Pacific spiny dogfish (Squalus suckleyi) thermal tolerance

Datasets are presented for analyses in Bouyoucos et al. (In Prep). See the 'metadata' text file for descriptions of individual .csv files and descriptions of column headings. Experiments on male Pacific spiny dogfish (Squalus suckleyi) were approved by the Bamfield Marine Sciences Centre (BMSC) Animal Care Committee (animal user protocol RS-22-10). Male dogfish were collected using rod-and-reel and demersal longline in Barkley Sound (British Columbia, Canada) under the approval of Fisheries and Oceans Canada permit XR-199 2022. This dataset supported a study that tested the hypothesis that behavioural responses to acute temperature increase are associated with cardiorespiratory thermal tolerance and thermal cellular stress. Dogfish were first tested for cardiorespiratory and behavioural thermal limits to test for associations between thermal performance and tolerance. Then, biochemical markers of secondary stress, aerobic and anaerobic enzyme activities, and molecular markers of cellular stress were determined for various tissues at the agitation temperature, and secondary stress markers were determined at the critical thermal maximum. These data provide new information on putative physiological mechanisms underpinning the agitation temperature and expand knowledge on thermal tolerance in elasmobranchs.
