Bung Lin, Saya paling senang baca pengalaman orang. Saya senang baca pengalaman bung Lin. Bagus sekali. Kalau saya pikir-pikir, A Hok itu tidak omong kosong dengan rencananya bantu nelayan pulau Seribu untuk bikin peternakan ikan. Tahun 1986 waktu pertama kali saya dan istri ke Tiongkok, sudah lihat peternakan ikan luar biasa luasnya dengan aerator untuk menaikkan concentrasi 02 dalam air. Setelah ibu saya meninggal, dan ayah merasa berat mengurus perusahaan susu, perusahaan dijual, diteruskan mungkin hanya 2 tahun oleh pemilik baru. Kandang sapinya besar ada untuk 100 sapi. Jadi ada bak makanannya juga 100. Ini disewakan oleh adik saya pada peternak ikan lele. Di Solo itu orang suka makan pecel lele, nasi pecel dengan tambahan lele goreng. Rupanya untungnya bagus dan permintaannya banyak, hingga dia bisa beli tanah luas di desa Mojosongo, pinggir kota. Saya pikir rencana A Hok mau bantu nelayan pulau Seribu bikin peternakan ikan itu dapat dilaksanakan. Di Taiwan saya lihat peternakan ikan berdampingan dengan sawah padi. Yang peternakan ikannya terlihat dari jauh aeratornya. Kalau di New Zealand, kotoran sapi dan kencing itu disemprot jatuh ke bawah, terus ke semacam septic tank, untuk diolah jadi methaan gas. (Sudah baca pengalaman Xi Jinping bikin methaan gas. Dipikir gasnya kok belum keluar, dia buka satu tutup. Tiba-tiba keluar methaan gas dan cairan membasahi bajunya. Tidak diceritakan bagaimana baunya ? ). Overflownya mengandung banyak pupuk nitrogen dalam bentuk nitrat. Bisa dienceri untuk memupuk ladang rumput untuk makanan ternak. Bisa juga untuk peternakan ikan. Ikannya kalau sudah besar, dicacah, untuk makanan babi. Peternakan itu memproduksi susu dan menjual babi. Salam, KH
