  Citation × Citation Citation Abstract Copy Title: Fishermen, Markets, and Population Diversity Author: Sanchirico, James N., Jardine, Sunny Fishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity, targeting populations within a species can impact population diversity, and targeting valuable species can impact biodiversity at the ecosystem level. The natural science and economics literatures, however, have given little attention to the impact of fishing on population diversity, even though population diversity is directly linked ecosystem services and estimates of population extinction rates are three orders of magnitude higher than species extinction rates. Here we develop a stochastic bioeconomic model that links the harvest of multiple salmon populations by a single commercial fishery to the trajectory of population diversity in a salmon stock complex. We parameterize our model with biological and economic data from the Copper River Chinook salmon fishery. We show that markets can incentivize the degradation of population diversity, reducing infra-marginal fishery rents and increase the variability in financial returns to the fishery. Factors impacting the magnitude of our results include the level and distribution of harvesting efficiency and market conditions. We also show that second-best management can conserve population diversity and improve welfare. Furthermore, depending fishermen’s time preferences, this management strategy is potentially self-financing.

  Citation × Citation Citation Abstract Copy Title: Biosecurity vs. Profits: A Multi-Objective Model for the Aquaculture Industry Author: Estay-Montecinos, Manuel, Dresdner-Cid, Jorge In this paper we measure the value of sanitary restrictions in terms of forgone profits. For this we model the trade-off between biosecurity and profits in the salmon aquaculture industry. We introduce the concept of “sanitary desirable volume” of the salmon industry, as a goal in a bi-objective model. We are able to optimize this model, using base information relevant for the Los Lagos Region in Chile, and identify a Pareto Frontier. Within this setting we analyze the shadow price of one objective in terms of the other, the effect of changes in the administrative regulations that limit fish density in the farms, and of prices on the Pareto frontier. We find that the effect of sanitary restrictions in terms of forgone profits is quantitatively important and that this effect is dependent on the level of sanitary restrictions and on the relative product prices. This has important implications for the design of sanitary restrictions. The level of the sanitary desirable volume should be determined carefully to avoid costly excessive regulation. Moreover, market conditions can also affect the optimal level of regulation.
