“…The size distributions of yellow perch caught by anglers changed significantly between 2010 and 2011 (i.e., fewer large fish during 2011) but still fell within ranges observed in other studies (e.g., Isermann et al, 2005). We observed the strongest change in the self-imposed length limit for yellow perch, but it is unknown whether this was from the change in the creel limit or change in the available size structure.…”

“…The self-imposed length limits corresponded to sizes observed in other studies that assessed sizes of harvested fish (e.g., Colvin, 2002;Paukert et al, 2002;Isermann et al, 2005;Holley et al, 2009). For example, Isermann et al (2005) found that the mean minimum length of yellow perch harvested by anglers ranged from 21 to 26 cm, depending on the South Dakota lake assessed. In our assessment, the self-imposed length limit ranged from 24 to 33 cm, depending on the year assessed.…”

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.

“…Angler size selectivity has been previously documented for yellow perch fisheries (Isermann et al 2005). Isermann et al (2005) documented that the mean minimum total length of yellow perch harvested in a South Dakota lake was 212 mm, indicating anglers set self-imposed minimum length limits without regard to mandated limits.…”

“…Isermann et al (2005) documented that the mean minimum total length of yellow perch harvested in a South Dakota lake was 212 mm, indicating anglers set self-imposed minimum length limits without regard to mandated limits. The combination of female-biased SSD with size-selective angler behavior creates the potential for female-biased harvest (Schoenebeck and Brown 2011).…”

“…Therefore, length limits are often used to restrict the harvest of certain size classes of fish (Cook et al 2001;Isermann et al 2007). Even when length limits are not set by the managing natural resource agency, anglers have been shown to be size selective by setting personal minimum length limits and voluntarily harvesting longer or more robust individuals (Goedde and Coble 1981;Parsons and Reed 1998;Isermann et al 2005). Therefore, minimum length limits exist, whether dictated by a natural resource agency or self-imposed by anglers.…”

Size-selective angler behavior or the implementation of length-based regulations may have implications in harvest-oriented yellow perch (Perca flavescens) fisheries where perch populations may display sexual size dimorphism (SSD), even though the occurrence of SSD remains poorly documented. Predicted and observed mean lengths-at-age were used to describe the occurrence of yellow perch SSD in populations from four states and one Canadian province. In addition, abiotic and biotic variables were used to predict the occurrence of SSD in yellow perch populations. Predicted mean lengths-at-age were significantly greater for female yellow perch after age 3 indicating female-biased SSD (higher female growth rates and greater maximum attainable lengths) occurred upon maturity. Using observed mean lengths-at-age, 85% of the study populations had at least 1 year class where females were significantly larger than males. Femalebiased SSD was present in almost two-thirds of the individual observed mean length-at-age year class comparisons. SSD could not be reliably predicted using yellow perch population dynamics or lake morphometry. Although, yellow perch SSD was positively correlated with lake productivity, a low fit statistic suggests a poor predictive relationship. This study has demonstrated the prevalence of female-biased SSD in yellow perch populations. Because yellow perch anglers are size selective and harvest oriented, the occurrence of female-biased SSD in a perch population will likely result in female-biased exploitation and, therefore, we recommend natural resource agencies collect age and gender-specific data to identify the occurrence of SSD in perch populations.

Impacts of invasive fish removal through angling on population characteristics and juvenile growth rate

Exploitation can modify the characteristics of fish populations through the selective harvesting of individuals, with this potentially leading to rapid ecological and evolutionary changes. Despite the well-known effects of invasive fishes on aquatic ecosystems generally, the potential effects of their selective removal through angling, a strategy commonly used to manage invasive fish, are poorly understood. The aim of this field-based study was to use the North American pumpkinseed Lepomis gibbosus as the model species to investigate the consequences of selective removal on their population characteristics and juvenile growth rates across 10 populations in artificial lakes in southern France. We found that the maximal individual mass in populations decreased as removal pressure through angling increased, whereas we did not observed any changes in the maximal individual length in populations as removal pressure increased. Total population abundance did not decrease as removal pressure increased; instead, here was a U-shaped relationship between removal pressure and the abundance of medium-bodied individuals. In addition, population biomass had a U-shaped curve response to removal pressure, implying that invasive fish populations can modulate their characteristics to compensate for the negative effects of selective removals. In addition, individual lengths at age 2 and juvenile growth rates decreased as removal pressure through angling increased, suggesting a shift toward an earlier size at maturity and an overall slower growing phenotype. Therefore, these outputs challenge the efficiency of selective management methods, suggesting the use of more proactive strategies to control invasive populations, and the need to investigate the potential ecological and evolutionary repercussions of nonrandom removal.
