“…The presence of a significant correlation among the time series of widths of growth zones within individual otoliths demonstrates that such a driving factor is influencing growth. The patterns of otolith growth have also been subjected to mixed modelling and age-specific regression to explore the relationship between somatic growth and environmental variables on multiple populations of a given species and of co-occurring species (Thresher et al 2007;Neuheimer et al 2011;Morrongiello et al 2012). The relationships between the trends exhibited by the increment widths in otoliths and variables such as water temperature are of importance in predicting the effects of climate change (e.g.…”

laevigatus (maximum age 20 years) and L. inops (maximum age 21 years) were synchronised within and between species. The correlation between the two master otolith chronologies, i.e. mean standardised increment width for each year, was highly significant (P < 0.01). The master otolith chronology for each species was positively correlated with mean sea surface temperatures from 1 July to 30 June, which encompassed the austral summer when growth is typically greatest, and with mean monthly sea surface temperature between September andMarch. Leeuwin Current strength, which influences the biotic characteristics of some marine species on the south coast, has little influence on the pattern of otolith growth, presumably because the inter-connected embayments from which fish were obtained were partially enclosed. On the basis of the above data and the geographical distributions of P.laevigatus and L. inops, it is proposed that, while both species would grow faster with increasing temperature, the temperatures on the south coast are closer to the optimum for the former species.

“…These climate-growth relationships agree with the expectation that warming climate and shoaling thermoclines will reduce production in low-latitude pelagic systems that are already nutrient limited (Behrenfeld et al 2006), increase production in high-latitude pelagic systems (Mueter et al 2009), and add the prediction that limited warming will also increase nearshore benthic production in the California Current and Alaska Coastal Current systems. Moreover, otolith growth indices can be explicitly incorporated in stock assessment models under an ecosystembased approach to management as either an indication of species biomass (Morrongiello et al 2012) or as an indication of habitat. For instance, the otolith growth index of a nearshore resident fish could prove useful in models of other commercial fish species that have critical early life history stages in nearshore systems (Agardy et al 2005;Laurel et al 2007;Echave et al 2012;Johnson et al 2012).…”

“…While otolith-based approaches assume that annual increments in length are directly proportional to those in the otolith, such a relationship is not always the case with, for example, otoliths typically continuing to grow after the growth in the body has slowed markedly or even ceased (e.g. Campana, 1990;Morrongiello et al, 2012). At the same time, however, it is likely that, in terms of body length, any relationship between growth and an environmental variable will be mirrored by a similar trend with otolith growth (Morales-Nin, 2000).…”

“…Thus, in those other studies, variations in the widths of the growth zones in otoliths to develop chronologies for the relative growth of otoliths in different years and in mixed-effect models to determine inter alia the influence of age and year on otolith growth (e.g. Weisberg et al, 2010;Morrongiello et al, 2012;Coulson et al, 2014). Otolith-based approaches have been employed in studies of A. butcheri in estuaries further east in Tasmania and South Australia (Doubleday et al, 2015) and of another estuarine species, P. colonorum, in Victoria (Morrongiello et al, 2014).…”

Factors influencing growth of Acanthopagrus butcheri (Sparidae) in a eutrophic estuary have changed over time

The overall growth of Acanthopagrus butcheri in the eutrophic Swan River Estuary has previously been shown to decline between 1993-95 and 2007-11. This was attributed to the effects of an increase in hypoxia on A. butcheri in deeper water, brought about by reductions in freshwater flushing, and to density-dependent effects as this species became concentrated in the better-oxygenated, nearshore shallow waters. In the present study, a year-effect model was developed that provided a good fit to the lengths at age and could thus be used to explore the following: 1) The extent to which somatic growth of A. butcheri differed between years in the above two periods and within the later period, which was extended to include data for 2012 to 2014, and 2) whether annual growth in 2007-14 was related to temperature and/or freshwater discharge. Annual length increments for females and males during the second year of life, predicted from the model using a common initial length, were almost invariably less in each year in 2007-14 than in 1993-95. In 2007-14, these predicted increments varied by ~2 times for both females and males and were positively correlated with average temperature during the main growth phase of A. butcheri. They were not significantly correlated, however, with freshwater discharge in the preceding cool wet 'winter' months, when the vast majority of rainfall occurs.The demonstration that the growth of A. butcheri was positively correlated with temperature for years in the latter period is consistent with the metabolic theory of ecology and contrasts with M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT2 growth declining between 1993-95 and 2007-14 when temperatures were increasing. Thus, any influence of temperature on growth between those periods was overridden by other factors, i.e. hypoxia and increased densities. As A. butcheri completes its life cycle within its natal estuary and has plastic biological characteristics, it is an ideal candidate for use as an indicator of the health of an estuary and for hypothesising on the effects of climate change on fish species.
