The feeding dynamics of males and females of the sequential protandric shrimp Nauticaris marionis were investigated in late austral summer (April) 2002. Results of gut content analysis indicated that N. marionis is an opportunistic feeder preying on a variety of prey, with a preference for detritus, benthic amphipods and gastropods. Overall, pelagic prey made only an insignificant contribution to diet, and was only taken by males. Females of N. marionis exhibited cannibalism, particularly in incubation containers. There was no diel pattern in the feeding activity of N. marionis. In-situ daily rations of males (carapace length <7 mm) and females (>7 mm) were equivalent to ≈10% and ≈5% of body dry weight, respectively. [ABSTRACT FROM AUTHOR] |
