“…Overall, the population was dominated by 1‐ to 5‐year‐old fish. This dominance of young fish has also been previously reported for S. ciliata (Stocks et al., ) and other sillaginids in Australia and Japan (Hyndes and Potter, , ; Sulistiono et al., ; Butcher and Hagedoom, ; Rahman and Tachihara, ; Kendall and Gray, ).…”

Summary The goal of this study was to examine the age and size composition, growth, reproductive biology and mortality of Sillago ciliata Cuvier, 1829 in one of the largest estuarine commercial fisheries in south‐eastern Australia. The study also aimed to present a qualitative comparison of latitudinal variations in some of these characteristics along the eastern Australian coastline. The sampled population contained fish aged up to 10 years with a maximum size of 39.2 cm fork length (LF), and was dominated by 1–5 year olds. Sexual divergence in both the age and size structure of the population was recorded. Female S. ciliata grew slightly faster and attained a greater maximum size (L∞ = 33.79 cm LF, k = 0.50 year−1 and t0 = −0.57 years) than males (L∞ = 29.73 cm LF, k = 0.49 year−1 and t0 = −0.67 years). Females also matured at a significantly larger size (19.13 cm) and older age (1.63 years) than males (size: 17.07 cm, age: 1.10 years). Reproductive activity was highest between September and March. There were no differences between males and females in terms of mortality rate; the estimated total population, natural and fishing mortality rates were Z = 0.64, M = 0.42 and F = 0.22, respectively. Although these mortality rates suggest that S. ciliata in the Clarence River are relatively resilient to current rates of exploitation, regular monitoring of their commercial and recreational catch as well as their population structure is recommended in order to maintain sustainable fisheries. Potential latitudinal shifts in the spawning period, age structure and growth of S. ciliata along eastern Australia were also revealed.

“…The above strong and positive relationships, together with those between the two species, provide further support for the conclusion that the patterns of otolith growth of P. laevigatus and L. inops are influenced in a similar manner by temperature. Such an influence parallels the situation with the otoliths in a number of other marine and freshwater fish species (Matta et al 2010;Stocks et al 2011;Black et al 2011Black et al , 2013Gillanders et al 2012). These positive relationships between otolith growth and water temperature parallel those exhibited by the metabolism and somatic growth of fishes and the water temperature in their environment (Pauly 1980;Hagen and Quinn 1991;Brander 1995;Portner et al 2001).…”

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.

“…The combined results from these 2 studies highlight the plasticity in the growth characteristics of G. tricuspidata in eastern Australia. Inter-estuary and geographic variation in growth is common among fish species and can be dependent on a ple thora of biotic and abiotic factors (Sarre & Potter 2000, Sala-Bozano & Mariani 2011, Stocks et al 2011. Such observed variations in growth parameters among populations could, however, simply reflect sample differences between sexes and among estuaries (Sainsbury 1980, Kritzer et al 2001.…”

Girella tricuspidata is widely distributed and harvested by recreational and commercial fishers along the coastline of eastern Australia. The present study examined variability in the reproductive biology and growth of individuals within populations of G. tricuspidata across 3 estuaries (Clarence, Tuggerah and Tuross) and assessed population connectivity via a large-scale tagrecapture study in which fish were tagged across 9 estuaries. Spawning occurred predominantly between June and September in the Clarence River and between October and January in the Tuross River, suggesting that spawning occurs later in the year at higher latitudes. The recruitment of young to nursery grounds was spatially and temporally variable. G. tricuspidata are group-synchronous spawners, and the estimated batch fecundity was positively correlated with fish length. The estimated length and age at which 50% of G. tricuspidata attained reproductive maturity was similar for both sexes: ~286 mm fork length (FL) and 4.1 yr for males and 295 mm FL and 4.5 yr for females. G. tricuspidata were aged using otoliths to > 26 yr, whereas the reading of scales consistently underestimated the age of fish older than 5 yr. Growth was flexible but varied significantly between sexes and among estuaries; females grew faster than males and attained a larger asymptotic length in the Clarence and Tuross Rivers but not in Tuggerah Lake. Growth was rapid for both sexes until 4 to 5 yr of age, after which it slowed. Of the 6871 G. tricuspidata tagged, 15% were recaptured, with 96% of these fish recaptured in the estuary in which they were initially tagged. The recaptured individuals that migrated between estuaries predominantly displayed a northward movement into the prevailing coastal current, which is probably a life-history tactic to facilitate wide dispersal of eggs and larvae along eastern Australia.
