Commercial fishing is one of the least safe occupations. Fishing vessel accident probability and vessel trip probability for fishing areas off the northeastern United States were modeled using logit regression and daily data from 1981 to 2000. Fishing vessel accident probability declined over the study period. Higher wind speeds are associated with greater accident probability. Medium size vessels had the highest accident probability before 1994. Within the study region, accident probability was lower in Southern New England and Mid-Atlantic waters than on Georges Bank and in the Gulf of Maine. Accidents are more likely to occur closer to shore than offshore. Accident probability is lower in spring and fall. Changes in fishery management in 1994 have not lead to a general increase in either accident or vessel trip probability. Although higher economic payoff (i.e., revenue of landings) induces more vessels to go fishing, this is not associated with an increase in accidents. The probability models are important building blocks in development and quantitative assessment of management mechanisms related to safety in the commercial fishing industry.

“…We developed three separate model runs. The model was first applied to the data for the entire study period (Model I: 1981(Model I: -2000, and then to examine the impact of regulatory changes after 1994, re-applied the model using pre-1994 data (Model II: 1981-1993) and post-1994data (Model III: 1995-2000, respectively.…”

Anticipating the Growth of an Ocean Aquaculture Industry

Aquaculture Economics & Management

& In assessing the future expansion of aquaculture in coastal-ocean environments, most studies focus only on the constraint posed by the local environmental assimilative capacity. In open-ocean environments, however, the assimilative capacity is difficult to gauge. We develop an alternative economic approach for projecting the growth of the open-ocean aquaculture industry. We evaluate equilibria in the market for seafood, where the product may be supplied either by a wild-harvest fishery or open-ocean aquaculture or both. In our framework, the net demand for farmed fish determines the size of the aquaculture industry and, in turn, the levels of pollution discharges. We illustrate our approach with a case study of a groundfish fishery and the proposed open-ocean aquaculture of Atlantic cod in New England. We find that, for a range of competitive production costs for aquaculture, the optimal industry structure would comprise both a wild-harvest fishery and aquaculture.

“…Our approach is designed to be used to characterize the existing economic and ecological conditions and to demonstrate the potential wealth to society that may be derived from the consumption of marine resources, goods, and services associated with a well-managed marine ecosystem (cf. Edwards & Murawski, 1993). The framework can be used to assess the change in wealth associated with changes in the quality and quantity of natural and environmental resources in the ecosystem and the distribution of these changes across industries and consumers.…”

Aquaculture and Capture Fisheries: A Conceptual Approach Toward an Integrated Economic-Ecological Analysis

Aquaculture Economics & Management

2012

This study presents a framework for analyzing the interactions between aquaculture and capture fisheries in the context of ecosystem-based management. We extends a model of the economic and ecological systems in coastal New England by incorporating an aquaculture sector in a computable general equilibrium (CGE) model and by examining the forage fish and aquaculture link in a marine food web. We show that aquaculture and commercial fisheries interact in a complex way throughout the economic and ecological systems.
