Port of Wellington: Baseline survey for non-indenous marine species. Inglis, G. J., Gust, N., Fitridge, I., Floerl, O., Hayden, B. J., & Fenwick, G. D.

Paper abstract bibtex Executive summary This report describes the results of a December 2001 survey to provide a baseline inventory of native, non indigenous and cryptogenic marine species within the Port of Wellington. • The survey is part of a nationwide investigation of native and non-native marine biodiversity in 13 international shipping ports and three marinas of first entry for yachts entering New Zealand from overseas. • Sampling methods used in these surveys were based on protocols developed by the Australian Centre for Research on Introduced Marine Pests (CRIMP) for baseline surveys of non-indigenous species in ports. Modifications were made to the CRIMP protocols for use in New Zealand port conditions. • A wide range of sampling techniques was used to collect marine organisms from habitats within the Port of Wellington. Fouling assemblages were scraped from hard substrata by divers, benthic assemblages were sampled using a sled and benthic grabs, and a gravity corer was used to sample for dinoflagellate cysts. Mobile predators and scavengers were sampled using baited fish, crab, starfish and shrimp traps. • The distribution of sampling effort in the Port of Wellington was designed to maximise the chances of detecting non-indigenous species and concentrated on high-risk locations and habitats where non-indigenous species were most likely to be found. • Organisms collected during the survey were sent to local and international taxonomic experts for identification. • A total of 336 species or higher taxa was identified from the Wellington Port survey. They consisted of 227 native species, 14 non-indigenous species, 26 cryptogenic species (those whose geographic origins are uncertain) and 69 species indeterminata (taxa for which there is insufficient taxonomic or systematic information available to allow identification to species level). • Sixteen species have not previously been described from New Zealand waters. Four of these were newly discovered non-indigenous species (a polychaete worm, Spirobranchus polytrema, a hydroid, Eudendrium capillare, a crab, Cancer gibbosulus, and an ascidian, Cnemidocarpa sp.). The remaining 12 species do not correspond with existing descriptions from New Zealand or overseas and may be new to science. • The 14 non-indigenous organisms described from the Port of Wellington included representatives of eight phyla. The non-indigenous species detected (ordered alphabetically by phylum, class, order, family, genus and species) were: (Annelida) Dipolydora armata, Polydora hoplura, Spirobranchus polytrema, (Bryozoa) Bugula flabellata, Cryptosula pallasiana, Cyclicopora longipora, Watersipora subtorquata, (Cnidaria) Eudenrium capillare, (Crustacea) Cancer gibbosulus, (Mollusca) Theora lubrica, (Phycophyta) Undaria pinnatifida, Griffithsia crassiuscula, (Porifera) Halisarca dujardini, (Urochordata) Cnemidocarpa sp. • The only species from the Port of Wellington on the New Zealand register of unwanted organisms is the Asian kelp, Undaria pinnatifida. This alga is known to now have a wide distribution in southern and eastern New Zealand.
