The French Institute for the Exploitation of the Sea (Ifremer) has designed an open software suite for storing fisheries acoustic data and computing acoustic indicators for survey-based ecosystem monitoring. It comprises a postgreSQL database designed to store acoustic, navigation and fishing data from ecosystemic surveys (EchoBase) and a suite of R codes (EchoR) for computing fish population indicators based on Echobase data. This site describes the Echobase database. If you are interested in EchoR, please visit the Ifremer forge.

EchoBase is built upon an open source PostgreSQL database, ensuring large storage capacities and easy integration into Geographical Information Systems or dynamic websites. It has been designed to store data collected during both acoustic and bottom trawl based ecosystemic cruises. The EchoBase data model is based on the ICES WGFAST Topic Group on metadata standards recommendations. It comprised a main « cruise metadata branch » on which are plugged acoustic and fishing (« Operation ») data. Biomass estimation results can also be stored in the database at both the acoustic cell (small scale results) and voyage (large scale results)levels. The database also allows for the storage of length-weight and Target Strength-length reference relationships, as well as map data at the voyage level.

EchoBase features a Java web-browser interface for selecting working databases, managing users, importing, editing and querying data. It also can be easily connected to LibreOffice base, the R statistical software or Geographic Information Systems such as QuantumGIS for querying and mapping data. Portable H2 databases can be extracted from the server-based EchoBase instance and stored on a local harddrive.
