الملخص الإنجليزي
Spiny lobster is one of the highest-priced seafood worldwide. Its fishery contributes well to the
country's income and is considered one of the important export items to other countries. However, its annual
catch declined sharply. Studying the stock is important for proper fishery management because stock res
ponds differently to overexploitation and adaptation, therefore different stocks need different conservation
plan. In this study, the genetic diversity and population differentiation of 50 P. homarus (the most present
spiny lobster subspecies in Oman) from two regions (Al-Ashkharah and Masirah) of Al Sharqyah gover
norate were studied using 49 microsatellite markers. The results showed that P. homarus from the two sites
are genetically similar based on low Fst (0.009), AMOVA test (1% variation). In addition, they are admixed
as it is shown by DAPC (Discriminate Analysis of Principal Component) and by the phylogenetic tree. In
conclusion, P. homarus from the two sites can be considered as a single stock, therefore the same fishery
management and conservation strategy can be used to manage the spiny lobster fishery in Al Sharqyah go
vernorate. More studies with a larger sample size are necessary to support our findings.
