Abstract:

\n

Histor ically\, fisheries management has focused on single-species approaches and largely overlooked multispecies and economic interactions. Failure to acc ount for these linkages has led to suboptimal yields and overfishing. Mode rn Portfolio Theory\, a financial framework based on the principle of dive rsification\, provides a novel perspective for addressing these challenges . In finance\, diversification benefits arise when individual assets (e.g. \, stocks\, bonds\, cash) in a portfolio exhibit imperfect and offsetting correlations\, thus reducing total portfolio variability to less than the weighted sum of individual asset variabilities. Applied to fisheries\, fis h stocks can be thought of as revenue-producing biological assets\, with r evenue covariance occurring between species due to interacting biological\ , technical\, and economic dynamics. Fishery managers may leverage contemp orary financial and economic methods to gain insight into regional fishery dynamics and explore harvest strategies that reduce financial risk for th e fishing industry. This dissertation demonstrates practical applications of these quantitative methods for multispecies fisheries management. Chapt er 1 advances recent work on applications of Modern Portfolio Theory throu gh a New England region case study. While supply-side biomass dynamics are frequently studied in fisheries science\, demand-side ex-vessel prices ar e scarcely incorporated outside of the economic field despite strongly inf luencing revenue determination. Chapter 2 applies economic methods to anal yze common trends in ex-vessel price shocks and their portfolio implicatio ns. Chapter 3 proposes a framework adapting Modern Portfolio Theory and ot her common financial metrics as a suite of indicators that describe the ec onomic state of the region’s fisheries. Together\, these chapters seek t o advance the integration of economic tools and objectives into management practices to achieve more holistic outcomes.
