps, living little fishes and conches in the pond by 10 to 30kg per mu, after putting the bagarius yarrelli for 30 days, putting fish meat of 1 to 3kg on a food table every day, and leading the bagarius yarrelli to be capable of intaking food gradually at fixed time and place. The artificial taming method has simple and convenient operation, low cost and high survival rate of bagarius yarrelli, realizes artificial taming of the wild bagarius yarrelli in the pond and lays the foundation for developing and utilizing native fish resource, namely bagarius yarrelli.

Description

Technical field:

[0001] The invention relates to a pond artificial domestication method for wild giant chilblains, belonging to the technical field of fish breeding. Background technique:

[0002] Bagarius yarrelli (Sykes)] belongs to Siluriformes, Scorpidae, and the genus Bagarius. Because of its yellow flesh, it is also called yellow croaker and squid. Distributed in the Lancang River, Nujiang River and Yuanjiang River system. In China, it is a unique large-scale fish that is only distributed in Yunnan, and its weight can exceed 50kg. It is the main food fish in the place of production.

[0003] Due to drastic changes in the ecological environment, especially the construction of hydropower stations on the main streams of the Lancang River, Yuanjiang River, and Nujiang River, where the giant chinchillas are native, the migration channels of fish have been blocked, and the resources of wild giant chilblains have become less and less. In order to protect and develop the rar...

Embodiment Construction

[0012] The method of the present invention includes the steps of fish pond environment design, fish pond disinfection, disinfection before feeding giant chilblains, and baiting and taming; wherein:

[0013] (1) Fish pond environment design: divide the fish pond into 5 ponds with inlet and outlet ports and different volumes, so that the fish pond can naturally enter and drain when there is external water source, and create flowing water by pumping and circulating between fish ponds when there is no external water source; Build a hidden place by the pool; plant water hyacinth in the corner of the pool as a shade place; pile some smooth stones in the corner of the fish pond as a place for giant chivalry activities;

[0014] (2) Disinfection of fish ponds: Before the fish ponds are put into the domesticated giant chinchillas, the water in the ponds is first drained, and 10--300kg of quicklime (CaO) is used per mu to form a slurry and the whole pond is sprayed for disinfection, and ...
