Heres how I see it fellows Keeping shad alive in the summer is a seasonal problem, same old problem every summer and same old recommendations to keep them alive that doesnt work and never has worked. The cost of catching and keeping shad is staggering in the summer, time, fuel, rest and fleeting success. Many hours over a fishing season is wasted getting up before daylight and throwing that net every day not counting the hours/days of sleep lost because it dies fast and you got to stop fishing and go catch another batch of shad if you can find them again, but dead bait isnt to bad if thats what you want to fish with. The big question is: Do you want to fish with dead shad or live healthy shad? Have you ever added up how many hours you waste throwing that net every season, or 2 seasons, 3 seasons, or even the rest of your life and you still end up with dead bait in the summer? Every summer I hear and see this same problem, shad are delicate baits, you cant keep them alive regardless of what you do, they die within minutes after netting, shad get the red-nose, their scales flake off, yada, yada, yada. We all know the routine, been there and tried that. I hear and see the same old recommendations that engenders hope hope doesnt cut it and hope does not work. The bait still gets red-nose, pipes, then gets lethargic and dies within minutes after catching it and putting it into Super Bobs [brand] Bait Tank with the All-Pro [brand ] aerator. Every summer we hear and see the SOS, so lets examine this a little more. What really causes this high seasonal shad kills in our death-tanks every summer and can this problem ever be corrected enough to keep shad alive and all day in a bait tank? Bait tank sellers sell bait tanks. Over the years salesmen and fishing article writers have convinced shad fishermen that the problem is the brand of bait tank and the solution is buy this brand or that brand of tank. They claim round tanks are the answer because shad are stupid little fish that get trapped in the corners of rectangle or square corner tanks and suffocate. Even though shad may have small primitive brains, they certainly are not ignorant little fish and they do thrive in 90-95 degree lake water every day with no problems. Shad avoid poor water quality if the can and have no choice when caught and end up in a fishermans bait tank. The point is to baffle fishermen with BS and sell more bait tanks. Other salesmen sell and promote the use of ice and livewell A/C units and say chill the livewell water. When you net them in 86 degree water, chill that bait tank water to 65 degrees, they will live a few minutes longer. They never mention how quickly nice chilled shad die when hooked up and tossed back into that hot 86 degree water, (temperature shock). When you chill lake water from 86 degrees down to 76 degrees the oxygen concentration increases 8/10 of 1 part per million. Add slat or bait saver chemicals and it the chill may only increase the oxygen concentration 5/10 of 1 part per million. Salted water (added bait saver chemicals) holds even less O2 than fresh non salted water, more salt = less dissolved oxygen. Buy more ice or an A/C unit. Bait saver chemical salesmen sell expensive colored bait saver chemicals and have convinced many fishermen that their expensive brand of bait saver chemicals are the answer. When the blue water is flushed out, add more blue chemicals, in other words, buy more green chemicals. Bait pump salesmen sell water pumps and claim fish waste, ammonia, CO2, acid water is the problem that kills shad so quickly and you need a high flow of water pumped through the bait tank to flush out toxic waste in the water. Bigger higher volume bait pumps = longer survival time and better shad health. The pump must be big, big enough to totally exchange the bait tank water every 30 seconds, that more flush is better. Two pumps are better than 1 pump. Buy more pumps. The bait tank filter salesman sell particle filters that filter out excessive scale, slime and fish dunk the big chunks of stuff in the water. They dont filter out the deadly stuff you cant see like ammonia, CO2, nitrites or acid in the water. Buy better particle filters, may a double filter. Buy more filters. The problem and killer is low oxygen concentrations. Correct this problem and you can keep shad alive and healthy every summer when the water gets hot. Dont correct the low oxygen problem in the bait tank and live with dead shad Oxygen is the limiting factor in any bait tank, but air is free right? Add up all the cost of bait tanks, water pumps, aerators, batteries, ice, chemicals, dead bait, etc. and then you find out that that air is not as free as you might think and that more air does not mean enough theres going to be enough oxygen to survive. Aerators pump air, not oxygen Bait pumps pump water, not oxygen A fish hatchery manager told me that air is the reason shad die in bait tanks in the summer. Hes an expert transporting live, healthy fish. http://www.oxyedge-chum.com/oxygen_is_not_air.htm Knowledge and the application of that new knowledge and new technology will convert any bait-box from a dead-well to a live-well that really works.
