New report shows boat owners are picking up what we're putting out there

7/9/2021

 
How much do Auckland boat owners know about marine biosecurity? And does this translate to improvements in practice? Auckland Council has now released the results of its second annual boat owner survey. The good news is it shows significant improvement in terms of understanding and uptake of marine biosecurty principles, which translates directly to better protection for our coastal environments.

Following the science - a new page connecting you to scientific sources

7/9/2021

 
New Zealand’s efforts to protect its coastlines from marine pests is pioneering and scientists world-wide are continuing to build on the field of research. 
 
When New Zealand introduced requirements for all boats entering the country to meet strict conditions relating to both ballast water and biofouling, it became the first country in the world to take active steps to protect its coastlines from marine pests. 
 
Every decision made in New Zealand has been done with the confidence of scientific knowledge that confirms it is the right thing to do, and marine scientists, both here and abroad, are continuously adding to a body of research, developing detection technologies and management approaches to help keep our coastlines safe from marine pests. 
 
The updated ‘Knowledge’ page on Marinepests.nz has links to a number of important studies on marine pests and suggestions of places where you can find out more about work undertaken by the scientific community that is working on these issues. 
 
Marine biosecurity is still a relatively new field and it’s of global environmental importance. The aim is to protect our marine environment.  This in turn protects our fisheries, our aquaculture, our tourism industry – and also the places we love visiting and the things we love doing when we visit them. 

The hunt for marine pests gets back underway

7/9/2021

 
Summer surveillance is set to get underway again soon, with divers in Northland, Auckland, Bay of Plenty, Waikato (Coromandel), Gisborne and Hawkes Bay and checking moored and berthed vessels, and marine structures for marine pests. ​
They are looking out for species including Asian date mussel (Arcuatula senhousia), Australian droplet tunicate (Eudistoma elongatum), clubbed tunicate (Styela clava), sea squirt (Clavelina oblonga) and Mediterranean fanworm (Sabella spallanzanii).

Other unwanted species not known to be in New Zealand yet – but which divers will also be vigilant for – include northern Pacific seastar (Asterias amurensis), European green crab (Carcinus maenas) the green alga (Caulerpa taxifolia), Chinese mitten crab (Eriocheir sinensis) and Asian clam (Potamocorbula amurensis).
 
If a marine pest is found, it’s likely that the council will be in contact with the boat or structure owner to let them know and to arrange for cleaning, if needed. Steps taken will depend on the pest found, and the level of biofouling. ​
