Maximum size of fish caught with standard gears and recreational angling

Abstract

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these two methodologies. At present, one cannot reliably predict the maximum size of fishes that is likely to be caught with angling given the maximum size of fishes captured with standard gears during routine monitoring of a fishes population.

“…Recreational fisheries on wild populations may become more valuable if the abundance of ''trophy'' fish (i.e., the frequency of large fish conferring high social status to anglers and economic value to the recreational fishery [72] increases with average body size).…”

“…The study found that angling selected for a larger maximum length of fish and often greater maximum size of fish than the other gears examined (Pope et al. ). The use of angling as a sampling gear could be beneficial for researchers who are interested in getting a more representative sample of the trophy‐sized individuals in a population (Pope et al.…”
