Apart from any fair dealing for the purpose of private study or research, no Industrialisation effects streams where the species lives. In these habitats, the animal mostly lives in dark muddy or rocky crevices along the banks. The water temperature also plays apart in the species feeding, with many stopping feeding when water temperatures rise above 20 °C and if the water temp reaches 28 °C feeding will entirely stop for all animals while 35 °C is lethal. The method comprises main steps as follows: temperature regulation, light regulation, water regulation, bait feeding, sperm culture solution preparing and fertilized egg hatching.

Most Chinese giant salamanders stop feeding at water temperatures above 20 °C (68 °F) and feeding ceases almost entirely at 28 °C (82 °F). In order to demonstrate this, the authors studied two conditions: (1) salamanders raised in warmer temperatures would grow faster and have more energy than those raised in cooler temperatures; and (2) salamanders raised in warmer water temperatures and fed at will would be heavier and have more energy than wild giant salamanders. The present invention discloses a method of breeding giant salamander in tunnels. Chinese Giant Salamanders (Andrias davidianus) have experienced an 80% population decline since the 1950s.
