Fisheries Software Online
The most widely used software package for the development of state-of-the-art fisheries stock assessment methods, Automatic Differentiation Model Builder, or ADMB, can now be downloaded without charge from a public website. The website was created through efforts by Manoa’s Pelagic Fisheries Research Program in partnership with NOAA Fisheries and the National Center for Ecological Analysis and Synthesis.
ADMB-based computer models are used globally to monitor populations of many endangered and commercially valuable species, to develop place-based resource management policies, and to reconstruct movements of animals tracked with electronic tags. ADMB-based stock assessments are critical to the management of commercially important fisheries stocks worth billions of dollars as well as ecologically sensitive species, in the United States and internationally.
ADMB has proven to be an essential tool for a wide range of statistical analysis, especially in fisheries stock assessments. With its recent emergence as free software, it is likely that ADMB will find application to a growing number of challenges in ecological modeling.
“Thanks to ADMB, it is no longer necessary to omit or transform data because they do not meet the arbitrary assumptions of some ‘canned’ software package,” says Program Manager John Sibert. “Instead, it is possible to include a diversity of data in statistical models. This power has revolutionized modeling of natural resources.”
