Full description

Monthly sampling of adult Lingula anatina was conducted on the intertidal sand flat at Shelly Beach, near Townsville between February 1973 and February 1974. Gonad indices (100xgonad wet weight/total wet weight) were calculated for 20 female specimens from each sample. Smears of gonad tissue from each animal were made and 20 ova per specimen were measured.Oblique plankton hauls were made at 8 stations along a transect between Townsville and Coil Reef at fortnightly intervals between July 1972 and February 1975. The stations were located at 8, 17, 26, 38, 53, 66, 77 and 86 km from Townsville. Paired nets (mesh size 190 µm and 106 µm, each with a 25 cm aperture) were hauled from the bottom or from a maximum depth of 30 m. Larvae from both nets were treated as a single sample.
