More than 70% of the earth is covered by oceans and major seas and there are more than 1.6 million kilometres of coastline. Yet our marine world is under threat: the most insidious is the one posed by marine invasive species. This booklet does not present new or primary information, but rather a synthesis of current issues and trends, including several examples of some of the worst marine invasive species, their spread and impact.

Más del 70% de la tierra está cubierta por océanos y mares mayores y hay más de 1,6 millones de kilómetros de costa. Sin embargo, nuestro mundo marino está en peligro: la peor amenaza es la de las especies marinas invasoras. El folleto no presenta información nueva o primordial, sino más bien una síntesis de las cuestiones y tendencias actuales, incluyendo varios ejemplos de algunas de las peores especies marinas invasoras, su propagación e impacto.

Biological invasion, an issue of growing importance due to the significant increase in international transportation and trade, can disturb the balance of local ecosystems and even destroy them. This collection of papers presented at the International Conference on Assessment and Control of Biological Invasion Risks held in August 2004 at Yokohama National University discusses risk assessment, risk management and eradication.
