Which factors are responsible for the growth of fish?

  • Water level
  • Air temperature
  • Stocking density

Some Physical, Chemical and Biochemical factors like water temperature, pH, alkalinity, hardness, etc are important to fish growth and mortality.

Fishes exhibit a 'determinate' type of growth in short-lived species of warmer regions and an 'indeterminate' type in long-lived species of colder regions. Growth is measured in units of length and weight and is best represented as the specific growth rate.

Here are some largest fish and their length are-

FishAverage Length
Whale shark 41.5 feet
Basking shark 40.3 feet
Hoodwinker sunfish 7.9 feet
Sharptail mola 9.8 feet
Beluga Sturgeon 24 feet
Southern sunfish 11 feet
Ocean sunfish (mola) 10 feet

How do you measure fish growth?

Removing fish from the water, weighing it in, and noting down the weight. The growth rate of fish in freshwater farming systems has to be monitored throughout the season. Any changes in the expected growth rate could indicate feeding problems, poor water quality, or diseases.
