    Abstract
    Bioinvasions are generally taken note of only when their impacts are felt. The impacts directly experienced by the society can be economical (loss of fishery or water as a resource) and human health related (for example, cholera epidemic, toxicity due to micro algal contamination). The ecological impacts, on the other hand, are complex and dependent on the interaction between the invader and the native community. The cost of invasion is generally related to how early one responds to the problem, and it increases with the lapse of time. Many cases of marine bioinvasion have been reported and their harmful effects on the ecosystem and human health have been documented. This paper provides an overview of the factors that influence the success of invasive alien species. Translocation of organisms through ships' ballast water is considered to be one of the important issues threatening the naturally evolved biodiversity, and consequences of such invasions are being realized increasingly in the recent years. International efforts underway to address this issue are brought out in this paper.
