Microalgal biomass is a potential feed ingredient that can replace fishmeal and ensure sustainability standards in aquaculture. To understand the efficacy of defatted from marine microalga, Desmodesmus sp. 70-day feeding study was performed with Atlantic salmon (Salmo salar) smolts. Three groups fish (av. wt. 167 g) were offered either control (without microalga) or microalga-containing (10/20%) feeds. At end period, growth indices (condition factor, specific rate) survival microalga-fed not...
Defatted microalgal biomass derived from biorefinery can be potential feed ingredients for carnivorous fish. The present study investigated the growth, intake:gain and health parameters in Atlantic salmon fed 84 days with defatted Nannochloropsis oceania as a fishmeal replacer. Fish feeds containing algal (at 10 20% inclusion, alga groups) were compared groups that consumed alga-devoid (control group). fish received tended to have reduced weight gain specific growth rate. Condition factor,...
Prebiotics are substrates intended to sculpt gut microbial communities as they selectively utilized by the microorganisms exert beneficial health effects on hosts. Macroalga-derived oligosaccharides candidate prebiotics, and herein, we determined of Laminaria sp.-derived alginate oligosaccharide (AlgOS) distal intestinal microbiota Atlantic salmon (Salmo salar). Using a high-throughput 16S rRNA gene amplicon sequencing technique, investigated harbored in content mucus fish offered feeds...
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...
We investigated the ability of lactic acid bacteria, when added individually or in combination feeds, to prevent soybean meal-induced enteritis Atlantic salmon. A control diet, designed induce enteritis, was formulated with marine ingredients and 20% meal. Three more diets were produced by coating diet two either singly (Lactobacillus plantarum; L. fermentum) combination. The fish fed abovementioned for 38 days. performed histological assessments evaluated expression selected mucin...
Probiotics, the live microbial strains incorporated as dietary supplements, are known to provide health benefits host. These microbes manipulate gut community by suppressing growth of certain intestinal while enhancing establishment some others. Lactic acid bacteria (LAB) have been widely studied probiotics; in this study we elucidated effects two fish-derived LAB types (RII and RIII) on distal communities Atlantic salmon (Salmo salar). We employed high-throughput 16S rRNA gene amplicon...
The aim of the study was to investigate apparent digestibility coefficient (ADC) defatted biomass derived from microalgae Nannochloropsis sp. and Desmodesmus when fed Atlantic salmon postsmolts in seawater. Two experiments, one employing cold-pelleted other extruded pellets, were carried out determine ADC dry matter (DM), protein, ash energy. test feeds consisted a fishmeal-based reference feed algal biomass, at ratio 70:30, yttrium oxide as inert marker. DM protein fish...
This study investigated the effects of plant protein concentrates on activity digestive enzymes and microscopic structure intestine juvenile lumpfish. The experiment was carried out using triplicate groups lumpfish 7 g average initial body weight, to 40 final after 54 days. Four experimental diets were used; a fishmeal (FM) based control diet three test with concentrates; soy concentrate (SPC) pea (PPC) (1:1 ratio) replacing FM in proportions 25% (PP25), 50% (PP50) 75% (PP75), respectively....
Cell walls of microalgae differ both in terms chemical composition and architecture. Certain characteristics cell limit the effectiveness extraction valuable constituents nutrient bioavailability bioaccessibility fish. We first investigated potential bead milling to disrupt improve extractability bioactive compounds from Phaeodactylum tricornutum Tetraselmis chui. also evaluated effect mechanical treatment on i) digestibility nutrients two ii) fatty acid pigment content fillet Atlantic...
This experiment investigated the physical qualities (‘Holmen’ durability; ‘tumbling box’ and pellet strength, length diameter) of extruded fishmeal-based feeds produced using different starch sources, screw configurations, with or without steam injected in barrel. The sources tested were native pre-gelatinized potato (PGS), wheat (WS), whole (WW) a combination WS WW. Screw configurations polygon element, followed by two left-pitched segments, Polygon_2L; polygon, one right-pitched...
Rainbow trout with initial body weight 1144 g were fed two diets high (feed A) or low B) water stability for 6 weeks. During the last 2 weeks either stable fluctuating oxygen saturation, salinity and temperature was introduced. High of feed associated harder pellets, less dust formation broken pellets compared to stability. first 4 weeks, intake 23% higher in diet B than those A. Fluctuating environment resulted a severe drop both dietary groups. At termination trial, stomachs contained...
Two experiments were conducted to investigate effects of feed processing conditions and potassium diformate (KDF) supplementation on apparent digestibility nutrients in Atlantic salmon (Salmo salar) physical quality extruded feed. In Exp. 1, diets with raw or expander pretreated full-fat soybean meal (FFSBM) at 100 120 °C 110 °C. Expander pretreatment significantly (P < 0.05) improved the arginine, glutamine tyrosine salmon. The higher FFSBM was confirmed mink (Mustela vison). 2, defatted...
Intestinal inflammation in farmed fish is a non-infectious disease that deserves attention because it major issue linked to carnivorous fishes. The current norm formulate feeds based on plant-derived substances, and the ingredients have antinutritional factors are known cause intestinal fishes such as Atlantic salmon. Hence, we studied inflammatory responses distal intestine of salmon received feed rich soybean derivatives, employing histology, transcriptomic flow cytometry techniques. fed...
