Marine high-risk site surveillance Annual report for all ports and marinas 2011–2012 (Project 12099) [link]Paper  abstract   bibtex   
The Marine High-Risk Site Surveillance programme of targeted surveillance for nonindigenous marine species (NIS), delivered by NIWA under contract to the Ministry for Primary Industries (MPI), is designed to detect the presence of a group of five primary and four secondary target non-indigenous or potentially invasive marine animals and plants that MPI have identified as presenting a significant risk of arriving and establishing in New Zealand. It also aims to monitor changes in the distribution of established non-indigenous or pest species. This annual report details the targeted surveillance surveys in the 11 ports and marinas covered by the programme during the periods June - September 2011 (the Winter 2011 round of surveys) and November - March 2012 (the Summer 2011-2012 round). Target numbers of locations sampled met the target on all but three occasions, and all were within 96% of target or higher. Failure to achieve target was often due to loss of traps by, for example, theft. The four secondary target species were all detected: • Eudistoma elongatum was recorded during the following surveys: Opua (Winter 2011, Summer 2011-2012), Whangarei (Winter 2011, Summer 2011-2012). • Musculista senhousia was recorded during the following surveys: Auckland (Winter 2011, Summer 2011-2012), Tauranga (Winter 2011, Summer 2011-2012), Whangarei (Winter 2011, Summer 2011-2012). • Sabella spallanzanii was recorded during the following surveys: Auckland (Winter 2011, Summer 2011-2012), Lyttelton (Winter 2011). • Styela clava was recorded during the following surveys: Auckland (Winter 2011, Summer 2011-2012), Dunedin (Winter 2011, Summer 2011-2012), Nelson (Winter 2011, Summer 2011-2012), Opua (Winter 2011, Summer 2011-2012), Tauranga (Summer 2011-2012 – range extension), Whangarei (Winter 2011, Summer 2011- 2012). Numbers of specimens sent to MITS per survey ranged from none to 11, and the total number of specimens sent were 25 for the Winter 2011 round and 33 for the Summer 2011-2012 round. Nine of the specimens sent to MITS from the Winter 2011 survey were NIS, including Caprella mutica (from the hull of a resident yacht in Bluff), Sabella spallanzanii (Lyttelton), Grateloupia turuturu (Nelson and New Plymouth) and Styela clava (Nelson). None of them were new records and only C. mutica represented a range extension. Seven of the specimens from the Summer 2011-2012 survey were NIS, including Grateloupia turuturu (New Plymouth) and Styela clava (Tauranga), the latter representing a range extension. Three specimens of the penaeid prawn Metapenaeus bennettae and three of the hippollytid prawn Lysmata californica were collected in Whangarei in Summer 2011-2012. M. bennettae has previously been recorded only in Waitemata Harbour, where it was first detected in August 2009. The incomplete head of a specimen of L. californica was collected during the Summer 2009-2010 surveillance of Whangarei, but could not be identified to species because of lack of material. The more recent specimens confirm that the previous individual was most probably of the same species and represented the first record of this species in New Zealand or the western Pacific. Two of the specimens of L. californica were gravid.

This annual report details the targeted surveillance surveys in the 11 ports and marinas
covered by the programme during the periods June - September 2011 (the Winter 2011 round
of surveys) and November - March 2012 (the Summer 2011-2012 round).
Target numbers of locations sampled met the target on all but three occasions, and all were
within 96\% of target or higher. Failure to achieve target was often due to loss of traps by, for
example, theft.
The four secondary target species were all detected:
• Eudistoma elongatum was recorded during the following surveys: Opua (Winter 2011,
Summer 2011-2012), Whangarei (Winter 2011, Summer 2011-2012).
• Musculista senhousia was recorded during the following surveys: Auckland (Winter
2011, Summer 2011-2012), Tauranga (Winter 2011, Summer 2011-2012), Whangarei
(Winter 2011, Summer 2011-2012).
• Sabella spallanzanii was recorded during the following surveys: Auckland (Winter
2011, Summer 2011-2012), Lyttelton (Winter 2011).
• Styela clava was recorded during the following surveys: Auckland (Winter 2011,
Summer 2011-2012), Dunedin (Winter 2011, Summer 2011-2012), Nelson (Winter
2011, Summer 2011-2012), Opua (Winter 2011, Summer 2011-2012), Tauranga
(Summer 2011-2012 – range extension), Whangarei (Winter 2011, Summer 2011-
2012).
Numbers of specimens sent to MITS per survey ranged from none to 11, and the total number
of specimens sent were 25 for the Winter 2011 round and 33 for the Summer 2011-2012
round. Nine of the specimens sent to MITS from the Winter 2011 survey were NIS, including
