Reseeding involves the growing of juveniles in land based hatcheries
(to approx 20mm) and then out-planting them onto the coast.
There are reseeding trials running in Pau3, Pau4, Pau5A, Pau5B,
Pau5D and Pau7 and much has been learnt in the last 5 years about
the methodology and preferred habitat of juvenile paua.
The
survival rate of between 15 to 20% (from out-planting to harvest)
shows that this method of enhancement could become an extremely
important fisheries management tool in the future.
To implement reseeding at a commercial scale, paua quota owners
would need to pay approximately $2000 per tonne per year of quota
owned so that the industry could purchase sufficient seed stock.
Over the next few years it is anticipated that this will happen.
Used in conjunction with other fisheries management tools, reseeding
could prove to be the back-bone of re-building paua fisheries to
their bio-mass levels of 10 to 15 years ago.
