Budidaya Fitoplankton, Untuk Apa ?

Budidaya Fitoplankton, Untuk Apa ?

Oleh : Hadi Winarto

Salah satu jasad renik biota air adalah Fitoplankton.

Ciri-cirinya :

  • Memiliki zat klorofil hingga dpt melakukan proses fotosintesa
  • Hidup berkoloni
  • Gerakan lemah
  • Gerakannya mengikuti arah arus air

Fitoplankton sebagian besar terdiri dari ganggang bersel tunggal dan berukuran renik. Biota ini memiliki kemampuan mengolah bahan sintetis (anorganik) yang ada di lingkungannya jadi bahan organik melalui proses fotosintesa. Berbiak sangat cepat melalui pembelahan sel hingga pertumbuhannya dapat didorong dengan memperkaya kandungan bahan anorganik melalui pemupukan. Baik pupuk organik maupun an-organik.

Sumber utama dari anorganik dominan dari unsur :

  • Nitrogen                       = Urea, Za
  • Fosfat                            = TSP
  • Kalium                          = KC1
  • Dan pupuk majemuk = NPK

Pupuk anorganik lebih banyak digunakan karena lebih cepat bereaksi dibandingkan pupuk organik. Fitoplankton tumbuh ideal dikolam dikedalaman air sekitar 80-100 cm, kadar garam maks 25 ppt.

Ini dia pemacu tumbuhnya :

  • Feses unggas             = 1-1,2 ton/ha
  • Dedak                            = 0,25 ton/ha
  • Urea                               = 0,03-0,04 ton/ha
  • TSP                                = 0,04 ton/ha

Agar tumbuh berkala semasa pemeliharaan ikan, secara periodik 7 hari 1x kolam fitoplankton perlu dipupuk ulang. Dalam pemupukan lanjutan ini, diberikan :

  • Feses unggas             = 0,3 ton/ha
  • Pupuk urea                   = 0,02 ton/ha
  • TSP                                = 0,01 ton/ha

Fitoplankton kaya dengan leusin, sangat bagus untuk pakan larva. Bandeng dan bawal suka sekali dengan fitoplankton ini, fitoplankton kaya akan kandungan leusin. Pemberian enzim dan kandungan leusin pada fitoplankton inilah yang memicu pertumbuhan ikan bawal dan bandeng bisa tumbuh hingga 150-150% dibandingkan dengan yang tidak diberi enzim dan fitoplankton.

Jenis jenis fitoplankton yang tumbuh dikolam.

anggota dari ganggang hijau adalah

  • Chlorella,
  • Selanastrum,
  • Dan Scenedesmun.

Fitoplankton dari kelas Flagellata adalah

  • Chlamydomonas,
  • Tetaselmis,
  • Danaliella,
  • Dan isochrysis.

Anggota Diatomeae adalah

  • Cyclotella,
  • Synedra,
  • Navicula,
  • Nitzschia,
  • Chaetoceros,
  • Dan Skeletonema.

Fitoplankton dapat dibudidayakan secara massal adalah :

  • Skeletonema,
  • Chaetoceros,
  • Tetraselmis,
  • Dunaliella,
  • Isochrysis,
  • Chlorella,
  • Nannochloropis
  • Dan Spirulina

Pertanyaannya : Bisakah profit dengan berbudidaya fitoplankton ini ??? Ya bisa
