Measuring shell hardness in Southern Rock Lobster (Jasus edwardsii) using a durometer

Abondance et diversité de poissons Abondance et distribution des invertébrés

Southern Rock Lobster (Jasus edwardsii) that are about to moult or have recently moulted have reduced market value due to higher mortality in live transport, higher cannibalism and lower meat recovery.

Limiting the landing of softer shelled lobsters is desirable to maintain product quality.

The effects of several factors on durometer readings were evaluated: sex, temperature (ambient plus elevated 3°C), location (from around the coast), and size (carapace length).

Individuals were collected across two regions South Australia and Tasmania.
