June 3, 2018 — New computer-generated daily maps will help fishermen locate the most productive fishing spots in near real time while warning them where they face the greatest risk of entangling sea turtles, marine mammals, and other protected species. Scientists developed the maps, the products of a system called EcoCast, to help reduce accidental catches of protected species in fishing nets.
Funded primarily by NASA with support from NOAA, California Sea Grant, and Stanford University, EcoCast was developed by NOAA Fisheries scientists and academic partners with input from fishermen and managers.
Using the swordfish fishery as an example, EcoCast incorporates data from tagged animals, remote sensing satellites, and fisheries observers to help predict concentrations of target species (broadbill swordfish) and three protected species (leatherback turtle, blue shark and California sea lion).
EcoCast will help fishermen, managers, scientists, and others understand in near real-time where fishing vessels have the highest probability of catching targeted species and where there is risk of catching protected species. In doing so, EcoCast aims to improve the economic and environmental sustainability of fisheries that sometimes inadvertently catch and kill sensitive species.
