Studies on dietary supplementation of spirulina on Chosen physiological and reproductive parameters in red swordtail xiphophorus helleri

Abstract

To attain the maximum growth coloration and reproductive performance in newlineornamental fish the effects of Spirulina on growth coloration and reproduction were studied newlinein an ovo viviparous ornamental fish Xiphophorus helleri as a function of time The growth newlinecoloration digestive enzymes activities and reproductive performances were increased with newlineincrease in Spirulina levels upto 15 and thereafter declined Duncan multiple range test newlinerevealed that higher levels of Spirulina 15 20 did not differ significantly P gt 0 05 on newlinethe above parameters however they differed significantly P lt 0 05 with lower levels of newlineSpirulina 0 10 Female X helleri fed with 15 Spirulina diet bred three times and newlinereleased more number of fry 386 and it was five times higher than those fed with Spirulina newlinefree diet Based on the present study it is observed that 15 Spirulina diet is better feed newlineadditive to achieve the maximum growth and reproductive performances in X helleri newline newline
