Eastern School Whiting Biology

Biology

SpeciesSillago flindersi
Common NameEastern School Whiting
ImportanceMinor
HabitatCoastal lakes, estuaries, and along outer coast
Depth≤ 170 m (Gomon et al., 2008)
DistributionEndemic to southeastern Australia; southern Queensland to western Victoria, around Tasmania (Gomon et al., 2008)
DietMainly crustaceans: amphipods, decapods, mysids, copepods (juveniles) (Burchmore et al., 1988)
Stock StructureSome evidence of four genetically distinct stocks: two in New South Wales, one in Tasmania, one in Victoria; Commonwealth assessments state that the evidence for separate stocks is weak and manage the species as a single stock (Dixon, 1987; Morison et al., 2012)
M (Natural Mortality)0.7 (Gray et al., 2014)
Maximum Age (years)7 (Kailola et al., 1993)
Maximum Length (standard length; cm)33 (Gomon et al., 2008)
Unsexed K (von Bertalanffy growth parameter)0.46
Unsexed t0 (age (years) when length = 0)-0.5
Unsexed L∞ (asymptotic von Bertalanffy length (fork length; cm))23.9 (Tilzey, 1994)
Size at Maturity (fork length; cm)14 – 16 (Hobday and Wankowski, 1987; Burchmore et al., 1988)
Age at Maturity (years)2 (Hobday and Wankowski, 1987; Burchmore et al., 1988)
Spawning SeasonSpring – late summer (Hobday and Wankowski, 1987)
Other Spawning InformationFemales release 30 000 – 110 000 eggs in total during spawning season (Hobday and Wankowski, 1987)
Early Life HistoryJuveniles inhabit inshore waters (Froese and Pauly, 2019)
