BENIH KAKAP PUTIH (Lates calcarifer Bloch 1790)
Ikan kakap putih merupakan salah satu komoditas ikan air laut yang memiliki
nilai ekonomis yang tinggi. Namun produksi kakap putih belum mencapai target
produksinya. Salah satu kendala budidaya kakap putih yaitu keterbatasan benih
kakap putih. Benih kakap putih berukuran 3-7 cm mudah mengalami stres dan
memiliki pertahanan tubuh yang rentan terhadap serangan penyakit. Oleh karena
itu perlu dilakukan upaya untuk meningkatkan produksi kakap putih tersebut.
Salah satu upaya yang dapat digunakan untuk meningkatkan laju pertumbuhan
kakap putih yaitu dengan pemberian aplikasi sinbiotik ke dalam pakan. Penelitian
ini bertujuan untuk mengetahui efektivitas sinbiotik terhadap performa
pertumbuhan benih ikan kakap putih. Komposis dosis yang digunakan adalah A (
Kontrol) B (Prebiotik 4ml/100g pakan Probiotik 4ml/100g pakan) C (Prebiotik
4ml/100g pakan Probiotik 6ml/100g pakan) D (Prebiotik 4ml/100g pakan
Probiotik 8ml/100g pakan) E (Prebiotik 6ml/100g pakan Probiotik 4ml/100g
pakan) F (Prebiotik 6ml/100g pakan Probiotik 6ml/100g pakan) G (Prebiotik
6ml/100g pakan Probiotik 8ml/100g pakan). Perlakuan prebiotik maupun
probiotik berpengaruh nyata terhadap pertumbuhan berat mutlak, laju
pertumbuhan harian, rasio konversi pakan serta retensi protein. Perlakuan
sinbiotik hanya berpengaruh nyata terhadap retensi protein. Dosis prebiotik 4
ml/100 g pakan dan probiotik 4 ml/100 g pakan meruapakan dosis terbaik.

Barramundi is one of the seawater fish commodities which has high economic
value. But the production of barramundi has not reached it’s target. One obstacle
to barramundi cultivation is the limitation of barramundi larvae. Barramundi
larvae in the size range 3-7 cm are prone to be stress and have a body's defenses
that are vulnerable to disease. Therefore it is necessary to make efforts to increase
the production of the barramundi. One effort that can be used to increase the
growth rate of barramundi is by giving synbiotic application into the feed. This
study aims to determine the effectiveness of synbiotics on the growth performance
of barramundi larvae. The dosage composition used is, 1 (Prebiotic 4ml/100g
Feed, Probiotic 4ml/100g Feed), 2 (Prebiotic 4ml / 100g Feed, Probiotic6ml /
100g Feed), 3 (Prebiotic 4ml/100g Feed, Probiotic8ml/100g Feed), 4 (Prebiotic
6ml /100g Feed, Probiotic 4ml/100g Feed), 5 (Prebiotic 6ml/100g Feed, Probiotic
6ml/100g Feed), 6(Prebiotic 6ml/100g Feed, Probiotic 8ml/100g Feed). Prebiotic
and probiotic treatments significantly affect the growth of absolute weight, daily
growth rate, feed conversion ratio and protein retention. Synbiotic treatment only
has a significant effect on protein retention. Prebiotic doses of 4 ml/100 g of feed
and probiotics of 4 ml/100 g of feed are the best doses.
