N2  - A comment on &#8216;Spawning dynamics of the eastern gemfish (Rexea solandri) in relation to regional oceanography in south-eastern Australia&#8217; by J. D. Prince and D. A. Griffin, Marine and Freshwater Research 52, 611&#8211;22. Temporal trends through the winter seasons in commercial landings of eastern gemfish (Rexea solandri) during the years 1977&#8211;79, 1982&#8211;85, 1986&#8211;87 and 1989&#8211;92 were reasonably stable for given latitudes, despite variable oceanographic influences, as depicted by 250 m isotherm data. This suggests that the overall pattern of occurrence of pre-spawning aggregations of eastern gemfish in these periods was determined by a combination of time of the season and latitude, rather than by oceanographic factors. Between 1986 and 1996, only four instances were identified where gemfish catches contained &#62;10%of &#8216;running ripe&#8217; females, and the variety of oceanographic conditions under which these catches were made provides little support for the hypothesis that eastern gemfish spawn into subsurface plumes of upwelled sub-Antarctic water.
