Their hearts and other vital organs stay at ambient temperature so while they can hunt in deep cold waters they must regularly return to the surface to warm their innards.
Like reptiles and amphibians fish are cold-blooded poikilothermous vertebrates meaning they get their body temperature from the surrounding water.

Temperature also affects metabolism and metabolic processes occur quicker in warmer water. For example when the sun sets at night their bodies are cooler because it is less warm outside. At different heights the temperature of the water resources varies.
The same fish in 60 F water will have a body temperature near. For example lizards and crocodiles stay in water. Birds and mammals are warm blooded.

Therefore cold-blooded animals must depend on more external factors to control their body temperature.
For over 50 years now scientists have known that despite their reputation not all fish are cold-blooded. Although not as warm as mammals and birds the opah circulates heated blood throughout its body giving it a competitive advantage in the cold ocean depths from 150 to 1300 feet below the surface. Cold-blooded people on the other hand regulate their body temperature even when its chilly outside like other warm-blooded animals.
Almost all fish are cold-blooded ectothermic. A fish swimming in 40 F water will have a body temperature very near 40 F.
