  Citation × Citation Citation Abstract Copy Title: Modeling Heterogeneous Fishing Fleet in an Ecosystem Based Management Context Author: Hutniczak, Barbara Multispecies fisheries pose a considerable management difficulty with respect to quota allocation between species. Externalities of direct control over the harvest may include, among others, creation of unbalanced predator‐prey relationships in the environment. That, in turn, may affect the individual economic incentives of fishing vessels. Combining economic and ecological factors in one model has multiple advantages, whereas there have been little attempts to coordinate setting the total allowable catches in multispecies fisheries, particularly in the context of individual decision‐making process. The objective of this article is to develop a methodological framework for multispecies modeling with integrated ecological and economic realism suitable to evaluate the long term implications of the imposed regulations that can be used for better policy guidance. An empirical application is provided for the central Baltic Sea with its interacting fish community dominated by three species: cod, herring and sprat. The developed model includes three separate, dynamically updating, age‐structured submodels for each species, which are linked through predation. The harvest component is associated with the fishing vessels that optimize individual behavior subject to regulations, owned capital and individual technical efficiency derived with the use of a multiproduct distance function. The findings present a clear picture of asymmetries between vessels with respect to harvest process and reveal the rational harvest strategy that is accommodated in the multispecies simulation model.

  Citation × Citation Citation Abstract Copy Title: New England Commercial Ground-fishermen: Adaptation and Transition Author: Murphy, Tammy, Henry, Anna Fishing years 2012 -2013 brought declines in socio-economic performance for the Northeast groundfish fishery. Severe reductions in catch limits for key species such as Atlantic cod have constrained fishing behavior and declining groundfish revenues cannot be offset by non-groundfish revenues earned by the fleet. Little is known about the way groundfish fishermen are making decisions in response to changes in the fishery. We present results from approximately 60 ethnographic interviews with previously active groundfish fishermen who exited the fishery and current active participants who are considering transitioning out of the fishery. Interviews focused on level of participation in the groundfish fishery, changes since the implementation of catch shares and factors that have influenced decision-making around continued participation or exiting the groundfish fishery. The information collected suggests that adaptation strategies and impacts vary considerably with factors such as the fisherman’s age, initial quota allocation, level of debt, and presence of a second earner in the household. We develop a descriptive theory that characterizes actual choices being made currently by New England fishermen, with the goal of improving the ability to predict responses to future regulatory changes. Decision-making processes appear to differ from typical economic models used to analyze proposed regulatory actions. A richer understanding of these decision-making processes will lead to improved analysis of regulatory impacts.
