“…Sea urchin gonad colour is associated with the deposition of carotenoid pigment molecules in the tissue (Borisovets, Zadorozhny, Kalinina, Lepskaya & Yakush, 2002;Griffiths & Perrott, 1976;Symonds, Kelly, Caris-Veyrat & Young, 2007;Symonds, Kelly, Suckling & Young, 2009;Tsushima & Matsuno, 1990. Other than a few known exceptions (Moran & Jarvik, 2010;Shukolyukov & Saakov, 2001), animals are unable to synthesize carotenoids de novo.…”

“…Sea urchins are thought to obtain precursor carotenoids from their diet that consists mainly of kelp and seaweeds, which are then modified in the viscera (Symonds et al, 2007;Tsushima & Matsuno, 1990), before being transported to other tissues including the gonad. The major carotenoid present in sea urchin gonads is reported to be 9 0 -cis-echinenone (Symonds et al, 2007(Symonds et al, , 2009Tsushima & Matsuno, 1997).…”

Sea urchins are commercially harvested for their edible gonads, also known as roe or uni. Most species, particularly those from the Northern hemisphere are reported to exhibit limited variation in gonad colour, which is proposed to be due to carotenoid pigments. The commercially harvested species from New Zealand, Evechinus chloroticus, and from Australia, Heliocidaris erythrogramma, however, exhibit considerable gonad colour variation, ranging from a culinary desirable light yellow/orange to an undesirable brown. Gonads from E. chloroticus and H. erythrogramma were characterized spectrophotometrically and the carotenoid content extracted and analysed by reversed-phase high-performance liquid chromatography. The main carotenoid found in the gonads of both species was 9 0 -cis-echinenone, with lower levels of all-trans-echinenone, lutein and isozeaxanthin. Carotenoid composition contributed to the yellow/orange colour components of the gonads, but was not correlated with the darker roe coloration observed in some E. chloroticus individuals. Our results highlight important considerations relating sea urchin gonad coloration to carotenoid content and as such will provide useful information for the future aquaculture and processing of these two species.

“…In the current study, the carotenoids of Sargassum consisted of 92.6% fucoxanthin and 7.4% b-carotene (Table 3). Although Sargassum contained very high amount of fucoxanthin, this carotenoid and its metabolites could be accumulated in urchin gonad (Symonds et al, 2007(Symonds et al, , 2009). The high levels of gonadal echinenone and b-cryptoxanthin detected in the gonads of the three local urchins could be derived from their dietary b-carotene.…”
