The aim of the present study was to determine the presence of p,p’-DDT and its metabolites (p,p’DDE and p,p’-DDD) and ã-HCH and PCBs in the muscle of gray mullet, Mugil cephalus collected from Cuddalore coast of Bay of Bengal during the period from June 2009 to January 2010. Polychlorinated hydrocarbons are convenient indicators of environmental pollution. The analyses were carried out using th...

plants showing root and crown rot were collected from 48 bean fields in the khuzestan and markazi provinces during 2005-2006. using specific primers (fsphr/fsphf) for these forma specialis, three isolates were identified as f.s. f.sp. phaseoli. conidial suspension of one of these isolates were irradiated (in a 60co- gamma cell with activity of 2500 curi and 0.38 grey per second dose rates) with...

This study examines features such as the population structure, growth and reproduction of the pearl mullet captured in the Lake Ercek. Between the dates January 2008 and January 2010 a total number of 527 individual were sampled through using trammel net and mesh size of 20,22 and 24 mm of fish net. The fork length, total and gonad weight, sex and fecundity of the pearl mullet which were captur...

three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in finike bay for red mullet (mullus barbatus l., 1758). the sampling program was arranged during february to may 2012. holt (1963) method was used for selectivity of trammel nets. red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...
