Intentional Pathway

Intentional introduction of IAS happens when these species are intentionally introduced as sources of food, medicine, ornaments and biological controls. They can also be introduced for the purposes agriculture, forestry, horticulture and fisheries. Besides, household pets or aquatic species can also be released into the wild when it is of no value to humans. Human transportation and trade are hence common forms of vectors by which IAS leverage on to establish and spread in an ecosystem.
