Q: Should I put catfish in my pond?
Francis – Avalon, WI
A: Of all the fish species you could stock in your pond, catfish is an excellent choice. These bottom dwellers live in inland or coastal water on every continent, except Antarctica, and include some of the most varied fish on the planet. Channel catfish, the most common type stocked for sport fishing, thrives in shallow waters like your pond or lake.
Catfish are well known for being scavengers. They’ll eat just about anything they can find on the bottom of a pond. Their anatomy makes this task easy – they are negatively buoyant, which means that they generally sink rather than float thanks to a small gas bladder. Catfish also sport a flattened head that allows for easy digging through debris, a mouth that acts as a substrate suction and a body covered in taste buds.
To supplement the natural diet of the catfish in your pond, we recommend adding Pond Logic® EcoBoost™. It adds more than 80 trace minerals to the water, promoting the fishes’ health and speeding their growth. We also suggest feeding Game Fish Grower Fish Food to ensure your catfish have enough food and to increase their overall size.
Channel catfish prefer warmer water (about 60° to 70°F) in areas with little or no currents. They thrive in small and large rivers, reservoirs, natural lakes and ponds. Channel cats are cavity nesters, meaning they lay their eggs in crevices, hollows or debris, to protect them from swift currents.
In your pond or lake, catfish won’t reproduce if they lack an adequate spawning structure. We suggest adding a Porcupine® Fish Attractor to help improve fishing conditions and provide an attractive habitat for catfish to spawn and grow.
Because these guys are bottom dwellers, they can stir up a lot of debris or clay. That will contribute to cloudy, murky water. Aeration can help. Airmax® Aeration Systems increase the oxygen in your pond, circulate the water, promote the colonization of beneficial aerobic bacteria and help maintain clear water.
Ultimately, your decision comes down to personal preference. Catfish are well suited for pond life. They have little effect on the predator-prey relationship in freshwater environments compared to predators like bass or prey like bluegills. Plus, they make for good fishing.
