“…Several observers have associated mass mortalities of adult fishes with abnormally low temperatures (Storey and Gudger 1936, Gunter 1941, Verrill 1901 As far as we know, the present observations are the only ones that have been made which indicate a mortality of marine fish larvae as a result of warming.…”

“…In many habitats, fishes experience marked temperature changes over different time scales. When swimming at different depths, crossing the thermocline (see Glossary) or exposed to diurnal temperature change in tidal pools or other shallow water bodies, the body temperature of fish may acutely change from a few degrees to 20°C over a time scale of minutes to hours (Gunter, 1941;Brill et al, 1999;Nakano and Iwama, 2002;Fangue and Bennett, 2003;Cooke et al, 2008;Caudill et al, 2013;Shiels et al, 2015). Many fishes experience more sustained temperature changes of similar (or greater) magnitude between seasons.…”

The temperature dependence of electrical excitability in fish hearts

Environmental temperature has pervasive effects on the rate of life processes in ectothermic animals. Animal performance is affected by temperature, but there are finite thermal limits for vital body functions, including contraction of the heart. This Review discusses the electrical excitation that initiates and controls the rate and rhythm of fish cardiac contraction and is therefore a central factor in the temperature-dependent modulation of fish cardiac function. The control of cardiac electrical excitability should be sensitive enough to respond to temperature changes but simultaneously robust enough to protect against cardiac arrhythmia; therefore, the thermal resilience and plasticity of electrical excitation are physiological qualities that may affect the ability of fishes to adjust to climate change. Acute changes in temperature alter the frequency of the heartbeat and the duration of atrial and ventricular action potentials (APs). Prolonged exposure to new thermal conditions induces compensatory changes in ion channel expression and function, which usually partially alleviate the direct effects of temperature on cardiac APs and heart rate. The most heat-sensitive molecular components contributing to the electrical excitation of the fish heart seem to be Na + channels, which may set the upper thermal limit for the cardiac excitability by compromising the initiation of the cardiac AP at high temperatures. In cardiac and other excitable cells, the different temperature dependencies of the outward K + current and inward Na + current may compromise electrical excitability at temperature extremes, a hypothesis termed the temperature-dependent depression of electrical excitation.

Beach restoration and construction of port facilities, such as those proposed for Panama City, FL (U. S. Congress, 1972) could affect the organisms inhabiting the nearshore zone (Livingston et al, 1972;May, 1973;Taylor and Saloman, 1968).…”
