MUSCAT, Oman — A new study from Sultan Qaboos University has identified the optimal water conditions needed to improve the survival of baby scalloped spiny lobsters (Panulirus homarus), offering new hope for sustainable lobster aquaculture in Oman and other coastal regions.
Published in the Journal of Agricultural and Marine Sciences, the study examined how temperature and salinity affect the survival of newly hatched lobster larvae — one of the most fragile and challenging stages in lobster farming.
Scalloped spiny lobster is considered a high-value seafood species with growing commercial potential. However, large-scale farming remains difficult because many larvae die during the earliest developmental stages, limiting hatchery success and increasing dependence on wild stocks.
To address this challenge, researchers tested different combinations of water temperatures (24°C, 27°C, and 30°C) and salinity levels (33, 35, and 37 ppt) to determine which conditions best support larval survival.
The results showed that larvae survived best at 24°C and 33 ppt salinity, remaining alive for up to 15 days. In contrast, survival rates declined sharply under warmer and saltier conditions, particularly at 30°C and 37 ppt.
The findings also revealed that temperature was the most influential environmental factor affecting larval survival, while salinity played a secondary but still significant role.
Researchers say the findings provide practical guidance for hatcheries and aquaculture producers seeking to improve larval survival and enhance the commercial viability of lobster farming.
The study could support the development of sustainable marine aquaculture in Oman by reducing harvesting pressure on wild lobster populations while strengthening local seafood production.
