Abstract Improving feed suitability and bolstering the global upsurge in fish production is a strategic challenge for aquaculture. The utilization of plant animal derived ingredients aquafeed achieving sustainable finfish aquaculture affected by various factors, including presence antinutritional lowered nutrient bioavailability, indigestible particles microbial contaminants. Applying fermentation to overcome these problems has received considerable attention recent years as provides...

Four isonitrogenous isocaloric diets used study were a control diet based FM, 30% FM replaced H. (HiP), FO (HiO), both (HiPO). Diets fed twice day satiety triplicated groups barramundi...

Abstract Utilising novel ingredients in aquafeeds is necessary for the continued expansion and intensification of aquaculture production. Microalgae are utilised widely a variety purposes; as live feed fish shellfish larvae juveniles, production algae‐based meals oils to replace marine derived raw materials aquafeeds, astaxanthin, carotenoid that gives salmon flesh its characteristic reddish colour. Notably, long‐chain polyunsaturated fatty acids, amino proteins, fibres, antioxidant...

Seaweed, also known as macroalgae, represents a vast resource that can be categorized into three taxonomic groups: Rhodophyta (red), Chlorophyta (green), and Phaeophyceae (brown). They are good source of essential nutrients such proteins, minerals, vitamins, omega-3 fatty acids. Seaweed contains wide range functional metabolites, including polyphenols, polysaccharides, pigments. This study comprehensively discusses seaweed seaweed-derived metabolites their potential feed ingredient in...

This study investigated the effects of tuna hydrolysate (TH) inclusion in fishmeal (FM) based diets on growth performance, innate immune response, intestinal health and resistance to Streptococcus iniae infection juvenile barramundi, Lates calcarifer. Five isonitrogenous isoenergetic experimental were prepared with TH, replacing FM at levels 0% (control) 5%, 10%, 15% 20%, fed fish apparent satiation three times daily for 8 weeks. The results showed that containing 5% 10% TH had significantly...

This study investigated the effects of replacement fishmeal (FM) with poultry by-product (PBM) protein, supplemented black soldier fly, Hermetia illucens (HI) larvae on growth, histomormhology, immunity and resistance to Vibrio harveyi in juvenile barramundi. Two hundred twenty five barramundi averaging 3.51 ± 0.03 g were randomly allocated into three groups fed isonitrogenous isocalorific diets containing different levels PBM HI as follows: Control (FM based diet), 45PBM + (45% 10% HI),...

The present study investigates if the total replacement of dietary fishmeal (FM) with poultry by-product meal (PBM), supplemented methionine influences muscle fatty acids composition, normal gut morphology, histological traits liver, muscle, and gill, liver enzymes, immune antioxidant response, stress-related gene in juvenile barramundi, Lates calcarifer relation to growth feed utilization. Barramundi (3.58±0.01g) were randomly distributed into six 300 L seawater recirculating tanks (25...

The effects of feeding different levels poultry by-product meal (PBM) replacing fishmeal (FM) protein, supplemented with tuna hydrolysate (TH) and Hermetia illucens (HI) larvae, on the growth, fillet quality, histological traits, immune status, oxidative biomarker gut microbiota juvenile barramundi, Lates calcarifer were investigated for six weeks. Barramundi fed four isonitrogenous isolipidic diets in which a FM based diet was used as Control (Diet1) compared other non-FM containing 80%,...

Despite the enormous anthropogenic and environmental hazards affecting wild fisheries resources, southern coastal waters are still considered one of aquatic biodiversity hotspots in Bangladesh.Therefore, present study was conducted to make a complete account fishes assess their condition conservation status rivers spread across four districts Bangladesh.During period from January December 2014, total 98 species fish were recorded belonging 81 genera, 48 families 13 orders.Perciforms as most...

This study was conducted to characterize the causative agent of streptococcosis in tilapia (Oreochromis niloticus) and control Streptococcus infection by means garlic (Allium sativum) supplementation. The morphological, biochemical polymerase chain reaction amplification confirmed 11 isolates belong iniae from infected fish eyes tissue samples. Random screening 12 well-known medicinal plant parts against S. revealed extract as most effective herbal recovery infection. In vivo challenge test...

Poultry by-product meal (PBM) has been utilised as a substitute of fishmeal (FM) in many aquaculture species. However, little information is known regarding the use bioprocessed PBM (BPBM) production. This study was undertaken to investigate whether replacing FM with BPBM improved growth performance, gut morphology and fatty acid synthesis juvenile barramundi, Lates calcarifer. The by baker yeast, Saccharomyces cerevisae Lactobacillus casei. used replace at 75% 100% (75BPBM 100BPBM)...

Abstract Dietary supplementation is an effective strategy for boosting the innate immune response in fishes. It involves use of functional ingredients that bear potential mitigating deleterious effects chemotherapeutics (bioaccumulation and development drug‐resistant pathogens), as a more ecologically responsible approach to fish farming. With emergence probiotics, prebiotics, synbiotics herbal immunostimulants; dietary has become integral aspect immuno‐nutrition. In this review, we have...

The present study examined the efficacy of dietary selenium-enriched spirulina (SeE-SP) on growth performance, antioxidant response, liver and intestinal health, immunity disease resistance Asian seabass, Lates calcarifer. A total 480 seabass juveniles with an initial weight 9.22 ± 0.09 g/fish were randomly assigned to four groups. fish fed a fishmeal protein replacement diets SeE-SP at 5%, 10%, 20%, namely SeE-SP5, SeE-SP10, SeE-SP20, fishmeal-based diet as control for 8 weeks. results...

The fish fed for 56 days four experimental diets i.e., Control (Formic 0 + Pediococcus acidilactici 0), FA 0.3% Probiotic Pro P. 0.1%), FA+Pro 0.1%)....

The mucosal surfaces of fish, including their intestines, gills, and skin, are constantly exposed to various environmental threats, such as water quality fluctuations, pollutants, pathogens. However, cells microbiota closely associated with these work in tandem create a functional protective barrier against conditions. Recent research has shown that incorporating specific feed ingredients into fish diets can significantly boost general immune response. Among the being investigated, insect...
