Embodiment 1

[0021] The method for supplying the open bait of the black-spotted catfish comprises the following steps:

[0022] On the 10th day after film emergence, the larvae start to float up and feed the hatched Artemia; feed them at any time to ensure that there are Artemia in the parallel tank at any time;

[0023] From 20 days after the film is released, the rainbow trout is fed with open powder;

[0024] From 35 days after filming, feed the chopped red nematodes;

[0025] From 60 days after filming, the rainbow trout feed, pig liver and red nematodes are mixed, kneaded into balls and fed, and fed to the places where the seedlings are focused.

Embodiment 2

[0027] This embodiment is on the basis of embodiment 1:

[0028] The mixing ratio of the rainbow trout feed, pig liver and red nematode is 2:1:1.

Embodiment 3

[0030] This embodiment is on the basis of embodiment 1:

[0031] The mixing ratio of the rainbow trout feed, pig liver and red nematode is 2:1:1.

[0032] The rainbow trout open powder is fed once every two hours, 6 times a day, and the residual bait is cleaned after 1 hour of feeding.

Abstract

The invention provides a method for supplying glyptosternon maculatum initial feed. The method comprises the following steps: feeding hatched fairy shrimps after fry is hatched for 10 days and startsto come up; starting to feed rainbow trout initial feed after the fry is hatched for 20 days; starting to feed chopped tubificidae after the fry is hatched for 35 days; and starting to feed balls of mixture of rainbow trout initial feed, pig liver and tubificidae in the place with fries gathered after the fry is hatched for 60 days. The method can be used for successfully solving the problem of initial feed of glyptosternon maculatum fries, and the survival rate of fries can be remarkably increased.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for supplying open-mouth bait for the black-spotted catfish. Background technique [0002] Glyptosternum maculatum (Glyptosternum maculatum) is only distributed in the Yarlung Zangbo River system in China. It belongs to Siluriformes (Siluriformes), Sisoridae (Sisoridae), and Glyptosternum (Glyptosternum). It is the only one of the three known species of Glyptosternum. The species distributed in China occupies an important position in the research on the phylogeny of the fishes in China. Black-spotted catfish has delicious taste, delicate meat, and good taste. It can also be used as medicine in Tibetan medicine. It has both edible and medicinal value, and its selling price is increasing year by year. The current market price can reach 1700-2600 yuan / Kg, and its economic value is relatively considerable. . In recent years, due to the impact of human activities on it...
