Minimum commercial size limits and Total Allowable Catch (TAC) apply to native periwinkles and short-spined sea urchin. When the TAC for a species/zone is reached, or a within-zone catch-capped area, it is seasonally closed for the remainder of the licensing year (1 Sep to 31 Aug).
Current closures and limits are displayed below, together with catch updates. Within-season catch data cannot be disclosed until that area has been fished by five or more divers. Only data entered in the NRE Tas Fisheries FILMS database is included.

Biosecurity closures and recommended no take areas
Biosecurity closures and recommended no take areas
The Commonwealth Department of Agriculture, Water and Environment (DAWE), along with Biosecurity Tasmania (BT), have advised that all commercial dive species should be considered and monitored in line with the abalone biotoxin management regime. NRE Tas is supporting IMAS projects to assess whether urchins and periwinkles can be managed in their own right.
In the interim, it is strongly recommended that commercial dive species are not taken from abalone blocks that are closed to the take of abalone by DAWE or BT due to biotoxins. The abalone block map can be found on the
Abalone Fishery webpage.
DAWEs recommended no take abalone blocks:
Block 24 A, Block 24 B and Block 24 C;Block 25;Block 26A, 26B and 26C; and
Block 30A
