Marine High Risk Site Surveillance Programme: Annual report for all High Risk Sites 2015–16 (Project 12099) [link]Paper  doi  abstract   bibtex   
The Marine High Risk Site Surveillance (MHRSS) Programme is a national programme of surveys that are targeted at the early detection of particular High Risk marine non-indigenous species (NIS). The primary objective of the MHRSS Programme is to detect incursions of New to New Zealand non-indigenous organisms listed on the Unwanted Organisms Register at High Risk Sites throughout New Zealand. The MHRSS Programme also has two secondary objectives, which are: (i) to detect incursions of marine NIS or cryptogenic organisms not previously recorded in New Zealand, and; (ii) to detect range extensions by marine NIS or cryptogenic organisms that are already established in New Zealand waters. The MHRSS Programme is designed to detect the presence of a group of five primary (Asterias amurensis, Carcinus maenas, Caulerpa taxifolia, Eriocheir sinensis and Potamocorbula amurensis), and four secondary (Arcuatula senhousia, Eudistoma elongatum, Sabella spallanzanii and Styela clava) target non-indigenous marine animals and plants. This Annual Report details the targeted surveillance surveys at the 11 High Risk Sites (ports and marinas) covered by the MHRSS Programme during the periods May–September 2015 (the Winter 2015 round of surveys) and November 2015–March 2016 (the Summer 2015–16 round of surveys). The number of locations sampled met the target sampling effort on all surveys, apart from the Winter 2015 Otago Harbour survey (99.6% target achieved – sampling count error in the field), with 2934 locations (101.1% of target) surveyed during Winter 2015, and 2918 locations (100.5% of target) surveyed during Summer 2015–16. No primary target species were detected, but all four secondary target species were detected at various locations and times: Arcuatula senhousia was recorded during the following surveys: Auckland (Winter2015, Summer 2015–16); and Whangarei (Winter 2015, Summer 2015–16). Eudistoma elongatum was recorded during the following surveys: Opua (Winter 2015,Summer 2015–16); and Whangarei (Winter 2015, Summer 2015–16). Sabella spallanzanii was recorded during the following surveys: Auckland (Winter2015, Summer 2015–16); Lyttelton (Winter 2015), Nelson (Winter 2015, Summer2015–16); Tauranga (Summer 2015–16); Wellington (Summer 2015–16); andWhangarei (Winter 2015, Summer 2015–16). Styela clava was recorded during the following surveys: Auckland (Winter 2015, Summer 2015–16); Lyttelton (Winter 2015, Summer 2015–16); Nelson (Winter 2015, Summer 2015–16); Opua (Winter 2015, Summer 2015–16); Otago (Winter 2015, Summer 2015–16); Picton (Winter 2015, Summer 2015–16); Tauranga (Winter 2015, Summer 2015-16); Wellington (Summer 2015–16); and Whangarei (Winter 2015, Summer 2015–16). Numbers of specimens collected and sent to the Marine Invasives Taxonomic Service (MITS) for formal identification per survey ranged from none to 16, and the total numbers of specimens sent were 28 for the Winter 2015 round of surveys and 72 for the Summer 2015–16 round. Seven of the 28 specimens sent to MITS from the Winter 2015 survey were NIS, including the red algae Grateloupia turuturu and Schizymenia apoda (both Lyttelton), the colonial ascidians Botrylloides leachii and Didemnum vexillum (both Opua), and the bryozoans Celleporaria nodulosa (Tauranga) and Celleporaria umbonatoidea (Opua). The record of S. apoda from Lyttelton represents a MHRSS Programme range extension (previously known from Otago, Picton and Wellington harbours). Twenty-seven of the 72 specimens sent to MITS from the Summer 2015–16 survey were NIS, including the brown algae Stictyosiphon soriferus (Wellington) and Undaria pinnatifida (Port Taranaki and Wellington), the red algae Grateloupia turuturu (Port Taranaki) and Griffithsia crassiuscula (Otago), the caprellid amphipod Caprella mutica (Picton), the annelid (polychaete worm) Sabella spallanzanii (Auckland and Tauranga), the colonial ascidian Botrylloides leachii (Otago), the solitary ascidians Ascidiella aspersa (Otago), Ciona intestinalis (Picton), Clavelina lepadiformis (Picton), Polyandrocarpa zorritensis (Whangarei) and Styela clava (Tauranga), the bryozoan Amathia verticillata (Auckland, Nelson and Tauranga), and the sponge Halisarca dujardini (Wellington). The record of P. zorritensis from Marsden Cove Marina in Whangarei Harbourrepresents a MHRSS Programme range extension (previously known fromTauranga). The record of C. mutica from Waikawa Marina in Picton represents a MHRSSProgramme range extension (previously known from Bluff, Lyttelton and Otago). The record of C. lepadiformis from Waikawa Marina in Picton represents a MHRSSProgramme range extension (previously known from Nelson). A sponge collected during the Whangarei Harbour summer survey (Phlyctaenopora (Barbozia) n. sp.) represents a New to New Zealand native species. MPI was informed of the range extensions and New to New Zealand species at the time of collection, or the time that specimen identity was confirmed.
