DELGADILLO-GARZON, Óscar. FISHES AND MOBILE MACROINVERTEBRATES OF ARTIFICIAL HABITATS IN TAGANGA BAY, COLOMBIAN CARIBBEAN. Bol. Invest. Mar. Cost. [online]. 2009, vol.38, n.1, pp.197-204. ISSN 0122-9761.

Fishes and macroinvertebrates associated to two types of artificial habitats deployed in Taganga Bay were assessed by stationary visual census to compare these assemblages. Forty-one species of fishes and nine macroinvertebrates were observed in eleven visual censuses. The distribution patterns depicted in abundance and richness between the two types of habitats used (concrete blocks vs. artificial shelters), were a possible response to dissimilarities in their location and number of visual census. A relative high fish richness and diversity were found in these artificial habitats, in comparison to other artificial structures in Colombia, probably owing to their proximity with heterogeneous natural habitats. The use of complex artificial habitats could have potential useful to conserve, restore and manage some marine resources supported in planned researches in this area.
