| Summary: | ABSTRACT
Feed is an element which requires largest cost in fish culture. Inefficient in feeding can reduce profit. In additon, intensive fish culture system requires efficiently the use of area. Generally, not all space in fish cage filled by fish, because of the nature of fish that lives in some particular space on water such as the surface, middle space or bottom. Cyprinus carpio andMacrones sp. was reared with gillnet inside gillnet (cage-cum-cage) and fed commercial diet in dose of 3%, 6%, 9% and 12%. Result show that feeding dose of 6% was an efficien mean by relative growth rate. Growth rate of Cyprinus carpio was about 150.47% and Macrones was 208.87%. Feed efficiency was about 81.89%. Survival rate of Cyprinus carpio was about 91.67% and Macrones was 86.67%. Thus, feeding dose of 6% is recommended for Cyprinus carpio andMacrones in cage-cum-cage culture system.

ABSTRAK
Pakan merupakan komponen yang membutuhkan biaya terbesar dalam usaha budidaya. Penggunaan pakan yang tidak efisiensi dapat mengurangi keuntungan usaha. Selain itu budidaya yang intensif juga menuntut penggunaan ruang gerak ikan yang efisien. Umumnya tidak semua kolom air dalam karamba terisi dengan ikan yang dibudidayakan, karena sifat ikan mendiami bagian tertentu dalam air seperti di permukaan, di pertengahan atau di dasar perairan. Ikan mas dan ikan baung dipelihara dengan jaring di dalam jaring (cage-cum-cage) dan diberi pakan dengan dosis 3%; 6%; 9% dan 12%. Hasil menunjukan bahwa dosis pakan 6% merupakan dosis yang efisien dalam penggunaan pakan dengan laju pertumbuhan relatif ikan mas 150,47 % dan ikan baung 208,87%, efisiensi pakan 81,89% dan kelangsungan hidup ikan mas 91,67% dan ikan baung 86,67%. Dosis pakan 6% direkomendasikan sebagai dosis yang sesuai untuk ikan mas dan ikan baung pada sistem cage-cum-cage.
