kutum, rutilus frisii kutum, is an commercially important fish in the caspian sea. the fish enters the rivers leading to the caspian sea for spawning. one of these rivers is shiroud river. in the artificial propagation process of kutum, different factors are involved in quality and quantity of female broods eggs and also in the best temperature and migration time for spawning. the influence of ...

we collected the specimens of turcinoemacheilus hafezi throughout the spawning season (january to july, 2012) in beshar river (south-west iran) and investigated its age, growth, and reproductive characteristics. the maximum age was 2 + years. total length and weight of the specimens ranged from 29 to 61 mm and 0.17 to 1.39 g, respectively. length-weight relationship was estimated as w = 3e-05tl...

owing to reduction of sturgeon stocks in various water bodies, artificial propagation has become significantly important for stock restoration and appropriate broodstock selection is vital in this process. selection of suitable broodstocks may influence the quality and quantity of obtained eggs and larva. the present study aimed to examine correlation between some morphometric and reproductive ...

cobitis faridpaki cobitis faridpaki (mousavi-sabet, vasil'eva, vatandoust and vasil'ev, 2011) is found in streams of the siahrud river in the southeastern caspian sea basin, and this is the first report on reproductive parameters of the newly described endemic loach. reproductive conditions are key parameters of fish populations, and their assessment is very important for endemic fishes. to stu...

Fecundity of guchibaim, Mastacembelus pancalus was described based on 100 samples collected from the experimental ponds of the Field Laboratory Complex, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh during the period from May to July 2007. The surveyed sample ranged from 115 to165mm in total length and 6.97±0.44 to 10.52±0.22g in average body weight. The ovary weight of t...

This study was carried out to determine population structure, growth and reproduction properties of barbel. A total of 198 individuals were sampled. Ages of samples were found between I and VI years, fork lengths between 4.3 and 16.6 cm and total weights between 1.2 and 65.8 g. Length-weight relationship was calculated as W=0.0146×L2.934. Munro’s phi prime index was estimated as 1.95, L∞ ...
