How many trout die a year?

The exact number of trout that die each year is difficult to determine as there are many factors that can affect trout mortality, including: natural causes, such as predation, disease, and old age; and human-caused factors, such as habitat destruction, water pollution, and overfishing.

However, some estimates suggest that up to 50% of wild trout die each year, while hatchery-raised trout may have a mortality rate of up to 30%. This means that millions of trout could be dying each year.

Trout populations are constantly changing and subject to environmental influences, so a definitive figure is challenging to provide.

It is essential to take note of this issue to prevent the species from depletion.
