Casting nets are available in monofilament and multifilament and diameters 6 to 16 feet. Cabela's also carries a one man seine which will stand by itself allowing the seiner to walk through the water herding fish toward the net. I have also used it as a push seine in streams, but have only found it effective in dead-end channels or small, landlocked pools. The heavy buckets and coolers used to transport fish stay with the car and are only removed to add water or the troller's contents when I'm finished. Bait buckets come in several types, but should be insulated to transport fish on very warm days.
Some buckets even come equipped with self-contained aeration systems.
I rarely if ever use bait buckets anymore, preferring instead food coolers such as Gott, Thermos, and Coleman. Many have excellent locking tops which keeps leaks from splashing water to a minimum. Otherwise, I use bungee straps which work just as well. I have tried Cabela's Deluxe Minnow Aerator and though it may have been defective, I was not satisfied with the air output. DC water pumps are very similar to aquarium powerheads and circulate water through an adjustable spray tube.
