Digestive Enzymes Activity with Gut Morphometric Parameter of Carnivorous Fish Wallago attu (Siluridae, Siluriformes)

Isolation and characterization of polymorphic microsatellite loci in Wallago attu (Teleostei, Siluridae)

Ultrastructural organisation and functional aspects of the olfactory epithelium of Wallago attu (Bleeker).

The topological architecture and functions of different cells of the olfactory epithelium in Wallago attu (Bleeker) have been systematically studied using a scanning electron microscope. The elongated olfactory rosette of the fish consists of 62 to 64 primary lamellae in each left and right rosette. Each lamella is provided with apical sensory epithelium and basal non-sensory epithelium. Topolo...

Siluridae), Distinct Genera of Tropical Asian Catfishes, with Description of †Wallago maemohensis from the Miocene of Thailand

The Southeast Asian silurid catfish genus Wallagonia Myers, 1938, although regarded as a junior synonym of Wallago Bleeker, 1851 by recent authors following Myers (1948), differs fundamentally from it in many external and osteological characters. The genera evidently have been distinct since at least the middle Miocene and apparently are not closely related to each other. Wallagonia seems most ...

Effect of fish oil replacement with dietary soybean lecithin on Growth performance and digestive enzymes activity of juvenile Persian sturgeon (Acipenser persicus)

The purpose of this study was to survey the effect of dietary fish oil replacement with different levels of soybean lecithin on growth performance and digestive enzymes activity of Persian sturgeon. Three hundred and sixty fish with average weight of 85 ± 0.09 g were treated with 6 experimental diets and three replicates, containing 0, 2, 4, 6, 8 and 10 percent soybean lecithin for 10 weeks. Ba...
