  34. Antarctic krill, Euphausia superba, is hampered by the
  35. lack of data on the metabolic costs associated with
  36. swimming. In this study respiration rates and pleopod
  37. beating rates were measured at six current speeds.
  38. Pleopod beating rates increased linearly with current
  39. speed, reaching a maximum of 6 beats s1 at
  40. 17 cm s1. There was a concomitant linear increase in
  41. respiration rate, from 1.8 mg O2 gD1 h1 at 3 cm s1
  42. to 8.0 mg O2 gD1 h1 at 17 cm s1. The size of the
  43. group tested (50, 100 and 300 krill) did not have a
  44. significant effect on pleopod beating rates or oxygen
  45. consumption (ANCOVA, F=0.264; P>0.05). The
  46. cost of transport reached a maximum of 75 J g1
  47. km1 at 5 cm s1, and then decreased with increasing
  48. current speed to 29 J g1 km1. When considered in
  49. light of energy budgets for E. superba, these data
  50. indicate that the cost of swimming could account for
  51. up to 73% of total daily metabolic expenditure during
  52. early summer." name="eprints.abstract" />

  280. Antarctic krill, Euphausia superba, is hampered by the&#13;
  281. lack of data on the metabolic costs associated with&#13;
  282. swimming. In this study respiration rates and pleopod&#13;
  283. beating rates were measured at six current speeds.&#13;
  284. Pleopod beating rates increased linearly with current&#13;
  285. speed, reaching a maximum of 6 beats s1 at&#13;
  286. 17 cm s1. There was a concomitant linear increase in&#13;
  287. respiration rate, from 1.8 mg O2 gD1 h1 at 3 cm s1&#13;
  288. to 8.0 mg O2 gD1 h1 at 17 cm s1. The size of the&#13;
  289. group tested (50, 100 and 300 krill) did not have a&#13;
  290. significant effect on pleopod beating rates or oxygen&#13;
  291. consumption (ANCOVA, F=0.264; P&gt;0.05). The&#13;
  292. cost of transport reached a maximum of 75 J g1&#13;
  293. km1 at 5 cm s1, and then decreased with increasing&#13;
  294. current speed to 29 J g1 km1. When considered in&#13;
  295. light of energy budgets for E. superba, these data&#13;
  296. indicate that the cost of swimming could account for&#13;
  297. up to 73% of total daily metabolic expenditure during&#13;
  298. early summer.</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">Additional Information:</th><td valign="top" class="ep_row">The original publication is available at www.springerlink.com</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/270603.html">270000 Biological Sciences &gt; 270600 Physiology &gt; 270603 Animal Physiology - Systems</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2053</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 Kerrie Swadling</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">10 Oct 2007 12:59</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=2053;">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=2053">item control page</a></p>
