Abstract
The International Maritime Organization (IMO) has established guidelines to face the problem of biological contamination in coastal areas generated by the ballast water vector. Among these guidelines, several models have been established to assess the risk of introducing species into new areas, including: discharge frequency (C1), ballast water discharged in port volumes (C2); and, environmental similarity between the port of origin with the receiving port (C3). Based on the IMO model and the information contained in the Ballast Water Notification forms, sent to the General Maritime Directorate in compliance with Resolution 477/2012, the risk level for Tumaco and Buenaventura ports was established. During 2015, ballast water with the highest shedding frequency in the port of Tumaco came from Long Beach (USA), being 13.4 % of the total discharge (C1). For the port of Buenaventura, this percentage was represented by waters from Manta (Ecuador) and Puerto Caldera (Costa Rica), with percentages of 19.56 % and 18.47 %, respectively. Tumaco imported around 310 062 m3 of ballast water and Buenaventura about 132,294 m3, which corresponded to 176 unloaded tanks, coming from 14 ports with origin in twelve countries for Tumaco and 184 tanks from 12 ports of origin in six countries for Buenaventura (C2). Regarding the environmental similarity (C3), it could be deduced that San José-Guatemala (0.99) and Buenaventura-Colombia (0.99), presented greater similarity with the port of Tumaco, followed by Talara-Peru (0.98), La Pampilla- Peru (0.89) and Los Angeles-USA (0.89); while for Buenaventura the greatest similarity was presented by the ports located in Puerto Quetzal-Guatemala (0.99) and Caldera-Costa Rica (0.97).
