Catch And Release
Susan Sabol
Catch and release fishing improves native fish populations by allowing more fish to remain and reproduce in the ecosystem. This practice provides an opportunity for increasing numbers of anglers to enjoy fishing and to successfully catch fish. Releasing native fish caught while in a national park will help to ensure that enjoyment of this recreational opportunity will last for generations to come.
In catch and release fishing anglers immediately release native fish - unharmed - back to the water where they are caught. When done correctly, catch and release methods result in high survival rates. But catching and releasing fish successfully takes practice.
Catch and release fishing is a type of recreational fishing where anglers immediately release a fish back to the water where it was caught. It's a great conservation strategy, but simply letting a fish go does not guarantee it will live. The actions you take before, during, and after you land a fish can improve the chances of survival, keep fish populations healthy, and keep fishermen fishing.
The best way to ensure a fish suffering from barotrauma survives is to release it as quickly as possible at depth. There are a variety of recompression tools you can use, including descender devices, release weights, and release baskets.
Catch and Release is a 2006 American romantic comedy film written and directed by Susannah Grant, her only film as director thus far, and starring Jennifer Garner, Timothy Olyphant, Kevin Smith, Sam Jaeger and Juliette Lewis. In the film, after a woman's fiancé dies, she seeks comfort in his friends, learning his secrets while falling for his best friend. Filming took place in 2005 in Vancouver and Boulder, Colorado. Catch and Release premiered at the Austin Film Festival in October 20, 2006 and was released in the United States on January 26, 2007. The film bombed at the box office, earning $16 million against a $25 million budget.
Gray does not want anything to do with Maureen, but the guys are reluctant to send the son of their dead friend away so quickly, so they all get to know each other over dinner. Trying to understand how Grady could secretly cheat on her, Gray blurts out her belief that "catch and release" fishermen are cruel and should just eat the fish.
Introduction
Fishing effort in Florida has increased dramatically over the past decade and is forecast to continue as Florida's resident population of 14.7 million increases daily by about 1,000 people. More than 40 million tourists visit the state annually, most with coastal destinations. Fishing is a favorite pastime of Florida's residents and visitors, and in 1997, saltwater anglers made about 24 million fishing trips and caught 141 million marine fishes, 71.5 million of which were released. Because increased exploitation could negatively impact Florida fisheries, scientists and managers must remain diligent and innovative in their efforts to utilize fishery resources wisely and conservatively.
Managers of Florida's fisheries use a combination of traditional regulations to control harvests and protect fish stocks. These measures include bag limits, minimum and maximum sizes, closed seasons and areas, and in some cases, no harvest is allowed unless a special permit is purchased. Bag limits reduce the number of fish that are harvested and allocate the catch over time so that the year's total harvest is not taken in one season. Aggregate bag limits are sometimes applied collectively to a complex of species such as grunts and snappers, so that the community is not overfished. Minimum and maximum sizes, or "slot," limits protect sexually immature fish and may be imposed to create a "trophy" fishery, i.e., a fishery that produces extremely large individuals. Closed seasons and closed areas protect a species during spawning, especially when fish return yearly for spawning at known locations. The "no harvest" rule is implemented when a stock or species, for example, Goliath Grouper (jewfish), is severely overfished. To succeed, Florida's fisheries management strategies of size limits and closed seasons depend on the survival of fish that are caught and released. The fate of hook-and-line caught fishes that are released largely depends on the expertise and dexterity of the angler. Anglers practicing a few straightforward and intuitive techniques can increase survival of released fishes.
"Limit your kill; don't kill your limit!"
After being caught and released by an angler, fish may die for a variety of reasons. The most common causes of death are the physiological stresses caused by the struggle during capture and injuries caused by the hook or the angler. Some fish may die even though they appear unharmed and despite efforts at revival. Fish that struggle intensely for a long time during capture are usually exhausted and stressed from the accumulation of excessive amounts of lactic acid in their muscles and blood. Severe exhaustion causes physiological imbalance, muscle failure, or death. Therefore, use the proper weight-class tackle; land your catch quickly, and when possible, leave the fish in the water while you release it. Any exhausted animal needs oxygen to recover!
Hook wounds may appear minor to anglers, but damage to the gills, eyes, or internal organs can be fatal. If the fish is hooked deep in the throat or gut, research shows that it is best to cut the leader at the hook and leave the hook in the fish. Prolonged attempts to remove the hook often do more harm than good. In the Fish and Wildlife Research Institute's (FWRI)* study of release mortality in snook, 24 snook were deep hooked. We removed the hooks from 12 snook, and we left the hook intact and cut the leader in the other 12 snook. We found that four of the 12 deep-hooked snook died after the hooks were removed. None died when we simply cut the leader and left the hook alone. Fish are capable of rejecting, expelling, or encapsulating hooks. Encapsulation is a process whereby the fishes' healing process causes the hook to be covered with an inert matrix of calcified material; or a-cellular tissue. Steel and bronze hooks are less toxic and are rejected or "dissolved" sooner than are stainless steel and cadmium-plated or nickel-plated hooks.
Two types of hooks, barbless and circle hooks, are known to reduce injury and mortality of released fishes. Barbless hooks reduce tissue damage and handling stress because they can be removed quickly and easily. Barbless hooks are popular in the freshwater trout fisheries and are becoming increasingly popular with saltwater anglers. A Florida study conducted on snappers and groupers demonstrated that catch rates are the same for barbed and barbless hooks. If barbless hooks are not available, simply use pliers to crimp or remove the barbs from regular hooks. A caveat is called for when using these types of hooks: after having hooked your quarry, don't give the fish any slack, because it will be more likely to escape from barbless hooks than from regular hooks.
The use of circle hooks has been researched and compared to regular hooks-often called "J" hooks-in several fisheries. In all of them except in the flatfish, or flounder, fishery, circle hooks were shown to result in significantly lower hooking mortality and higher catch rates. In one study, tunas and billfishes were hooked in the jaw 90% of the time. Circle hooks reduced deep hooking fourfold in the striped bass fishery while "J" hooks were 21 times more likely to cause a bleeding injury. Circle hooks are a bit more tedious to use, especially with live bait, but the advantages should compel anglers to give them an honest trial. Overall, research shows that circle hooks improve catch rates and reduce hooking mortality which results in positive impacts on exploited fish stocks.
Survival rates for some Florida fishes
Controlled studies have shown that most fish released after hook-and-line capture, survive. Researchers working in Boca Grande Pass tagged 27 tarpon with sonic transmitters and found that 26 of these hook-and-line-caught fish survived. The one fish that died had been lifted from the water for a prerelease photograph. Scientists repeatedly caught bonefish held in a large pond in the Florida Keys and found that 96% survived capture. A few of the bonefish that ultimately died had been caught five to ten times each, which suggests that bonefish hooked and released in the wild probably have an even higher survival rate. Angler-caught snook held in large net-pens throughout Florida had a 98% survival rate. Most of the snook that died were caught with live bait, consistent with studies showing that fish caught with lures generally survive. Spotted seatrout caught in Tampa Bay had a 95% survival rate. Hook position affected survival rates; trout hooked in the gills or gut had lower survival rates than those hooked in the mouth. Redfish survival rates range from 84% in Georgia waters to 96% in Texas waters. Like seatrout, hook position affected survival rates; more than 50% of the throat or gut hooked fish died. These studies demonstrate that catch-and-release-fishing works-most fish that are released survive. By following a few simple guidelines, anglers can maximize survival rates.
Some guidelines for catch-and-release angling
The most important steps an angler can take to ensure a successful release are to hook and land the fish as quickly as possible, leave the fish in the water while removing the hook, and release the fish quickly. There are several other ways to improve survival rates:
New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today reminded anglers that the State's new catch-and-release trout stream season begins on Oct. 16, expanding recreational opportunities.
"Using science, research, and public input, DEC is increasing fishing opportunities while advancing responsible trout management in order to ensure trout reach their fullest ecological and recreational potential," Commissioner Seggos said. "New York State's new catch-and-release season in trout streams expands opportunities for anglers so they can enjoy the State's trout stream fishing resources year-round."
