Dual frequency identification SONAR (DIBSON) facility for sampling benthic and pelagic fish populations

Grant


Scheme


  • Linkage Infrastructure Equipment & Facilities (LIEF)

Abstract


  • The Sydney Basin has one of Australiaâ¬"s largest communities of temperate fish ecologists and we have a common problem: the census of fish populations in low visibility environments such as in rivers, estuaries and ports. Current approaches for sampling fish populations involve capturing fish with nets, or recording them by underwater video or diver surveys. The DIDSON produces near video quality images of benthic and pelagic fish using sound waves rather than light, overcoming many limitations of standard sampling techniques. This facility represents a novel application of the DIDSON to study fish biology and fisheries, and will provide a cost-effective and uniform method for observing fish in difficult or dangerously turbid environments.
