Info

There were reports of the fish causing serious trouble in the country. An experiment was carried out once in seven of the lakes in Kelana Jaya, Selangor, in 2003. Bread was scattered into the water, and to the observers’ horror, most of the fish which arose were Flowerhorn, some of them hideously mutated. Fishes like fighting fish, three-spotted gouramy and snakehead were also badly affected by the release of flowerhorn to the wild. To overcome this situation, equally aggressive local fishes, such as the Giant Snakehead, the Malaysian jungle perch and the Featherback were released into the lakes. This solution seemed to have worked since the Flowerhorn has been reduced and the species affected have begun to recover. 5. Peacock bass (Cichlidae: Cichla ocellaris) The Peacock Bass, or Peacock Cichlid, is a native of South America. It has been introduced deliberately by anglers as a popular game fish into several small ponds and in mining pools at Batu Gajah and Air Kuning in Perak. From Malaysian Fishing Forum it has been reported to be seen in Lake Chenderoh. The threat is that this lake is interconnected to Air Ganda, Bersia and Temengor. This bass is very aggressive, a fast breeder and preys on smaller native fish. It has been identified as a potential cause for ecological imbalance in its adapted habitats. They will only eat live foods. This is a classic case of ecological havoc brought by man when alien species is introduced into a new habitat. 4. Koi (Cyprinidae: Cyprinus carpio) The exact date of Koi or fancy carp (10 varieties) or locally known as ‘kap Jepun’ being introduced to Malaysia is not known. Though it has increased the fishery’s revenue, it has indirectly brought diseases such as Koi Herpes Virus (KHV) to the aquarium industry. KHV is a viral disease contagious to fish and may cause a significant morbidity and mortality in Koi. It was positively identified in Israel in 1998. Since then, other cases have been confirmed in the United States, Europe, Indonesia, Japan and Korea (Kathleen et al 2004, Claudia 2005). KHV disease may cause about 80-100% mortality in affected populations. Since March 2002, KHV has spread to the Asian region with the first infection occurring in Indonesia followed by Japan in October 2003. The DoFM has also detected positive cases for KHV from Ulu Kinta areas in Perak in 2006 by using PCR methods. Its new formal designation is Cyprinid herpesvirus 3 (CyHV-3) by Waltzek et al. in 2005. Peacock bass (Cichlidae: Cichla ocellaris) 6. Aquatic plants They are mainly freshwater types and include water hyacinths or Eichornia crassipes or ‘keladi bunting’ in Malay, can be found floating in rivers and there are plants which are cultivated for decorating aquaria. Some of the aquatic plants (Appendix 4) which command variable commercial values have been reported by Baki et al and Azmi et al (1992). Water hyacinths in hydro-electric dams at Tasik Ringlet, Cameron Highlands, proliferate when not cleared in time could choke up the turbines. Water hyacinths in water supply canals in rice fields also could affect water flow. Japanese Koi Eichornia crassipes (Keladi Bunting) 13
