<meta content="Growth of a temperate reefassociated
fish, the purple wrasse (Notolabrus
fucicola), was examined
from two sites on the east coast of
Tasmania by using age- and lengthbased
models. Models based on the
von Bertalanffy growth function, in
the standard and a reparameterized
form, were constructed by using otolith-
derived age estimates. Growth
trajectories from tag-recaptures were
used to construct length-based growth
models derived from the GROTAG
model, in turn a reparameterization
of the Fabens model. Likelihood
ratio tests (LRTs) determined
the optimal parameterization of the
GROTAG model, including estimators
of individual growth variability,
seasonal growth, measurement error,
and outliers for each data set. Growth
models and parameter estimates were
compared by bootstrap conf idence
intervals, LRTs, and randomization
tests and plots of bootstrap parameter
estimates. The relative merit of
these methods for comparing models
a nd pa ramet ers was eva luat ed ;
LRTs combined with bootstrapping
and randomization tests provided
the most insight into the relationships
between parameter estimates.
Significant differences in growth of
purple wrasse were found between
sites in both length- and age-based
models. A significant difference in
the peak growth season was found
between sites, and a large difference
in growth rate between sexes
was found at one site with the use
of length-based models." name="eprints.abstract" />

fish, the purple wrasse (Notolabrus
fucicola), was examined
from two sites on the east coast of
Tasmania by using age- and lengthbased
models. Models based on the
von Bertalanffy growth function, in
the standard and a reparameterized
form, were constructed by using otolith-
derived age estimates. Growth
trajectories from tag-recaptures were
used to construct length-based growth
models derived from the GROTAG
model, in turn a reparameterization
of the Fabens model. Likelihood
ratio tests (LRTs) determined
the optimal parameterization of the
GROTAG model, including estimators
of individual growth variability,
seasonal growth, measurement error,
and outliers for each data set. Growth
models and parameter estimates were
compared by bootstrap conf idence
intervals, LRTs, and randomization
tests and plots of bootstrap parameter
estimates. The relative merit of
these methods for comparing models
a nd pa ramet ers was eva luat ed ;
LRTs combined with bootstrapping
and randomization tests provided
the most insight into the relationships
between parameter estimates.
Significant differences in growth of
purple wrasse were found between
sites in both length- and age-based
models. A significant difference in
the peak growth season was found
between sites, and a large difference
in growth rate between sexes
was found at one site with the use
of length-based models.</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">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/300700.html">300000 Agricultural, Veterinary and Environmental Sciences > 300700 Fisheries Sciences</a><br /><a href="http://eprints.utas.edu.au/view/subjects/300000.html">300000 Agricultural, Veterinary and Environmental Sciences</a><br /><a href="http://eprints.utas.edu.au/view/subjects/300703.html">300000 Agricultural, Veterinary and Environmental Sciences > 300700 Fisheries Sciences > 300703 Aquaculture</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2522</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">Scholarly Publications Librarian</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">23 Nov 2007 14:16</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=2522;">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=2522">item control page</a></p>
