“…These results suggest that females grew faster and attained greater FLs than males (a previous study on A. australis did not discriminate between genders; Pollock 1982). This result is consistent with reports on many other Sparidae (Morison et al 1998, Pajuelo & Lorenzo 2000, Pajuelo et al 2006, Alós et al 2010), but gender-related growth patterns in contrast to this are apparent within the family (Pajuelo & Lorenzo 2003, Brouwer & Griffiths 2004, Dulčić et al 2011) and can be confounded due to the prevalence of protandric hermaphroditism displayed by several species, including A. australis (Pollock 1982, Buxton 1993, Pajuelo & Lorenzo 2000, Abou-Seedo et al 2003, Pajuelo et al 2006). Further work is required to determine the levels and effects of hermaphroditism on s exspecific growth rates of A. australis.…”

“…The growth of sparid species tends to be very fast in the first years of life, slowing down considerably afterwards (Pajuelo, Martinez, Gonzalez, Lorenzo, Garcia‐mederos, Dominguez‐Seoane & Hernandez‐cruz 2006). Morales‐Nin and Moranta (1997) found for common dentex ( Dentex dentex L.) that growth proceeded at a fast pace during the first 2 years, with animals reaching around 24 cm at 1 year, and slowing down during adulthood.…”

A 4-year study (May1997^December 2000 of the reproductive biology of pink dentex Dentex gibbosus (Ra¢nesque) from the Adriatic Sea revealed that this species is a rudimentary hermaphrodite. The smallest mature males and females captured were 38.70 cm in total length (T L ) and 39.80 cm in total length (T L ) respectively. The von Bertalan¡y growth parameters estimated for the entire population were: L 1 5107.24, K 5 0.12 and t 0 5 À 0.90. Fifty per cent of the population were sexually mature at 41.50 cm T L , while 100% of the specimens were sexually mature at 57.00 cm T L . Both monthly gonadosomatic index and macroscopically determined gonad stages strongly indicate that the pink dentex from the Adriatic Sea spawn partially in August, September and October. The mean value of absolute fecundity (F) was 1672 Â 10 6 eggs. The results of great fertility of the pink dentex, partial spawning and relatively late sexual maturation suggest that the pink dentex has a high potential for commercial culture.

“…G ROW T H Like many other sparids, the Acanthopagrus hybrid complexes examined here show longevity, attaining ages of up to 20 years (Chale-Matsau et al, 2001;Pajuelo et al, 2006). While this maximum age is similar to that observed for some western populations of pure A. butcheri (21 years), maximum ages of up to 29 and 31 years, respectively, have been reported for the putative hybrid complexes in southern Australia and other pure populations in the west (Morison et al, 1998;Sarre, 1999;Sarre & Potter, 2000;Potter et al, 2008).…”

This study examined the spatio-temporal reproductive patterns, population structure, maturity and growth of Acanthopagrus hybrid complexes, which comprise mainly black bream Acanthopagrus butcheri and the hybrids they form with yellowfin bream Acanthopagrus australis, in two Australian estuaries (Coila and Brou Lakes, NSW). There were no differences between pure A. butcheri and hybrids in terms of their population structure, growth and maturity, suggesting that these two breeds have similar life histories and may therefore be managed as single, naturally cohesive units. Sexual variation in size structure was only observed for the complex in Coila Lake. Although there was significant variation in age structure between estuaries, both complexes exhibited dominance of only a few year classes indicating episodic recruitment and high fishing mortality. Acanthopagrus eggs occurred in higher numbers within upstream creek habitats compared to lake habitats, thereby highlighting the need to protect these spawning habitats. Although maturity in the complexes was not influenced by gender or estuary, differences in growth were detected between the genders and estuaries.
