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(greenlight,15w for 4hrs)which were maintained for a period of three months in four different glass aquaria setups named asSI to SIV , in which molly, guppy, platy and swordtail were kept in ratio of one male and two females respectively toobserved their breeding performances such as number of youngones, survival rate percent, mortality rate percent andbody colour change. Similarly for next three months, same photoperiod phases were maintained in four different glassaquaria setups named as SA to SD to observed effect of photoperiod on growth performance of youngones such asaverage mean length ,average mean weight, specific growth rate percent, percent weight gain percent and colourchange. A proper water quality management were done throughout study period and physiochemical parameters such astemperature, pH, dissolved oxygen, nitrite, nitrate , ammonium, phosphate and total hardness were observed andmaintained using standard water analysis kits . Feed management were done twice in a day using dried pelleted anddried live frozen feed. Chemical analysis were done after seven days of partial water change to disinfect brooder andtheir youngones using chemicals such as ‘Rid-All-Copper Aid’, ‘Rid-All-General Aid’ and methylene blue. The aim ofpresent study was to found out whether this type of photoperiod phases were playing any role in successful breeding ornot ,whether helpful in providing healthy crops or not, also whether it going to boost our national income and progressor not. From economic point of view , this type of photoperiod phases should be applied for breeding of these fishes asfrom study it was quiet cleared that their beautiful colour appearance remains as such for newly brooders but thosetaken from dark/light phases, on them body colours started to came back progressively throughout study period,it wasunique sign inorder to correct colour disappearance of brooders and youngones those were suffered from colourdisappearance during dark/light phases or kept in dark place for breeding procedures. Also to create generalawareness among research scholars ,entrepreneurs and women self help group ,to used this valuable information duringbreeding of these fishes, inorder to have a successful living condition and hence overall promoting national income andprogress.
