Abstract
A prey species of fish ( Dascyllus aruanus) was envenomated with venom fractions of Aipysurus laevis. Fraction group ventilation profiles were compared to a model of ventilation changes possessing three divisions for a medium venom dose to examine differences in fraction profiles with whole venom. All groups, including controls, showed an increase in ventilation in division 1 due to subject manipulation. Fractions 1, 3, 5, 6 and a fraction recombination showed significant increases in ventilation rates from the control in division 2. Fractions 2 and 4 were shown to be significantly lower in ventilation rates during this division. Fractions 1, 3, 5 and 6 are suspected of having neurotoxic characteristics with fraction 6 being the major neurotoxin in A. laevis venom. Significant differences were seen between the experimental group ventilation profiles.
