      Abstract
      Pemenuhan target produksi ikan lele sangkuriang Clarias gariepinus dilakukan dengan upaya menghasilkan pertumbuhan dan sintasan tinggi serta kemampuan bertahan pada kontrol kualitas dan kuantitas pakan yang baik. Penelitian bertujuan untuk mengevaluasi pengaruh tepung Ulva lactuca pada pakan terhadap kinerja pertumbuhan dan hematologi ikan lele sangkuriang. Penelitian ini terdiri dari perlakuan pakan kontrol (PU0), pakan + tepung Ulva lactuca 40 g kg-1 (PU40), pakan + tepung Ulva lactuca 120 g kg-1 (PU120), dan pakan + tepung Ulva lactuca 200 g kg-1 (PU200) dengan masing-masing tiga ulangan. Pemeliharaan dilakukan di hapa berukuran 1 m × 1 m × 1 m dengan ukuran benih awal 8,64±0,47 cm. PU120 menghasilkan pertumbuhan panjang mutlak tiga kali lipat dari PU0, pertumbuhan bobot mutlak dua kali lipat dari PU0, laju pertumbuhan spesifik 1,5 kali lipat dari PU0, rasio konversi pakan 1,03±0,018, efisiensi pakan 97,18±1,67 %, retensi protein 61,79±0,74 %, retensi lemak 54,50±0,41 %, sintasan 87,14±1,43 %, dan kondisi ikan yang sehat dibuktikan oleh hematologi dengan kadar seimbang. Tepung Ulva lactuca dosis 120 g kg-1 pakan cenderung memberikan kinerja pertumbuhan dan hematologi yang lebih baik.
       
      Achieving production targets in Sangkuriang catfish Clarias gariepinus culture depends on maximizing growth performance, survival rate, and feed utilization efficiency. This research aimed to evaluate the effects of dietary Ulva lactuca meal on the growth performance and hematological responses of Sangkuriang catfish. Four dietary treatments were tested a control diet without Ulva lactuca meal (PU0), and diets supplemented with Ulva lactuca meal at 40 g kg-1 (PU40), 120 g kg-1 (PU120), and 200 g kg-1 (PU200), each with three replicates. Fish with an initial length of 8,64±0,47 cm were reared in hapas 1 m × 1 m × 1 m. The results showed that fish fed the PU120 diet exhibited absolute length growth approximately three times higher than that of the control, absolute weight gain twice than that of the control, specific growth rate 1,5 times higher than that of the control, feed conversion ratio 1,03±0,02, feed efficiency 97,18±1,67 %, protein retention 61,79±0,74 %, fat retention 54,50±0,41 %, survival rate 87,14±1,43 %, and hematological also indicated a better physiological condition. These findings that dietary with Ulva lactuca meal at 120 g kg-1 fed is the optimal inclusion level for improving growth performance and hematological status in Sangkuriang catfish.
