Spatial-Temporal Distribution of a Commercial Fishery: A Geostatistical Approach to Efficiency and Sustainability
The spatial and temporal distribution of yellowtail flounder catch rate on the Grand Banks of Newfoundland was studied in order to see patterns concerning "where" and "when" in this fishery. Spatial analysis asks the question "Where are they fishing?" and examines relationships between catch and environmental variables (bathymetry, sea state, sediment type, and water temperature). Temporal analysis asks the question "When are they fishing?" in order to observe differences in catch rate between day, night and seasons. By answering these questions we have determined quantifiable patterns in an industry's fishing practices. In doing so we hope to find ways industry can act more efficiently and sustainably.
