Arowana farming in Bukit Merah



One of them is Bukit Merah Aquaculture (M) Bhd. Its managing director, Ahmad Don, says the farm is not only a supplier but also imports and exports Arowana.

There are 141 ponds in the farm, which are divided into three sections. And in each pond, there are between 10 and 50 Arowanas of a single species. The species that are available include the Indonesian super red, high-backed golden, green, one-and-a-half red as well as the silver Arowanas.

One of the workers said the Arowanas were fed with bloodworms, prawns, tiny silver fishes and other protein-based manufactured food.

Each Arowana takes between three and four years to mature, growing up to 45cm and to weighing over a kilogramme.

He said the male fish had a large mouth and deep lower jaw to incubate the larvae.

When a pair of Arowana mates, the female will release a small volume of orangy-red eggs. After fertilisation, the male will absorb the fertilised eggs into its lower jaw for incubation.

“Every two months, the Arowanas in each of the ponds will be scooped out using strong nets.

“If larvae are found in the adult male’s mouth, they are skillfully extracted into plastic bags filled with water. This is done while the fishes are just below water level,” he said.

The larvae, when taken out of a fish’s mouth, will each appear to be carrying a sac of orange yolk under their bellies.

The man in charge of the incubators will then empty each of the plastic bags containing the larvae into a small vessel and place it at the bottom of a glass tank. The larvae are left to incubate in the glass tank for two weeks. At the end of the period, the fry would have grown about three centimetres, but with yolks still hanging from their bellies.

He will then empty the vessel into another bigger glass tank, with a bigger space for the fry to move.

The fry will be kept in the tank for a month before they are transferred into another tank for two months. At this time, the yolks will disappear.

At the end of the two months, he will transfer them into the fourth tank. These vigorous eaters are fed with tiny river prawns. After six months, the Arowanas, which would have grown between six centimetres and eight centimetres, would be sold off.

The company sells each of the super red Arowanas at RM1,500, the high-back golden at RM500, one-and-a-half red at RM180, green at RM100 and silver at RM15.

OKU miliki 17 kolam ikan air tawar

PEKAN 26 Okt. - Di mana ada kemahuan, di situ ada jalan.

Itulah perumpamaan yang sesuai bagi menggambarkan kegigihan seorang kurang upaya yang kini memiliki sebilangan kolam ikan air tawar hasil usahanya dalam bidang akuakultur di Kampung Tanjung Pulai di sini sejak lapan tahun lalu.
Dengan hanya berbekalkan modal permulaan sebanyak RM1,200 dan sebuah kolam ikan air tawar pada tahun 2000, Mohd. Khairi Othman, 31, yang kudung kedua belah tangan dan kaki sejak lahir, kini bergelar usahawan yang mempunyai 17 kolam ikan air tawar.
Lebih mengagumkan, Mohd. Khairi yang berkerusi roda dan terpaksa mengesot memasuki ladang ternakannya, mampu menguruskan kolam tersebut bersendirian dan meraih pendapatan ribuan ringgit sebulan.
''Aspek penjagaan harian seperti memberi makanan dan pemantauan saya lakukan sendiri.
''Bagaimanapun, saya akan mengupah beberapa pekerja untuk mengangkat ikan dari kolam," katanya kepada Utusan Malaysia ketika ditemui di kampung itu, baru-baru ini.
Mohd. Khairi yang masih bujang berkata, dia bertekad memulakan projek ternakan ikan air tawar tersebut apabila menyedari kekurangan yang ada pada dirinya dan berasa perlu melakukan sesuatu demi memperbaiki taraf hidupnya.
''Saya mula menimba pengalaman dengan membantu salah seorang saudara saya menguruskan kolam ikan air tawar miliknya di sebuah kawasan berdekatan kampung ini.
''Sejak itu minat timbul dan dengan bermodalkan RM1,200 serta sebuah kolam ikan yang dipinjamkan oleh saudara saya itu pada tahun 2000, saya memulakan perniagaan sendiri," katanya.
Mohd. Khairi memberitahu, ketika ini kolam ikannya mampu mengeluarkan lebih 600 kilogram ikan talapia dan patin bagi setiap lima bulan.
Menurutnya, pasaran ikan air tawarnya tertumpu di pasar-pasar basah di daerah ini selain orang ramai yang datang terus ke ladang ternakannya itu.
Ditanya mengenai rancangan masa depan, dia bercadang menambah kolam ikan sedia ada, sekali gus meningkatkan hasil pengeluarannya.
Tambahnya, kekurangan pada diri bukan halangan untuk maju dalam bidang yang diceburinya itu sebaliknya menganggapnya sebagai cabaran.
''Saya berpegang kepada prinsip bahawa setiap kekurangan pasti ada kelebihan," tegasnya
