Biology
| Species | Nototodarus gouldi |
| Common Name | Gould’s squid |
| Importance | Minor |
| Habitat | Open water; coastal, inner shelf and shelf break waters |
| Depth | ≤ 600 m (Stark, 2008) |
| Distribution | Southern Queensland to mid-Western Australia, around Tasmania (Dunning, 1998; Dunning and Förch, 1998) |
| Diet | Small planktonic crustaceans, fish, squid (Machida, 1983; O’Sullivan and Cullen, 1983; Smith, 1983; Uozumi, 1998; Pethybridge et al., 2012) |
| Stock Structure | Uncertain, appears only one population in southern Australia |
| Movement | Move widely within a 300 km2 area but no large-scale migration between feeding and spawning areas as for other similar squid species (Jackson et al., 2005a; Triantafillos et al., 2004) |
| M (Natural Mortality) | Undetermined |
| Maximum Age (years) | 1 (Jackson et al., 2005b) |
| Maximum Length (mantle length; cm) | 40 (Norman and Reid, 2000) |
| Maximum Weight (g) | 1600 (Norman and Reid, 2000) |
| Growth Rate (non-von Bertalanffy) | 2.559 – 5.596 g/day (females), 1.622 – 5.307 g/day (males); size-at-age highly variable between individuals, years, and locations (Jackson et al., 2003; Jackson et al., 2005b) |
| Size at Maturity (length (mantle length; cm) at which 50% of population are sexually mature) | 30.6-31.4 (females), 20.5-21.5 (males) (Stark, 2008) |
| Spawning Season | Year-round |
| Additional Spawning Information | Semelparous; egg masses are free-floating gelatinous sphere of at least 1.5m diameter, containing several thousands of eggs (Jackson et al., 2005b; Uozumi, 1998; O’Shea et al., 2004) |
| Recruitment | Highly variable; no-stock recruitment established |
| Early Life History | Hatching throughout year (Jackson et al., 2005b; Uozumi, 1998) |
