overflow, thereby reducing the total amount of water available to hold dissolved oxygen relative to the biomass of the fish. When this happens you’ve exceeded the carrying capacity of your livewell and the end result will be dead shrimp. If your boat has two livewells you can counteract this biomass problem by splitting your live shrimp or two slot reds among two different livewells. One final method of counteracting this reduction in dissolved oxygen caused by water displace- ment is direct oxygen injection. If you’ve seen the Aquarium of the Americas fish transport tank in action at one of the many Redfishing tournaments we have here throughout the summer, you probably noticed the large welding bottles at the front of the transport tank. Those oxygen cylinders are plumbed to diffusers throughout the tank emitting tiny dissolved oxygen bubbles continuously maintaining a high level of dissolved oxygen in the tank regardless of the high biomass of Redfish that are in that tank. Oxygen tanks of various small sizes can be rented or purchased and refilled by local welding suppliers like AirGas. Regulators can be purchased there as well and hose and diffuser stones can be obtained at any local aquarium store like Petsmart. The final ingredient I like to use is a product called Rejuvenade made by Bass Medics (www.bassmedics.com). When this powdered prod- uct is added to the livewell it can enhance the chances that the fish will stay alive by rejuvenating the slime coat and adding lost electrolytes, like salt, to the fish. You should add one capful of the powder to the livewell at the beginning of the day, right after first filling the livewell, before adding your bait or tournament fish. There are many other livewell gimmicks out there like: adding Hydrogen peroxide, or Potassium permanganate, or electrolytic devises that break water molecules into Hydrogen and Oxygen, but I haven’t found anything more reliable for maintaining the health of your livewell, and therefore your expensive bait or tournament winning fish, than the straightforward steps outlined here. If you can keep your livewell clean, cool, and well oxygenated you have the recipe for beating the heat this summer.
