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.

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:
