This study, it was aimed to be enabling to use of fish scale as a bio-indicator for heavy metal pollution that is gradually increase in natural waters. For this purpose scaled carps, Cyprinus carpio (Linnaeus, 1758) were exposed to 7.5, 15, 30 and 60 μg L concentrations of trivalent chromium for 21 day and deformities appearing on the scales were examined under electron microscopy. It was found...

Recently, commercial nanometer sized silver is extensively used for its antibacterial effect; however, nanoparticles may also have ecotoxicological effects after being discharged into aquatic ecosystems. Nanometer sized silver can flow into water ecosystems, where it can exert a variety of physiologically effects in aquatic animals, including fish. The current research aimed to examine the effe...

4 1 Understanding the genomic signatures of population differentiation is fundamental to obtain a 4 2 comprehensive view of the evolutionary process of organisms. Grass carp is one of the most 4 3 important fish species in the world due to its significant value in aquaculture and worldwide 4 4 vegetation biocontrol. However, little is known about the contemporary population structure 4 5 and al...

Macrobrachium rosenbergii popularly known as 'scampi' has been expanding in India recent years. Scampi farming gained momentum after the set-back in shrimp farming due to disease outbreaks and other factors. The infrastructure available to produce shrimp seed and process the shrimp was helpful in providing support to scampi farming. The existing culture system includes both monoculture and poly...

The present study was conducted to reveal a histological analysis on the gills of Labeo rohita and Hypophthalmichthys molitrix specimens were observed to reveal the histo-pathological characteristics of the gills of these freshwater carps. The histological examination of the gills of Labeo rohita revealed the proliferation of bronchial tips, shortening and fusion of secondary gill lamellae, des...

Fish a protein, vitamin rich and fat deficient diet is considered as a vital brain food. Aquaculture has emerged to provide nutritional and food security to people. The three Indian major carps, namely, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala) are the major contributor of Indian aquaculture production. The use of probiotics in aquaculture is becoming increasingly ...
