“…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. The significant influences of feeding b-carotene on gonad colour have been identified in the cultivation of P. lividus and S. droebachiensis and a positive correlation of dietary b-carotene and the development of gonad colour had been identified (Robinson, Castell, & Kennedy, 2002;Shpigel et al, 2006). b-Carotene, therefore, could be regarded as an important dietary carotenoid that could influence the colour of the urchin gonad, although it is a minor constituent in urchin's natural feed.…”

“…High-quality sea urchin gonads have a uniform yellowish-orange colour that has proven difficult to attain in cultivation trials (Robinson et al 2002). Gonad colour is a function of carotenoid content, and substandard colour is a direct result of carotenoid levels being too high, leading to dark miscolouration, or too low, leading to unattractive paleness.…”

This study documents the effect of sex on gonad carotenoid content during the annual reproductive cycle of Strongylocentrotus droebachiensis from northern Norway. Male and female S. droebachiensis exhibited distinctly different patterns of carotenoid variation, with seasonal carotenoid depletion and replenishment in females and carotenoid retention in males. Females lost approximately 71.1% of their echinenone during spawning, and compensated for the loss by active deposition during gonad regrowth. Female carotenoid levels (100 to 275 µg g -1 dry mass), although lower and less variable than male carotenoid levels, were consistently higher than predicted by estimates based on a constant post-spawning carotenoid content. Males did not lose carotenoids during spawning, and the concentration of carotenoids in male gonads varied from > 600 to < 200 µg g -1 dry mass, apparently as a passive result of increasing gonad size. The results suggest that carotenoid supplements in urchin diets would be largely wasted in gonad enhancement cultivation of male S. droebachiensis, and emphasize the importance of controlling future feeding trials for the confounding effect of sex on carotenoid deposition.

“…Retinol in retinal form was bound with vitelogenin (VTG) then transported to oosit via plasmduring vitelogenesis (Lubzens et al 2003;Sammar et al 2005).. In sea urchin gonad, a big part of carotene are also converted to echinenon through isocriptoxantin (Plank et al 2002;Robinson et al 2002;Shpigel et al 2005).…”

The study aims to determine protein leveland protein energy ratio that producethe best gonad qualityof sea urchin Tripneuestes gratilla. Sea urchin were fed nine test diets with the combination ratio of protein level (%) and protein energy(kcalGE/g) namely; A (22:9), B (22:11), C (22:13), D (27:9), E (27:11), F (27:13), G (32:9), H (32:11), and I (32 : 13). ISSN 2157-6076 2014 www.macrothink.org/jbls 96 Treatment G produced the best gonad quality with gonad weight, gonad protein and gonad colour of 3.49 g, 64.45 % and pale yellow until orange, respectively. Treatmen G also showed carotenoid total ranged from 15 to 18 ppm and β-carotene ranged from 5 to 6 ppm. Moreover, this treatment exhibited gonad weight and gonad protein resulting in significantly difference(P<0.05) protein level ,protein energy ratio and its interaction. However, carotenoid total and β-carotenedid not exhibit any diffrence (p>0.05). Journal of Biology and Life Science
