Host = host species sampled, number (N) of individuals sampled in parenthesis; Parasite = Ascaridoid species identified, number (N) of parasites found in parenthesis; Muscle = infection data for the muscle; Viscera = infection data for the viscera; Total = infection data in viscera and muscle; P = prevalence of infection as percentage; mA = mean abundance, standard deviation in parenthesis; mI = mean intensity, standard deviation in parenthesis and range (minimum – maximum number of parasites in the sample) with curly brackets. * Just the belly flaps (i. e. anterior-ventral portion of the fillets) were examined in these fishes.
