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...
Aquaculture ranks among the most dynamic food production industries in the world, with an annual growth rate of 9.2% since 1970 [1]. Both the fisheries and aquaculture sectors are facing strengthened regulations, with an emphasis on improving sustainable growth and environmental protection. The New Earth Observation Markets for Fisheries and Aquaculture (NEMA) project has established a number o...
If approved by the Secretary, proposed Amendment 108 to the BSAI FMP, proposed Amendment 100 to the GOA FMP, and proposed Amendment 46 to the Crab FMP would correct the omissions in each FMP by adding ‘‘or equal to’’ to the length limits. Specifically, these FMP amendments would add vessels 26 ft (7.9 m) LOA in the GOA and vessels 32 ft (9.8 m) LOA in the BSAI, including BSAI Crab, to the LLP e...
Non-compliance with fishing regulations by Iranian fishermen in three provinces of Khuzestan, Bushehr, and Hormozgan along the Persian Gulf was investigated. Using a questionnaire and a stratified random sample method, a total of 566 fishermen were interviewed. The legitimacy variables (outcome and process) that can explain the observed noncompliance with zoning regulations for the shrimp fishe...
Modern fishery science, which began in 1957 with Beverton and Holt, is ca. 50 years old. At its inception, fishery science was limited by a nineteenth century mechanistic worldview and by computational technology; thus, the relatively simple equations of population ecology became the fundamental ecological science underlying fisheries. The time has come for this to change and for community ecol...
Climate change is already producing ecological, social, and economic impacts on fisheries, and these effects are expected to increase in frequency and magnitude in the future. Fisheries governance and regulations can alter socio-ecological resilience to climate change impacts via harvest control rules and incentives driving fisher behavior, yet there are no syntheses or conceptual frameworks fo...
Traditional fisheries management theory supports aggressive exploitation of old and large fish to maximize a stock’s biomass production and yield. Here we present an age-structured fish population model with multidimensional density-dependence to test the hypotheses that protection of large, fecund individuals is beneficial for the population and selected fisheries variables and that effects of...
—The fisheries literature embodies critical assumptions about fisherman attitudes and motivations. Common assumptions are that populations of fishermen are homogeneous in motivation and decision making and that they behave in a myopic fashion, ignoring the effects of their fishing activities on the fishery resource. The results of a survey of trawl vessel captains challenge these assumptions. W...
