| Summary: | Assessing fish performance, whether for extrapolation to natural conditions, culture conditions or toxicology, has a long history of using swim performance, metabolic rates and performance in hypoxia. However, rarely are these metrics unified in a test. Hence, thesis’ objective was to test a respiratory assessment paradigm (RAP), which comprehensively evaluated aerobic and anaerobic metabolism by explicitly measuring aerobic capacity, recovery and performance in hypoxia. To provide high fish throughput with each test, RAP used multiple intermittent-flow respirometry systems. I tested RAP by examining two practical questions: do aquaculture practices compromise the respiratory robustness of domesticated Atlantic salmon (Salmo salar) and, if so, how might it be reversed? Second, does an acute sub-lethal exposure to chemically dispersed oil have a chronic residual respiratory effect on European sea bass (Dicentrarchus labrax). RAP revealed a domesticated (Bolaks) strain of Atlantic salmon had a lower aerobic ... |
