“…These studies exclusively focused on body and carcass traits that were recorded in selective breeding programs for various aquaculture species, including L. vannamei [17][18][19]; Penaeus monodon [20]; Red Tilapia Oreochromis spp. [21]; Atlantic salmon (Salmo salar) [22]; or, yellowtail kingfish [23]. However, published information regarding genetic correlations for body colour in diverse-cultured environments is not available in any penaeid shrimp species.…”

Body colour, together with growth and survival, are traits of commercial importance in Pacific whiteleg shrimp (Litopenaeus vannamei). However, heritability estimates for objective measurements of body colour are not available in Whiteleg shrimp species, including L. vannamei. Further, the effect of genotype by environment interactions (G × E) on this trait (i.e., the objective measures of body colour) and its genetic associations with growth are not known in this species. The present study presented the first attempt at understanding the genetic architecture of this complex character (body colour) that is of economic significance to the shrimp aquaculture sector world-wide. Specifically, we investigated the quantitative genetic basis of shrimp colour, while using the measurement tool (colorimeter) for a Whiteleg shrimp population reared in two contrasting environments. A total of 5464 shrimp had the objective measurements of body colour (lightness, yellowness, and redness) and growth trait records (weight, length and width). They were the offspring of 204 dams and 197 sires. The restricted maximum likelihood mixed model analysis showed that there were heritable additive genetic components for all of the measurements of shrimp colour, with the heritability (h2) ranging from 0.11–0.55. The h2 estimates for redness and yellowness traits differed between the two environments (h2 = 0.66–0.82 in Khanhhoa vs. 0.00–0.03 in Haiphong). However, the heritability for colour traits was moderate (0.11–0.55) when the two environments were combined. There is existence of (co)-genetic variances between the studied traits. The genetic correlations of body traits with redness or yellowness colour of the shrimp were moderate and positive (a*: 0.13–0.32 for redness and b*: 0.19–0.40 for yellowness). The effect of G × E interactions on shrimp colours could be important, as the genetic correlations for these traits between the two environments were low (−0.41 to 0.16). Our results showed that the genetic improvement for body colour can be achieved through direct selection and the increased redness colour is also expected to have favorable impacts on growth traits. Breeding programs to improve shrimp colour should account for the effects of environmental factors.

“…Yellowtail kingfish (YTK) Seriola lalandi has emerged as an important marine finfish for aquaculture, not only in Australia but also in many other parts of the world including Japan, Latin America (Chile, Mexico), the United States and New Zealand [ 1 ]. In Australia, the hatchery and production technologies have been well established for this species, and a genetic improvement program has started since 2010, using the founder stocks collected from the wild in South Australia [ 2 ]. To date, the selection program for YTK has been practised solely for growth rate.…”

“…Body condition of the fish was also assessed when selection decision was made because there is a demand for well conformed fish from overseas markets [ 3 ]. Genetic evaluation of the first two generations of family selection showed that there was a significant improvement in fry performance by approximately 8% per generation [ 2 ]. Performance testing of growers produced in the second generation (G2) in sea cages however showed lower magnitude of selection response when the selected fish were compared with wild stocks or with offspring of the G1 parents (Premachandra et al, submitted).…”

BackgroundGenomic prediction using Diversity Arrays Technology (DArT) genotype by sequencing platform has not been reported in yellowtail kingfish (Seriola lalandi). The principal aim of this study was to address this knowledge gap and to assess predictive ability of genomic Best Linear Unbiased Prediction (gBLUP) for traits of commercial importance in a yellowtail kingfish population comprising 752 individuals that had DNA sequence and phenotypic records for growth traits (body weight, fork length and condition index). The gBLUP method was used due to its computational efficiency and it showed similar predictive performance to other approaches, especially for traits whose variation is of polygenic nature, such as body traits analysed in this study. The accuracy or predictive ability of the gBLUP model was estimated for three growth traits: body weight, folk length and condition index.ResultsThe prediction accuracy was moderate to high (0.44 to 0.69) for growth-related traits. The predictive ability for body weight increased by 17.0% (from 0.69 to 0.83) when missing genotype was imputed. Within population prediction using five-fold across validation approach showed that the gBLUP model performed well for growth traits (weight, length and condition factor), with the coefficient of determination (R2) from linear regression analysis ranging from 0.49 to 0.71.ConclusionsCollectively our results demonstrated, for the first time in yellowtail kingfish, the potential application of genomic selection for growth-related traits in the future breeding program for this species, S. lalandi.Electronic supplementary materialThe online version of this article (10.1186/s12864-018-4493-4) contains supplementary material, which is available to authorized users.

“…Genetic evaluation of these selective breeding programs in fish showed that selection for high growth did not have significant effects on survival during grow-out, such as in tilapia [3] or common carp [4]. In some studies, improving growth performance was found to be associated with inadvertent increase in survival rate, an example can be found here in yellowtail kingfish [5]. To the best of our knowledge, there is no formal publication on correlated genetic changes in survival to selection for high growth in any shrimp species.…”

BackgroundCorrelated genetic response in survival to selection for high growth has not been reported in giant freshwater prawn (GFP) (Macrobrachium rosenbergii). The main aim of this study was to measure genetic changes and estimate heritability for this character (survival rate) and its genetic associations with body traits in a GFP population selected over eight generations from 2008 to 2015. Statistical analyses were conducted on 106,696 data records, using threshold logistic mixed model.ResultsThe estimated heritability for survival was 0.14 ± 0.04 and significant. Genetic associations of survival with body traits (weight, length and width) were weak, with the estimates of genetic correlations between the traits close to zero. Realised genetic changes in survival, calculated as the difference in estimated breeding values between the selection line and control group within the same generation, was in positive direction but the estimates were not significantly different from zero regardless of the expression unit used either in actual unit of measurement or genetic standard deviation unit. On the other hand, communal testing of stocks in the latest generation, namely G7 (2015), showed that the selection line had 18% higher survival rate than progeny of the wild prawns originated from Mekong river. This result suggests that inadvertent changes in survival occurred during domestication-selection.ConclusionsIt is concluded that selection for high growth had no significant effect on survival in the present population of M. rosenbergii.
