The present study was conducted to find out growth and maturation of newly born youngones of swordtailusing different photoperiods (13hrs.,16hrs.,19hrs.,22hrs.,24hrs.-Dark ) for a period of 60days, one 15watts , CFL Bulbwere used as source of artificial light in each Setup-I-IV, whereas in Setup-V(24 hrs. dark) were maintained. 20youngones were kept in each Setup-I to V. During study period, the average mean length, the average mean weight,survival rate percent and sex identification were observed. Water quality management were done throughout studyperiod and physico-chemical parameters such as temperature, pH, dissolved oxygen, nitrite, nitrate, ammonia, totalalkalinity and total hardness were measured and maintained using standard water analysis kits. Siphoning done weekly.Feed management were done using dried pelleted feed(Tokyu) and (Optimum)and freeze dried live feed(Blood worm)and (Tubifex) four times in a day with timimgs7 a.m.(Tokyu),11a.m.(Blood worm),3 p.m(Optimum), and 7 p.m.(Tubifex.).During study period growth and maturation were found to be maximum and fast in Setup-IV ( 22 hrs., CFL) andminimum and slow in Setup-III (19hrs.,CFL),while during second months found to be maximum in Set up-IV (22hrs,.CFL) and minimum in Setup-V (24 hrs., Dark).The aim of present study was to find out which photoperiods werebest suited for growth , maturation and survival of youngones, inorder to get healthy crops ,which not only going tomake our country self sufficient in ornamental fish rearing and culture but also help in making a big platform tocompete with world market .It also boost our national income and prestige. In today’s global scenario ornamental fishrearing and culture, act as strong weapon in eradicating unemployment problem. So present study was an attempt to letseveral research scholars, entrepreneurs and women self help groups with basic knowledge in using differentphotoperiods to have a successful and fast growth of swordtails.
