FISHBOOST results: Perceptions on aquaculture production and selective breeding
In the FISHBOOST project, one work package is dedicated to investigating existing perceptions of aquaculture production. The work consisted of two parts, one part focussed on the perceptions of representative organisations within and surrounding the aquaculture sector, the other part focussed on the perceptions of (individual) aquaculture producers in specific. These perceptions are important to us, they give us an idea of the context in which the FISHBOOST research results will land and of the efforts we will have to make to get these results successfully implemented in the aquaculture sector of today.

FISHBOOST Results: Feed conversion ratio can be improved by selection for controlled lipid deposition
FISHBOOST researchers have shown that prevention of excessive lipid deposition improves feed conversion ratio in rainbow trout. This also increases, yet slowly, the efficiency at which the fish utilizes proteins of feed (protein-retention efficiency), one of the most expensive and limited raw materials of the fish feeds.

FISHBOOST Movie is online!
Aquaculture Breeding and FISHBOOST
FISHBOOST Movie aims to briefly inform the public about the aquaculture production and breeding. The movie explains the principles of selective breeding in farmed fish and the contribution of FISHBOOST project to the European aquaculture breeding with a comprehensible language.

FISHBOOST "Up one level in breeding for six fish species"
European fish breeders can now integrate tools and technologies developed in FISHBOOST into their breeding programmes.
The main goal of the EU supported project FISHBOOST is to advance selective breeding to the next level for the six main finfish species in European aquaculture. These species are Atlantic salmon, rainbow trout, gilthead seabream, European seabass, turbot and common carp.

TEDxTalks "Reducing overfishing by improving the fish itself"
FISHBOOST partner Kasper Janssen (Wageningen UR) was live on TEDxTalks giving his speech responding to the question "How can selective breeding contribute to more sustainble fish production?"
Kasper Jansen participated to the TEDxTalks on November 30, 2016 in Breda, the Netherlands. In his speech Kasper explained the role of aquaculture and selective breeding to the sustainable fish production and on environment. He briefly explained the improvements in genetic of bred fish by giving examples from different fish species and advanced traits. He finalised his talk by expressing his wishes to transform aquaculture into a better alternative to fisheries by making use of the lessons learned in livestock breeding.

FISHBOOST Results: one of the largest co-ordinated genotyping by sequencing efforts
FISHBOOST has successfully performed one of the largest co-ordinated genotyping by sequencing efforts in the world to date.
In work package 1 (WP1) of the project, large-scale disease challenge experiments were performed for several species and diseases (see Table), and samples were collected for sequencing. For each disease challenge experiment, between 800 and 1600 individual fish samples were genotyped using various Restriction-site Associated DNA (RAD) sequencing approaches (RAD-Seq, ddRAD-Seq, 2bRAD-Seq).
The different RAD techniques were chosen according to the skills and experience of the laboratories involved and the characteristics of the experimental design and the genomes of the species.

FISHBOOST Results: New insights into genetic resistance to viral nervous necrosis (VNN) in European sea bass
Improving genetic resistance of farmed fish to infectious disease is one of the major goals of the FISHBOOST project. Viral nervous necrosis (VNN) is a disease that has a large negative impact on aquaculture of sea bass in several European countries.
In a collaborative FISHBOOST experiment, a team comprising The Roslin Institute at the University of Edinburgh, and French partners Ferme Marine Du Douhet, SYSAAF, ANSES, Ifremer and INRA, made a significant breakthrough in the use of genetic markers to understand and improve resistance to VNN in sea bass. A genomic prediction approach was taken to assess the accuracy of prediction breeding values for VNN resistance.This analysis demonstrated that breeding values can be estimated with high accuracy, significantly improving the state-of-the-art method which relies on pedigree information for breeding value prediction.
More results at EAS 2016
Christos Palaiokostas (University of Edinburgh) will present these results at the FISHBOOST session of the European Aquaculture Society meeting in Edinburgh on 23 September 2016.

FISHBOOST Results: Genetic background of winter survival in carp
Common carp is one of the most cultured freshwater fish species worldwide and is one of the targeted fish species in FISHBOOST. Common carp use energetic reserves (fat, glycogen, protein) during winter to maintain their body functions, and thus, these reserves are essential for winter survival. Within FISHBOOST, genetic parameters of body reserves that might affect winter survival in one-year old common carp have beenestimated to assess the potential for using selective breeding to enhance winter survival. Until now, common carp has not been bred using systematic selection programmes and FISHBOOST aims to change this situation.
Presently, first results on estimating these genetic parameters in one-year old common carp before and after wintering are obtained (WP2). Before wintering, low to medium heritabilities (0.13 – 0.35) for the examined traits were observed. In the spring period, the heritabilities for most traits were even higher (0.34 – 0.58). Energetic reserve management seems to have a complicated genetic background, but preliminary results indicate that important traits such as body weight (BW), muscle fat content (MF) and visceral fat (VSI) can be significantly changed in carp by selection.
