ECHOBASE—A portable geographic fishery research database system

摘要: A geographic fishery research database system (GFRDBS), called ECHOBASE, for storing and management of data on pelagic fish resources from acoustic surveys catch samples, combined with environmental in a context, has been developed. The constitutes portable inexpensive yet powerful tool monitoring provides on‐board processing mapping capabilities. Data are acquired an echosounder, echo signal processor, profiler (CTD probe), Global Positioning System (GPS) receiver. electronic digitized maps (based C‐MAP public format files) provide active on‐screen nautical charts. basic GFRDBS platform is PC 486 machine, which used as acquisition running under MS Windows 3.1 operating environment. designed around the Borland's PARADOX package, relational managing acoustic, catch, data.
