Abstract
Application of Remote Sensing and GIS to Identifying Marine Fisheries off the Coasts of Kenya and Tanzania
Highlights
A thorough understanding of key environmental parameters and their influence on pelagic fish distribution can inform exploration for prospective fishing zones
There is a need for more effective methods that can capture changes instantaneously over broad regions
The fishers were required to switch on their GPS units every time they went out fishing and to record a point each time they caught fish
Summary
A thorough understanding of key environmental parameters and their influence on pelagic fish distribution can inform exploration for prospective fishing zones. Sea surface temperature (SST) is a significant physical factor that strongly influences the physiology and growth of ocean life, including phytoplankton and all other organisms at higher trophic levels (Tang et al, 2003), and can be used to help identify fishing grounds. Collecting measurements of oceanographic parameters from boats over large areas is time consuming and expensive and can be impractical for identifying commercially viable fishing areas due to the dynamic nature of the ocean.
