Movement patterns and home ranges of a pelagic carangid fish, Caranx crysos, around a petroleum platform complex.

The article presents a study on quantification of the home ranges and movement patterns of Caranx crysos, a pelagic carangid fish, in a petroleum platform complex. It states that the positions of 23 C. crysos, which were implanted with acoustic transmitters through surgery, were localized in the petroleum platform in the Gulf of Mexico with the use of a hydrophone network. It adds that the fish were tracked for 23 days in August 2005 and the home ranges of each fish were calculated throughout the study period. After tracking them, it shows that most fish prefer a discrete area in the platform complex. It also notes that more transmissions were detected during the day. The results show that the schooling of the pelagic species determines a home range within the structure's vicinity.
