Alien Fish Species

River pollution has been a major problem in Malaysia and significantly affects the environment. One of the contributing issues would be the spread of invasive alien fish species that has given negative impacts on the environment and ecological disaster, the human health, harming the native animals and plants, as well the economy. Based on the National Committee on Invasive Alien Species Report in 2018, that 46 invasive alien species from a total of 130 species in the established main invasive alien species lists in Malaysia.  The alien fishes have been known to make their presence in our dams, lakes and rivers but not much attention has been paid to their existence. Based on these facts, it is proven that the issue poses a significant risk hence an urgent attention is required in managing this pollution through proactive legal measures to enforce strictly the existing law so as to prevent the halt of the spread of invasive species. A legal doctrinal and non-doctrinal modes of research are used to examine and review on the existing laws and/or policy governing this issue. This research will help to provide reference and strategic planning via legal approach for better controlling the invasion in our Malaysian waters.

Glochidia (parasitic larvae) of freshwater mussels generally require a fish as a host. Westralunio carteri Iredale, 1934 (Bivalvia : Hyriidae), the only freshwater mussel found in south-western Australia, was listed as Vulnerable, but recently changed to Least Concern (International Union for the Conservation of Nature). Glochidia were found on four alien and seven native species of fish from 18 sites in the South West Coast Drainage Division. On alien fishes, prevalence of glochidia ranged from 0.0 to 41.0% and mean intensity (number of glochidia per infested fish) from 1.0 to 6.0, while on native fishes prevalence was 9.2–90.5% and intensity was 2.3–7.1. Glochidia infestation was greatest on benthic fishes, which may be a consequence of greater encounter rates, but other factors, such as host size, probably also influence glochidia prevalence and intensity. Glochidia were generally restricted to fins of infested fish, and were rarely on gills or the body surface. In the laboratory, four native and one alien fish species were found to be competent hosts for their ability to produce juvenile W. carteri, but two alien fish species were not. The inability of some alien fishes to produce juvenile W. carteri could potentially reduce recruitment success in areas dominated by alien fishes.

Interaksi trofik pasca masuknya ikan introduksi ataupun ikan asing invasif merupakan dasar untuk mengkaji tekanan ekologis terhadap ikan asli. Penelitian ini bertujuan untuk menganalisis interaksi trofik komunitas ikan pasca berkembangnya jenis-jenis ikan asing invasif di Danau Matano, Sulawesi Selatan. Ikan contoh diperoleh dari hasil tangkapan jaring insang percobaan, jala lempar, dan seser pada Mei, Oktober, dan November 2015 serta Februari, Juli, dan September 2016. Analisis ekologi trofik yang dilakukan meliputi indeks bagian terbesar, tingkat trofik, luas relung dan tumpang tindih relung makanan, serta pola strategi makan. Hasil penelitian menunjukkan komunitas ikan yang tertangkap di Danau Matano terdiri atas 9 famili, 11 genera, dan 17 spesies. Ikan louhan mendominasi komunitas ikan di Danau Matano sebesar 53,62%. Makanan alami yang banyak dimanfaatkan oleh sejumlah ikan dalam komunitas adalah insekta (Diptera), Gastropoda (Tylomelania sp.), dan larva insekta (Chironomidae). Kelompok trofik komunitas ikan di Danau Matano terdiri atas detritivora, herbivora, insektivora, zoobentivora, dan piscivora. Masuknya ikan introduksi memunculkan kelompok trofik baru (detritivora dan herbivora). Ikan introduksi cenderung memiliki luas relung makanan yang lebih bervariasi. Kompetisi terhadap makanan alami kategori moderat banyak terjadi antara ikan asli dengan louhan. Strategi pola makan ikan asli di Danau Matano cenderung bersifat spesialis, sedangkan ikan introduksi memiliki strategi pola makan yang lebih bervariasi dan oportunistik. Ikan louhan sebagai ikan introduksi dominan yang bersifat invasif mampu memanfaatkan seluruh sumber daya makanan alami yang tersedia dan menempati tingkat trofik tertinggi di Danau Matano. Tekanan ekologi terhadap ikan asli oleh ikan asing invasif di Danau Matano terjadi karena adanya kompetisi terhadap makanan alami.Trophic interactions post-develpment of non-native fish or invasive alien fish species are the basis knowledge for assessing and preventing the ecological pressure on native fish. This research aims to analyze the trophic interactions of fish community post-development of invasive alien fish species in Lake Matano, South Sulawesi. Fish samples were obtained from the catch of experimental gill nets, cast nets, and push nets in May, October, and November 2015 along with February, July, and September 2016. Trophic ecological analysis carried out included index of preponderance, trophic level, niche breadth and niche overlap of natural food, and feeding strategy. The fish community caught in Lake Matano consists of 9 families, 11 genera, and 17 species. Flowerhorn cichlid dominates the fish community in Lake Matano by 53.62%. Natural foods that are widely used by a number of fish in the community are Insecta (Diptera), Gastropods (Tylomelania sp.), and larvae of Insecta (Chironomidae). The guild trophic of fish community in Lake Matano consists of detritivores, herbivores, insectivores, zoobentivores, and piscivores. The introduction of non-native species bring up to new guilds (detritivores and herbivores). Non-native fishes tends to have a variety niche breadth. Moderate competition for natural food resources between native fish and flowerhorn cichlid is quite high. Feeding strategy of native species in Lake Matano tend to be specialist, while non-natives species have more variety and opportunistic. Flowerhorn cichlid as dominant invasive alien fish species is able to utilize all natural food resources and occupies the highest trophic level in Lake Matano. Ecological pressure on native fish by invasive alien fish species in Lake Matano occurs due to competition in obtaining natural food resources.
