Abstract: Fluctuating asymmetry in otolith dimensions reflect the stress from environmental conditions such as temperature stress, nutritional stress and pollution. Sagittal otolith characters such as length, width, area and perimeter of
Sargocentron spiniferum (sabre squirrelfish) from Shalateen fishing area were investigated.
S. spiniferum samples were divided into four-total length groups. All length groups were examined for asymmetry values in the four otolith characteristic, the level of asymmetry of otolith width was higher than of other otolith characters and the highest asymmetry values were found in the group II (240-309 mm). The lowest asymmetry values in area and perimeter otolith characters were found in the first length group (170-239 mm) and the third one (310-379 mm). The asymmetry in these otolith characters may be a result of the stress from environmental conditions in Shalateen, Red Sea coast of Egypt.
