breeding arowana in indonesia

Two years ago 4 pool size 4 m x 8 m belongs to PT Arwana Indonesia (PTAI) in Cimanggis, Depok, West Java, it must be drained every week. ' Ponds overgrown by moss, ' said Suwandi, operational manager of PTAI. Moss causes Arowana dissolved oxygen deficiency so must be cast off by draining the pond.

According to Two years ago 4 pool size 4 m x 8 m belongs to PT Arwana Indonesia (PTAI) in Cimanggis, Depok, West Java, it must be drained every week. ' Ponds overgrown by moss, ' said Suwandi, operational manager of PTAI. Moss causes Arowana dissolved oxygen deficiency so must be cast off by draining the pond.

According to , MT, from the Faculty of Civil and Environmental Institute of Technology Bandung (ITB), direct sunlight spur the growth of moss. Its presence in the pond is detrimental if too much. ' Moss needs oxygen to grow so that it and the fish will compete to gain oxygen, ' he added.

Indeed, Arowana does not need to have a lot of dissolved oxygen. Siluk classified as fish that live on the surface of the water so that it can take oxygen directly from the free air. However, there remains a minimum amount of dissolved oxygen levels for the maintenance of arowana to get optimal results, especially for saplings. ' Arowana requires at least 5 ppm of dissolved oxygen to grow optimally, ' said Suwandi. In the low pond dissolved oxygen levels, arowana often look megap-megap.


Shade trees


Suwandi immediately twisted the brain. In its natural habitat, the Arwana live in the river which is overgrown with large trees. ' Meaning artificial shade, net shading is suitable for use, especially in areas with high sunlight intensity such as in Kalimantan and Jakarta, ' said Suwandi. With a net shade the air temperature at the water surface is at a range of 28 – 30 °c as desired arowana. According to Ir Yos Sutiyoso, alumnus of Bogor Agricultural University, reduced intensity of sunlight entering it is able to lower the air temperature.

Suwandi then spread a layer of shade nets with a density of 65% in the middle of the pond. With a density of 65% means that the light that enters the pond is only 35%.

Similarly, the shade nets were also used in the pond spawning of Edo Kristanto in Pontianak, West Kalimantan. However, there the average net covering 10% of the pond area. According to Edo there are 12 spawning ponds with a total area of 12 m x 38 m with a net shading width of 2 m at one of the edges. The shade nets have been used since 2003.

Understandably, around the site there are no large trees that act as a shade when the sun shines. According to Heriyanto, domestic sales manager PT Inti Kapuas International in Jakarta, the shades also makes the pool temperature stable so that the sudden temperature changes can be avoided. ' Air temperature in Kalimantan averages 33 – 34 °c. Without the shade of arowana can be stressful, ' said Heriyanto. The temperature increases it causes dissolved oxygen in water to decline due to evaporation. Consequently arowana lack oxygen.


Mesh distance


Edo attaching the shading net is 3 m from the water surface. The trick is to use a 2 m tall iron pole to support the shade. ' With the sunlight coming in less, but workers can still freely care for arowana, ' said the man who opened showroom Arwana in Meruya, West Jakarta, that.

While PTAI installed the net shading right parallel to the pool height or at least 1.2 m from the water surface. ' So that arowana can not jump to the net that can cause injury, ' said Suwandi. The shade nets are placed in the center of the pond in the direction of the set, while the edges of the pond in the east and west are open. ' The morning and afternoon sun is not usually a day in the daytime so it does not matter how light penetrates the pond, ' he added. Sunlight is required for the formation of fish color pigments. Pigment determines the thickness and brightness of the color arowana. Without enough sunlight, the dragon's pattern faded.

According to Suwandi another role of shading the net is avoiding predators like birds to farms that are close to the forest. The shade nets are worn throughout the year, including during the rainy season. However, in the rainy season the sunlight intensity decreases and the temperature decreases. To keep the water temperature stable, Suwandi overcome it by reducing the volume of water. ' In summer usually the height of pond water 80 – 100 cm, while in the rainy season is lowered to 60 – 80 cm, ' said Suwandi.

Reduced water volume makes sunlight can penetrate to the bottom of the pond so that the water temperature remains suitable for arowana growth. The members of the Osteoglossidae family are still primed even though the pool is not often drained. (Rosy Nur Apriyanti)
