Nutritional value of Chabahar Bay (Oman Sea) Sargassum lentifollium before and after monsoon season

The proximate composition of brown seaweed Sargassum lentifollium was investigated in
this study along with analysis of some physicochemical parameters of Chabahar Bay water. The
relationship between the nutritive components of this species and environmental parameters was
established. Crude protein content varied from 8.05±1.15% of dry weight to 12.29±1.10%,
carbohydrate from 31.11±2.03% to 25.11±2.13%, humidity from 15.21±1.00% to 19.22±1.11%
with differences significantly before and after monsoon seasons, respectively while ash content
varied from 26.11±2.43% to 24.11±1.40%, total fat from 2.11±0.43 % to 1.80±0.40% , total fiber
from 10.34±2.21% to 11.84±0.33% and astaxantin content (ppm) from 104.11±1.00 to
97.20±1.18 before and after monsoon season respectively without any significant
differences(P>0.05). Regarding to physicochemical parameters of sea water, the result showed there
are differences between salinity, dissolved oxygen, water temperature, nitrate, phosphate,
chlorophyll a and c before and after monsoon season significantly while there are not in pH, silicate
and chlorophyll b. Statistical analysis computed among the environmental and biochemical
parameters suggested the potential role played by the abiotic parameters on biosynthetic pathways
of seaweed.
