salam,
Dalam proses penternakan ikan ketutu pada peringkat asuhan ia itu antara 1-3 inci, benih ikan selalu di serang kulat terutama di bahagian insang. Selalunya ikan akan mati dalam jumlah yang banyak. Salah satu ikhtiar yang bolah di buat ialah dengan mengunakan bahan kimia seperti berikut. Untuk air sepuloh tan, cuba gunakan malichite green sebanyak .02ppm atau .2gm bersama copper sulphate .8ppm atau 8ppm.
Untuk air yang kurang, gunakan teknik membancuh jumlah yang sama untuk 10 tan air dan kemudian mengunakan ubat mengikut bahagian yang di perlukan seperti 10persen atau 30 persen.
Selamat mencuba.

Nursing of 1-2 inches soon hock
Marbled goby in commercial culture have a few distinct culturing stages. These culturing stages are required due to the cannabalistic nature of the fish. Stage 1 involve selection of spawners, providing spawner with the necessary vitamin, spawning, collecting and hatching of eggs, and feeding the larvae for the fish two months. This process will not be discussed here because its a trade secret that involve alot of sleepless night of actually try and error. Stage two involve growing the fish frys from month 3 to month 5 ie from 1-2 inches (4-6cm) to 5 - 6 inches.
1 day eggs
2 days old frys
2 weeks old fry
At this stage the fish is not only canabalistic but are just killers at large. They kill by instinct. They involve in the strategy of less mouth more food. Cannot help it since in nature, food have to be hunted and excess food cannot be kept in ice boxes. This also a stage where we change the diet of the fish from totally natural food to formulated food.
2 months old fish
Firstly, the density of culturing the fish at this stage is about 500-700 pieces in 1 meter cube of water. Water maybe freshwater or slighty brackish up to 5-6ppt. The the water should be about 400-600 cm deep and air lift is used to provide oxygen in the water. Do remember that marbled goby is not an air breeeder and oxygen level of at lest 5 ppm is good for the fish. As for food, the combination of sinking started shrimp pellet with a dose of squid oil and live rice shrimp will be good. 2 days of shrimp pellet and one day of rice shrimp will help the fish to grow to about 4-6 inches in 3 months.
If the nursery is a bit tight interm floor space or the fish is growing too fast, grading should be done every 4 week. However, if the growth is about even, grading should be done at the end of 2 months. The mortality rate during this stage is about 30-40% due to nature and cannabalism.
At the end of this stage, the fish can be grown in grow out tank and feed formulated food totally.

benih ikan ketutu dari Sarawak. ( as posted at kuamm on 28-11-07)
Hari ini saya terima 30kg benih ikanK22 dari Sarawak. Dari pengamatan saya ada hang telah di simpan lebih dari sebulan dan ada yang baru seminggu di simpan. Saiz antara 400gm ke 50gm sekor. Ianya dibungkus dengan ubat anti amonia dan dimasukkan kedalam plastic bag dua lapis yang di ikan bucunya dengan getah. Bucu ini senang koyak. Kemudian di masukkan sedikit pure oxigen dan diikat. Bag plastik ini tidak kembung sepenuhnya sebab nanti dalam kapalterbang ianya boleh meletup. Ikan ini kemudiannya di masukkan kedalam kotak dan di hantar ke klia sebelum di hantar ke kedai kami di Jalan Klang lama.
Inilah ubat anti amonia. 5 ml (satu sudu teh) untuk 10 gelen air laut atau tawar.
Kami telah menyediakan tong tong yang telah di isi sedikit garam. Ikan yang telah di timbang di masuk kan kedalam tong ini dan di biarkan selama setengah jam. Di dapati 2 ekor ikan yang kecil tidak boleh hidup dan di keluarkan. Semua ikan ini bila sampai masih hidup. Selepas setengah jam, kami memasukkan sedikit potassium permaganate dan lampu di bilik itu di tutup. Semua tong mempunyai pump akuarium yang membuat air berpusing.
Dalam masa 24 jam kita akan tenguk ikan yang boleh hidup untuk di bela. kalau mati dalam masa tersebut kami akan dapat rebate dari penjual. hari sabtu ini ikan tersebut akan di hantar ke kolam kami di Sg petani melalui bas. Kita akan tenguk besok berapa banyak ikan yang survive.
