Paper Details

The present study was conducted to find out breeding performance of live bearer ornamental fishes such asmolly(P .sphenops),guppy(P .reticulata),platy (X . maculatus)and swordtail(X . helleri) using photoperiod [onemonth(L) and one month(D)]alternately for a period of three months. During this period ,effect of photoperiod observed on brooder,in which one month (L) and one month (D) phases were maintained alternately in four different glassaquaria setups named as SI to SIV , in which molly, guppy, platy and swordtail were kept in ratio of one male and twofemales respectively to observed their breeding performances such as number of youngones, survival rate percent, mortality rate percent and body colour change. Similarly for next three months, same photoperiod phases were maintained infour different glass aquaria setups named as SA to SD to observed effect of photoperiod on growth performance ofyoungones such as average mean length ,average mean weight, specific growth rate percent, percent weight gainpercent and colour change. A proper water quality management were done throughout study period and physiochemicalparameters such as temperature, pH, dissolved oxygen, nitrite, nitrate , ammonium, phosphate and total hardness wereobserved and maintained using standard water analysis kits . Feed management were done twice in a day using driedpelleted and dried live frozen feed. Chemical analysis were done after seven days of partial water change to disinfectbrooder and their youngones using chemicals such as ‘Rid-All-Copper Aid’, ‘Rid-All-General Aid’ and methylene blue.The aim of present study was to found out whether this type of photoperiod phases were playing any role in successfulbreeding or not ,whether helpful in providing healthy crops or not, also whether it going to boost our national incomeand progress or not. From economic point of view , this type of photoperiod phases should not be applied for breeding ofthese fishes as from study it was quiet cleared that their beautiful colour appearance seems to be lost due to change inbody colour ,which in turn not imparting any benefit to entrepreneurs and women self help group, inorder to have asuccessful living condition and hence overall hampering national income and progress.
