Abstract(s)

Changes in water temperature may have profound effects on phy-siology, metabolism, and fish behaviour. However, much of theexisting research is based on relatively short-term experiments. Inthe context of climate change, where water temperatures areincreasing seasonally, and the frequency and duration of extremeheatwave events are rising, incorporating longer exposure periodswill provide a better understanding of the potential effects ofwarming on marine species. Here, we tested the effects of pro-longed exposure to elevated temperature on broad-nosed pipefish,Syngnathus typhle. Fish were exposed to ambient (20ºC) and high(24ºC) temperatures for a four-month period, during which activitylevels, growth and survival were monitored. Fish under high tem-perature were less active when compared to fish under ambienttemperature, grew less, and survival was dramatically decreased.These findings have significant implications for the long-term sus-tainability of broad-nosed pipefish populations, as the species maystruggle to adapt to future ocean conditions.
