Utilization of cinnamon Cinnamomum burmannii leaves and shrimp head in the feed on growth performance of catfish Pangasianodon hypopthalmus

Abstract
Catfish farming has confronted with the problem of slow growth to reach the fillet size and less tender of fish fillets. This study aimed to investigate the effect of cinnamon leaf flour and shrimp head flour in formulated diets on growth of catfish Pangasianodon hypopthalamus. Catfish with an initial weight of 207.04 ± 2.70 g/fish reared in 12 cages with a dimension of 2×1×1.5 m3 (L×W×H) and its fish density was 15 fishes for 60 days. Fish were fed with following experimental diets: (1) Control; (2) cinnamon leaf (1%) (CL); (3) 45% of protein source from shrimp head (SH); (4) CL+SH mix. The fishes fed twice a day with feeding rate 3.5% of fish biomass. The study found that the use of cinnamon leaf and shrimp head increased the specific growth rate 1.67-1.70%, the feed efficiency 57.55-57.67%, and protein retention 55.61% compared to its control (P0.05), respectively. HSI value ranged between 0.3-1.9% compared to its control (P0,05). Nilai HSI ikan patin berkisar antara 0,3-1,9% dibanding kontrol (P<0,05).Kata kunci: Cinnamomum burmannii, kepala udang, pakan, Pangasianodon hypopthalmus, pertumbuhan.
