Vessel biofouling represents a significant pathway for the introduction of non-indigenous species (NIS) into New Zealand’s marine ecosystems and subsequent spread.
Sea chests are large recesses in the hull that enable the efficient intake of water for internal seawater systems (e.g. engine cooling, ballast water, air conditioning, fire-fighting systems). These niche areas are found on large international and domestic vessels which operate in New Zealand waters. Sea chests have been found to harbour dense and diverse biofouling assemblages which are generally inaccessible for inspection or treatment by divers. Marine Growth Prevention Systems (MGPS) are a preventive tool used to minimise biofouling growth in sea chests. While MGPS may be sufficient to reduce biofouling for operational purposes, independent evidence regarding the efficacy of MGPS to meet biosecurity objectives are required.
The objective of this project is to assess the general effectiveness of recommended dosing for MGPS to prevent biofouling accumulation, identify the factors that influence MGPS efficacy, and outline a set of best practice maintenance principles regarding MGPS use.
