Biology
| Species | Notolabrus fucicola |
| Common Name | Purple Wrasse |
| Importance | Key |
| Habitat | Predominantly on exposed reefs |
| Depth | ≤ 90 m (Edgar, 2008) |
| Distribution | New Zealand and Australian waters, from southern New South Wales to Kangaroo Island (SA) (Edgar, 2008) |
| Diet | Molluscs and crustaceans (Denny and Schiel, 2001) |
| Stock Structure | No information available |
| Movement | Site-attached, with no evidence of territorial behaviour. Movements between reefs is limited and likely to be restricted to a small proportion of the population (Barrett, 1995b) |
| M (Natural Mortality) | 0.2 (low adult mortality for both species, estimated for N. tetricus) (Barrett, 1995b; Smith et al., 2003) |
| Maximum Age (years) | 24 (Welsford, 2003) |
| Unsexed K (von Bertalanffy growth parameter) | 0.85 |
| Unsexed t0 (age (years) when length = 0) | -3.23 |
| Unsexed L∞ (asymptotic von Bertalanffy length (fork length; cm)) | 44.7 |
| Length (FL; fork length (cm))– Weight (W; g) Relationship | W=0.0161L^3.0407 (Barrett, 1995b; Welsford, 2003) |
| Size at Maturity (length (fork length; cm) at which 50% of population are sexually mature) | 18.41 (females) |
| Age at Maturity (age (years) at which 50% of population sexually are mature)) | 3 (females) Barrett, 1995a; Harwood, and Lokman, 2006) |
| Sexual development | Gonochoristic |
| Spawning Season | August – January |
| Additional Spawning Information | Batch fecundity is estimated at 74500 ± 34900 eggs/kg (Barrett, 1995b) |
| Early Life History | Planktonic larval duration ranges from 40 – 87 days; settlement on reefs at around 10.4 mm (Welsford, 2003) |
