GIS methods for inventory of pacific salmons spawning grounds in the Amur River

Abstract

 Inventory of spawning grounds is an important tool for estimation of pacific salmons abundance and adequate management of their stocks. A set of the most up-to-date, relevant and effective methods based upon geographic information system (GIS) is substantiated, designed, developed and scheduled to implementation for inventory of the spawning grounds in the Amur basin. Abilities of GIS-technologies for optimization of the surveys planning and conducting and for processing, analysis, visualization and presentation of their results due to accelerated, simplified and enhanced workflow are shown. Three components of modern corporative GIS are presented: server, desktop and mobile ones. The system is partially loaded with the data about spawning grounds, tested for the basic operations as data collection, multi-user editing, geoprocessing, spatial analysis, cartographic visualization, protected web publication, etc., and adjusted and improved using the results of this testing for further implementation in complex fisheries surveys in the Amur River basin. Proposed GIS-technology is modifiable and scalable, so can be spread to other species and areas after appropriate modification; the GIS can be specialized for certain practical tasks.
