“…Therefore, the presence of astaxanthin in shrimps was dependent on its availability from the diet, ability to be digested, delivered and deposited in specific location as well as other physical and environmental conditions. The pigmentation of the shrimps is determined by the presence of carotenoid pigments mostly astaxanthin that plays a key role in influencing a consumer s choice to buy shrimps and thus would impact their market value 40 . The results also proved that the TC has a positive correlation with the amounts of astaxanthin complex, free astaxanthin, and other carotenoids present in the extract Table 2 .…”

“…The amount of esterified astaxanthin was determined by the background color of the shrimp during the time of harvesting and the changed chemical form that affected the pigment s location in the chromophores 40 . In addition, the physiological and morphological color changes in crustaceans were related to the rapid and slow transformations resulting from the hormonal and environmental factors 41,42 .…”

“…Carotenoids were triple extracted from freezedried tissue by homogenisation, using an Ultraturrax TP 18-10 (IKA, Staufen, Germany), in equal volumes of iso-amyl alcohol and hexane. Pooled extracts were dried under nitrogen and resuspended in 200l of hexane, before being separated by HPLC using the methods and equipment of Tume et al (Tume et al, 2009). Peaks of free astaxanthin, astaxanthin mono-esters or astaxanthin di-esters were quantified using Empower Pro software (Waters Corporation, Milford, MA, USA) with a peak width of 45s and a threshold of 50-70absorbance units.…”

“…Colouration is dependent upon the presence of astaxanthin within hypodermal tissues (Menasveta et al, 1993;Boonyaratpalin et al, 2001) and must reach a critical level for optimal colouration. However, total hypodermal carotenoid content does not directly correlate with cooked prawn colour and it is the proportions of free and esterified astaxanthin that change in prawns in response to background substrate colour (Tume et al, 2009).…”

SUMMARYExposure of prawns to dark-or light-coloured substrates is known to trigger a strong colour adaptation response through expansion or contraction of the colouration structures in the prawn hypodermis. Despite the difference in colour triggered by this adaptive response, total levels of the predominant carotenoid pigment, astaxanthin, are not modified, suggesting that another mechanism is regulating this phenomenon. Astaxanthin binds to a specific protein called crustacyanin (CRCN), and it is the interaction between the quantities of each of these compounds that produces the diverse range of colours seen in crustacean shells. In this study, we investigated the protein changes and genetic regulatory processes that occur in prawn hypodermal tissues during adaptation to black or white substrates. The amount of free astaxanthin was higher in animals adapted to dark substrate compared with those adapted to light substrate, and this difference was matched by a strong elevation of CRCN protein. However, there was no difference in the expression of CRCN genes either across the moult cycle or in response to background substrate colour. These results indicate that exposure to a dark-coloured substrate causes an accumulation of CRCN protein, bound with free astaxanthin, in the prawn hypodermis without modification of CRCN gene expression. On light-coloured substrates, levels of CRCN protein in the hypodermis are reduced, but the carotenoid is retained, undispersed in the hypodermal tissue, in an esterified form. Therefore, the abundance of CRCN protein affects the distribution of pigment in prawn hypodermal tissues, and is a crucial regulator of the colour adaptation response in prawns.

ABSTRAKPenelitian ini dilakukan untuk menguji pengaruh kondisi lingkungan dengan intensitas cahaya dan warna latar yang berbeda terhadap pertumbuhan dan warna ikan cupang (Betta sp.). Biota uji diberi kombinasi perlakuan perbedaan kondisi cahaya dan warna latar, yaitu: (A-1) 100 lux dan latar putih; (A-2) 100 lux dan latar hitam; (A-3) 100 lux dan latar biru; (B-1) 800 lux dan latar putih; (B-2) 800 lux dan latar hitam; (B-3) 800 lux dan latar biru; (C-1) 1.500 lux dan latar putih; (C-2) 1.500 lux dan latar hitam; dan (C-3) 1.500 Lux dan latar biru. Setiap perlakuan diulang tiga kali. Ikan diberikan pakan berupa larva Chironomus sp. secara ad libitum. Penelitian dilakukan selama 84 hari. Hasil terbaik diperoleh pada perlakuan A-1 (intensitas 100 lux dan latar putih), dengan laju pertumbuhan spesifik panjang dan bobot masing-masing sebesar 0,48 ± 0,06%/hari dan 0,75 ± 0,22%/hari; sintasan sebesar 100%, serta persentase perubahan hue (H), saturation (S), dan brightness (B) berturut-turut adalah 21 ± 18, 6 ± 10, dan 6 ± 18. PENDAHULUANIndonesia merupakan daerah endemik penyebaran ikan cupang alam (wild betta) terbesar di dunia. Ikan cupang alam terbagi menjadi 13 kelompok spesies ditinjau dari karakter morfologinya (Tan, 2011;Goldstein, 2004). Kualitas ikan hias ditinjau dari segi warna dan juga pertumbuhan yang baik. Keragaman dan keunikan warna yang ditampilkan dari suatu produk merupakan karakter komersial penting yang dapat memengaruhi tingkat penerimaan konsumen terhadap suatu produk hewani, sehingga turut menentukan nilai jual produk tersebut di pasar (Colihueque, 2010;Tume et al., 2009). Perubahan warna biasanya terjadi hanya pada kecerahan dan keburamannya saja yang disebabkan adanya perubahan jumlah sel pigmen. Perubahan sel pigmen, terutama melanin, dipengaruhi atau dikontrol oleh hormon pituitari dan adrenalin (yang disekresikan dari otak). Ikan yang dipelihara pada lingkungan yang mendapat cahaya terang akan memberikan reaksi warna yang berbeda dengan ikan yang dipelihara di tempat gelap karena adanya perbedaan reaksi melanosom yang mengandung pigmen melanofor terhadap rangsangan cahaya yang ada (Said et al., 2005). Woods (2000) mengemukakan bahwa pertumbuhan dan sintasan H. abdominalis dipengaruhi oleh warna latar. Warna latar merupakan faktor lingkungan yang paling dominan dalam
