Catch and Closures Information

​​​​​​​​​​​​​​​​​​​​​​In the interset of sustainability, the amount of perwinkles and short spined sea urchins that can be harvested from defined areas (zones) is limited by allocating a Total allowable catch (TAC) for the area.  Once the TAC is reached the zone is closed for the remainder of the licensing year.  

Below are the progressive commercial catches for the licensng year. ​​

Biosecurity closures and recommended no take areas

Advice has been received from the Commonwealth Department of Agriculture and Water and Biosecurity Tasmania that commercial dive species (periwinkles, centrostephanus and heliocidarisshould be considered similar to abalone in relation  to biotoxin management as they are all predominantly grazers.  

It is therfore strongly recommended that commercial dive species should not be taken from abalone blocks that are closed to the take of abalone by the Department of Agriculture and Water (DAW) due to biotoxins.  

DPIPWE is currently working with IMAS to gather enough commercial dive samples to provide sufficient data for urchins and periwinkles to be managed under their own right but this is expected to take two to three years to allow enough comparisons of PST uptake to be made between species over a variety of conditions to allow informed decisions to be made.

Over the interem, the Department is working with DAW and Biosecurity Tasmania to adopt more approriate management arrangements until sufficient data is acquired.  

  As a precaution, it is recommended that for the time being, these areas should not be fished by the commercial dive sector.   It is therefore strongly recommended that no periwinkles or sea urchins (Centrostephanus or Heliocidaris) be taken from the following  blocks as depicted on the attached abalone block maps . 

Recommended no take blocks:

Block 24 A, Block 24 B and Block 24 C;

Block 25; and

Block 26A, 26B and 26C.

  Blocks 24 A, B, C   (373Kb)

  Blocks 25 and 26A, B C   (356Kb)
