Liming & Clearing Ponds Webinar

August 20 @ 6:00 PM - 7:30 PM


Presented by Dr. Todd Sink
Aquaculture Extension Specialist,
Texas A&M AgriLife Extension Service Director,
TAMU Aquatic Diagnostics Laboratory

This 1-hour how-to educational program will cover water quality aspects related to the need to lime ponds and potentially clear them.

Most people are surprised to learn how critical water quality is for their fish, how many different water quality factors can impact their fish (often in unusual ways), and how minor amendments to water quality including liming or clearing their pond can drastically improve their fishery.

Alkalinity, hardness, and calcium all affect fish survival and growth, and yet alkalinity is naturally decreased over time in a pond as photosynthesis and bacterial processes occur in a pond. This can lead to reduced primary productivity (food and energy production) and in turn lead to reduced fish growth and smaller fish populations. In rare cases, it can even lead to fish deaths and collapse of recruitment to a fishery.

The primary way in which to increase alkalinity, hardness, and calcium is through liming a pond. We will discuss the various compounds that can be used to lime a pond and what effect it will have on your fishery. In addition, turbidity (muddy water) also drastically limits primary productivity and fish growth and can be aesthetically displeasing to look at.

We will discuss the various compounds that can be used to clear a pond, when to use them, and how to conduct a clearing test or commission a lab to do one for you. We will also cover what is tested during a standard water quality test, how to fix any issues found during the test, how to apply treatments, and how to have your water quality tested.

There will be a 30-minute Q&A session at the conclusion of the webinar.
