Gary Melvin

Research Scientist
Fisheries and Oceans Canada

Current research and/or projects

Dr. Melvin is an experienced and internationally recognized scientist with more than 25 years of expertise in fisheries research, stock assessment and hydroacoustics. His research has been broad in scope and multi-species in application. He has had substantial influence on the development of the SABS herring and acoustic programs. He has also developed a strong working relationship with external clients, especially the fishing industry.

Over the years he has been responsible for the implementation of several major DFO/industry collaborative initiatives. He has extensive experience working with non-salmonid anadromous fishes, scallops, herring and orange roughy, and has lead the acoustic program at SABS for the past 10 years.

Some highlights of his research include:

  • Implementation of a multi-national research project to assess the status of hilsa in the Ganges (Bramapotria) River in Bangladesh.
  • Major contribution to the Environmental Impact Assessment for the NB/PEI Fixed Link.
  • Assessment and Research on the recovery Georges Bank herring that led to the reopening of the fishery in the mid-1990. This stock of herring collapsed around 1978 and spawning on the Canadian portion of the bank was not documented until 1992.
  • Project leader for the multi-beam sonar component of the National Hydroacoustic Program. Dr Melvin and collages developed the mathematical framework and the technical methods for calibrating these complex systems. They also made significant advances in the area of 3D visualization of multi-beam sonar data.
  • Development and implementation of acoustic surveys using commercial fishing vessels. These data now form a key index of abundance in accessing the 4WX herring stock status.

Dr. Melvin took a two year leave of absence (2004-2005) to work with the Science Branch of New Zealand Seafood Industry Council in Wellington as a stock assessment scientist. His responsibilities included scientific advisor to the fishing industry, in stock assessments, research planning and survey/sampling project development.
