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

Antarctic krill, Euphausia superba, is hampered by the
lack of data on the metabolic costs associated with
swimming. In this study respiration rates and pleopod
beating rates were measured at six current speeds.
Pleopod beating rates increased linearly with current
speed, reaching a maximum of 6 beats s1 at
17 cm s1. There was a concomitant linear increase in
respiration rate, from 1.8 mg O2 gD1 h1 at 3 cm s1
to 8.0 mg O2 gD1 h1 at 17 cm s1. The size of the
group tested (50, 100 and 300 krill) did not have a
significant effect on pleopod beating rates or oxygen
consumption (ANCOVA, F=0.264; P>0.05). The
cost of transport reached a maximum of 75 J g1
km1 at 5 cm s1, and then decreased with increasing
current speed to 29 J g1 km1. When considered in
light of energy budgets for E. superba, these data
indicate that the cost of swimming could account for
up to 73% of total daily metabolic expenditure during
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 > 270600 Physiology > 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&eprintid=2053">item control page</a></p>
