The Effectiveness Of Providing Different Natural Feed Types Of Swordtail (Xiphophorus Helleri) Broodstock On Crude Birth Rate (Cbr)

<p>The most important factor in speeding up fish depends on the food given. The feed given was <br />form of artificial (pellets) because practicality its availability. However, commercially />made course more expensive, and can pollute air compared to natural which />easy be surrounding environment. For this reason, it necessary look for />feed as an effective efficient alternative ripen gonads male female swordtail. />The research used a completely randomized design with 4 treatments 3 repetitions arranged />randomly. Treatment by giving different broodstock swordtail: treatment A />(commercial pellets), B (Daphnia/Moina), C (blood worms) D (mosquito larvae feed).
