Peningkatan Kinerja Pertumbuhan Benih Ikan Gabus (Channa striata) dengan Probiotik EM4 Increasing Growth Performance of Snakehead Fish Seeds (Channa Striata) With Probiotic EM4

Berkurangnya populasi ikan gabus (Channa striata) di alam perlu dijaga kelestariannya melalui budidaya. Penggunaan probitik dalam budidaya dapat mendukung peningkatan produksi. Tujuan penelitian ini untuk mengetahui pengaruh frekuensi pemberian probiotik terhadap kelangsungan hidup, pertumbuhan, konversi pakan, dan proksimat tubuh pada benih ikan gabus yang dipelihara selama 60 hari. Penelitian dilakukan menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan 3 kali ulangan. Perlakukannya adalah frekuensi pemberian probiotik, meliputi satu kali sehari; dua kali sehari; tiga kali sehari; dan tanpa pemberian probiotik (kontrol). Hasil penelitian menunjukkan frekuensi pemberian probiotik berpengaruh terhadap kelangsungan hidup, pertumbuhan, konversi pakan dan kandungan proksimat tubuh benih ikan gabus. Frekuensi terbaik adalah pemberian probiotik dua kali sehari. Kata kunci: pakan buatan; probiotik; pertumbuhan; proksimat tubuh; ikan gabus. ABSTRACT The decreasing population of snakehead fish (Channa striata) in nature needs to be preserved through cultivation. The use of probiotics in cultivation can support increased production. This study aimed to determine the effect of the frequency of probiotics on survival, growth, feed conversion, and body proximate in snakehead fish fry for 60 days. The study was conducted using an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment is the frequency of giving probiotics, including once a day, twice a day, three times a day, and without probiotics (control). The results showed that the frequency of probiotic administration affected survival, growth, feed conversion, and proximate content of snakehead fish seed bodies. The best frequency is the provision of probiotics twice a day. Keywords: artificial feed; probiotics; growth; body proximate; snakehead fish.
