i get this question alot when i fish with new people, so i figured i would put something up about keeping your own live bait. i have 2 fish tanks setup for keeping live bait. one is for fish, it is a 30 gallon-tall aquarium. in it i keep gold fish, minnows, various perch, bullheads, etc. the other is a 15 gallon-long, for crawdads. you must keep crawdads seperate from your bait fish due to the fact that they will eat anything they can grab. trust me on this, i have seen one craw take down a 5 inch perch. now as far as feeding them is concerned. i feed my craws from a bag of frozen vegtables that i buy from walmart. very easy and cheap. the only words of caution i can give is to find a veggie mix that has NO carrots in it. carrots will eventually turn your water orange, thick, and sometimes toxic. an additional food source is my tank of fish. whenever i get a dead one or two i toss them into the craw tank and they make quick work of it. craws are hearty and very hard to kill....in my opion. for the bait fish tank, i use to cut up worms to feed these guys, however i have found an easier (less messy) way of feeding them. as the perch dont seem to take regular fish food, i use a pond flake that they eat up really fast. it is a product called "wardley pond flake food". a can of this will run about 5 bucks at walmart, and all the fish will eat it. now as far as the water goes, you want to make sure you use a chemical that will remove chlorine from tap water when ever you fill or add water to a tank. a successful way to help stabalize your water culture is to periodacly add river water to your mix. the river water actually contians various bacteria that river or lake fish need to maintian good health. it also helps aclimate any baitshop baitfish to the river water. i keep my ph balance in the 7.5 to 8.0 range (ph is the measurement of acidic or alkalie content in the water). it sounds like its alot of work, but i promise its very simple, and on days when the baitshop is out of your favorite live bait, you will be set to jet. if you have kids its also a great way to keep them busy. you just give them some worms, show them how to bait the hook (if they are old enough) and send them out to fill your tank. now dont let them get to many. to many fish in the tank can cause amonia levels to spike and the water WILL become toxic. the end result will be a lot of dead fish. good luck, be safe, any questions just ask.
