Total Allowable Catch is the total amount of abalone that can be taken from Tasmanian waters in any calendar year. It is determined annually by the Minister on advice from the Abalone Fishery Core Group (FCG). The FCG takes into account a measurement of catch called Catch Per Unit Effort (CPUE) in each block when making its recommendation to the Minister for the following year.

Determining the TAC is guided by a process of stock assessment, carried out by IMAS.

An allowable catch needs to be set for each zone in the fishery, which together comprises the Total Allowable Catch (TAC). Each of the 3,500 quota units then provides access to the same amount of abalone in each zone, and the fishery as a whole.

The yearly TAC is divided by 3,500 to determine the amount of each quota unit provides for the year. As the TAC changes, the quota units are amended each year corespondingly.

The TAC for 2024 is 756,000 tonnes, allocated as follows:

ZONE TAC – kg TAC – kg/unit
Bass Strait 80,500 23
Eastern 231,000 66
Greenlip 67,500 25
Northern 63,000 18
Western 294,000 84
TOTAL 756,000 216
