Abstract

This research was carried out at spp (Sekolah Pertanian Pembangunan) Manado Kalasey. The fishwere reared in karamba (9 units) each units contained 50 fish, 14-16 weight. The experiment will be tested using completely random design using 3 deffierent treatment. One treatment is using comercial pellet and two treatmens all using pellets added with and swampcabbage stalk flour 20% and 30 %, each treatment hare 3 replicateries. Feeding frecuenci was 3 times a day and feeding rate was 5 % of their body weight the growth was observed every two weeks. The result analysis from 3 treatment show that the relative growth of treatment A was (312.67%) B was (282.79%), and C (262.41%). The was effisincy feeding foor treatment A was hare (49.43%), B was 48.78% and C was 47.26  5% Where as nutient conversion rate A was are (0%), B was 3.47% and C was (3.82%).Keywords: Swamp cabbage stalk flow (Ipomea aquatica) Nila gif, karamba

Abstract

The research of on the growth of red nila fish measuring 10-12 cm in length and 27-32 g in weight feed with pellet containy different compocition of eceng gondok leaf powder has been carried out in Tondano lake, Eris village, Eris district, Minahasa Agency. The arm of this rescearch is to find out with compotition (10%, 20%, 30%) of pellet from eceng gondok lef that have different composition (10%, 20%, 30%) in pellet give the best relative growth, effisiency value and nutrient convertion value in comparison with commercial pellets. The result showed that pellet contaning 10% eceng gondok powder hed the nigest relative growth (195.4%, efficiency value (61.65) and nutrient convertion value (1.6).  Commercial pellet used as control hower is still relatively better compare with all experimental pellets containing defferent competition of eceng gondok in terms of relative growth, effisiency value and nutrient convertion value. Keywords: Red nila (Oreochormis sp), Eceng gondok pellets (Echhornia crassipes), Set net (jaring tancap)
