APPENDIX 5 75
Empirical validation: Stage II
APPENDIX 5 PROJECT SUMMARY SHEET
Small Vessel Translocation of Key Threatening Species
Background Information Humans are transporting organisms and introducing them to new areas at an unprecedented rate. Introductions of non-native species are a serious threat to the diversity of plants and animals as they invade natural areas and replace native species. Hull fouling of yachts and fishing boats is contributing to the introduction and spread of non-native species to new sites. The 1999 black-striped mussel incursion in Darwin is a recent example. It was first introduced on the hull of an ocean-going yacht, and then spread to nearby marinas by other local yachts.
In southeast Australia, introduced marine pests such as the northern Pacific sea star, Asterias amurensis and Japanese kelp, Undaria pinnatifida are a serious threat. The northern pacific sea star is an important predator of scallops and mussels, while Japanese kelp fouls aquaculture facilities increasing operation costs and may hinder abalone and urchin divers. These “key threatening species” are spreading around the coastlines of southeast Australia. Recreational vessels may be inadvertently assisting this process.
What Are We Doing? The CSIRO is undertaking a study to assess the spread of these two introduced pests via small vessels from their main population centres in Tasmania and Victoria to other uninfected regions. Both Undaria and Asterias have a water borne and settled stage, therefore we are interested in collecting fouling and water samples. We will be taking samples from wet internal surfaces such as bilges and chain lockers, and from external surfaces such as the hull and keel, which will be scrapped using both rubber and metal scrapers while the boat is slipped.
We will be targeting recreational vessels, fishing vessels and aquaculture facilities that operate in areas where the northern Pacific sea star and/or Japanese kelp occur in high densities, such as the Derwent estuary.

20 Slime as dark green patches with yellow and/or brown coloured areas (advanced slime)
30 Weed as filaments up to 3 in. in length, projections up to 1/4 in. in height; or a flat network of filaments, green, yellow, or brown in colour
40 Calcareous fouling on edges, welded seams, corners, or as discrete patches covering flat areas roughly 9 to 10 in. in diameter

60 Area distribution of fouling by marine animals 1/4 in. in diameter or less; fouling does not completely cover or blank out surface
70 Fouling by marine animals 1/4 in diameter or less that completely covers surface in patches exceeding 9 to 10 in. in diameter; with radiating fringes of fouling growth
80 Dense fouling by marine animals with upright growth away from hull surface, calcareous shells appear clean or white in colour
90 Dense fouling by marine animals with upright growth away from hull surface, calcareous shells brown in colour or with slime and/or weed overlay
100 All forms of fouling present particularly soft sedentary animals without calcareous covering
** Fouling marine animals typically include tubeworms, barnacles, bryozoans, hydroids, sea squirts and molluscs.

APPENDIX 7 HULL SURFACE AREA CALCULATIONS
The wetted surface area (S) of ‘fast’ (e.g. racing yachts) hulls is given by Taylor’s formula:
IT LDCS � , [A1]
where C is a hull shape constant which varies between 2.56 and 2.59, DT is the vessel displacement (tonnes) and LI is the mean immersed length (in metres) usually interpreted as the waterline length. For ‘slower’ hulls with a fuller shape (e.g. recreational yachts and fishing vessels), the wetter surface area is given by Denny’s formula:
TDTLS V
P �� 7.1 [A2]
where LP is the length between perpendiculars (metres), T is the moulded mean draught (metres) and DV is the volume of displacement (cubic metres) (http://www.dynagen.co.za/eugene/hulls/).
In practise vessel owners, skippers and contractors rarely know the length between perpendiculars or the mean immersed length of their vessels. The wetted surface area of a hull is therefore calculated using the following approximate formula:
LTS 2� {A3]
where L is the vessel length (metres) and T is the mean draught (metres) (pers comm. C. Hewitt, MAFF).
