2. Tilapia (Oreochromis mozambique,O. nilotica) Tilapias were introduced into Malaysia by the Japanese in the 1940s as a cheap protein source (Hickling, 1959). The most popular species for culture is the Nile tilapia, Oreochromis niloticus (Pullin, 1983). Two other species of tilapia used for culture include the Mozambique tilapia (O.mossambique) and the blue tilapia (O. aureus). There have been activities for cage culture of the species in Lake Kenyir by the DoFM and private sectors since two decades ago. The Department has carried out studies on the potential and impact of aquaculture in the lake and has recommended the tilapia as one of the cultured species in the cage as it is technically feasible, economically viable and socially acceptable. The area designated for it is the Sungai Como. A permanent change in ecosystem is unlikely because naturally or biologically tilapia cannot breed in deep water in the lake and they are easily preyed by the indigenous species of the lake such as Baung, Toman and Sebarau. All necessary measures to prevent it from escaping into the lake have been put forward in Good Aquaculture Practices and Skim Pensijilan Ladang Akuakultur Malaysia. hybrid type. Epizootic Ulcerative Syndrome (EUS) was reported from farms in northern states of Peninsular Malaysia which used imported fingerlings of Channa striata and Clarias macrocephalus. 4. The snakeskin gouramy (Trichogaster pectoralis) It is known locally as ‘sepat siam’. This anabantid has been introduced from Thailand as early as the late 19 th century in the Krian rice scheme in Perak (Ang et al, 1989). 5. Pacu (Piaractus brachypomus) It has been introduced and actively promoted by the DoF as red pomfret or bawal merah. This fish is a native of the Amazon and Orinoco river systems of South America and brought to Malaysia in the early 80s for the purpose of culture as both a food and ornamental fish. Research was initiated in 1985 at Freshwater Fisheries Research Centre, Batu Berendam, Malacca with the first successful spawning in 1989 (Mohd. Zaini et al, 1991). Red tilapia, Tilapia niloticus Pacu (Piaractus brachypomus) Black tilapia, Oreochromis mossambique 3. Catfishes (Clariidae: Clarius gariepinus/ lazera) African catfish/sharp-tooth/ Nile catfish) is from Africa in 1988 and hybrid C. macrocephalus x C. gariepinus, Ictaluridae - ictalurus spp. Channel catfish, Pangasidae – pangasius sp, ikan patin. Most of the clarias currently being cultured is of the In Malaysia, the species mentioned above have not been designated as invasive with the exception of the pacu which belongs to the same family as the piranha (Serrasalmus natterei). They have very different behaviour and feeding habits. Unfortunately, the morphological features of both juvenile fish stages are extremely difficult to distinguish, the Government banned the culture of this red pomfret to avoid the possibility of accidental importation of piranha in consignments of the red pomfret seeds. With the successful induced spawning and domestic seed production of red pomfret in 1989, however the Government lifted the ban on the culture of the fish. However, the importation of red pomfret seed is still prohibited. Catfish hybrid, Clarias sp 9

Cobia (Rachycentron canadum) Pacu on sale at one of the markets in Serian, Sarawak The impact from release is not clear but trait show reduced quality of local bred cobia. 6. Japanese eel (Anguilla japonica) About 5,000 Japanese eels fry (elvers) were imported from Japan and Taiwan by the Song Cheng group in 1990s. The world’s largest eel farm was located in Nenasi, Pahang and Malaysia became the 5 th largest producer after Japan, Taiwan, South Korea and China in 1994. Supply of fry depends on wild and this has become the main obstacle in the culturing industry. South Korea and Taiwan have banned the export of elvers. The group now has changed its culture species. 7. Red drum (Sciaenops ocellatus) The fingerlings which were imported from Taiwan had spread red sea bream irido viral disease to sea bass stocks which were kept in cages in close proximity (Oseko, 2004). 8. Golden snapper (Lutjanus argentimaculatus / L. malabaricus) These two species: Lutjanusargentimaculatus (jenahak or) and L. malabaricus (Red snapper or ikan merah) have been brought in from Taiwan and Hong Kong. Cobia (Rachycentron canadum) broodstock 10. White shrimp (Litopenaeus vannamei) The shrimp was introduced from South America into Asia experimentally in 1978-1979 but commercially since 1996 into Mainland China and Taiwan. It has been brought illegally into Malaysia in early 2000s. A ban on it was initiated at first but it has been lifted in 2005. The shrimp has contributed to about 80 percents of the total aquaculture shrimp production (2005). A long with this shrimp a highly mutable virus called Taura Syndrom Virus (TSV) capable of mutating into more virulent strains, able to infect other species 10
