grey mullet (mugil cephalus) is an important food fish species in the, mugilidae which is able to adapt in a wide range of salinities and temperatures and is suitable for introduction of the species to freshwater, brackish, and brine waters for aquaculture. this study was implemented to determine appropriate normative of stocking density and initial weight ofmugil cephalus and also evaluate eff...
An examination of urban rural links in each location requires the analysis of streams linking urban and rural settlements. Such links under the heading of "flow of space" are embodied in the framework of a network approach and include flows of capital, persons, goods, information, innovation, technology, and so on. These flows include a process that, in appropriate conditions They can bring tog...
in recent years, rangelands have been regarded as potential carbon sinks. one of the most widely suggested options to sequester more c in rangelands is the restoration of the degraded rangelands through grazing the exclusion. in present study, the effects of exclusion on the carbon sequestration of gomishan rangelands were investigated. three transects were established in a key area inside and ...
due to the lack of specified linage and parentage information from exotic broodstocks of litopenaeus vannamei shrimp, in iran and multiple breeding of closed broodstock populations, also concern about the low level of genetic diversity and accumulated inbreeding and in order to comparison of the genetic variability indices and analysis of the genetic differentiation, total of 30 samples from bo...
common carp ( cyprinus carpio ) population has been declined in the caspian sea in the recent years, mainly due to human manipulation. this valuable species needs to be protected in the caspian sea. considering the commercial value of common carp, its rehabilitation program has been established. in the present study, 8 microsatellite loci were used to assess genetic variation and population str...
Regarding climate change, it is important to determine the most suitable time for starting its cultivation on the site of Gomishan shrimp. For this purpose, in range of air temperature (15-25°C), 21°C was chosen as the base temperature for Gomishan area. This experiment was conducted in 8 terrestrial ponds that were different of density (350000, 182000, 100000 ind/he and time of stocking; 18 Ju...
