Interpreting Your Catch – Using Your Catch Records to Measure the Health and Growth of Your Fishery

Presented by:

Dr. Todd Sink

Aquaculture Extension Specialist, Texas A&M AgriLife Extension Service

Director, TAMU Aquatic Diagnostics Laboratory

Description:

If you have attended previous webinars such as the fish management strategies webinar in April, you should understand the importance of keeping catch and harvest records for your pond.

Not only to these document fish harvest to ensure management goals, they can also be used to determine numerous facets of your fishery and its health. The best part is, if you consistently maintain catch/harvest/and perhaps seine or cast net records for several years in a row, you can document the health and growth of your fishery over time at no cost to you just as well as paying for expensive electrofishing.

Join us as we use real pond fishery datasets and simple online tools to calculate catch per unit effort, relative abundance, proportional stock density, relative stock density, relative weight, species composition, size distribution, and age class, and how to use relative weight tables to assess your fish growth.

At this point in the year, you should have enough data from catch records to be able to accurately assess the health of your fishery using these techniques.

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