The present study was conducted to find out growth and maturation of newly born youngones of guppy using
different photoperiods (6hrs.,12hrs.,18hrs.,24hrs.,24hrs.-Dark and 24hrs.-Sunlight )for a period of 50days.10watts ,two
LED Batten were used as source of artificial light in each setups-A to D ,such that 20watts with 2000lumens,whereas
in setup-E(dark) and in setup-F(Sunlight) were maintained. Each setup with three replicates,20 youngones taken in one,
such that a total 60 youngones were kept in each setup-A to F. During study period ,the average length, the average
weight ,survival rate percent and sex identification were observed. Water quality management were done throughout
study period and physico-chemical parameters such as temperature, pH, dissolved oxygen, nitrite ,nitrate, ammonia,
total alkalinity and total hardness were measured and maintained using standard water analysis kits. Siphoning done
weekly .Feed management were done using live feed(infusoria), freeze dried live feed(tubifex),prepared feed and dried
pelleted feed four times in a day with timing 7a.m., 11a.m.,3p.m. and 7p.m. respectively.During study period,it was
cleared that the growth and maturation were maximum and fast in setup-F( 24 hrs.,Sunlight) and minimum and slow in
setup-A(24hrs.,LED).The aim of present study was to findout which photoperiods were best suited for growth ,
maturation and survival of youngones, inorder to have a healthy crops ,which going to make our country compete with
world market as well boost our national income, prestige and also act as strong weapon in eradicating unemployment
problem. So present study was an attempt to let several research scholars, youth, and women self help groups with basic
knowledge in using different photoperiods to have a successful and fast growth of youngones.
