Ecological breeding method of giant salamanders

Abstract

The invention discloses an ecological breeding method of giant salamanders. The ecological breeding method comprises step 1, pond building which comprises building a plurality of breeding ponds in a natural cave; step 2, seedling throw which comprises selecting healthy disease-free seedlings which are bred artificially and throwing the seedlings into the small ponds or the large ponds according to the size and the strength of the seedlings, wherein 15 to 20 seedlings are thrown into every pond; step 3, bait feeding which comprises directly throwing fresh baits into the pond water according to the 10 to 15% of the total weight of the giant salamanders and performing the attachment breeding of small trash fishes, loaches, cold water shrimps and crabs ; step 4, daily management which comprises controlling the water level, maintaining the water temperature to be 16 to 20 DEG C and a ph (potential of hydrogen) value of the pond water to be 7.0 to 7.5, performing regular disinfection on a water body through bleach or chlorine dioxide and mixing the allicin, gallnut or rhubarb powder into the baits to perform once feeding every 15 days. According to the ecological breeding method of the giant salamanders, the constant breeding temperature of the natural cave and the weak base water quality formed by the Karst landform cave are beneficial to the growth and reproduction of the giant salamanders and accordingly the life of the giant salamanders is long, the nature of the giant salamanders does not degrade, the incidence of diseases is reduced, and the growth and reproduction rate and the survival rate are improved.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to an ecological breeding method for giant salamanders. Background technique [0002] Giant salamanders are commonly known as "salamanders". At present, there are two methods of breeding giant salamanders. One is to use natural streams to stock them, that is, to build dams in the downstream of the stream and to stock them naturally in the upper reaches. Once a giant salamander gets sick in this method, it will affect a large number of giant salamanders and cause a large number of giant salamanders to die. Moreover, the mating of the species of fish is carried out out of order, and the same species will be killed during the estrus period, which will cause the species of fish to be disabled. Therefore, the survival rate of the breeding is very low; The weak point is that the life-span of the species of fish is short, and it will degenerate within 2 to 3 years and consume a lot; in t...

Therefore, the survival rate of the breeding is very low; The weak point is that the life span of the species of fish is short, and it will degenerate within 2 to 3 years, and consume a lot; the method of cultivating giant salamanders in naturally formed karst caves has not been disclosed in the current prior art
