Nutrient availability influences growth, productivity, and community structure of primary producers. Nutrient limitation, however, results from a deficiency mainly in nitrogen (N) or phosphorus (P) levels relative to ...

Quantitative and qualitative analyses of bacterial flora associated with pond water, gills, and intestine of polycultured healthy common carp (Cyprinus carpio) and African catfish (Clarias gariepinus) ...

Melanosis is a major problem associated with the quality loss of Pacific white shrimp. This is mediated by polyphenoloxidase (PPO), in which biochemical and molecular properties can be varied with species, molting period, ...

This study was conducted to explore the effect of kerosene, gasoline, or diesel, on the health status of Nile tilapia, Oreochromis niloticus (L.). Healthy fish (49.5 ± 1.3 g) were exposed to 0.01% (v/v) ...

Enterococci are widely distributed in the environment ranging from foods to humans and are gaining industrial importance due to their technological traits. In the present study, enterococci (Enterococcus faecium NCIM5363 ...

Brazil is becoming one of the main global producers of the shrimp Litopenaeus vannamei. Worldwide outbreaks of viral disease place this aquaculture industry at risk, causing episodic economical loss. The primary ...

International Aquatic Research (IAR) launched in 2009 is a peer-reviewed international journal covering all aspects of aquatic science. The journal attracts articles that can improve the scientific knowledge in ...

Application of high pressure, a minimal processing, has gained interest particularly in extending the shelf-life or modifying the texture of seafood, especially in shrimp. However, pressurization may render the products ...

Fish protein hydrolysates (FPH) have gained increasing attention as nutritious fish products. Lipid oxidation associated with fishy odor in FPH limits its utility. Thus, an appropriate pretreatment of fish mince prior to ...

This study was based on a 3 × 2 factorial design with three levels of dietary protein (25%, 35%, or 45%) and two rearing densities (D 1 = 150 and D 2 = 300 fish/m3). In this study, Nile tilapia, Oreochromis ...

River Gomti, a tributary of river Ganga in northern India, is being polluted due to indiscriminate disposal of domestic sewage and industrial wastes that contain genotoxic chemicals. The study was conducted to evaluate the ...

In many marine fish species, the spermatozoa are immotile in the testis and seminal plasma, and motility is induced when they are released in the aqueous environment. It is well known that the extracellular factors ...

The optimum UV irradiation duration for the complete inactivation of Heteropneustes fossilis egg's nucleus was developed. The unfertilized eggs were suspended in Hanks' balanced salt solution and were irradiated ...

Trypsin was purified from the digestive system of carp Catla catla (Hamilton) by ammonium sulfate fractionation, diethylaminoethyl-cellulose column chromatography, and Benzamidine Sepharose 4 fast flow column ...

We studied the microdistribution of the artificial radionuclide 241Am in the components of Elodea canadensis - a submerged macrophyte of the Yenisei River. The alpha-track analysis showed that the microdistribution ...
