Fish ExaminationThe Centre for Aquaculture and Seafood Development and the Ocean Sciences Centre have a proven track record in the field of fish and shellfish health. Past and on-going research and development projects include:

Commercialization of Atlantic Cod

  • Funded by Atlantic Canada Opportunities Agency through the Atlantic Innovation Fund, this project examines broodstock selection, larval production, weaning and juvenile growth, stocking density, cage site husbandry, fish health, flesh quality, and marketing.  

Cod Genomics Project (CGP)

  • Funded through Genome Atlantic, this project involves the development of a breeding program and a set of fundamental genomics tools used to supply the developing Atlantic cod aquaculture industry in Canada with improved broodstock. 

Salmonid Broodstock Program

  • The application of transgenic technology as a means of enhancing desirable commercial broodstock traits of salmonids was pioneered by researchers at Memorial University. Efforts are ongoing to evaluate the performance of different life stages of Atlantic salmon modified for enhanced growth. The project is supported by Aqua Bounty Canada Inc., a subsidiary of Aqua Bounty Technologies.

Atlantic Cod Broodstock Program/Selective Breeding in Atlantic Cod

  • A joint initiative of Department of Fisheries and Oceans, industry and Memorial University, this project is aimed at improving cod broodstock husbandry practices and investigating paired mating protocols for captive broodstock.

Research Cage Site

  • Research has focused on lipid and protein analyses for egg quality criteria, live food enrichment diets, first feeding/starter diets and juvenile grow-out diets for halibut, wolffish and other marine species, marine systems design, water quality and behaviour studies.

Large-scale Disposal of Aquaculture Waste Products

A joint initiative of the Newfoundland Aquaculture Industry Association and Memorial University, this study identified the technology requirements to promote environmentally progressive methods of dealing with waste disposal and/or treatment.

  • Particular emphasis was given to the following:
  • Disposal of fish biomass resulting from sudden or unexpected large-scale mortalities
  • Disposal of diseased or contaminated fish biomass (e.g. ISA, Nodavirus, etc.)
  • Disposal of finfish and shellfish biomass resulting from processing waste, equipment damage, or government order for removal
  • Disposal of waste products resulting from the cleaning of nets, in particular the copper contaminated biofoulants

Fish and Shellfish Health Studies

  • Numerous fish and shellfish health studies have been undertaken, including:
    • Evaluation of oral immunostimulant efficacy Evaluation of microsporidian infections
    • Infectious diseases of wild and captive gadoids in Atlantic Canada
    • Modeling of marine biofouling organisms
  • Baseline surveys of parasites and pathogens in Newfoundland mussels
  • Biochemical assays for health assessment in scallops, mussels, oysters, and the marine environment.
