Two methods of otolith increment analysis were used to describe spatial, temporal and gender variation in growth of sand whiting, Sillago ciliata (Cuvier), in four south-east Australian estuaries. Mean annual standardised otolith increment widths were used as indices of individual lifetime growth rates, while raw otolith increment widths were used to describe variation in growth throughout the life of S. ciliata. Temporal variation in growth was observed at an annual scale, while spatial variation in growth was observed between estuaries. Growth rates increased significantly with decreasing latitude and greater mean sea surface temperatures. A divergence in growth rates between sexes was detected, with females growing faster than males after sexual maturity. This study highlights how otolith increment analyses can: (1) be used to analyse temporal trends in growth from a single sample and (2) provide insight into juvenile growth when samples have an absence of undersized fish.

“…However, caging studies are labor intensive and suffer to an unknown degree from artifacts including handling stress, accumulation or exclusion of prey items, and (or) the restriction of natural movement (Able 1999;Meng et al 2000), all of which could confound the response of growth rates to the environmental parameter(s) of interest. Microstructural analysis of hard parts (e.g., otoliths) as a proxy for short-term growth rates may also be useful (see Rakocinski et al 2006), but may also lack the temporal resolution over the time scales of interest in hypoxia studies.…”

The ratio of RNA to DNA (RNA:DNA) in white muscle tissue of juvenile summer flounder (Paralichthys dentatus) and weakfish (Cynoscion regalis) was used as a proxy for recent growth rate in an estuarine nursery. Variability in RNA:DNA was examined relative to temporal changes in temperature and dissolved oxygen (DO). Initial laboratory experiments indicated (i) a strong positive relationship between RNA:DNA and growth rate, (ii) a rapid response of RNA:DNA to changes in feeding, and (iii) no effect of hypoxia on the relationship between RNA:DNA and growth rate (tested in weakfish only). Diel cycling DO occurred in the nursery throughout the summers of 2002 and 2003. Canonical correlation analysis of field data indicated a strong positive relationship between RNA:DNA and mean DO conditions prior to capture in both species. Correlations were weak or insignificant between stomach content mass (an index of feeding) and mean DO and between RNA:DNA and stomach content mass and DO variability. These results suggest a strong functional relationship between DO concentration and the growth rate of juvenile fishes in an estuarine nursery. Furthermore, growth rates of wild-caught fishes (estimated from RNA:DNA) appear to be more negatively impacted by diel cycling hypoxia than would be expected from published laboratory data. Résumé: Le rapport ARN sur ADN (ARN:ADN) dans le tissu du muscle blanc du cardeau d'été (Paralichthys dentatus) et de l'acoupa royal (Cynoscion regalis) a servi de mesure de remplacement du taux de croissance récent dans une nourricerie estuarienne. Nous avons examiné la variabilité d'ARN:ADN en fonction des changements temporels de température et d'oxygène dissous (DO). Des expériences initiales en laboratoire indiquent (i) une forte relation positive entre ARN:ADN et le taux de croissance, (ii) une réaction rapide de ARN:ADN aux changements d'alimentation et (iii) une absence d'effets de l'hypoxie sur la relation entre ARN:ADN et le taux de croissance (testée seulement chez l'acoupa royal). Il y a eu un cycle journalier de DO dans la nourricerie tout au cours des étés 2002 et 2003. Une analyse des corrélations canoniques des données de terrain montre une forte relation positive entre ARN:ADN et les conditions moyennes de DO avant la capture chez les deux espèces. Les corrélations sont faibles ou insignifiantes entre la masse du contenu stomacal (un indice alimentaire) et la valeur moyenne de DO et entre ARN:ADN et la masse du contenu stomacal et la variabilité de DO. Ces résultats indiquent une forte relation fonctionnelle entre les concentrations de DO et le taux de croissance des jeunes poissons dans une nourricerie estuarienne. De plus, les taux de croissance des poissons capturés en nature (estimés d'après ARN:ADN) semblent être affectés plus négativement par l'hypoxie cyclique journalière que ne le laissent prévoir les données de laboratoire de la littérature.

“…Daily proportional growth for every outer increment of each fish was estimated from the increment width relative to the otolith radius (Rakocinski et al, 2000). Consecutive proportional growth values of individual fish were ontogenetically standardized (Rakocinski et al, 2006). For each date over the 38-day study period, mean and standard deviation (S.D.)…”
