Tips on ponds’ upkeep offered


The time has come to get back into the rhythm of active pond management, said Scott Jones, small impoundmen­t extension specialist at the University of Arkansas at Pine Bluff.

While ambitious pond owners monitor and manage their ponds all year long, most casual owners get back into the game in the spring and into the fall.

“As with lawn care and landscapin­g, pond management can be as complicate­d — and as expensive — as you want to make it,” he said. “But a few simple spring adjustment­s can help the pond and its fish start the year strong.”

Most fish species begin spawning in the spring, when a pond’s water temperatur­e is about 60 to 70 degrees, Jones said. Some species such as bluegill will spawn several times during the summer.

“Spawning is an energy-demanding process, so you want your fish well fed before and after for better success and survival,” he said.

Jones offers pond owners the following feeding tips:

■ Begin feeding fish when the water is above 65 degrees. Continue feeding throughout the summer until the water cools to about 65 degrees in the fall or when fish stop responding to the feed.

■ Bluegill grow exceptiona­lly well when given a floating feed. Catfish, minnows and even grass carp will readily eat fish feed.

■ Budget-friendly feeds with 28% to 32% protein are acceptable. But remember that fish grow faster on feeds with 36% to 40% protein, which are more expensive.

■ Provide as much feed as fish will eat in five to 10 minutes, one or two times a day, up to about 15 pounds per acre per day.

■ If feeding once a day, then feed fish about an hour before sunset.

“Abundant bluegill population­s are usually enough to feed largemouth bass adequately in ponds,” Jones said. “However, supplement­al stocking of fathead minnows, golden shiners or even goldfish at 5 to 10 pounds per acre or more in the spring will give your bass a boost of nutrition. This will help them bulk up before the spawn and

recover more quickly from the process.”


If a pond has a history of aquatic weeds, then the weeds have likely already started growing even though they may not be visible, Jones said. Many aquatic weeds begin growing when the water temperatur­e is in the upper 50s to low 60s.

These weeds are most vulnerable to herbicides when they are small and rapidly growing, he said.

Treatment options become progressiv­ely less effective as the plants get larger and store more energy.

“The best time to start herbicide applicatio­ns is when the water reaches the mid-60s to low 70s,” Jones said. “Be sure to identify weeds correctly before treatment because no single aquatic herbicide is 100% effective on all plant species. University of Arkansas Cooperativ­e Extension Service county agents, Arkansas Game and Fish Commission fisheries biologists and UAPB aquacultur­e and fisheries specialist­s can help you identify your plants and select effective, safe chemicals.”


Fertilizat­ion programs should begin when the water reaches about 65 degrees and should continue until the water drops below about 60 degrees in the fall. Each pond will react differentl­y to fertilizer­s, so farm pond owners will need to adjust their applicatio­ns based on how the ponds behave.

“You should only begin a fertilizat­ion program if your water alkalinity and hardness are above 20 ppm (mg/L); your water is not consistent­ly muddy; you intend to observe, maintain and manage the resulting plankton bloom throughout the year; and you are willing to harvest more fish,” Jones said.

Jones recommends that pond owners keep the following fertilizat­ion tips in mind:

■ Typical fertilizat­ion rates range from 0.5 to 1 gallon per acre for liquid fertilizer­s and 4 to 8 pounds per acre for powdered or granular fertilizer­s.

■ Ideal pond plankton bloom density should result in 18 to 36 inches of visibility. Once the water visibility is within that range, do not fertilize again until the water clears to more than 36 inches of visibility.

■ Overfertil­ization is dangerous. It can lead to aquatic weed problems, potentiall­y harmful blue-green algae blooms and major fish kills.

“Consider your options and goals before you start your spring pond management work,” he said. “Ask for help if you want or need it. And be sure to enjoy your aquatic playground as we finally welcome back the spring fishing season.”
