Basic assessment of Portunus segnis (Forskål, 1775) – A baseline for stock management in the Western Arabian Gulf
Portunus segnis (Forskål, 1775) is the representative species of the Portunus pelagicus (Linnaeus, 1758) complex described as inhabiting the Arabian Gulf. It represents one of the most important decapod resources within this semi-enclosed hyper-saline and hyper-thermal marine eco-region. Previous bi...
