The aim of the present study was to investigate the population dynamics of Liza klunzingeri, in Hormouzgan province waters located in northern coasts of the Persian Gulf and Oman Sea. This study was carried out from October 2007 to September 2008. samples were collected from commercial stake traps. The relationship between weight and fork length was found to be W= 0.0214 F.L2.8233 suggesting ...

This experiment was conducted to evaluate the efficacy of different levels of Echinacea (Echinacea purpurea) methanol extract on the growth performances (final weight (FW), daily growth ratio (DGR), feed conversion rate (FCR), voluntary feed intake (VFI) and protein efficiency ratio (PER) and some of hematological parameters (hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) and white blo...

It is generally accepted that feed intake and growth (gain) are the most important economic components when calculating profitability in a growth test or feedlot. We developed a single post-weaning growth (feedlot) index based on the economic values of different components. Variance components, heritabilities and genetic correlations for and between initial weight (IW), final weight (FW), feed ...

This investigation was carried out to determine the effects of gamma radiation on germination and physiological characteristics of wheat seedlings. Two wheat genotypes (Roshan and T-65-58-8) were irradiated with 100, 200, 300 and 400 Gy. The results showed that MGT (Mean Germination Time), root and shoot length, and seedling dry weight decreased with increasing radiation doses but final germina...

Lawns achieve environmental, functional, and aesthetical roles in urban environments. The objectives of this research were to assess the effect different salinity levels on Trichoderma isolates study spp. perennial ryegrass under salinity. T. harzianum (ThLem2017-01) atroviride (TaDP2019-01) had a higher mycelium growth rate than (TaDP2019-02) when low. In contrast, isolate at high superior res...

Let α be a formal variable and Fw be a weighted species of structures (class of structures closed under weight-preserving isomorphisms) of the form Fw = E(F c w), where E and F c w respectively denote the species of sets and of connected Fw-structures. Multiplying by α the weight of each F c wstructure yields the species Fw(α) = E(F c αw). We introduce a “universal” virtual weighted species, Λ,...

Common carp (Cyprinus carpio) represents one of the most economically important fish species in the Caspian Sea. In this study, growth and mortality parameters among population of common carp was investigated. Sampling was carried out weekly, using beach seine in the south of the Caspian Sea from October 2006 to September 2007. As a contribution to elaborating management programs for common car...
