Salinity-induced variations in growth performance, stress biomarkers and biochemical profiles of striped catfish (Pangasianodon hypophthalmus, Sauvage, 1878).

Environmental salinity affects the growth, survival rate and physiological functions of fish. In this study, the effects of salinity stress on Pangasianodon hypophthalmus (Sauvage, 1878) fingerlings were examined over a 90-day period. After acclimatization, a total of 300 P.

Protein sparing by dietary lipids in the diets of Pangasianodon hypophthalmus: an appraisal of growth, body composition, digestive enzymes, and metabolic responses.

Lipid-induced protein sparing conserves protein for growth, reducing feed costs and nitrogenous waste in the environment. In a 90-day experiment, the protein-sparing effects of lipids on the growth, nutrient content, amino acid profile, hematobiochemical parameters, digestive enzymes, and antioxidant status of Pangasianodon hypophthalmus were evaluated. Four isoenergetic diets (3223.

Restoration of skin mucosal immune responses, cyto-genotoxicity and histological alterations in arsenic exposed Labeo rohita by Moringa oleifera supplementation.

Arsenic (As) residue is present predominantly in aquatic ecosystem and fishery products globally, which is critically hazardous to both fish and consumer health beyond its permissible limit. Therefore, finding effective ways to mitigate As toxicity has become a priority. Hence, Moringa oleifera (M.

The measurement of microplastics in surface water and their impact on histopathological structures in wading birds of district Lahore.

Plastics are globally considered a significant threat, particularly to metropolitan areas, due to the extensive use of plastic products. This research is the first of its kind to document microplastics contamination and its effects on Red wettled lapwing (Vanellus indicus). The concentration of microplastics (MPs) was measured from surface water at different locations including canals and drains, which are the primary sources of MPs pollution in the metropolitan city Lahore, Pakistan.

Acute arsenic exposure induces cyto-genotoxicity and histological alterations in Labeo rohita.

Background: Arsenic emerges as most potent hazardous element ranked as number one in ATSDR (Agency for Toxic Substances and Disease Registry) list, can easily accumulate in fish, transported to humans via consumption and affect humans and aquatic organisms. Considering above, current experiment designed to evaluate cyto-genotoxicity and histological alterations induced by arsenic in Labeo rohita used as an animal model.

Methods: By applying complete randomized design sampling acclimatized individuals of Labeo rohita (10 batches of 10 each with triplicates) were exposed to nine definitive doses (12, 14, 16, 18, 20, 22, 24, 26 and 28 mgL) of arsenic in glass aquaria to determine 96-h lethal concentration (LC) of arsenic.

Ameliorative effects of Moringa oleifera leaf extract against arsenic induced histo-biochemical alterations in Labeo rohita.

The current study evaluated the efficacy of Moringa oleifera leaf extract in mitigating the histo-biochemical alterations in Labeo rohita caused by arsenic. A medical plant (Moringa oleifera) known for its numerous pharmacological qualities, was added to three different diets at 0, 2, and 4 % level, prepared by mixing M. oleifera leaf extract with the basal diet.

Administration of vitamin E and C enhances immunological and biochemical responses against toxicity of silver nanoparticles in grass carp (Ctenopharyngodon idella).

The aim of the current study was to evaluate the toxic effect of silver nanoparticles (Ag-NPs) on biochemical biomarkers, immune responses, and the curative potential effects of vitamin C and E on grass carp. Fish (n = 420) with an average initial body weight of 8.045 ± 0.

The influence of dietary protein concentration on digestive enzyme activities, growth, and body composition in juvenile bullseye snakehead (Channa marulius).

The bullseye snakehead (Channa marulius) is considered as an affordable and robust freshwater fish for farming in Asia. However, there is limited knowledge on the species' full nutritional requirements to date with extensive gaps in our knowledge and particularly in precision aspects of protein requirements. Therefore, a three-month feeding trial was conducted under semi-intensive farming conditions to determine the protein requirement of bullseye snakehead using test diets containing 40 (P40), 45 (P45), 50 (P50), and 55% (P55) crude protein levels.

Microplastics abundance in abiotic and biotic components along aquatic food chain in two freshwater ecosystems of Pakistan.

Contaminants of global concern, microplastics (MPs) have been lately reported to be found almost everywhere. Yet there is limited evidence to suggest if these tiny particles can bioaccumulate and biomagnify along the food chain. The current study was conducted to quantify MPs load in two fresh water bodies i.

Evaluation of Fish Health Status and Histopathology in Gills and Liver Due to Metal Contaminated Sediments Exposure.

Health status of freshwater fish, Cirrhina mrigala was studied by qualitative and quantitative histopathological analysis, alterations in frequency/prevalence percentages (%) and histological alteration indices (HAI) in response to metal contaminated sediments of the River Ravi aquatic ecosystem. Histo-structures of gill and liver samples of fish were analyzed and comparison between the degree of damage of the alterations in fish organs was performed after exposure to metal contaminated sediments for 7, 14 and 28 days under semi-static water renewal bioassays. Histopathological studies revealed marked histological alterations in the gills and liver of exposed fish as compared to normal tissue structure observed in control fish.
