some 190 specimens of sefidrud loach, oxynoemacheilus bergianus , were collected from aras river (northwestern iran) and age, size, and some biological characteristics of the samples were investigated from march to july 2013. the maximum age was 3 + years. the specimens ranged in size from 42 to 64mm for males and 45 to 61mm for females in total length, weighing from 0.62 to 2.03g for males and...

the research carried out the length-length relationships (llr), length-weight relationship (lwr) and condition factor of nine freshwater small indigenous species viz. g. giuris, e . danricus, m . pancalus , l . guntea, c. fasciatus, p. sophore, h .  fossilis, c .   punctatus and m. cavasius from the waterbodies of nageshwari, bangladesh. relationships among different body lenght parameters of e...

length-weight relationship and condition factor were investigated in seven fish species, including barbus cyri , capoeta gracilis , alburnoides eichwaldi , acanthalbarnus microlepis , ponticola cyrius , cobitis keyvani and oxynemacheilus bergianus from totkabon river. a total of 570 specimens ranging from 25.90 to 146.97 mm in total length and 0.1 to 260.3 g in total weight were collected. base...

we collected silver bream blicca bjoerkna from march to july 2013 from aras dam lake (north-west of iran) and investigated its age, size, and some biological characteristics. the maximum age was 5 + years. the total length and weight of specimens ranged 137-278 mm and 26-247 g for male and 134-282 mm and 26-289 g for female, respectively. length-weight relationship was estimated as w = 1e-06tl ...

length weight relationships of vimba vimba persa were studied. for this purpose 174 fish samples were collected by gill nets, beach seine and purse seine from march through june 2008 at two guilan fisheries catch stations of guilan located in anzali- kiyashahr regions. samples were immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, we...

this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of  two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...

the effects of weight and length of barbus grypus broodstock on fingerlings reproductive characteristics and growth were investigated. we chose three female treatments  including weight and length groups (1) 2212.5±479g,  62.68±6.7cm, (2) 4518±780g,  79.12±4.36cm  and (3) 7712.5±1171g, 92.62±3.13cm. the same male broodstock were used for all the treatments with the weight and length size of 140...

the present study describes the length-weight relationship (lwr), length-length relationship (llr) and condition factor of the wild population of the shrimp macrobrachium macrobrachion from the rivers of côte d’ivoire (west africa). samples were randomly collected from small-scale shrimp fisheries using bamboo traps. of the thirteen analyzed morphometrics characters, only the second pleura widt...
