A first insight into genotype x diet interactions in European sea bass (Dicentrarchus labrax L. 1756) in the context of plant-based diet use ArchiMer
Le Boucher, Richard; Vandeputte, Marc; Dupont-nivet, Mathilde; Quillet, Edwige; Mazurais, David; Robin, Jean; Vergnet, Alain; Medale, Francoise; Kaushik, Sadasivam; Chatain, Beatrice.
This preliminary study assessed genotype x diet interaction in late growth of European sea bass (Dicentrarchus labrax) fed with either a fish meal (FM)- or a fish oil (FO)-based diet (M) or an all-plant-based (PB) diet. A total of 550 fish from 224 families were reared together and tagged. DNA was sampled and microsatellites were used to assign parentage. When fish weight was 192 +/- 54 g, two tanks were fed with M (FM: 100%; FO: 100%) and two others with PB (FM: 0% and FO: 0%). Body weight (BW), fork length (FL) and fillet lipid content (CorrFat) were analysed with a linear model and with REML methodology. We observed no significant differences between groups, but a slightly lower (P=0.03) daily growth coefficient in sea bass fed PB than in those fed M....

A shortcut method for sexing juvenile European sea bass, Dicentrarchus labrax L. ArchiMer
Menu, Bruno; Peruzzi, Stefano; Vergnet, Alain; Vidal, Marie-odile; Chatain, Beatrice.
The objective of this study was to develop a rapid and effective method of sexing juvenile sea bass with minimum labour and material. To this end, the gonad squash mount technique was applied along with macroscopic techniques for sexing a large number of experimental fish at the age of 215-275 days post fertilization (p.f.). At this age, 90% of the 3894 fish could be unambiguously sexed by macroscopic examination of their gonads, whereas the remaining proportion was identified using squash mount preparations (10%). The accuracy of the observations was measured up to classical histology procedures. Undifferentiated fish accounted for 0.1% of the total population only. The application of the squash mount technique holds out the prospect of considerable...

Combining Individual Phenotypes of Feed Intake With Genomic Data to Improve Feed Efficiency in Sea Bass ArchiMer
Besson, Mathieu; Allal, Francois; Chatain, Beatrice; Vergnet, Alain; Clota, Frederic; Vandeputte, Marc.
Measuring individual feed intake of fish in farms is complex and precludes selective breeding for feed conversion ratio (FCR). Here, we estimated the individual FCR of 588 sea bass using individual rearing under restricted feeding. These fish were also phenotyped for their weight loss at fasting and muscle fat content that were possibly linked to FCR. The 588 fish were derived from a full factorial mating between parental lines divergently selected for high (F+) or low (F–) weight loss at fasting. The pedigree was known back to the great grand-parents. A subset of 400 offspring and their ancestors were genotyped for 1,110 SNPs which allowed to calculate the genomic heritability of traits. Individual FCR and growth rate in aquarium were both heritable...

Early individual electronic identification of sea bass using RFID microtags: A first example of early phenotyping of sex-related growth ArchiMer
Ferrari, Sebastien; Chatain, Beatrice; Cousin, Xavier; Leguay, Didier; Vergnet, Alain; Vidal, Marie-odile; Vandeputte, Marc; Begout, Marie-laure.
Although individual electronic tagging using PIT (Passive Integrated Transponder) tags is well established, it is mainly used for fish > 60 mm in length. Since electronic tagging is an ideal identification method, we used RFID (Radio Frequency Identification) microtags (6 mm in length, 1 mm in diameter, 10 mg in mass) to characterize individual fish from the early stages of their development and throughout their lifecycles. We used sea bass, Dicentrarchus labrax, (105 day-old fish weighing between 100 and 1100 mg) and studied the effects of intra-coelomic tagging in half the population using different endpoints including survival and tag reading, growth over 6 months and swimming responses. Dead fish were counted daily, biometric data were collected at...

Effect of selection for fasting tolerance on feed intake, growth and feed efficiency in the European sea bass Dicentrarchus labrax ArchiMer
Daule, Sophie; Vandeputte, Marc; Vergnet, Alain; Guinand, Bruno; Grima, Laure; Chatain, Beatrice.
Feed efficiency is a major goal for aquaculture sustainability, and selecting fish to genetically enhance this trait would be highly valuable. However, no selective breeding program specifically targeted to feed efficiency exists for farmed fish, mostly because of the difficulty of measuring individual feed intake. However, a negative phenotypic correlation between feed efficiency and weight loss at fasting has been previously demonstrated in sea bass submitted to feed deprivation (FD). We mated sea bass parents selected for their high (FD+) or low (FD-) weight loss at fasting to produce FD+ and FD- progeny, which were reared in a single tank to avoid common environmental effects. At 8 months of age, 1200 of those fish were submitted to three alternating...

Effects of fasting and re-alimentation on gill and intestinal morphology and indicators of osmoregulatory capacity in genetically selected sea bass (Dicentrarchus labrax) populations with contrasting tolerance to fasting ArchiMer
Alix, Maud; Blondeau-bidet, Eva; Grousset, Evelyse; Shiranghi, Ainaz; Vergnet, Alain; Guinand, Bruno; Chatain, Beatrice; Boulo, Viviane; Lignot, Jehan-herve.
Fasting and refeeding occur naturally in predators but this is largely ignored when dealing with farmed fish. Therefore, the effects of 3-week fasting and re-alimentation (2.5% of the individual body mass) were investigated using two genetically selected populations (F2 generation) of 250 g juvenile sea bass (Dicentrarchus labrax L.). Blood osmolarity, gill and intestinal morphology and expression of the sodium pump (Na+, K+-ATPase, NKA) were studied on two phenotypes showing different degrees of body mass loss during food deprivation: one group losing body mass rapidly during fasting (F +) and the other one limiting body mass loss during the same period (F-). Blood osmotic pressure significantly decreases due to re-alimentation in both groups, but this...

Estimates of genetic variability and inbreeding in experimentally selected populations of European sea bass ArchiMer
Hillen, J. E. J.; Coscia, I.; Vandeputte, Marc; Herten, K.; Hellemans, B.; Maroso, F.; Vergnet, Alain; Allal, Francois; Maes, G. E.; Volckaert, F. A. M..
The aquaculture industry has increasingly aimed at improving economically important traits like growth, feed efficiency and resistance to infections. Artificial selection represents an important window of opportunity to significantly improve production. However, the pitfall is that selection will reduce genetic diversity and increase inbreeding in the farmed stocks. Genetic tools are very useful in this context as they provide accurate measures of genetic diversity together with many additional insights in the stock status and the selection process. In this study we assessed the level of genetic variability and relatedness over several generations of two lines of experimentally selected European sea bass (Dicentrarchus labrax L.). The first line was...

Estimation of genetic parameters of feed conversion ratio based on individual phenotypes and genomic data in sea bass ArchiMer
Besson, Mathieu; Allal, Francois; Chatain, Beatrice; Vergnet, Alain; Clota, Frederic; Ferrari, Sebastien; Vandeputte, Marc.
We estimated genetic parameters of feed conversion ratio (FCR) and daily growth coefficient (DGC) using individual phenotypes measured in aquariums under a restricted feeding regime and genomic information on 2,722 SNP markers. The results showed a moderate heritability of both traits (0.26 for FCR and 0.41 for DGC) as well as close to unity negative genetic correlation between them. Thus, FCR of fish in aquariums could be improved by selecting fish for higher DGC. Nevertheless, these results must be taken with caution until we know whether individual FCR measured in aquariums also reflects the FCR of fish reared in groups.

Evaluation of behavioral changes induced by a first step of domestication or selection for growth in the European sea bass (Dicentrarchus labrax): A self-feeding approach under repeated acute stress ArchiMer
Millot, Sandie; Pean, Samuel; Leguay, Didier; Vergnet, Alain; Chatain, Beatrice; Begout, Marie-laure.
Among other strategies to improve fish welfare in rearing environment, domestication and/or selective breeding was proposed to minimize fish responsiveness to husbandry practices. To verify this hypothesis on a recently domesticated specie, the sea bass, Dicentrarchus labrax, L., an experiment was realized, using four populations differing according to their level of domestication or selection: one population produced from wild parents (Wild), one population produced from parents domesticated for one generation (Domesticated) and two produced from parents selected for growth for one generation (Selected A and Selected B). The experiment was carried out over 91 days with 600 fish (50 fish per tank, 150 fish per population). After a control period, the fish...

Fitness of early life stages in F1 interspecific hybrids between Dicentrarchus labrax and D. punctatus ArchiMer
Ky, Chin-long; Vergnet, Alain; Molinari, Nicolas; Fauvel, Christian; Bonhomme, Francois.
Inter- and intraspecific crossbreeding experiments were conducted to evaluate the aquaculture potential of hybrids in the genus Dicentrarchus, focusing on fertilisation and hatching success. The experimental design consisted of 24 controlled crosses in which individual and pooled fertilisations were made between wild D. labrax individuals (8 dams and 5 sires originating from West Mediterranean and Atlantic populations) and wild D. punctatus (6 sires). Three experiments were successively performed: (1) dams from the Mediterranean population, individually considered to have good egg quality, (2) dams from Mediterranean population, individually considered to have poor egg quality and (3) crossbreeding using pooled eggs from the Atlantic population. In each...

Genetic variation of resistance to Viral Nervous Necrosis and genetic correlations with production traits in wild populations of the European sea bass ( Dicentrarchus labrax ) ArchiMer
Khanh, Doan Quoc; Vandeputte, Marc; Chatain, Beatrice; Haffray, Pierrick; Vergnet, Alain; Breuil, Gilles; Allal, Francois.
Viral Nervous Necrosis (VNN) disease is considered as one of the most serious threats for European sea bass cultured in Mediterranean Sea, with no simple and effective procedures to treat this disease. In this study, 1472 offspring resulting from artificial full factorial mating of western Mediterranean dams with sires from four different wild populations of European sea bass (Northern Atlantic, NAT; Western Mediterranean, WEM; Northern-East Mediterranean, NEM; and Southern-East Mediterranean, SEM) were challenged by experimental infection to W80 betanodavirus strain in order to evaluate genetic variations for VNN resistance among populations and genetic correlations between VNN resistance and production traits. The results showed a large variation of VNN...

Genotype by diet interactions in European sea bass (Dicentrarchus labrax L.): Nutritional challenge with totally plant-based diets ArchiMer
Le Boucher, Richard; Vandeputte, Marc; Dupont-nivet, M.; Quillet, E.; Ruelle, Francois; Vergnet, Alain; Kaushik, Sadasivam; Allamellou, J. M.; Medale, F.; Chatain, Beatrice.
Aquaculture of carnivorous species has strongly relied on fish meal and fish oil for feed formulation; however, greater replacement by terrestrial plant-based products is occurring now. This rapid change in dietary environment has been a major revolution and has to be taken into consideration in breeding programs. The present study analyzes potential consequences of this nutritional tendency for selective breeding by estimating genetic parameters of BW and growth rates estimated by the thermal growth coefficient (TGC) over different periods with extremely different diets. European sea bass (Dicentrarchus labrax L.) from a factorial cross (1,526 fish) between 25 sires and 9 dams were used to estimate heritabilities and genotype by diet interaction. Starting...

Genotype by environment interactions for growth in European seabass (Dicentrarchus labrax) are large when growth rate rather than weight is considered ArchiMer
Dupont-nivet, Mathilde; Karahan-nomm, Bilge; Vergnet, Alain; Merdy, Olivier; Haffray, Pierrick; Chavanne, Herve; Chatain, Beatrice; Vandeputte, Marc.
Two hundred fifty three full-sib families from 33 males and 23 females of European seabass were produced in a partly factorial mating design. All fish were reared in the same tank for 14 months until reaching mean weight of 35 g. then 7000 of them were individually tagged and weighed, and dispatched to four farms in different locations (France, Israel, Italy and Portugal) representing a wide variety of environmental conditions. Around mean weight of 400 g. 1177 to 1667 fish at each site were weighed. Daily growth coefficient (DGC) was calculated. Pedigrees were successfully redrawn for 99.2% of fish using microsatellite markers. Genetic correlations between sites were high for body weight (>0.80 in all cases but one, i.e., five cases over six), but only...
