Epigenetic horizons in aquaculture: unlocking sustainable fish production.

Epigenetics has a profound impact on fish nutrition and aquaculture by regulating gene expression, physiological traits, and growth without altering the underlying DNA sequence. The changes, particularly DNA methylation, can be passed down through generations, enhancing productivity and disease resistance. External factors like temperature, stress, nutrition and illness exposure can also influence epigenetic changes, affecting protein, omega-3 fatty acids, and probiotics.

Processed fish products: a protein source for humans and the challenges faced in processing.

Fish is widely used as a food source and provides an exceptional supply of protein, vitamins, fatty acids, and minerals. The geometric increase in the human population has increased the demand for sufficient food. While fresh fish meat is widely consumed, there is also a growing demand for various processed fish products.

Polymerase Chain Reaction: A Toolbox for Molecular Discovery.

Polymerase chain reaction (PCR), a revolutionary molecular tool, has transformed genetic studies by facilitating rapid DNA amplification. The PCR process relies on several key components: a DNA template or cDNA, two primers, Taq polymerase, nucleotides, and a buffer. These elements collectively facilitate the amplification process, which comprises three stages: denaturation, annealing, and extension.

Fish waste biorefinery: A novel approach to promote industrial sustainability.

In pursuit of sustainability and resource efficiency, concept of the circular economy has emerged as a promising framework for industries worldwide. The global fish processing industry generates a significant amount of waste, posing environmental challenges and economic inefficiencies. The substantial volume of fish waste generated globally along with its environmental impact highlights the urgent need to adopt sustainable practices.

Impacts of microplastic accumulation in aquatic environment: Physiological, eco-toxicological, immunological, and neurotoxic effects.

The presence of microplastics (MPs) in aquatic ecosystem has become a pressing global concern. MPs pose a significant threat to aquatic ecosystems, with devastating consequences for both aquatic life and human health. Notably, freshwater ecosystems are particularly vulnerable to MPs pollution.

Dietary supplementation of black cumin () meal in the formulation of protein-enriched cookies, further in vivo evaluation of protein quality with physicochemical and organoleptic characterization.

has solid historical importance as a medicinal herb and is widely used in the bakery industry. The study revealed that the defatted black cumin meal (DBCM) possesses a high nutritious composition and amino acid profile, such as Leu, Lys, Arg, Phe, and Glu. The supplementation effect of wheat flour with defatted black cumin meal (DBCM) at levels of 5%-25% was explored on the cookies' nutritional, functional, and organoleptic attributes.

Toxicological assessment of dietary exposure of polyethylene microplastics on growth, nutrient digestibility, carcass and gut histology of Nile Tilapia (Oreochromis niloticus) fingerlings.

This study was conducted to ascertain the negative effects of dietary low-density polyethylene microplastics (LDPE-MPs) exposure on growth, nutrient digestibility, body composition and gut histology of Nile tilapia (Oreochromis niloticus). Six sunflower meal-based diets (protein 30.95%; fat 8.

Impact of feeding biochar sources in rohu (Labeo rohita): Evaluating the growth, nutrient absorption, carcass composition, haematology and mineral status.

Biochar, an organic carbonaceous matter, is a unique feed additive that is now being used in aquaculture industry to formulate a cost-effective and eco-friendly diet. This experiment (in door) was conducted over course of 90 days to determine the most effective form of biochar, produced from various sources, for supplementation in Moringa oleifera seed meal-based diet. These sources were: farmyard manure biochar, parthenium biochar (PB), vegetable waste biochar, poultry waste biochar (PWB) and corncob waste biochar, added at 2 g/kg concentration to determine the effect of supplementation on the growth indices, nutrient absorption, carcass composition, haematology and mineral status of Labeo rohita (rohu) fingerlings.

Substitution of fishmeal: Highlights of potential plant protein sources for aquaculture sustainability.

High protein content, excellent amino acid profile, absence of anti-nutritional factors (ANFs), high digestibility and good palatability of fishmeal (FM), make it a major source of protein in aquaculture. Naturally derived FM is at risk due to an increase in its demand, unsustainable practices, and price. Thus, there is an urgent need to find affordable and suitable protein sources to replace FM.

Evaluation of growth, nutrient absorption, body composition and blood indices under dietary exposure of iron oxide nanoparticles in Common carp (Cyprinus carpio).

The bioavailability, small size and direct absorption in the blood, make nanoparticles (NPs) a remarkable feed additive in the aquaculture industry. Therefore, dietary iron oxide nanoparticles (Fe O -NPs) were used to examine their effects on growth, nutrient absorption, body composition and blood indices in Cyprinus carpio (Common carp) fingerlings. Healthy C.

Mango Seed Kernel Fat as a Cocoa Butter Substitute Suitable for the Tropics.

Cocoa butter is a key ingredient in many chocolate products but its partial substitution with mango (Mangifera indica L.) seed kernel fat (MSKF) has the potential to reduce chocolate production costs and improve shelf-life. Here, MSKF was extracted from three cultivars of mango grown in Pakistan: Lal Badshah, Anwar Retual, and Chaunsa.
