Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...

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...

The Wisconsin glaciation was started a approximately 125,000 years ago and reached its lowest extend between 20,000 to 21,000 years ago during which the sea level fell 120 to 130 meter. At the end of the ice age, about 18,000 years ago, the sea level increased and reached its present level about 5,000 years ago. The Persian Gulf was exposed in the last glacial moment (LGM). After this moment, t...

The reproductive biology of the Iranian cichlid, Iranocichla hormuzensis Coad, 1988, was investigated for 13 consecutive months in lower Mehran River, from August 2008 through August 2009. Four hundred and eighty six individuals (252 males and 234 females) were captured using a seine net (5 mm mesh size). The observed sex ratio was 1M: 0.93F (χ², df = 1, P = 0.414). Mean ± SD of total length (T...

longtail tuna (thunnus tonggol) is one of the most important and commercial species in the persian gulf and oman sea. in order to come up with the responsible fishing pattern, there was a need to identify some of the biological characteristics and population dynamic parameters. data were collected randomly from six major artisanal fish-landing sites hassineh, kong, bandar abbas, salakh, sirik a...

with regard to bycatch problem, this is the first study of the shrimp trawl bycatch in different depth variation in hormuzgan coastal waters. samples were collected during shrimp season in october 2011 and november 2012. the study area was divided into two regions: hormuz-keshtisoukhte (56°, 27ʹ e/27°, 07ʹ n) to (56°, 18ʹ e/27°, 06ʹ n) and keshtisoukhte-toola (56°, 18ʹ e/27°, 06ʹ n) to (55°, 58...

The objective of this study was determining the heavy metal contents in sediment along the coastlines of Hormuzgan province. Sediment constitutes are important part of aquatic ecosystems. They provide habitat for benthic organisms and could be a significant sink as well as a potential source of contaminants. Three sources of heavy metals pollution in this area are industry, natural mineral...
