On the compatibility of fish meal replacements in aquafeeds for rainbow trout. A combined metabolomic, proteomic and histological study.

Project description:The sustainable development of modern aquaculture must rely on a significant reduction of the fish meal (FM) used in aquafeed formulations. However, FM substitution with alternative ingredients in diets for carnivorous fish species often showed reduced nutrient absorption, significantly perturbed metabolisms and histological changes at both hepatic and intestinal level. In the present study, adult rainbow trout (Oncorhynchus mykiss) were fed three different experimental aquafeed formulations. A control diet with higher FM content (27.3%) than two test formulations in which fish meal was substituted with two more sustainable and promising alternatives: insect meal (Hermetia illucens larvae=10.1%, FM=11.6%) and poultry by-products meal (PBM=14.8%; FM=11.7%). Combined metabolomics and proteomics analyses of fish liver, together with histological examination of liver and intestine demonstrated that a well balanced formulation of nutrients in the three diets allowed high metabolic compatibility of either substitutions, paving the way for innovative and sustainable use of novel raw materials for the fish feed industry. Results show that the main metabolic pathways of nutrient absorption and catabolism were essentially unaltered by alternative feed ingredients, and also histological alterations were negligible. It is demonstrated that substitution of fish meal with sustainable alternatives does not impact on fish metabolism, given proper efforts are put in fulfilling nutritional requirements of rainbow trout.

Gene expression profiling of white bass when fed fish meal or fish meal replacement diets

Project description:White bass (Morone chrysops) are a popular sportfish throughout the southern United States, and one parent of the commercially successful hybrid striped bass (M. chrysops x M. saxatilis). Currently, white bass are cultured using diets formulated for other carnivorous fish, such as largemouth bass (Micropterus salmoides) or hybrid striped bass and contain a significant percentage of marine fish meal. Since there are no studies regarding the utilization of alternative proteins in this species, we evaluated global gene expression of white bass fed diets in which fish meal was partially or totally replaced by various combinations of soybean meal, poultry by-product meal, canola meal, soy protein concentrate, wheat gluten, or a commercial protein blend (Pro-Cision). Significant differential expressed genes and gene ontology of pairwise comparisons between control diet and each test diet are presented and discussed.

Label free shotgun proteomics to disclose the impact of methionine-enriched diets in the liver of European seabass

Project description:Plant-based protein sources play an important role in aquaculture by dwindling fish meal to sustainable levels. However, the use of such feedstuffs requires nutrient supplementation to fulfil fish nutritional requirements. This work addressed the response in the liver of farmed fish to dietary methionine (Met), assessing at the same time the growth performance. Fish were fed at suboptimal levels of dietary Met (0.77% w/w; M0.65 diet), within (1% w/w Met; M0.85 diet)and above(1.36 % w/w Met (M1.25 diet); 1.66% w/w Met(M1.5 diet)) the estimated requirement for this species, in a total of four tested conditions. The impact of dietary methionine supplementation in seabass juvenile’s performance was assessed through 85 days of trial, between May and August of 2018. Fish were reared in triplicate tanks and three liver samples/tank (9 per treatment) were collected for liver proteome analysis at the end of the trial i.e., after 85 days of feeding.

Long-term dietary replacement of fish meal and fish oil in diets for rainbow trout: effects on intestinal and hepatic gene expression

Project description:In the context of replacing fish meal and fish oil in feeds for aquaculture, rainbow trout alevins received from first-feeding onwards, one of the three experimental diets: V (100% plant-based), C (mix of FM-FO & plant ingredients) or M (100% FM-FO based). The long term effects of such dietary replacement on the intestinal (mid gut) and hepatic transcriptome were studied in juveniles after a 7-month feeding trial at 7°C.

Effects of the total replacement of fish meal and fish oil with plant protein and oil sources on the hepatic transcriptome of two European sea bass (Dicentrarchus labrax) sub-families exhibiting different growth potentials on an all plant-based diet

Project description:Comparison of the hepatic transcriptomes for two half-sib-families of European sea bass fed on vegetable and fish diet. These two half-sib-families exhibit similar growth on fish diet while significantly different on vegetable diet. The aim of the study is to point out the large panel of metabolic and physiological effects induced by total substitution of both fish meal and fish oil in the diets of European sea bass and to reveal physiological characteristics associated to the two half-sib-families.

Functional genomic analysis of the impact of camelina (Camelina sativa) meal on Atlantic salmon (Salmo salar) distal intestine gene expression and physiology

Project description:Fish were fed a standard fish meal (FM) diet or a diet with partial replacement of FM with solvent extracted camelina meal (CM) (8%, 16% or 24% CM inclusion) during a 16-week feeding trial. A significant decrease in growth performance was seen in fish fed the CM inclusion diets. A 44k oligonucleotide array experiment was used to identify any differentially expressed transcripts in the distal intestine of the fish fed the 24% CM diet compared to the control. The expression level of these genes was validated using quantitative polymerase chain reaction, which was also used to measure transcript expression in the fish fed the 8% CM and 16% CM diets. Histopathological analysis was used to quantify any physical signs in inflammation in the distal intestine of the Atlantic salmon fed the CM-containing diets.

Transcription profiling by array of Danio rerio fast skeletal muscle from fish fed a single satiating meal

Project description:The F5 generation of a wild-caught population of zebrafish (Danio rerio) from Mymensingh, Bangladesh, were used in this study. Replicate experiments were carried out with adult male fish aged 9 months. Each group was maintained in a 50L tank at 27M-11.5M-:C and 12:12h dark:light photoperiod and fed bloodworms (Ocean NutritionM-^Y, Belgium) to satiety for one week. The experimental protocol involved fasting fish for 7 days and subsequent refeeding a single meal of bloodworms delivered over a 3h period, after which any uneaten food was removed from the tank. Seven fish were sampled at -156, -24, 0 (prior to the meal), 0.75, 3, 6, 7.5, 9, 11, 24, 36h and killed humanely by an overdose of ethyl 3-aminobenzoate methanesulfonate salt (MS-222). Six samples from the 0, 3, and 6h time-points were used in the microarray hybridization.
