"Potassium chloride (KCl: 330 mg/ml) was assessed as an
euthanasia agent in American lobsters (Homarus americanus). Two
groups of 10 lobsters (408.2 to 849.9 g) were maintained at 11.9
to 12.1 °C ('warm') and 1.5 to 2.5 °C ('cold') to evaluate the
possible effect of ambient temperature on response to KCl. Death
was defined as time of cardiac arrest, as viewed and measured by
use of ultrasound. The KCl solution was injected (100 mg of
KCl/100 g of body weight) at the base of the second walking leg
to flood the hemolymph sinus containing the ventral nerve cord
with potassium. Disruption of this 'central nervous system' was
immediate, followed by car
