Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics is represented “conditionally to” fishing mortality. This mortality must be therefore p...
Classification of working processes to facilitate occupational hazard coding on industrial trawlers.
BACKGROUND Commercial fishing is an extremely dangerous economic activity. In order to more accurately describe the risks involved, a specific injury coding based on the working process was developed. METHOD Observation on six different types of vessels was conducted and allowed a description and a classification of the principal working processes on all kinds of vessels and a detailed classi...
This report presents the findings of a study of subsistence salmon fishing on the Togiak River, southwest Alaska, conducted in 1997 and jointly funded by the Division of Subsistence of the Alaska Department of Fish and Game and the Tog&k National Wildlife Refuge, U.S. Fish and Wildlife Service. The study had two primary goals. The first was to document subsistence salmon fishing patterns by Tog...
There is a growing focus around the world on marine spatial planning, including spatial fisheries management. Some spatial management approaches are quite blunt, as when marine protected areas (MPAs) are established to restrict fishing in specific locations. Other management tools, such as zoning or spatial user rights, will affect the distribution of fishing effort in a more nuanced manner. Co...
CHD mortality is extremely low in Japan, particularly in rural districts, when compared with that in Western countries. This has been partly attributed to the difference in dietary lifestyle. We investigated the factors influencing CHD mortality in a rural coastal district of Japan, comprising mercantile, farming, and fishing areas with distinct dietary habits. We prospectively examined the inc...
Marine debris is recognized as a major threat to biodiversity and can be found ubiquitously even in remote regions, including deep-sea environments. Isla del Coco National Park is known as one of the best protected areas around the world, a preferred diving destination, and is also renowned for large aggregations of pelagic species that attract illegal commercial fisheries. Despite its pristine...
Fishing resources are important generators of income and food for the rural and urban people in the Amazon. The present paper investigates fishing and environmental variables determining fishing production landed in Manaus and evaluates the relative abundance of commercial fishes in the different sub-systems of the Central Amazon basin. Information collected was used to test the new catch index...
In the outer archipelago of the province of Södermanland in the east of middle Sweden, the remains of fishing camps are frequent. The remains consist of hut ruins, jetties and places where the fishermen dried their nets. The oldest fishing camps of this type are dated to the Viking Age or just before. Although the changes in society during centuries influenced the economic conditions for fishin...
