Abstract
Global warming is a universal issue and it
attain a great attention in the aquatic ecosystem and aquaculture suntist. The
present study investigates the impact of temperature on the growth and
development of two freshwater fishes Labeo rohita and Oreochromis
niloticus exposed with three different temperature regimes viz., 30, 33 and
36°C. During the experimental period highest feed conversion ratio (FCR) and
highest specific growth rate was recorded at 33OC. Highest survival
rate of L.rohita & Oreochromis niloticus was (90.00±00)
observed at 30OC and 33°C whereas the lowest survival rate (70.00±00)
was recorded as Labeo rohita and Oreochromis niloticus. Highest
percentage of Dissolved Oxygen (DO) recorded in 6.37±0.16 mg/ L on 10th
and 30th days after treatment at 30oC but no significant
variation of pH level among all the experimental temperature. Altogether, this
study confirmed that both fresh water fishes have attained an optimum growth at
33°C, whereas high survival risk for L.rohita and O.niloticus
were recorded at 36oC.
