grading science and grading equipment for many kinds of sea products are growing rapidly in developed communities and variety of grading equipment can be found in most of the large fishery units. computer vision has the potential to be used as a precise method for recognition and assessment of apparent characteristics. in this study, machine vision technology was used to sort fish based on spec...

this study aimed to evaluate the effects of prebiotic immunoster on growth and nutrition performance, survival rate and body composition and intestine bacterial flora of common carp (cyprinus carpio) fingerlings. 15 fish with initial weight 12 + 1 g distributed in 12 tanks and fed with different dietary levels of prebiotic (0.5, 1.5, 2.5 g/kg diet) for 60 days. at the end of experimental period...

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...

Background: FishBase.org is an on-line database of fish related data that has been cited over 1500 times in the fisheries literature. Length-weight relationships in fish traditionally employ the model, W(L) = aL b , where L is length and W is weight. Parameters a and b are catalogued by FishBase for a large number of sources and species. FishBase.org detects outliers in a plot of log(a) vs. b t...

this research was conducted to study the length-weight and length-length relationships and condition factor of six cyprinid fish species viz. alburnus atropatena , barbus lacerta , capoeta capoeta , carrasius gibelio , romanogobio macropterus and pseudorasbora parva from zarrineh river (urmia lake basin, iran). a total of 188 specimens ranging from 2.9 to 21.4cm in total length and 0.22 to 176g...

1. A study of the length, total weight and weight per cm of the small intestine of virgin, pregnant and lactating rats has provided evidence for an increase in intestinal surface area in pregnancy and lactation. 2. Because of such alterations in morphology of the gut the absorption, in vivo, of the substrates studied, glucose and glycine, has been expressed in terms of amount transferred per lo...
