摘要

Many of the fish populations in the Arabian Gulf have been heavily exploited (Samuel et al., 1987), and fishing effort may have already been above optimum levels for most demersal species (Siddeek et al., 1999). The expansion of the fishing fleet of the United Arab Emirates and the lack of appropriate data on most stocks underscore the need to assess the fisheries resources of the region. The goal of this study was to evaluate the status of D. pictum and L. nebulosus and to provide biological reference points and other pertinent information required for management. Specific objectives included establishing key demographic parameters by using validated age estimates, identifying reproductive characteristics and conducting yield-per-recruit analyses for the selected study species.
