Abstract EN
This study investigated the growth rate, proximate composition, and fatty acid profile in juvenile of kutum Rutile's freesia kutum in different dark-light cycles.
Fish were stocked randomly in eighteen 2000-L fiberglass tanks and received six photoperiod regimes : natural photoperiod, 24L (light) : 0D (day), 16L : 8D, 12L : 12D, 8L : 16D and 0L : 24D.
Application of continuous dark (0L : 24D) and an intermediate photoperiod (12L : 12D) resulted in the highest specific growth rate (SGR) as well as lowest feed conversion ratio (FCR) (P < 0.05) in kutum.
The quantity of crude protein and ash of kutum subjected in continuous dark (0L : 24D), exhibited higher rate than other photoperiod regimes.
The proportion of DHA (docosahexaenoic acid) + EPA (eicosapentaenoic acid) content ranged from 3.20 % in natural photoperiod to 3.52 % in continuous dark, n-3 / n-6 and PUFA / SFA fatty acids ratio slightly ranged from 0.15-0.18, and 0.99-1.08 in all photoperiod regimes, respectively.
