The Mussel Musculista Senhousia in Australasia; Another Aggressive Alien Highlights the Need for Quarantine at Ports
Abstract:During the last 6 years the mussel Musculista senhousia (Benson in Cantor, 1842) has become established in New Zealand and Australia. Dispersal has been particularly rapid from the site of first arrival at Auckland, New Zealand. Population densities in both countries are presently less than the maxima reported for adults from eastern Asia, its original home. Besides documenting the separate invasions, this paper evaluates the threat this mollusk poses to existing shellfisheries, especially oyster farms and hatcheries. Although M. senhousia may pose no immediate threat to the oyster industry, introduction of further alien marine organisms by way of shipping may well seriously jeopardize such mariculture enterprises. Legislation to prevent accidental entry of foreign marine organisms through ports needs to be enacted.
