Survey of biodiversity and planktonic stage of demersal Fishes in coastal waters of Hengam island (strait of hormoz)

The larval stages of demersal Fish were sampled from coastal waters of Hengam Island (Strait of Hormuz). Sampling was conducted from late winter 2012 to early autumn 2013 seasonally. The larvae were collected with plankton net 300 μm mesh size using oblique towing method from near bottom to sea surface in 6 stations with three replicates. A total of 6832 pieces of larvae were collected in the families including (Gobiesocidae, Bothidae, Blenniidae, Tripeterygiidae, Soleidae ) included 20% of total catch. Tottaly 4 species were identified including Pseudorhombus sp. of family Bothidae , Omobranchus sp. and Parablennius thysanius of family Blenniidae , Helcogramma steinitzi of family Tripeterygiidae. The highest abundance of fish larvae (3.59 ind/100m3) found in the autumn and the lowest frequency (0.34 ind/100m3) calculated in the summer. The results of the ANOVA showed a significant difference (p
