Striped Bass Catch & Release Tactics
Arkansas Parks and
Tourism Striped Bass Catch & Release Tactics can aid the survival of released striped bass with careful planning, fishing and handling methods. Hooked stripers can die from injury or from the stress of being hooked, fought and landed. Stress-related mortality increases greatly when water temperatures exceed 70F and is also greater in freshwater than in brackish water. Infection and disease can result in mortality of fish whose protective slime coat is removed during handling. The chances that released fish will survive will be increased greatly by following these guidelines. Ideally, fish are landed quickly, handled little, if at all, and kept in the water while the hook is removed using a de-hooker and barbless hooks.

HANDLING AND RELEASING STRIPERS
REMOVING THE HOOK
Learn and practice catch-and-release fishing techniques and teach them to your children and friends. Striped Bass Fiberglass ReplicasWith the increasing popularity of "The Catch and Release Program", you may be forced to make a difficult decision when deciding whether to keep or release that Trophy Fish. You do have the option of taking a photo to prove you had temporary possession of the wall-hanger, which will shore up your credibility when you share your adventure with your friends and neighbors. Another option is Fiberglass Reproduction, which allows you to release the trophy, and keep a mount. A fiberglass fish reproduction is an extremely durable, long lasting alternative to traditional skin mounts. The replica will withstand hot or cold climates and will never deteriorate or shrink. In some cases they are less expensive than a conventional mount. Lactic Acid Build up in Striped BassHigh muscular activity and stress during fighting causes disturbances in fish tissues and organs. These changes occur in the fishes blood and may be severe enough to alter normal physiology and behavior and ultimately compromise survival. In some cases, fish may die, either on the line or more likely after release. Changes in blood chemistry can be compared to several variables which are associated with the fight such as tackle type, fight time, water temperature, and fish size. Findings show that these fish exhibit fluctuations in blood pH and blood levels of hormones, electrolytes, and metabolites due to the fights associated with rod and reel angling. For example, the metabolic byproduct of anaerobic glycolysis is lactic acid. Rough handling of fish, internal hook damage, and excessive time out of water can cause irreparable damage to a fish that is released. Recovery may take days or months if the fish survives at all, and will require a metabolic cost. Physiological stress can be minimized by reducing fight and handling time. However, physical trauma can only be reduced through conscious efforts of anglers when choosing to release a fish. Hook design, handling methods, and experience all play a major role in proper release of Stripers. Air Bladder Of The Striped Bass Striped Bass maintain their relative depth in
the water column by adjusting the volume and pressure of gas in their air bladder in order
to maintain a neutral buoyancy. To maintain equilibrium at increasing depths where the gas
in the air bladder would be compressed, greater gas pressure is required in the air
bladder. Conversely, at shallow depths less pressure is required as the gas in the air
bladder expands. The air bladder occupies approximately 4 to 6% of the total volume of the
fish. Quick vertical movements without adjustment to the rates of secretion of gas
into, or re-absorption of gas from, the air bladder. However the magnitude of these
movements may be related to the depth of the fish. The rapid removal from deep water at a
rate far in excess of the rate that the fish can actively remove gas from the air bladder.
Often the result is an excessively inflated air bladder that may distend the abdomen, or
force the air bladder and gut lining to protrude out of the mouth. The probability of
survival for a fish released with a distended air bladder is not high. The fish may
reabsorb the excess gas in time. The below information is provided by the Oklahoma
Department of Wildlife Conservation about Striped bass like most fishes, adjust their buoyancy so they
can maintain their vertical position in the water without actively swimming.
Stripers adjust their buoyancy by the gas bladder. The gas bladder in fish
operates like a buoyancy compensating device used by a SCUBA diver. As depth
increases and the gas compresses (occupies less volume). To maintain neutral
buoyancy, the fish adds gas to the gas bladder. When the fish ascends,
pressure decreases, the volume of gas in the bladder expands, and buoyancy
increases. Stripers can remove gas from the bladder with the gas gland, but
this a relatively slow process. Therefore, a striper quickly displaced from
deepwater to shallow water is helplessly buoyant and suffers “the bends.”
Behavioral symptoms of stripers with buoyancy problems include fish that
remain at the surface after release and fish that lie on their side or
assume a “head-down” posture.
