Abstract

Sound natural resource management considers the full range of costs and benefits of policy action. Understanding these implications as they pertain to nonmarket goods or externalities requires an accurate assessment of consumer preferences and behavior. The chapters of this dissertation ascertain this knowledge in the context of recreational Atlantic striped bass fishery management and offshore wind development in the northeast United States. Atlantic striped bass are the most prominent and heavily targeted recreational species found along the coast from Maine to North Carolina. Yet due in part to heavy recreational fishing effort, the species may be currently overfished. Given this status, it is pertinent to explore the concurrent impacts of potential policy action on angler participation, angler welfare, and recreational fishing mortality such that efficient compromises between conservation and socioeconomic objectives of fisheries management can be made. In Chapter 1, we evaluate the economic incentives faced by recreational striped bass anglers using data from a recently-administered recreational striped bass angler survey. We estimate angler preferences for and the nonmarket value of keeping and releasing small (22”), medium (29”), and trophy-sized (38”) fish. We find that for each size-class, anglers prefer keeping to releasing striped bass and that the nonmarket value of Atlantic striped bass increases exponentially with catch size. Illuminating the tradeoffs made by recreational striped bass anglers, our results indicate that one harvestable trophy-sized fish can be exchanged for about two medium-sized or three small ones. Chapter 1 also sheds light on an important issue that arises when using discrete choice experiment data to evaluate angler preferences; namely, the influence of including versus excluding catch-and-release regulations on ensuing parameter estimates in models of angler utility. We find that failing to control for such regulations leads to counterintuitive estimates of the marginal utility of releasing striped bass. Finally, while choice experiment survey data is used extensively in the literature on recreational demand modeling, little attention has been paid to survey non-response bias on welfare estimates. We spearhead this issue using data collected from survey non-respondents during a telephone pre-screening interview. In Chapter 2, we integrate the main results from Chapter 1 and historical catch data into an aggregate demand model to examine the broad effect of recreational striped bass fishing policies. We simulate the recreational Atlantic striped bass fishery and measure the relative effect of alternative sets of fishing regulations on angler welfare, angler participation, fishing mortality, and mature female

Highlights

  • The status of Atlantic striped bass as the most prominent and heavily targeted recreational species found along the coast from Maine to North Carolina is represented poorly by the absence of studies addressing the policy-relevant economic research questions posed by the fishery’s governing body

  • Coastwide harvest of Atlantic striped bass in 2015 was reduced by 22.4% relative to 2012 levels, and all sectors achieved or exceeded their harvest reduction goal except for the Chesapeake Bay recreational sector, within which harvest increased by 53.4% relative to 2012 (ASMFC 2016b)

  • In line with the results from choice experiment studies focused on other recreational species, model estimates indicate that anglers place a higher value on striped bass that may be kept than on those that must be released

Summary

Introduction

The status of Atlantic striped bass as the most prominent and heavily targeted recreational species found along the coast from Maine to North Carolina is represented poorly by the absence of studies addressing the policy-relevant economic research questions posed by the fishery’s governing body. A few previous studies estimate the nonmarket value of catching additional striped bass (U.S EPA 2004; Gautum and Steinback 1998; Bockstael et al 1989), but due to data limitations, these studies do not examine how recreational anglers value fish they keep relative to fish they release nor assess the extent to which these values vary with catch size Results of these studies provide little insight into the implications of changing recreational Atlantic striped bass fishing regulations. Recreational fisheries managers often attempt meet short-run conservation objectives by adjusting daily possession and size limit regulations These policy actions influence aggregate recreational fishing demand by altering the incentives faced by individual anglers. The model is parameterized with the results of a recent choice experiment survey, where angler participation and welfare are conditional on trip cost and the number and size of striped bass kept and released It simulates the fishery under actual 2015 policy conditions, imposes alternative 2015 bag and size limits, and calculates resultant changes in angler welfare and demand.
