Abstract

Nous avons étudié la dispersion (vitesse, durée, distance) d'alevins de saumon atlantique à l'émergence dans un ruisseau expérimental.Le rythme journalier de dévalaison suit étroitement le rythme d'émergence des alevins, ce qui montre une bonne corrélation entre les deux activités, tout au moins en début de période. Les histogrammes de capture des alevins échantillonnés tous les 10 m présentent des caractéristiques de forme similaires (durée, asymétrie et aplatissement). Jusqu'au pic des captures, près de 50 % des alevins dévalent en 5 jours. Ils se dispersent à partir de la frayère sur 50 m en 3 ou 4 nuits et forment une cohorte homogène d'après leur rythme de dévalaison et leur taille. Après le mode, les captures sont plus étalées dans le temps (environ 10 jours) et montrent plus de variabilité en fonction de la distance. Les alevins résidents ne sont pas distribués uniformément dans les cinq biefs : les densités, de même que les poids moyens, tendent à augmenter vers l'aval. Plus de 50 % de la population d'alevins survivants s'est établi dans les 50 m en aval de la frayère. Les résultats révèlent deux vagues de dévalants. La première vague de dispersion, aussitôt après l'émergence, est rapide et importante. Elle ne dépendrait pas directement de la compétition territoriale et de la densité, mais permettrait d'éviter des densités localement trop élevées et d'utiliser plus efficacement les zones productives situées en aval de la frayère. La deuxième vague d'alevins dévalants correspondrait aux émergents tardifs et aux poissons soumis aux effets de la compétition territoriale., We have analysed the dispersal patterns (rate, duration, extent) of Atlantic salmon fry at emergence. The rate and duration of movement, and the distance travelled were measured in an experimental stream, located near S-Pée-sur-Nivelle, in SW France. A batch of 8 850 eyed eggs, from the grilse wild stock of the Nivelle River, was buried in the gravel substrate at the upstream end of a series of 5 sections, each 10 m long by 3 m wide. Shortly before emergence, drift nets equipped with fry traps were installed at the downstream end of each section. The nets sampled about 1/10 of the flow, except for those nets at the downstream end of the last section which collected all downstream moving fry. The traps were visited every morning and the fry enumerated. At the time of peak movements, samples were collected for length-weight measurements. At the end of the dispersal period, fry which had settled in the different sections (residents) were captured with electro-fishing gear and measured.The pattern of downstream movement of fry in a set of drift nets was closely related to the pattern of emergence from an artificial redd upstream of the nets. Hence, emergence and downstream dispersion were well synchronized, at least during the first part of the dispersal from the redd. The time-frequency histograms of fry sampled every 10 m showed the same pattern and general shape (duration, skewness and kurtosis). Until the peak of captures, nearly 50 % of all downstream moving fry were caught within 5 days in each section. Dispersion from the redd over 50 m occurred within 3-4 nights. During this first period, the fry exhibited similar characteristics with respect to activity patterns and sizes. After the modal day of capture, catches were more evenly spread over time (about 10 days) and showed greater variability in relation to the distance travelled from the redd.Resident fry were not uniformly distributed in the 5 sections : densities, as well as average weights, increased from upstream to downstream. Over 50 % of the surviving fry (75.3 % of planted eggs) settled within 50 m downstream from the redd.Our results showed two waves of downstream dispersion. The first dispersal wave, occurring soon after emergence, was swift and implied large numbers of fry. It was not the result of territorial competition or density, since it occurred before the onset of aggressive behaviour. Rather, this first wave appeared as process to avoid the formation of clumps and allow for a more efficient use of the more productive zones, generally located downstream from the redd. The second wave of downstream moving fry corresponded to late emerging fry and to those fry which, 10-12 days after emergence, were displaced by territorial competition.

Abstract

Through electrophoretic analysis of 14 enzymatic systems corresponding to 31 loci, we studied the change over six generations in the intra- and inter-population variability of salmonid populations from the same initial genetic pool. Four collections of brook trout (Salvelinus fontinalis) and five of brown trout (Salmo trutta) from recently acclimatized stocks in the Kerguelen Islands were examined. The heterozygosity level of these populations remained high and corresponded to the levels of variability observed in other polymorphism studies of the same species. In each species, there was a consistent pattern of genetic differentiation with the "hydrographic proximity" of the populations and with the genetic origin. Within one and the same initial genetic pool, the dendrograms grouped primarily the different ecotypes collected in the same hydrographic system. Thus, these ecotypes seem to result from a behavioral variability within a panmictic population. Finally, establishment of time–genetic distance relationships on the sole basis of electrophoretic data appears unwarranted.

Abstract

Nine induced tetraploid females were artificially inseminated by UV-irradiated sperm collected from diploid males, in order to induce the gynogenetic development of their ova. Most of the resulting embryos were diploid (or minor aneuploids). Several gynogenetic tetraploids, likely to issue from unreduced ova, were also detected in these progenies. The same females fertilized by normal sperm of diploid males gave a majority of triploids and several pentaploids, while the fertilization by normal sperm of tetraploid males gave rise to a majority of tetraploids and one hexaploid. The same crosses, after the eggs had been heat-shocked to double the maternal genetic contribution, yielded about three-quarters pentaploids and one quarter haploids (normal sperm of diploids), or three-quarters hexaploids and one quarter diploids (normal sperm of tetraploids). These haploids and diploids are likely to result from androgenesis.

Abstract

International audience; Genetic experiments were conducted using either random independent full-sib families (9 and 11 respectively) or sire-half-sib families (18) of rainbow trout who were fed an experimental diet supplemented with canthaxanthin. The resulting orange-red colour of the flesh from each fish was analyzed through spectrophotometry and expressed in standard terms of luminosity (Y), dominant wavelength (λd) and excitation purity (Pe). The following results were obtained : - There is a substantial genetic variability among families in each colorimetric parameter. Estimated values of heritability from full-sib and from half-sib families do not differ significantly. - Positive correlation between λd . and Pe, and negative correlations between Y and λd and between Y and Pe, are consistent with the pattern of canthaxanthin deposition in the flesh. Genetic correlations do not differ significantly from phenotypic ones. - Pigmentation intensity is correlated to fish weight. This relationship, however, accounts for but a minor part of colour variation among market-size fishes.; Des expériences génétiques ont été réalisées chez la Truite arc-en-ciel sur des familles aléatoires et indépendantes de pleins-frères (au nombre de 9 et 11) ou demi-frères de pères (18), alimentées par un régime expérimental supplémenté en canthaxanthine. La couleur de chair orange-rouge obtenue chez chaque poisson a été analysée par spectrophotométrie et exprimée en termes standards de luminosité (Y), longueur d’onde dominante (λd) et pureté d’excitation (Pe). Les résultats obtenus sont les suivants : - Il y a une variabilité génétique notable entre familles pour chaque paramètre colorimétrique. Les valeurs d’héritabilité estimées à partir des familles de plein-frères et de demi-frères ne diffèrent pas significativement. - Les corrélations, positives entre λd et Pe et négatives entre Y et λd et entre Y et Pe, sont conformes au mode d’action de la canthaxanthine se déposant dans la chair. Les corrélations génétiques ne diffèrent pas significativement de leurs homologues phénotypiques. - L’intensité de la pigmentation est corrélée avec le poids des poissons. Cette relation toutefois n’explique qu’une part minime de la variation de couleur chez des animaux de taille marchande.

Abstract

The correlated responses in feed intake and G:F ratio with selection for increased growth rate were evaluated by comparing selected (S) and control (C) brown trout (Salmo trutta) reared under conditions known to affect feed efficiency: feed restriction and periods of compensatory growth. Nitrogen and energy requirements for maintenance and growth were also measured. Trout were allotted at comparable BW (3.7+/-0.06 and 3.8+/-0.04 g, for C and S respectively) to triplicate groups per treatment. The experiment lasted a total of 198 d, during which animals were successively submitted to a 116-d feeding phase and fed 10, 30, 50, 70, 100, and 140% of their usual daily ration (UDR), a 35-d phase of food deprivation, and a 47-d refeeding phase. The G:F of C and S were comparable in all experimental conditions tested. During the feeding phase, S grew better than C only when fed 100 and 140% UDR (P0.001). This was explained by a higher feed intake capacity. The requirements for growth and maintenance were similar among the lines, which is in agreement with their comparable loss of weight (mean energy loss of -53 and -55 kJ/(kg x d) for C and S, respectively; P0.38) observed during the feed deprivation phase and the lack of differences in carcass composition (fat, P0.35; protein, P0.54). During the refeeding phase, growth performance and G:F were high in all groups. The daily growth coefficient was higher in S than in C (P0.001) because of a higher feed intake (P0.001). An increase in absolute individual variability in final BW and length was associated with the level of food restriction in both lines; however, it always remained lower in S than in C. In conclusion, fish selected for growth under ad libitum conditions will only exhibit growth superiority when fed diets close to ad libitum, and there was no evidence that selection was associated with an improvement in efficiency of maintenance nor in retention of body tissues.

Abstract

International audience; Many populations of vertebrates display alternative reproductive strategies involving delays in maturation processes and migrations to more productive habitats. Notably for females, migratory patterns and diet could influence reproductive traits such as ova size and number. To test this hypothesis, we targeted anadromous and freshwaterresident female brown trout of various sizes during their return to spawn in tributaries, and carried out stable isotope analyses (d15N and d13C) on ova to identify their feeding areas and diet. The study was performed in the Oir River (France), a small coastal system where trout migrations to sea and within the river basin have been monitored for the last 20 years. General trends were observed in reproductive traits, such as the positive correlation between female fork length, fecundity and ova size. Fecundity was sizedependent whatever the migratory origin of females, but major divergences were seen for ova size and isotopic ratios. Freshwater residents displayed a constant increase in ova size and a 15N-enrichment in ova, suggesting an investment in larger ova and a shift to piscivory as the fish become larger and older. Conversely, anadromous females had smaller ova compared with freshwater-resident females of similar body size and achieved higher fecundity as they grew bigger. Our results suggest the existence of a continuum of reproductive traits for freshwater-resident females whereas anadromous females clearly show a break with this continuum. This major dissimilarity could be explained by the difference in growing environments in terms of food availability and quality.
