Modeling And Simulation Of American Lobster In The Gulf Of Maine: Spatial Distribution, Monitoring, And Conservation, Bai Li
Electronic Theses and Dissertations
In spite of the high fishing pressure and landings, the Gulf of Maine (GOM) American lobster (Homarus americanus) population abundance has increased dramatically since the early 1990s. Various hypotheses have been developed to explain such an increase, ranging from improved habitat to conservation measures that protect female spawners. However, no systematic study has been done to evaluate these hypotheses. This study aims to examine roles of environmental drivers and conservation measures in regulating the dynamics of lobster population, and evaluate the performance of monitoring programs. A geographical weighted regression model was developed to examine the non-stationary environmental effects …

Incorporating Environmental Variability Into Assessment And Management Of American Lobster (Homarus Americanus), Kisei Tanaka
Electronic Theses and Dissertations
The American lobster (Homarus americanus) support one of the most valuable fisheries in the United States. A growing body of literature recognizes the importance of environmental variables in regulating this species’ biogeography and population dynamics. However, the current lobster stock assessment and management do not explicitly consider the impact of environmental variables such as water temperature and assumes spatiotemporal variabilities in the lobster environment as random background noises. Furthermore, while climate-induced changes in marine ecosystems continue to impact the productivity of lobster fisheries, studies that model lobster response to altered environmental conditions associated with climate change are lacking. …
