Abstract:

Schwartz reports on eight species of stingrays collected by trawl and longline between 1972-2010 at two Onslow Bay sites. Three species were collected more often during a cooler water period and five others during a warmer water period. He summarizes the recent status of the stingrays noting sizes, seasonality of occurrence, sex ratios, and batch changes during the sampling period.
