What is a Fish Kill?

Fish kills are an unfortunate reality for ponds and lakes. Most fish kills are prompted by a change in the seasons, but some can be attributed to human related factors such as the improper use of chemical herbicides/pesticides or polluted runoff. No matter the cause, experiencing a fish kill can be very traumatic.

When Does Fish Kill Happen?

We typically see the most major fish kills during two distinct times of the year, winter and late summer. Different factors play a role in each of these, but ultimately most fish kills are a result of low dissolved oxygen levels causing the fish to suffocate.

Why does Fish Kill Happen?

Ponds and lakes with an abundance of excess nutrients and organic sludge build up (Eutrophic) are most susceptible to fish kills. These waterbodies have a much higher latent oxygen demand so oxygen levels can drop very quickly if something goes wrong. Shallow ponds and lakes also tend to have more trouble with fish kills. These waterbodies hold less water, so there isn’t as a lot of volume for oxygen storage.
