Article
During stock assessment, fishery-dependent observations are often used to develop indices of abundance or biomass from catch per unit of effort (CPUE) and contribute catch at size or age information. However, fisher behavior, rather than scientific sampling protocols, determines the spatial and temporal locations of fishery-dependent observations....
Article
With wild-capture fisheries, important globally as a source of food and livelihood, and facing chronic overfishing, development of the best available science can reduce scientific uncertainty and improve the quality of science-based advice and the credibility to stakeholders of the management decisions based on that science. Fish stock assessments...
Article
As global fisheries management shifts towards ecosystem-based management, responsible organizations and governments must also address the socio-economic impacts of this shift. This study evaluates potential impacts of such management shift with a case study of Pulley Ridge (PR), an ecologically rich area in the Gulf of Mexico, on fishermen and econ...

For the first time, the age and growth of the longbill spearfish, Tetrapturus pfluegeri Robins and De Sylva, 1963, was estimated using transverse sections from the third spine of the anal fin. The samples used were collected in a large zone of the western Atlantic Ocean between 22°N and 36°S, from the artisanal gillnet and commercial longline fleet...
Article
When, where, and how a commercial vessel fishes determines the temporal and spatial placement of the data they are legally bound to supply to management agencies. Data provided by commercial fishing vessels are used in assessments to infer fish population abundance. Fisher decision-making may also allow fishers to dissipate the benefits of regulati...
Article
Exploited marine fish populations are known to exhibit complex spatial dynamics and display age-structured processes, yet many models of these populations do not account for within-population variability in age in conjunction with the spatial distribution of individuals within a stock management area. Our work presents a method of modeling, known a...
Conference Paper
Electronic tags have enabled scientists to describe fish movements, habitat usage and migration patterns. However, the high cost of these tags limits the number that can be deployed. We consider what could be done if technological improvements and the production of tags with fewer features allowed large numbers of smaller tags with longer battery l...

Large pelagic fish resources, such as tuna and wahoo, are usually migratory and fish stocks are often not limited to specific sea areas such as the Caribbean Large Marine Ecosystem (CLME), but are shared with, and utilized by, an extended stakeholder community. Implementing an Ecosystem Approach to Fisheries (EAF) for these resources therefore requ...
Conference Paper
In order to understand the effect of fishing on fish populations, it is necessary to not only study the population dynamics of the fish, but also the population dynamics of the fishers themselves. A spatially explicit individual-based model of the West Florida Shelf in the Gulf of Mexico is presented which tests the performance of estimation method...

Full-text available
The size-frequency distribution of the commercial catch is often used as the basis of fisheries stock assessments (Paul and Morgan, 1987; Gulland and Rosenberg, 1992) because most dynamic processes of populations (growth, survival, recruitment) are reflected in changes in this distribution. The data are generally collected, often at great expense,...
