Abstarct: Abstarct: Mudskipper species diversity in the Khur –e- Abee protected area in the coastal areas of the Persian Gulf in Hormozgan Province was studied monthly. Sampling was done from March 2011 to February 2012 is 56º 24' 58” E, 27º 11' 28” N geographical position. 730 specimens belonging to 3 species and 1 family were catched. The fish specimens were captured by hand. Three species were identified; Boleophthalmus dussumieri, Scartelaos tenuis and Periophthalmus waltoni. The monthly sampling of mudskipper species composition showed that S. tenuis (45.75%), P. waltoni (30.48%) and B. dussumieri (26/02%) were first, second and the third in abundance respectively. Shannon species diversity (1.09), Simpson index (0.62) and Peilo species index (0.99) were highest in October. Margalef species richness (0.62) was highest in December.

Survey on fecundity of mudskipper Scartelaos tenuis from Abi Estuaries and Azini were carried out from March to April 2010. Data were sampled by hand based on simple random sampling. A totally 219 mudskipper were collected, throughout 113 individual were caught from Abi Estuaries (93 female, 20 male) and 106 invidiual from Azini Estuarie (83 femal, 23 male). The sex ratio of female to male was observed 1:0.24 and it was significantly different from the theoretical 1male:1female sex ratio (P>0.05). Mean total length were calculated 16.32±2.14 cm for female in Bandar Pol and 15.50±2.11 cm for male, and mean length 16.19±2.27 cm for femal and 17.26±1.9 cm for male in Tiab. The result showed no significant differences between mudskipper lengths in two areas (P>0.05). The more frequent length classes were calculated 15-16 cm in Bandar Pol and 18-19 cm in Tiab.The length – weight relationships were estimated as W= 0.0016TL2.7245 for female and W= 0.0138TL2.6523 for male, and the result showed isometric growth. Mean absolute fecundity were estimated 4147±1045 in Bandar pol and 3707±983 in Tiab area, there are no significant differences between fecundity in two areas (P>0.05). The relationship between fecundity-total length were calculated as Fecundity=36.17TL1.6412. The average eggs diameter were calculated 796±144mm in Bandar Pol and 737±137mm in Tiab. The relationship between egg diameter and gonad weight carried out as OD=0.0009GW-0.2167 (R2=0.4728).
