Fermented soybean meal (FSM) is an important feed material that can replace fish to solve the shortage of animal protein. To improve utilization FSM, we optimized co-fermentation conditions using Bacillus subtilis and Enterococcus faecium studied effects replacing with different proportions FSM on serum antioxidant indices gut microbiota (GM) composition crucian carp (Carassius auratus). Our re...

The activity of 5-aminolevulinic acid dehydratase (ALA-D) in the blood of crucian carp, Carassius auratus langsdorfiii, was measured under a variety of lead exposure conditions. A three-week exposure of crucian carp to water lead concentrations of 3, 10, and 30 ppb inhibited their ALA-D activities with increasing water lead concentrations. When crucian carp were exposed to a water lead concentr...

Native and exotic fishes were collected from 29 sites across coastal and inland New South Wales, Queensland and Victoria, using a range of techniques, to infer the distribution of Bothriocephalus acheilognathi (Cestoda: Pseudophyllidea) and the host species in which it occurs. The distribution of B. acheilognathi was determined by that of its principal host, carp, Cyprinus carpio; it did not oc...

Prussian carp (Carassius gibelio) are one of the most noxious non-native species in Eurasia. Recently, Prussian carp, a non-native freshwater fish species, were genetically confirmed in Alberta, Canada and have been rapidly expanding their range in North America since establishment. Given their rapid range expansion, there is an increasing need to determine how Prussian carp may impact native s...

Ten years ago, very little was known about the genetics of most of the cyprinid species of interest to aquaculture in Asia, for example the Chinese carps, silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis) and grass carp (Ctenopharyngodon idella); Indian major carps, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosus); and the silver barb (Barbo...

Quantum dots (QDs) interaction with living organisms is of central interest due to their various biological and medical applications. One of the most important mechanisms proposed for various silicon nanoparticle-mediated toxicity is oxidative stress. We investigated the basic processes of cellular damage by oxidative stress and tissue injury following QD accumulation in the gibel carp liver af...

This study aimed to determine the length-weight relationship and condition factor of Prussian carp (Carassius gibelio, Bloch, 1782) from Asi River. Samples were collected by 12-18 mm mesh sized fyke-nets between November December 2021. Totally 88 specimens have been Turkish part River, Hatay, Türkiye. Lengths weights ranged 10.2 29.8 cm 19.47 408.59 g, respectively. The b-values calculated as 3...
