Problems solved by technology

Both methods have the following disadvantages: 1. The quality and quantity of the bait are difficult to guarantee; 2. The predators and pathogenic organisms that may be carried by the natural bait can easily cause the fry to become ill; in addition, in plateau areas, because the climate is erratic, the water temperature is low all year round , the large temperature difference between day and night, etc., the bait organisms in the water body are extremely poor, and the harsh environmental conditions are not suitable for artificial cultivation of a large number of bait organisms
It is difficult to succeed in cultivating seedlings by the above methods
[0004] So far, there have been no research reports, patents or inventions related to the method of artificial breeding of black-spotted catfish fry and fingerlings at home and abroad.

Abstract

The invention relates to a method for cultivating glyptosternum maculatum fries and fingerlings through artificial feed. In an indoor cement pool, clean water resources from rivers are utilized, micro water flow is controlled through manpower, manual mixed feed is provided for feeding, and fries hatched from germ cells are cultivated to fingerlings 3cm in length. The rate of survival of the glyptosternum maculatum fries which live for 2-3 days to be fingerlings which are 3cm long is more than 80%.

Description

technical field [0001] The invention relates to a method for cultivating fry and fingerlings of black-spotted catfish by using artificial feed, and belongs to the technical field of breeding fish fry and fingerlings. Background technique [0002] Fry and fingerling cultivation is an important part of fish artificial breeding. At present, most fish can catch plankton in natural water bodies or artificially cultivate plankton as food for the fry stage, a few fish use natural bait for the fry stage, and use artificial compound feed for the seedling stage to cultivate seedlings. Both methods have the following disadvantages: 1. The quality and quantity of the bait are difficult to guarantee; 2. The predators and pathogenic organisms that may be carried by the natural bait can easily cause the fry to become ill; in addition, in plateau areas, because the climate is erratic, the water temperature is low all year round , the large temperature difference between day and night, etc....
