The survey of fish larvae assemblage variation was done in 2013 seasonally at the coastal
areas of Southeastern side of Chabahar Bay. Sampling was done in 3 stations at day and night
periods by a Bongo-Net with 300Î¼ of mesh size. 29 families were identified. Clupeidae,
Gobiidae and Blenniidae were dominant with more than 50% relative abundance. The PCA
result was shown there were two separated groups among day and night fish larval
assemblages. Blenniidae ØScombridae and Clupeidae in day times, Clupeidae ØGobiidae and
Sparidae in night times were more dominant among different families. Station 1 had more
fish larvae abundance in autumn in nights and days (54.77 and 79.67 larvae per 10 meter).
The average of Shannon index was (0.54 Â±0.88 and 0.63Â± 0.97) in days and nights
respectively.Significant increase of larval abundance at station 3 in nights could be due to
reduced vessel traffic.
