The use of ambon banana (Musa paradisiaca var. sapientum) stems flour in grouper (Epinephelus lanceolatus ♂× Epinephelus fuscoguttatus ♀) floating net cage nursery

The study aimed to test the effectiveness of ambon banana stems flour through feeding on health status and performance groupers reared in sea floating net cages. (8.27 ± 0.20 cm length 11.69 0.50 g weight) were 1 m × 1.5 cages with a stocking density 112 fish /m3 for 42 days. feed was commercial 46% 48% protein, which added 30 g/kg coating method. This consists three treatments replications, i.e. at beginning 7 days (A), 14 (B), without (control). observed parameters production performance, morphometric, hematological test, water quality. results showed that between not significantly different (P>0.05). Based morphometric total treatment A increased (P <0.05) compared control B. On 14th day it known highest erythrocyte, hemoglobin, hematocrit, leukocyte found B, however, differential did differ addition Ambon first (B) can improve but has been able increase grouper.

 ABSTRAK
 Tujuan penelitian ini adalah menguji efektivitas tepung batang pisang dalam pakan terhadap kesehatan dan kinerja produksi ikan kerapu yang didederkan KJA di laut. Ikan berukuran 8.27 dengan bobot rata-rata dipelihara (kedalaman air 2,5 m) kepadatan ekor/m2 selama hari. Pakan digunakan komersil protein 48%, selanjutnya ditambahkan sebanyak metode coating. Penelitian menggunakan tiga perlakuan ulangan yakni pemberian awal pemeliharaan hari tanpa (kontrol). Parameter diamati produksi, morfometrik, uji hematologi pengukuran kualitas air. Hasil menunjukkan antar tidak berbeda signifikan Berdasarkan pada morfometrik bagian panjang untuk ditemukan peningkatan (P<0.05) dibandingkan kontrol Pada ke-14 diketahui eritrosit, hematokrit leukosit tertinggi terdapat sedangkan nilai diferensial Penambahan pertama dapat meningkatkan kesehatan, namun belum mampu kerapu.
