Pond Surface Area Measurement is Important

Surface area is one of the most important pieces of information that a manager needs to appropriately manage a pond. Yet it is surprising how many people estimate or guess a pond's surface area rather than measure it.

Explanations for Some 'Fishy Questions'

As you might expect, a lot of questions regarding fishing are generated during the summer. The following are examples of some of those questions, followed by explanations.

Proper Management Ensures Good Quality Fisheries in Ponds

Successful sport fish management in ponds addresses the physical or structural attributes of a pond, water quality, plant community, fish stocking, fish harvest, monitoring and records.

Rotenone Can Remove Undesirable Fish From a Pond

Humans have been using rotenone for centuries to harvest fish and manipulate fish communities.

Think About Use Before Constructing Ponds

Many landowners are building and stocking new ponds, as well as re-stocking old ponds that dried up, with fish to increase water reserves and provide fisheries for family enjoyment or income. It's good to take time to consider all of the values that ponds have to offer before actually beginning the dirt work.

Pond Managers Can Take Steps to Avoid a Fish Kill

A fish kill caused by dissolved oxygen (DO) depletion can be a catastrophe for pond managers. Fish kills can occur any time the DO demand is greater than the water can supply - but managers can take steps to avoid such an event in their ponds.

A Secchi Disk is Used to Measure Water Clarity

Standardized measurement of water clarity helps monitor changes that can affect production of fish and aquatic plants, and a Secchi disk is a simple, standard tool used to measure clarity.

Hybrid Hype

Hybrid fishes occur naturally and are raised in hatcheries. Many hybrids have lower fertility but seem to exhibit better growth rates and catchability than the parent species.


Three species of bullhead catfishes occur in Oklahoma and Texas: black bullhead, yellow bullhead, and brown bullhead. Bullheads provide many hours to enjoyment to anglers, especially beginning fishermen. However, they compete directly with channel catfish and sometimes cause water turbidity problems.

Parasite Problems

We receive several summertime calls from fishermen asking about fish infested with parasites. Most often, they are concerned about identification of the parasite and the safety of eating parasite infected fish. The most frequently observed parasites are flukes (grubs) in the larval stage, commonly seen on largemouth bass, bluegill, catfish, and other fishes.
