length-weight relationships were estimated for three gobiid species of iran. significant length-weight relationships with high correlation coefficient were found for all species from eight localities. the value of the parameter b varied between 2.196-2.498 for boleophthalmus dussumieri (valenciennes, 1837); 2.554 to 3.460 for periophthalmus waltoni (koumans, 1955) and 2.316 to 2.920 for scartel...

in order to determine the age structure, growth, and length-weight relationship of the mudskipper, periophthalmus waltoni, from coastal mudflats of qeshm island, soroo and bandar-pol, in hormuzgan province, iran, we collected 192 individuals in february 2007. age was determined using the second pectoral radial bone and year class was based on length-frequency distributions. growth was descr...

considerable amounts of different pollutants, especially crude oils, are present in the persian gulf and its northern region, so biomonitoring the effect of these pollutants on its biota is necessary. ethoxyresorufin o-deethylase (erod), gluthathione s-transferase (gst) and catalase (cat) activity were measured from biochemical level in the gills of mudskipper periophthalmus waltoni collected f...

the present study provides the first large scale survey on intertidal ichthyofauna along the coastline of iran from gawater bay (border of pakistan) in the gulf of oman to arvandkenar (border of iraq) in the persian gulf. this study was carried out in the years 2005-2006 at 15 stations, including mangrove, mudflat and rocky shores. specimens were collected at low tide from tide pools, using chl...

1. The routine oxygen consumption by Periophthalmus cantonensis and Boleophthalmus chinensis in water increased geometrically, whereas that in air increased logarithmically with temperature. At temperatures of more than 20 degrees C the oxygen uptake of both species was greater in water than in air. 2. When the fishes were able freely to select either an aquatic or terrestrial habitat, the tota...
