specific Embodiment approach 1

[0013] Specific embodiment one: the artificial domestication method of a kind of wild broodstock of the black spot catfish of the present embodiment, the concrete steps of described method are as follows:

[0014] Step 1: Select the wild broodstock of the wild black-spotted catfish; select the high-quality wild black-spotted catfish broodstock with a body weight of more than 40g, a body length of more than 14cm, no injuries on the body surface, and good health and vitality;

[0015] Step 2: Prepare the domestication pond; the water quality requirement of the domestication pond is mountain stream water or groundwater, the water temperature is 12-14°C (the domestication temperature of the broodstock), the pH is 7.2-7.5, the dissolved oxygen is kept > 6mg / L, and the running water is raised , the flow rate is 50-80L / min;

[0016] Step 3: domesticating the broodstock;

[0017] 3.1, feeding stage of pulpy bait; adopt artificial oral feeding method to feed the broodstock of pulpy ba...

Abstract

The invention discloses an artificial domestication method of glyptosternum maculatum wild parent fish, and belongs to the technical field of aquaculture. The artificial domestication method comprisesthe steps of selecting wild glyptosternum maculatum parent fish; preparing a domestication pond; carrying out domestication of the parent fish; performing a paste bait feeding stage; feeding the parent fish with the paste bait by adopting an artificial oral feeding method on the day of fishing and transportation, and placing the parent fish in the domestication pond after transportation; performing a paste bait and live loach feeding stage; adopting live loaches to gradually replace paste baits for feeding, wherein the replacement method comprises the steps of carrying out feeding by the paste baits and the live loaches for 4-5 days according to the frequency ratio of 2 to 1 every day, and conducting feeding for three times every day; afterwards, carrying out feeding by the paste baits and the live loaches for 4-5 days according to the frequency ratio of 1 to 2 every day, and conducting feeding for three times every day; next, carrying out feeding with only the live loaches for 4-5 days, and conducting feeding for three times every day; executing a live loach feeding stage; after the feeding stage of the paste bait and the live loaches, continuously feeding by the live loaches; and conducting feeding twice a day. The method is used for artificial domestication of the glyptosternum maculatum wild parent fish.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial domestication method for wild broodstock of the black-spotted catfish. Background technique [0002] Glyptosternum maculatum (Glyptosternum maculatum) belongs to the family Glyptidae and the genus Glyptosteus, commonly known as Bakri and Lhasa catfish. It is a unique fish in the middle and upper reaches of the Brahmaputra River, and has a unique biological evolution mechanism to adapt to plateau waters. The black-spotted catfish has tender meat, delicious taste, few intermuscular thorns, and has certain medicinal value, so it is deeply loved and respected by the people in Tibetan areas. At present, the selling price in the Lhasa market has reached as high as 1700-2600 yuan / kg. In recent years, due to the impact of overfishing, water conservancy projects, environmental pollution and habitat changes, the population resources of the black-spotted catfi...
