Port of Timaru: 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 February 2002 baseline survey to provide a baseline inventory of native, non-indigenous and cryptogenic marine species within the Port of Timaru. • 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 Timaru. 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 Timaru 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 282 species or higher taxa was identified from the Timaru Port survey. They consisted of 177 native species, 16 non-indigenous species, 27 cryptogenic species (those whose geographic origins are uncertain) and 62 species indeterminata (taxa for which there is insufficient taxonomic or systematic information available to allow identification to species level). • Twenty-one species of marine organisms collected from the Port of Timaru have not previously been described from New Zealand waters. Three of these were newly discovered non-indigenous species (a crab, Cancer gibbosulus, an amphipod, Caprella mutica, and an ascidian, Cnemidocarpa sp.), and 18 are considered cryptogenic. The 18 cryptogenic species included eight species of amphipod, a pycnogonid, an ascidian, and eight species of sponge that did not match existing descriptions and may be new to science. • The 16 non-indigenous organisms described from the Port of Timaru included representatives of five phyla. The non-indigenous species detected (ordered alphabetically by phylum, class, order, family, genus and species) were: (Annelida) Euchone limnicola, Barantolla lepte, (Bryozoa) Bugula flabellata, Bugula neritina, Cryptosula pallasiana and Watersipora subtorquata, (Crustacea) Caprella mutica, Apocorophium acutum, Monocorophium acherusicum, Jassa slatteryi and Cancer gibbosulus, (Phycophyta) Undaria pinnatifida, Griffithsia crassiuscula, Polysiphonia subtilissima, (Urochordata) Ciona intestinalis and Cnemidocarpa sp. • The only species from the Port of Timaru 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. • Most non-indigenous species located in the Port are likely to have been introduced to New Zealand accidentally by international shipping. Approximately 69 % (11 of 16 species) of NIS in the Port of Timaru are likely to have been introduced in hull fouling assemblages, and 31 % (five species) could have been introduced by either ballast water or hull fouling vectors. • The predominance of hull fouling species in the introduced biota of the Port of Timaru (as opposed to ballast water introductions) is consistent with findings from similar port baseline studies overseas.
