摘要:

Surveys are described which were made to determine distribution and relative density of stocks of mussels,Perna canaliculusGmelin (Lamellibranchia: Anisomyaria; Mytilidae), in the Firth of Thames, North Island, New Zealand, during the late autumn‐early winter of each year 1961–63 and 1965–67.

摘要:

Surveys made each year between 1962 and 1967 to estimate populations of toheroa(Amphidesma ventricosumGray) on the three main west coast beaches of Northland, New Zealand, are described. The surveys were carried out as close as possible to the beginning and ending of each gathering season. There were striking changes in the surveyed areas, probably mainly due to natural causes and not as a direct result of gathering. One beach, Muriwai 1963, even showed an improvement in population after the gathering season, but numbers of toheroas on this beach have usually been erratic and small during the surveyed period. The other beaches showed marked declines, which were mostly sudden and unsynchronised between beaches; these declines were too big to be accounted for solely by gathering. A private commercial survey, carried out annually during the gathering season on a leased portion of Dargaville Beach, shows very similar results to the equivalent departmental surveys.

摘要:

Three manta rays were seen and photographed in the western Bay of Plenty, New Zealand, in March 1968. Although the species or genus could not be identified, this sighting represents the first substantiated record of the manta ray family (Mobulidae) in New Zealand and confirms the statements of fishermen that, in summer, mantas occasionally appear in offshore game‐fish waters in north‐eastern New Zealand.

摘要:

The ultrasonic signals of dolphins show as “interference noise” on an echo‐sounder record. Some records obtained fromDelphinus delphisin Hauraki Gulf, New Zealand, suggest that these emissions were being used for echo‐ranging, a phenomenon well established by previous work. Possible uses of such records in studying dolphin behaviour are explained.
