Current research and/or projects

Mr. Knox has been involved in fisheries and aquaculture projects for 27 years and has a broad technical experience in fish enhancement and production, state-of-the-art telemetry and research on fish biology. He has extensive field experience and knowledge of a variety of software and data analyses techniques (especially mapping).

Some highlights of his research include:

  • Shortnose sturgeon project in the Saint John River for the Connecticut Power Commission to determine critical swimming speeds from various live stages of this species and was involved with the first recorded collection of shortnose sturgeon larvae (1979-1980).
  • Various contracts to ID marine and freshwater invertebrates (1980-1985). 
  • Aquaculture research in smolt enhancement, including experiments with transgenic Atlantic salmon (1985-1996, ASF, Connors Bros and DFO).
  • Telemetry tracking of Atlantic salmon smolts in freshwater and post-smolts at sea. Involved in field experiments which helped industry (Vemco Ltd.) develop new technology for underwater telemetry tracking of salmon and other fish species.
  • Chief Scientist on missions using novel methods to live-capture and release Atlantic salmon post-smolts at sea using CCGFV (2000-2004).
  • Collaborated and trained personnel from Fort Folly and Eskasoni First Nations, government, university and NGO’s on deployment and retrieval of underwater telemetry gear.
