PENGARUH PENAMBAHAN PROBIOTIK KOMERSIL PADA PAKAN TERHADAP PERTUMBUHAN IKAN KAKAP PUTIH (Lates calcalifer)

Abstract

Penelitian ini bertujuan untuk mengetahui dosis terbaik probiotik EM4 dan pengaruh penambahan probiotik EM4 pada pakan untuk pertumbuhan benih ikan kakap putih. Penelitian ini dilaksanakan pada bulan September 2019 di kantor pengawasan Sumber Daya Kelautan Perikanan Dompak Kepulauan Riau. Metode yang digunakan ialah eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan P0= Tanpa probiotik P1= Penambahan probiotik EM4 3 ml/kg P2= Penambahan probiotik EM4 6 ml/kg P3= Penambahan probiotik EM4 9 ml/kg. Menggunakan analisis data dengan One-Way ANOVA menunjukkan bahwa penambahan probiotik pada pakan memberikan hasil terbaik pada perlakuan C yaitu penambahan probiotik dengan dosis 9 ml/kg, dimana pertumbuhan bobot harian (0,45±0,03 g), pertumbuhan panjang harian (0,06±0.00 cm), pertumbuhan bobot mutlak (20,27±1,54 g), pertumbuhan panjang mutlak (2,91±0,30 cm), efesiensi pakan (39,24±4,79 %), rasio konversi pakan (2,78±0,38 %) dan kelangsungan hidup (100,00,±0,00 %) lebih baik dibandingkan dengan perlakuan lainnya.

THE EFFECT OF ADDING PETROFISH PROBIOTICS TO FEED AT DIFFERENT DOSES ON THE GROWTH AND SURVIVAL OF BARRAMUNDI (Lates calcarifer) JUVENILES

“…According to Arsyad et al 14 , these 12 bacteria can dominate the fish's digestive tract, and the presence of pathogenic bacteria will decrease so that the fish can utilize these good bacteria to grow and be healthy. 15 stated that the proportion of probiotic bacterial colonies in feed causes the activity of probiotic bacteria to work optimally in fish digestion so that the fish's digestive capacity becomes higher in absorbing food essences and producing good growth. In improving feed nutrition, the bacteria contained in probiotics have a mechanism for producing several enzymes for digesting feed, such as amylase, protease, lipase, and cellulose.…”

“…Feeding barramundi juveniles with a mixture of probiotics provides differences for each treatment. The good effects for the host caused by probiotics are adjusting the number of bacteria in the digestive tract and producing lactic acid, which can increase the effectiveness of enzymes and help the digestion of food 15 . The lower the feed conversion value, the less is needed to produce 1 kg of fish meat.…”

“…Feed with the addition of probiotics has better quality compared to feed without probiotics. Giving probiotics can increase the efficiency of feed utilization 15 .…”
