Background information on Mediterranean fanworm (Sabella Spallanzanii) to support regional response

Cawthron Institute was commissioned by Marlborough District Council under the Ministry of Science and Innovation's Envirolink medium advice grant scheme to conduct a desktop assessment of key technical information relating to this species, and provide an evaluation of the invasion potential and considerations for management within the Marlborough region. At the inception of the report Sabella was not believed to be present in the region, however in late February 2014, a small population was discovered on a boat moored in Waikawa Bay. As such, information regarding Sabella's biology, likelihood of establishment, potential for further spread, and impacts on key values is particularly timely.

Background Information on Sea Squirt (Pyura Doppelgangera) to support regional response decisions

Cawthron Institute was commissioned by Marlborough District Council under the Ministry of Science and Innovation's Envirolink medium advice grant scheme to conduct a desktop assessment of key technical information relating to this species, and provide an evaluation of the invasion potential and considerations for management within the Marlborough region. Information regarding Pyura's biology, likelihood of establishment, potential for further spread, and impacts on key values will enable effective decision-making around any future eradication or containment efforts.

Background Information to Support Management of the Clubbed Tunicate, Styela clava, in Picton

The clubbed tunicate, Styela clava is a type of sea squirt, and in New Zealand is a marine pest formally designated as an unwanted organism under the Biosecurity Act. In early June 2013, four Styela individuals were found in the inner part of Picton marina, representing the first reported range extension of Styela into Marlborough. The purpose of this report is to provide background technical information on the biology of Styela, summarise the results of two Styela surveys, and discuss some of the key requirements and considerations for effective management.

Brief on Incursion Exercise

A marine biosecurity incursion exercise was conducted by the Top of the South Marine Biosecurity Partnership at Port Nelson on 15 May 2013. The aim of this exercise was to test the effectiveness of the top of the South Partnership response procedures in the event a marine biosecurity threat is discovered. A secondary aim was for participants to learn by being involved or observing the exercise.

This report to the Nelson City Council reviews actions taken on notification of an incursion of the fanworm Sabella spallanzanii in Nelson Harbour. Identification has been confirmed but spawning is unlikely to have occurred due to immaturity of the specimens examined and that there appeared to be a single age class of worms on the vessel.

Vessel Hard-stand Survey and Biofouling Risk Factors

The TOS Marine Biosecurity Partnership has focused some of its activities on better understanding and managing biofouling risks from recreational vessel movements. Work over the last two summers has included biofouling assessments of recreational boats from across the TOS region, along with surveys of boaters to better understand their voyage habits and maintenance practices. Simultaneous with the summer work, biofouling assessments and boater surveys have been undertaken by appropriately-trained travel-lift operators at the Nelson and Waikawa hard-stands. The first part of this report describes the hard-stand survey work, and compares the results to previous summer survey findings. In the second part of the report, combined data from the summer surveys and hard-stand study are used to explore the extent to which levels of fouling on recreational vessels are related to boater practices with respect to antifouling, cleaning and boat usage, as these are all recognised risk factors.

Vessel Hull Fouling Report 2013

Vessel Hull Fouling Survey 2016

The Top of the South (TOS) Marine Biosecurity Partnership has been focusing some of its activities on better understanding and managing biofouling risks from recreational vessel movements. There are several thousand recreational vessels at marina berths or on swing moorings in the TOS region, as well as vessels that visit from areas outside the TOS. This study found that recreational vessels pose a significant biosecurity risk to many of the locations with important values in the Top of the South (TOS).

The survey focused on locations outside of the main vessel hubs, and included areas commonly visited by boaters from other regions. The key findings described reinforce the potential role of recreational vessels in the spread of marine pests, and highlight the importance of managing this pathway effectively.
