Marine biofouling invertebrates on the hull of the ship ARC “20 de Julio”Abstract
A bordo del buque ARC “20 de Julio” se realizó la Primera Expedición Científica a la Antártica entre diciembre del 2014 y abril del 2015. Antes y después del zarpe, se colectaron mediante buceo, muestras de organismos marinos adheridos a las estructuras externas sumergidas del buque. Los invertebrados marinos colectados se identificaron taxonómicamente y se estableció su condición de origen (especies nativas, invasoras o criptogénicas). La fauna marina estuvo representada por los filos artrópodo, molusco, anélido y porífera. La familia Balanidae aportó el mayor número de individuos, conformada por las especies Balanus amphitrite, Balanus reticulatus y Balanus eburneus, seguida de la familia Mitilidae, representada por especies como Brachidontes domingensis y Brachidontes exustus. Las especies identificadas en el estudio, se reconocen como miembros comunes de las comunidades bioncrustantes alrededor del mundo y algunas han sido catalogadas como introducidas para la bahía de Cartagena. La presente investigación se desarrolló como base de futuros estudios sobre organismos incrustantes en el puerto de Cartagena, tendientes a minimizar, controlar o evitar efectos negativos sobre las actividades portuarias y navieras, y la expansión de especies marinas a nuevas áreas marino-costeras.Colombia’s First Scientific Expedition to the Antarctic was performed between December of 2014 and April of 2015 on board the ship ARC “20 Julio”. Before and after departure, divers collected samples of marine organisms adhering to ship´s submerged external structures. The marine invertebrates were taxonomically identified and the condition of origin (native species, invasive or cryptogenic) was established. The marine fauna was represented by phylum arthropod, mollusk, annelid and porifera. The Balanidae family contributed the largest number of individuals, consisting of the species Balanus Amphitrite, Balanus reticulatus and Balanus eburneus, followed Mitilidae family, represented by species such as Brachidontes domingensis and Brachidontes exustus. The species identified are recognized as common members of fouling communities around the world and some have been listed as introduced to the Cartagena Bay. This research is developed as a basis for future studies of fouling organisms in the port of Cartagena, to minimize, control or prevent negative effects on port and shipping activities and the expansion of marine species into new marine coastal areas.
