  32. <meta content="Aseasonal catchability model for the rock lobster Jasus edwardsii, which had been developed previously for a population in a
  33. scientific reserve,was applied to catchability estimates over several years in northern and southern fishing regions off Tasmania,
  34. Australia. Catchability was estimated from commercial catch and effort data and fishery-independent estimates of exploitation
  35. rates. The seasonal catchability models describe the effects of water temperature, moulting and mating on catchability. They
  36. suggest that similar environmental and physiological processes underpin seasonal catchability in the two regions of the
  37. fishery, but that the relative importance of these factors varies considerably between the two regions. Physiological processes
  38. dominate the pattern of catchability in the north while water temperature contributes significantly to the model only in the
  39. south. Interannual variation in relative catchability was correlated with density-dependent processes. Full models described

  317. scientific reserve,was applied to catchability estimates over several years in northern and southern fishing regions off Tasmania,&#13;
  318. Australia. Catchability was estimated from commercial catch and effort data and fishery-independent estimates of exploitation&#13;
  319. rates. The seasonal catchability models describe the effects of water temperature, moulting and mating on catchability. They&#13;
  320. suggest that similar environmental and physiological processes underpin seasonal catchability in the two regions of the&#13;
  321. fishery, but that the relative importance of these factors varies considerably between the two regions. Physiological processes&#13;
  322. dominate the pattern of catchability in the north while water temperature contributes significantly to the model only in the&#13;
  323. south. Interannual variation in relative catchability was correlated with density-dependent processes. Full models described&#13;
  324. 72% of the total variation in catchability over 6 years in the south and 80% of the total variation over 4 years in the north.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">Definitive version is available online at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Jasus edwardsii; Rock lobster; Catchability; Water temperature; Moulting; Density&#13;
