  27. <meta content="Wild-caught blacklip (Haliotis rubra) and greenlip (H. laevigata) abalone were held
  28. from spent condition at 12 degrees C, 14 degrees C, 16 degrees C or 18 degrees C and routinely sampled to examine gonad
  29. development. Descriptors of gross structure included the Visual Gonad Index (VGI) and
  30. the Modified Gonad Bulk Index (MGBI). Oocyte Diameter Ratio (ODR) and oocyte
  31. volume (based on an ellipsoid) were used as descriptors of ovarian microstructure. For
  32. each species, the rate of increase in the VGI, MGBI and oocyte volume of animals held at
  33. different temperatures were used to estimate the Biological Zero Point (BZP), the critical
  34. temperature below which no development occurs. BZP estimates derived from the daily
  35. increase in VGI and oocyte volume were similar (7.8 degrees C and 7.6 degrees C for blacklip abalone;
  36. 6.9 degrees C and 6.8 degrees C for greenlip abalone, respectively), but those based on the increase in
  37. MGBI were up to 1.8 degrees C lower (6.0 degrees C and 5.7 degrees C, for blacklip and greenlip abalone,
  38. respectively). The mean MGBI, in terms of gonad volume per gram of shucked animal
  39. weight, ranged from 5-68 mm3g-1 and 5-58 mm3g-1 for blacklip and greenlip abalone,
  40. respectively. The ODR indicated that oocyte shape was highly variable in oocytes < 90 um
  41. diameter in both species. Above 90 um, ODR values increased proportionally with oocyte
  42. size, indicating a transition in shape from elliptical to round. Ranges for mean oocyte
  43. volume for blacklip and greenlip abalone were 0.15-1.4 x 106 um3 and 0.02-1.83 x 106
  44. um3, respectively. The pattern of oocyte growth relative to temperature for both species is
  45. illustrated using tables of standardized residuals. Determination of the BZP for blacklip
  46. and greenlip abalone enables the calculation of the Effective Accumulative Temperature
  47. EAT; the cumulative difference between the water temperature and the BZP, calculated
  48. daily) for gamete maturation of these species. This in turn facilitates predictive and
  49. deductive estimates of the completion of this process (when water temperature is known)

  234. from spent condition at 12 degrees C, 14 degrees C, 16 degrees C or 18 degrees C and routinely sampled to examine gonad
  235. development. Descriptors of gross structure included the Visual Gonad Index (VGI) and
  236. the Modified Gonad Bulk Index (MGBI). Oocyte Diameter Ratio (ODR) and oocyte
  237. volume (based on an ellipsoid) were used as descriptors of ovarian microstructure. For
  238. each species, the rate of increase in the VGI, MGBI and oocyte volume of animals held at
  239. different temperatures were used to estimate the Biological Zero Point (BZP), the critical
  240. temperature below which no development occurs. BZP estimates derived from the daily
  241. increase in VGI and oocyte volume were similar (7.8 degrees C and 7.6 degrees C for blacklip abalone;
  242. 6.9 degrees C and 6.8 degrees C for greenlip abalone, respectively), but those based on the increase in
  243. MGBI were up to 1.8 degrees C lower (6.0 degrees C and 5.7 degrees C, for blacklip and greenlip abalone,
  244. respectively). The mean MGBI, in terms of gonad volume per gram of shucked animal
  245. weight, ranged from 5-68 mm3g-1 and 5-58 mm3g-1 for blacklip and greenlip abalone,
  246. respectively. The ODR indicated that oocyte shape was highly variable in oocytes &lt; 90 um
  247. diameter in both species. Above 90 um, ODR values increased proportionally with oocyte
  248. size, indicating a transition in shape from elliptical to round. Ranges for mean oocyte
  249. volume for blacklip and greenlip abalone were 0.15-1.4 x 106 um3 and 0.02-1.83 x 106
  250. um3, respectively. The pattern of oocyte growth relative to temperature for both species is
  251. illustrated using tables of standardized residuals. Determination of the BZP for blacklip
  252. and greenlip abalone enables the calculation of the Effective Accumulative Temperature
  253. EAT; the cumulative difference between the water temperature and the BZP, calculated
  254. daily) for gamete maturation of these species. This in turn facilitates predictive and
  255. deductive estimates of the completion of this process (when water temperature is known)
  256. in either natural or artificial (i.e. culture) environments.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><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">Keywords:</th><td valign="top" class="ep_row">Biological zero point; Haliotis laevigata; Haliotis rubra; Modified gonad bulk index; Oocyte morphometrics; Temperature; Visual gonad index</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/300701.html">300000 Agricultural, Veterinary and Environmental Sciences &gt; 300700 Fisheries Sciences &gt; 300701 Physiology and Genetics</a><br /><a href="http://eprints.utas.edu.au/view/subjects/300703.html">300000 Agricultural, Veterinary and Environmental Sciences &gt; 300700 Fisheries Sciences &gt; 300703 Aquaculture</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1530</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Dr Arthur J Ritar</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">20 Aug 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1530;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=1530">item control page</a></p>
