| Summary: | The aim of this research was to identify and isolate the fatty acids composition of Nerita
textiles in intertidal area of Chabahar Bay, and also to explore the seasonal changes of fatty
acid content in Nerita textiles. GC/MS resulted thirteen fatty acids, that saturated fatty acids
(SFA) of palmitic acid (16:0) was the most abundant category of fatty acid obtained in total
lipids. There were no significant differences in total saturated fatty acids between different
seasons. No significant differences were also observed in total unsaturated fatty acids between
different seasons. The majority of unsaturated fatty acid reached their maximum levels during
winter, while saturated acids reached their maximum levels in summer. Saturated acids were
more than unsaturated fatty acids. Statistical analysis showed the positive significant
correlation between temperature and saturated fatty acids and a negative significant
correlation between temperature and unsaturated fatty acids. Biomarker fatty acids revealed
that diet of Nerita textiles probably includes phytoplankton, zooplankton, detritus, bacteria,
diatoms, red and brown algae. The results showed that meat quality indicated n-6/n-3 ratio in
the range of 1.9 to 4.3. |
