We conducted a 84-day nutritional feeding experiment with dried whole cells of DHA-rich marine microalga Schizochytrium sp. (Sc) to determine the optimum level fish-oil substitution (partial or complete) for maximum growth Nile tilapia. When we fully replaced fish oil (Sc100 diet), found significantly higher weight gain and protein efficiency ratio (PER), lower (improved) feed conversion (FCR) intake compared control diet containing (Sc0); no significant change in SGR survival rate among all...

High protein content, excellent amino acid profile, absence of anti-nutritional factors (ANFs), high digestibility and good palatability fishmeal (FM), make it a major source in aquaculture. Now, FM is at risk due to an increase its demand price. So, there greatest need find cheap sources replace FM. Plant are acknowledged best their large availability low cost. However, they have certain ANFs, deficiency some acids, nutrient bioavailability poor presence starch fiber. These contrasting...

Microalgae companies increasingly seek markets for defatted biomass that is left over after extracting omega-3 rich oil human nutraceuticals and crude fuels. Such a protein-rich co-product promising alternative to unsustainably sourced fishmeal in aquaculture diets. We report the first evaluation of marine microalga Nannochloropsis oculata (N. co-product) replacing diets Nile tilapia, globally important species. conducted nutrient digestibility experiment with N. dried whole cells...

We determined apparent digestibility coefficients (ADCs) of macronutrients, amino acids and fatty for freshwater (Spirulina, SPI; Chlorella, CHL) marine (Schizochytrium, SCI) microalgal ingredients in Nile tilapia via four diets: reference (Ref containing fish plant feedstuffs) SPI, CHL SCI (Ref/dried algal cells at 7:3). ADCs crude protein were significantly higher SPI than CHL, comparing well with literature values fishmeal feedstuffs. all essential generally SPI. Very high lysine...

Abstract Aquafeed manufacturers have reduced, but not fully eliminated, fishmeal and fish oil are seeking cost competitive replacements. We combined two commercially available microalgae, to produce a high-performing fish-free feed for Nile tilapia ( Oreochromis niloticus )—the world’s second largest group of farmed fish. substituted protein-rich defatted biomass Nannochloropsis oculata (leftover after extraction nutraceuticals) whole cells docosahexaenoic acid (DHA)-rich Schizochytrium sp....

Abstract Household kitchen waste (HKW) is produced in large quantity and its management difficult due to high moisture content complex organic matter. Aerobic composting of HKW an easy, efficient, cost-effective eco-friendly method. This study designed achieve a zero-waste concept convert HKW. We optimized the type size three different bulking agents speed up process. The tested were fallen leaves, sawdust fly ash. results showed higher longer thermophilic phase (55 o C) for 11 days C2....

Aquaculture feed formulation has recently turned its focus to reduce the reliance on marine-derived resources and utilise alternative feedstuffs, as an approach improve environmental sustainability of aquaculture sector. The fish oil market is highly volatile, availability this commodity continuously decreasing for use in aquaculture. Currently, a growing number commercial efforts producing microalgae are providing omega 3-rich sustainable feed. This study was focused determine nutrient...

Introduction In the current study, Cirrhinus mrigala was used as an animal model to investigate impacts of Moringa oleifera leaf meal (MOLM) on their overall performance reared in six earthen ponds. Methods this fishmeal (FM) substituted with MOLM at various levels diet: 0% (control), 10, 15, 20, 25, and 30%, for a six-month feeding trial. A total 270 fish 15 fingerlings (15.31 ± 0.12 g/fish) stocked each ponds triplicates. Results When compared other experimental control groups, analyses...

The presence of off-flavor compounds in fish represents a significant economic problem encountered aquaculture production. are due to the absorption substances produced by range microorganisms. Currently, number strategies have been used prevent or limit growth these Therefore, it is important evaluate effectiveness via monitoring concentrations recirculating system. In vivo solid-phase microextraction (SPME), rapid and simple sample preparation method, will allow concentration live fish....

Aquaculture, the fastest growing food sector, is expected to expand produce an additional 30 million metric tons of fish by 2030, thus filling gap in supplies seafood for humans. Salmonids aquaculture exploits vast majority fishmeal and oil rendered from ocean-dwelling forage fish. Most diverted these commodities are human-food grade, all primary prey marine predators. Rising costs, price volatility, environmental sustainability concerns using feed driving global search alternatives,...

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

Reliance on fish meal can be reduced by incorporating plant-based ingredients, making aquaculture more economical, sustainable and environmental friendly. In this study, the efficacy of plant protein ingredients (PPI) such as mustard oil cake (MOC), soybean (SBM) rice bran (RB) Partial substitute fishmeal (FM) was investigated for a commercially important fish, Labeo rohita in cages 90 days. Three experimental diets, labeled Diet 1, 2, 3, were formulated to isonitrogenous (with content...

Abstract With the anticipated foliar application of nanoparticles (NPs) as a potential strategy to improve crop production and ameliorate heavy metal toxicity, it is crucial evaluate role NPs in improving nutrient content plants under Lead (Pb) stress for achieving higher agriculture productivity ensure food security. Herein, Brassica napus L. grown Pb contaminated soil (300 mg/kg) was sprayed with different rates (0, 25, 50, 100 mg/L) TiO 2 ZnO-NPs. The were evaluated growth attributes,...

Abstract Cadmium toxicity in the soil is an alarming issue, and among innumerable approaches, microbe-facilitated nanoparticle application for alleviation of Cd stress a well-accepted technique.
