Physiological limits of coastal marine species: K.
Gamperl.
This research is investigating the functional relationships between
aerobicity (metabolic scope), maximum cardiac function, heart
morphology, adrenergic capacity (catecholamine
release/adrenoreceptor levels) and immunology in numerous marine
fish species (from mackerel to lumpfish), and examining how various
factors (hypoxia, temperature, domestication, genetic manipulation,
nutritional status) influence the swimming and cardiorespiratory
physiology of cold-ocean fishes. This NSERC, CFI and AquaBounty
Canada supported research is primarily lab based, but technology is
being developed that will permit field studies. The collaborators
are K. Rodnick (Idaho State University), T. Farrell (Simon Fraser),
W. Driedzic, S. McKinley (UBC), and G. Fletcher.
Physiological Aspects of Finfish Culture: K. Gamperl.
The commercial production of cod and haddock in Atlantic Canada is
in its infancy. In cage culture, these species will face
significant seasonal fluctuations in temperature, and temperature
extremes (<0 and ~ 18) which can cause significant physiological
disturbances, reduced growth, and potentially increased mortality.
To help the aquaculture industry minimize and/or ameliorate the
negative effects of these temperature fluctuations and extremes on
cage culture operations, temperature effects on immunology, stress
levels and metabolic physiology will be investigated. This research
is dependent on the OSC’s capacity to rear cod for
experiments at the cage site (Bay d’Espoir, NF), and for
laboratory based research at the OSC. The collaborators are J.
Brown, B. Dixon (Waterloo), D. Barker (Marine Institute), A.
Mansour (DFO), S. Johnson (NRC, Halifax) and S. McKinley (UBC).
