Shrimp are the most economically valuable internationally-traded seafood commodity, and wild-caught, trawled shrimp make up almost half of the ~6.6 million metric tons of annual global production. Shrimp trawling is responsible for one-third of the world’s total fisheries bycatch, leading many to consider shrimp trawling to be the single most destructive fishing practice in the world. Though the bycatch of large marine animals can be significantly reduced by use of turtle excluder devices (TEDs)...

Atlantic bluefin tuna Thunnus thynnus (ABFT) support commercial and recreational fisheries throughout the North Atlantic Ocean. Due to heavy fishing pressure over the course of several decades, the eastern and western stocks of ABFT were overfished and the current biomass of the western stock is estimated to be approximately 19% of the biomass necessary for maximum sustainable yield. Despite a variety of management measures, including the implementation of minimum sizes and reductions of the tot...

Community concerns regarding natural resource management may be addressed in several forms. The community may participate as part of the public in the management process; community concerns may be included in social impact assessment; and communities may directly participate as managers of resources whether on their own or in conjunction with higher levels of government. In fisheries, typically community concerns are addressed through social impact assessment which is perceived to be lacking in ...

Goldsmith, William Morris

Atlantic bluefin tuna (Thunnus thynnus) are targeted by recreational anglers along the east coast of the United States, and the fishery is thought to be of considerable economic value. However, limited knowledge of the preferences and values of fishery participants impedes the ability of managers to maximize fishery benefits and predict harvest patterns, while an incomplete understanding of post-release mortality hinders efforts to estimate total mortality resulting from the fishery. This disser...

Many production activities typically produce undesirable outputs, e.g., the production of the pollutant sulfur dioxide in the generation of electricity. Traditional economic metrics may overstate the efficiency and productivity of these production activities by failing to account for the undesirable outputs. These omissions can lead to conclusions that are biased against resource conservation and protection. Many fisheries capture their target species concomitantly with undesirable outputs such ...

The economic value (as measured by consumer's surplus) and the economic impact (as measured by sales, employment and wages and salaries) were estimated for Florida's east and west coast recreational and commercial king mackerel fisheries using 1986 data. In 1986, the king mackerel fisheries in Florida were economically more important to both the nation (using consumer's surplus) and to the state of Florida's economy (using sales, employment and wages salaries impact) than the commercial king mac...

Conventional fisheries management approaches have been shown, in many instances, to have been ineffective in dealing with complex conservation concerns such as bycatch. Greater considerations for broader-scale and holistic approaches, as proposed by the 'Ecosystem Approach to Fisheries' (EAF) and the 'balanced harvesting approach', are beginning to challenge some of the negative misconceptions around bycatch, especially in small-scale fisheries. The need for a more holistic approach to fisheries...

Clam populations globally have declined, or been depleted, with one of the major causes being uncontrolled human exploitation. This thesis investigates the population structure, growth, reproduction and exploitation of the beaked clam Eumarcia paupercula in Maputo Bay. The substantial commercial harvesting of this clam may lead to overexploitation of the resource. In this regard, some fundamental knowledge is necessary for the management of future exploitation. The data collection was based on a...

<p> Size-at-age of Pacific Halibut (<i>Hippoglossus stenolepis</i>) has declined significantly since the 1980s. For instance, the average weight of a 20-year-old female declined from 55 kg in 1988 to 20 kg in 2014. The decline in size-at-age corresponds to a period of declining Pacific Halibut recruitment, spawning biomass, and reductions in catch limits for the directed commercial Pacific Halibut longline fishery. The causes of changes in Pacific Halibut size-at-age are poorly understood. Our p...

Cumulative stressors influence the infection development, health and survival of wild Pacific salmon (Oncorhynchus spp.). Infectious disease is generally assumed to be the ultimate cause of death of wild adult salmon, but empirical evidence demonstrating links between infections and early mortality (i.e., prior to spawning) is lacking, especially as a function of cumulative migratory stressors. The influences of high river temperature and fishery capture and release on infection development and ...

The FAO global statistics on fisheries catches is an important tool used to track overall patterns, as it represents the only global account of fisheries catch records from all member countries. However, the database is only as complete as the data sent to them by member countries, which often lack catch amounts from non-commercialized sectors. The aim here for Chapters 2 and 3 were to comprehensively account for total fisheries removals for Turkey and Cyprus from 1950-2010, by estimating catc...
