<![CDATA[Copepoda pada dasarnya adalah udang berukuran mikroskopik yang menjadi rantai pakan alami yang penting di perairan bebas. Investigasi jenis-jenis copepod lokal akan membantu menyiapkan informasi untuk pengembangan budidayanya sebagai jasad pakan alami. Penelitian dilakukan dengan mengkoleksi jenis Cyclopoida lokal perairan pantai Gerokgak, Buleleng, Bali, diisolasi dan dikembangbiakkan dengan pakan kombinasi antara alga Nannochloropsis oculatta, tepung terigu, ragi roti, dan hati ayam dalam tangki beton 5 m3. Tiga ratus individu Cyclopoida yang membawa telur ditempatkan pada tiga wadah kultur bervolume satu liter. Pengamatan pada pertumbuhan individu dilakukan dengan sampling setiap hari dan setiap dua hari untuk melihat perkembangan telurnya. Jenis Cyclopoida lokal termasuk famili Cyclopidae dan genus Apocyclops spp. Kecepatan pertumbuhan mencapai 20 µm setiap harinya, dan dari fase copepodit mencapai ukuran dewasa membawa telur dianalisis selama 12 hari, perkembangan telur memerlukan waktu maksimal 10 hari, sehingga estimasi siklus umur minimal adalah 22 hari. Produktivitas rata-rata telur Apocyclops spp. pada penelitian ini diestimasi sebanyak 36 (minimum16-maksimum 65) butir per individu betina. Penelitian kultur lebih lanjut difokuskan pada optimalisasi suhu, salinitas, oksigen terlarut pada media hingga optimalisasi pada jenis pakan.Copepod, a microscopic shrimp, is an important member in natural food chain in waters. Investigating the types of local copepod will provide valuable information for the development of other natural live feed culture. The research was carried out by collecting local Cyclopoida species from Gerokgak coastal waters, Buleleng Regency-Bali, isolated and cultured with combination feed of algae Nannochloropsis oculatta, wheat flour, yeast bread and chicken liver in 5 m3 concrete tank. Three hundred individuals of Cyclopoida carrying eggs were placed in three beaker glasses of one-liter culture volume. An observation on the individual growth was done by daily sampling and every two days to see the development of the eggs. The type of local Cyclopoid was classified as Cyclopidae family in the genus of Apocyclops spp. The growth rate reached 20 ìm per day, and from copepodite to adult carrying eggs took 12 days, the egg development took maximum 10 days, and the estimate of the minimum age cycle was 22 days. The average productivity of egg of Apocyclops spp. in this study was estimated to be 36 (min. 16-max. 65) eggs per female. Further culture studies focusing on the optimization of temperature, salinity, dissolved oxygen in the media and nutritional aspects, need to be further studied.]]>
