Creels - Aren't They Old Fashioned Fish...by: Bob Wattendorf, with Jason Dotson (View Article Source)
A creel is a wicker basket used for holding fish that an angler has caught, or a wicker fish trap. Today, we still use the expression derived from that old-fashioned, but very stylish, basket. Somehow we haven’t adapted to asking if we can do “a live-well,” “ice-chest” or “catch-and-release survey.”
The FWC’s fisheries biologists need to know what you have been catching. Despite using old-fashioned terminology, the sophistication of these vital surveys has grown over the years, and they are now a critical source of information for determining how Florida’s fisheries are doing.
Since creel clerks who conduct these interviews cannot talk to every angler, biologists and statisticians work together to carefully determine a sampling scheme of when and where we momentarily interrupt an angler’s recreation to gather this information. Each angler asked to participate represents many other anglers that we cannot talk to, so it is very important that we get the most accurate information possible. The interviewer will want to know how long you’ve been fishing, and what you caught and harvested as well as what you released. They may also measure your fish, check them for tags and ask some questions about where you live and other information that helps to explain results, including information on your age, which for instance relates to license sales.
Of course, biologists consistently use multiple sources of data to reduce the chance these types of errors will occur. But with recurring budget cuts, creel surveys and angler-attitude surveys become increasingly cost effective. As other options, such as electrofishing, seining or trawling, are reduced to save money, or sampling, such as block nets and gillnetting, are reduced because of adverse public perception, the need for honest, accurate answers to creels surveys becomes more and more important.
In 2007-08, FWC estimated fisheries dependent effects of sportfish catch, harvest, effort and success rates from creel survey data collected from 14 freshwater bodies throughout the state. Of the three primary sportfish types (black crappie, sunfish and largemouth bass), most anglers once again pursued largemouth bass (averaging 27 hours/acre/100 days). The 100 days refers to the peak spring fishing season, so multiplying by 3.65 to get an annual rate would yield an over estimate, which is an example of scientists trying to keep the data “real” and to standardize it so you can compare between water bodies. Some other highlights include the fact that anglers caught the most bass per acre from the L-67A canal (76 bass/acre) and the Stick Marsh (14 bass/acre), whereas a typical figure is less than 10 bass/acre. The canal fisheries benefits from concentrating fish from the Everglades, so the per acre calculation can be a little misleading, but it is nonetheless an outstanding recreational asset. It is important to note that less than 10 percent of those were harvested (removed from the system, the others were released). Catch success ranged from 0.32 bass/hour (Lake Harris) to 1.19 bass/hour in the L67A. Often a figure of 0.25 bass/hour (meaning one bass caught per angler every four hours on the water) is considered typical in the U.S., with experienced anglers doing much better but the average influenced by the many novices and those casually fishing more for the relaxation then to compete for the most bass.
The Stick Marsh (33 hours/acre/100 days) and Lake Lochloosa (21 hours/acre/100 days) provided the most concentrated fishing effort for black crappie, but catch rate was highest for Lake Tohopekaliga at 2.33 fish per angler-hour. Lake Okeechobee, the international crappie fishing Mecca, has been somewhat less productive recently due to major habitat and weather-related effects. It produced 5 hours/acre/100 days of crappie fishing in the northwest area of the lake, with a catch rate of 1.49 fish per angler-hour. The greatest focused effort and harvest for specs (51 hours/acre/100 days) was observed at L-67A canal, while the “Big O” led the way with a 4 sunfish per angler-hour catch rate. The Stick Marsh/Farm-13 supported the most fishing pressure for catfish (4 hours/acre/100 days) and was second only to Lake Istokpoga (1.3 fish per angler-hour) in catfish catch rates.
So the next time someone tells you they are conducting a creel survey, remember you are representing many anglers and helping to ensure the safe and sustainable future of quality recreational fishing in Florida when you give a few minutes of your time and accurate information to the creel clerk.
