Biology
Species | Latridopsis forsteri |
Common Name | Bastard Trumpeter |
Importance | Key |
Habitat | Exposed reef and sandy bottom |
Depth | ≤ 160 m (Edgar, 2008; May and Maxwell, 1986) |
Distribution | Sydney (New South Wales) to southern South Australia, Tasmania, southern New Zealand (Edgar, 2008) |
Diet | Small fish, invertebrates (Edgar, 2008) |
Stock Structure | No information available |
Movement | Schooling fish, usually in small numbers; large individuals occur in deeper waters; juveniles tend to remain associated with areas of reef for periods of time (Edgar et al. 2014; Gomon et al. 2008) |
M (Natural Mortality) | Undetermined |
Maximum Age (years) | 20 (Murphy and Lyle, 1999) |
Maximum Length (total length; cm) | 65 (Edgar, 2008) |
Maximum Weight (g) | 4000 (Edgar, 2008) |
Unsexed K (von Bertalanffy growth parameter) | 0.144 (Gomon et al. 2008; Murphy and Lyle, 1999) |
Unsexed t0 (age (years) when length = 0) | -2.9 |
Unsexed L∞ (asymptotic von Bertalanffy length (fork length; cm)) | 59.4 |
Size at Maturity (fork length (cm) at sexual maturity) | 45 |
Age at Maturity (years at sexual maturity) | 4 (Murphy and Lyle, 1999) |
Spawning Season | Late winter (Murphy and Lyle, 1999) |
Early Life History | Small juveniles settle from plankton on reefs in large numbers at intervals of several years (Edgar, 2008) |
Gillnet Post Release Survival | High: 95-83% depending on gillnet soak time (Lyle et al. 2014) |
