Boleophthalmus Dussumieri

Background: The fishes of family Gobiidae are one of the least studied fishes, especially for otolith structure. The otoliths were possess species specific features. Hence, traits of sagittal otolith of gobid species studied. Methods: Five gobid species Odontamblyopus roseus (Valenciennes, 1837), Trypauchen vagina (Bloch and Schneider, 1801), Glossogobius giuris (Hamilton, 1822), Parachaeturichthys polynema (Bleeker, 1853) and Boleophthalmus dussumieri (Valenciennes, 1837) were investigated by three methods including morphological, shape indices and step wise discriminant function analysis (SDFA). Result: Interrelationship between shape indices investigated, at 95% level of confidence (P less than 0.05), revealed that perimeter of P. polynema and area of T. vagina have isometric growth with their length (b = 3.0071, 2.90, respectively) and otolith area of B. dussumieri have positive allometric growth (b = 4.23077). SDFA, based on otolith morphometry, discriminated species up with 97.18% accuracy. Hence, the results of present investigation can be used for discrimination of the species and as a tool in predicting fish size from the otoliths and in calculating the biomass of these less studied fish species.

Abstract Background Mudskipper is from the Gobiidae family and from the subfamily Oxudercinae. Mudskipper contains four main genera Boleophthalmus, Periophthalmodon, Periophthalmus, and Scartelaos. The aim of this research identification of bacterial agent (Marine bacteria) mudskippers Boleophthalmus dussumieri on the Shores of the northern intertidal areas of the Persian Gulf (Abadan, Hendijan and Bahrekan), Iran. The mud sediment and water samples (at the depth of one m), and mudskipper fish samples (near shore at the intertidal) were collected from Abadan, Hendijan and Bahrekan in northern coasts of the Persian Gulf, Iran. Results A total of 80 aerobic bacteria marine (from the intestines of mudskipper, seawater, and muddy sediments ) was identified by biochemical tests and 16S rRNA gene sequence analysis. The bacteria's (Marine bacteria) [Eubacterium] tenue strain DSM 20695, Praclostridium bifermentans strain JCM 1386 and Vibrio hyugaensis strain 090810a was first identified in the northern intertidal areas of Persian Gulf, Iran. Conclusions Bacteria compete with other organisms to get oxygen to the surface layers of the flower bed. They give that the bacterial species common to the fish intestines and sediments is high and due to fish feeding of sediment it can be concluded that the species present in the fish intestine in the present study may be a function of substrate species that needs further studies to prove this.
