In summer due to high temperatures, fish will avoid the summer heat; therefore, night is the best time for fishing.
Moreover, other cytotoxic and carcinogenic products of omega-3 PUFA may be formed in fish after cooking them at extremely high temperature (by broiling/frying fish) or preserving them by smoking procedures [ 26].
Accordingly, after start-feeding fish from the high intensive temperature regime displayed a higher SGR than the low temperature fish, 2.82 and 1.96 respectively.
While, Hsp90 and Hsp110, besides Hsp70, are required for immediate survival of fish at high temperature, Hsp60, Hsp70 and Hsp78 are needed for long term survival at high temperature in Channa.
Fish exposed to high temperature (high intensive regime) had a significant higher incidence of deformities than fish from the same origin reared under a conservative temperature regime (low intensive regime).
From the heat stress experiment, we pooled RNA from six fish from the control group and six fish from the high temperature group for construction of two suppressive subtractive hybridization (SSH) cDNA libraries.
The hsp60 transcript is up regulated in response to high temperature treatment in different organisms including fish [ 19, 31, 32].
Fish exposed to the high temperature regime showed a markedly higher growth rate and a significant higher percentage of deformities in the spinal column than fish reared at low temperatures.
How the hsp expressions are modulated if the fish is exposed to high temperature for longer periods?
High temperature also hastens diffusion.
