Enjoying Catch and Fishing Effort: The Effort Effect in Recreational Fisheries

Environmental and Resource Economics, 2013
Recreational fishermen derive utility from catch and fishing effort. Building our analysis on the Gordon-Clark model for renewable resources, we show that a lower importance of catch may result in higher catches. While this effect also holds under first-best management, it may destabilize open-access recreational fisheries to the point of stock ...

Assessing fish sampling effort in studies of Brazilian streams

Scientometrics, 2020
Neotropical stream fish assemblages have attracted much scientific attention in recent decades. However, spatial and temporal patterns in sampling, and the types of methodologies being used in studies, remains unclear. Here, we conducted an in-depth review of the published literature on Brazilian stream fish assemblages, recording where and how these ...

Further Notes on Fishing Mortality and Effort

Copeia, 1944
ECENTLY Dr. Milner B. Schaeffer (1943) has made a contribution to our knowledge concerning the relationship between fishing effort and fish mortality. His results lead him to suggest that parts of the writer's 1940 paper, on the same general topic, stand in need of revision.

Abstract A time‐series regression analysis of data from 1975 to 1995 showed no statistically significant relationship between number of catchable or subcatchable coldwater fish stocked and number of resident and nonresident season licenses sold. Stocking of warmwater subcatchables was a significant determinant of resident season license sales, although
