“…Astaxanthin accumulation has been shown to correlate with additive genetic effects and is likely heritable, as shown by a single trait mixed model used to estimate heritability of shrimp astaxanthin coloration across a reconstructed pedigree (Nguyen et al, ). Genetic indicator models of sexually selected traits assume that there needs to be sufficient heritability of a trait for it become preferred (Andersson & Iwasa, ).…”

An experimental test of mate choice for red carotenoid coloration in the marine copepod Tigriopus californicus

Colorful ornaments are hypothesized to have evolved in response to sexual selection for honest signals of individual quality that provide information about potential mates. Red carotenoid coloration is common in diverse groups, and in some vertebrate taxa, red coloration is a sexually selected trait whereby mates with the reddest ornaments are preferred. Despite being widespread among invertebrates, whether red carotenoid coloration is assessed during mate choice in these taxa is unclear.The marine copepod Tigriopus californicus displays red coloration from the accumulation of the carotenoid astaxanthin. Previous research on copepods has shown that astaxanthin provides protection from UV radiation and xenobiotic exposure and that carotenoid production is sensitive to external stressors. Because of the condition dependency of the red coloration, we hypothesized that Tigriopus would use it as a criterion during mate choice. To test this hypothesis, we conducted trials in which males chose between females that were wild-type red (carotenoid-rich algae diet) or white (carotenoid-deficient yeast diet). To control for dietary differences and to isolate the effect of carotenoid coloration, we also presented males with restored-red females fed a carotenoid-supplemented yeast diet. We found that wild-type red females were weakly preferred over white females. After controlling for diet, however, we found that restored-red females were avoided. Our observations do not support the hypothesis that male copepods prefer the carotenoid coloration of females during mate choice. We hypothesize that algal-derived compounds other than carotenoids play a role in mate choice. Red coloration in copepods appears to be a condition-dependent trait that is not assessed during mating.

“…In shrimp, poor pigmentation was initially described as a disease status (Howell & Matthews 1991), although this was subsequently ameliorated by dietary carotenoid supplementation (Menasveta et al 1993). Recently, pigmentation in banana shrimp has been shown to be heritable (Nguyen et al 2014), indicating there may be a genetic basis to the retention of carotenoid pigments. Crustacean colour variations have also been observed that are unrelated to dietary carotenoids.…”

Crustaceans are cultured extensively around the world in intensive farming systems. High‐performance formulated feeds have been developed for crustacean aquaculture, which are often supplemented with a number of natural and synthetic carotenoid sources. Studies over a number of years have consistently shown that dietary carotenoid supplementation is beneficial for crustacean aquaculture across a range of commercially relevant parameters. Most obvious is the effect on pigmentation, where carotenoid inclusion levels in feeds and duration of feeding diets with carotenoids have been optimised across many species to improve product colour, and subsequently quality and price. However, beneficial effects of carotenoid inclusion have increasingly been demonstrated on other parameters. This review updates the recent progress in our understanding of dietary carotenoid utilisation and storage, and the combined effects of diet, genetics and environment on crustacean pigmentation. In addition, the range of other physiological benefits this class of molecules brings to these animals is summarised. These include improvements in survival, growth, reproductive capacity, disease resistance and stress resistance.

“…The Pacific whiteleg shrimp (Litopenaeus vannamei) is an important crustacean specie that is widely cultured in many countries, especially in Asia and Latin America, where it accounts for about 70% of total crustacean production. Body colour is a trait of commercial importance in crustacean species [1,2]. Many environmental factors largely influence this trait, including light and water temperature [3]; water quality, e.g., the effect of copper [4]; substrate colour [5]; dietary astaxanthin levels [6]; and, rearing tank colour schemes [7].…”

“…Although many studies have shown abundant evidence that shrimp colour can be improved through the manipulation of environmental factors, quantitative genetic basis of this trait while specifically considering objective measurements of body colour is limited in shrimp species [3]. To date, only two studies reported heritability for body colour of banana shrimp based on visual assessment of dark or light colour [1] and Pacific blue shrimp while using the L*a*b* system [9]. The results from these studies suggested that either dark colour of raw or red colour of cooked shrimp could positively respond to genetic selection.…”

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.
