-The hypothesis is proposed that mean level of heterozygosity is functionally related to rate of speciation in evolutionary phylads. Under this hypothesis, phylads which speciate more rapidly do so because of increased level of within-species genetic variability which is then available to conversion to species differences under appropriate ecological or environmental conditions. An important co...
Capoeta sevangi is a native species of the Cyprinidae family in the Caspian Sea basin (Arass River) and is ecologically and economically important. The main purpose of this study to investgate the relationship between absolute and relative fecundity with length, weight and age of this species in the Arass River and sampling was carried out from March to June 2012 using cast-net and gill-net. Th...

Myxosporeans are best known for the diseases they cause in commercially important fish species. Identification of myxosporeans at the species-level is mainly based on conventional methods. The 18S rRNA gene sequence of morphologically identified Myxobolus orissae infecting the gill lamellae of mrigal carp Cirrhinus mrigala was characterized in the present study. The plasmodia of M.orissae were ...
