Quota units entitle the operator to take a certain
percentage of the TACC. The TACC is determined
annually for blacklip and greenlip abalone stocks
in each commercial fishing zone, and the process
used is outlined in the Abalone Fisheries
Management Plan (NRE 2002). The annual TACC
for each zone is applied to the quota units in that
zone to determine the available weight of catch
that can be taken by AFAL licence holders for the
fishing season.
Commercial processing
To enhance compliance under the quota
management system, a Fish Receiver Abalone
Licence (FRAL) is required to process abalone in
Victoria. Most of the commercial processors are
located in Melbourne and other coastal centres
such as Mallacoota and Port Fairy. FRAL holders
can receive abalone from Victorian commercial
divers as well as interstate abalone and
aquaculture product.
Recreational arrangements
A RFL is required to take abalone in the
recreational fishery (some exemptions apply).
Recreational fishing is also subject to a range of
additional input and output controls. In all parts of
Victoria the recreational bag limit for abalone is
five, and only two of the five can be greenlip
abalone. .
There is a permanent ban on the taking of all
abalone species from Central Victorian Waters,
except for 60 nominated days each year.
A range of size limits are in place to protect
breeding stocks, and recreational divers must:
 Carry a measuring device when fishing for
    abalone
 Not shuck abalone (remove the shell), or be in
    possession of shucked abalone, or land

3.3.2. Catch data
Total catch of target species
As no reliable estimate of the recreational catch is
available, the total catch is unknown.
Commercial catch of target species
The 2007-08 (quota year) TACC of 1174.2 tonnes
was fully caught. The breakdown of the TACC into
fishing zones is outlined in Table 1.

Incidental commercial catch
The take of abalone in other commercial Victorian
fisheries is not permitted.
Recreational catch
There is no reliable estimate of the recreational
catch of abalone in 2006/07. DPI considers
recreational catch to be low compared to the
commercial catch. The recreational catch was
greatest in the central zone due to the proximity of
this area to the large population in Melbourne.
Recent changes to fishing regulations have
restricted this catch
The last estimate of recreational catch of abalone
was undertaken between May 2000 and April 2001
in the National Recreational and Indigenous
Fishing Survey (Henry and Lyle 2003). This
estimate was 10,355 animals, weighing 3.1 tonnes.
