Restoration Of Pigmentation In Trichogaster Fasciata
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 2
Abstract
Fishes reared in aquarium or in other containers show gradual loss of pigmentation. This is due to the lack of specific pigments molecules. T.fasciata loss their pigmements from 7 days onwards and become dull after 3rd weeks.Synthetic carotenoids such as beta-carotene and lutein has been added along with fish feed, fish meal (30): rice bran (35): mustard oil cake (35) . The carotenoids added feeds are administered and the fish regain colouration from 2nd week.As the use of synthetic carotenoids are very costly for entrepreneurs and farmers, hence use of natural products / materials of both plant and animal origin such as marigold flower petals ( Tagetes minuta ), gulmohor (Delonix regia) and algal powder collected from algal blooms. The pigments are isolated from the dried samples and added along with the feed and fed to the fish. The fish starts the regeneration of pigment from 2nd weeks. However the efficiency of gulmohar and deep coloured marigold petals are more effective.The feed additives prepared from animal matters such as dried cruastaceans carapace, exoskeleton of freshwater prawns, and live chironomids larvae showed most effective restoration of pigments.
