摘要

Both species form an important part of fisheries landings in the southern Arabian Gulf, where they are mainly caught with dome-shaped wire traps that have a hexagonal mesh of approximately 3.5 cm in diameter. Traps are either set individually or in strings from traditional wooden dhows, sets are made to a maximum depth of 40 m, and vessels fish an average of 210 traps each. Collection of catch-and-effort data for the fisheries of the Emirate of Abu Dhabi in the United Arab Emirates was initiated in 2001. However, many species, including D. pictum and L. nebulosus, are recorded to the family level, and therefore the use of statistical catch-at-age methods can not be used for conducting assessments at the species level. Landings of haemulids (predominantly D. pictum) and lethrinids (predominantly L. nebulosus), totaled 719 and 2911 metric tons, respectively, in the Emirate of Abu Dhabi during 2003 (Grandcourt et al.1). Despite the limited time scale for which catch and effort data are available, there has been an overall increase in fishing effort and catches since 2001.
