“…For example, a coarser survey design would have provided angling effort and a CPUE for the entire complex and we would have missed that relationship between angling effort and CPUE at the individual lake, which has implications on how angling effort could be managed in this system of lakes (Martin and Pope, 2010) and increase the resiliency of the fishery (Post, 2013). Furthermore, the creel survey used in this study revealed that anglers rarely move among lakes during a single trip; that is when an angler decides to fish at a given lake they stay at that lake during the fishing trip.…”

a b s t r a c tSpatial layout of waterbodies and waterbody size can affect a creel clerk's ability to intercept anglers for interviews and to accurately count anglers, which will affect the accuracy and precision of estimates of effort and catch. This study aimed to quantify angling effort and catch across a spatially complex system of 19 small (<100 ha) lakes, the Fremont lakes. Total (±SE) angling effort (hours) on individual lakes ranged from 0 (0) to 7,137 (305). Bank anglers utilized 18 of the 19 lakes, and their mean (±SE) trip lengths (hours) ranged from 0.80 (0.31) to 7.75 (6.75), depending on the waterbody. In contrast, boat anglers utilized 14 of the 19 lakes, and their trip lengths ranged from 1.39 (0.24) to 4.25 (0.71), depending on the waterbody. The most sought fishes, as indexed by number of lakes on which effort was exerted, were anything (17 of 19 lakes), largemouth bass Micropterus salmoides (15 of 19 lakes), and channel catfish Ictalurus punctatus (13 of 19 lakes). Bluegill Lepomis machrochirus, crappie Pomoxis spp., and largemouth bass were caught most frequently across the lakes, but catch rates varied considerably by lake. Of the 1,138 parties interviewed, most parties (93%) visited a single lake but there were 77 (7%) parties that indicated that they had visited multiple lakes during a single day. The contingent of parties that visited more than one lake a day were primarily (87%) bank anglers.. The number of lake-to-lake connections made by anglers visiting more than one waterbody during a single day was related to catch rates and total angling effort. The greater resolution that was achieved with a lake specific creel survey at Fremont lakes revealed a system of lakes with a large degree of spatial variation in angler effort and catch that would be missed by a coarser, system-wide survey that did not differentiate individual lakes.

“…Reservoir drawdowns can also aff ect anglers, including loss of boat ramp availability, loss of amenities for bank anglers, and changes in catch or harvest rates (Heman et al 1969;Post 2013). During periods of low water, anglers can choose to take up a diff erent recreational activity (e.g., golf), choose to continue fi shing at the reservoir and maintain their behavior, choose to continue fi shing at the reservoir but alter their fi shing behavior, or choose to fi sh a substitute reservoir within a regional fi shery (Martin and Pope 2011).…”

“…Recreational harvest is an integral component of most inland fisheries in North America, Europe, and Australia that affects population viability, community interactions, and fishery quality (Isermann and Paukert, 2010;Post, 2013). As such, regulating the harvest of fish by anglers is a common practice within fishery management.…”

Self-imposed length limits in recreational fisheries

et al. 2014

a b s t r a c tA primary motivating factor on the decision to harvest a fish among consumptive-orientated anglers is the size of the fish. There is likely a cost-benefit trade-off for harvest of individual fish that is size and species dependent, which should produce a logistic-type response of fish fate (release or harvest) as a function of fish size and species. We define the self-imposed length limit as the length at which a captured fish had a 50% probability of being harvested, which was selected because it marks the length of the fish where the probability of harvest becomes greater than the probability of release. We assessed the influences of fish size, catch per unit effort, size distribution of caught fish, and creel limit on the selfimposed length limits for bluegill Lepomis macrochirus, channel catfish Ictalurus punctatus, black crappie Pomoxis nigromaculatus and white crappie Pomoxis annularis combined, white bass Morone chrysops, and yellow perch Perca flavescens at six lakes in Nebraska, USA. As we predicted, the probability of harvest increased with increasing size for all species harvested, which supported the concept of a size-dependent trade-off in costs and benefits of harvesting individual fish. It was also clear that probability of harvest was not simply defined by fish length, but rather was likely influenced to various degrees by interactions between species, catch rate, size distribution, creel-limit regulation and fish size. A greater understanding of harvest decisions within the context of perceived likelihood that a creel limit will be realized by a given angler party, which is a function of fish availability, harvest regulation and angler skill and orientation, is needed to predict the influence that anglers have on fish communities and to allow managers to sustainable manage exploited fish populations in recreational fisheries.
