“…Perhaps the fast moving and aggressive nature of Cichla as claimed by the anglers in Tasik Telabak (Malaysia) are reasons for its translocation world wide ( Figure 3 ). In addition, C. ocellaris is preferred by anglers because it is less vulnerable (<5 % mortality) to catch-and-release fishing ( Figure 3 ; Shafland, 1999b ; Shafland and Stanford, 1999 ; Cooke and Suski, 2004 ; Holley et al., 2008 ; Rahim et al., 2013 ; Barroco et al., 2018 ; Khaleel et al., 2020 ). In fact, only 97 fish were killed by inexperience hook release where ±2 % of the C. ocellaris deaths occurred after lethal hook puncture to the gills ( Thomé-Souza et al., 2014 ; Bower et al., 2016 ).…”

Peacock bass (Cichla spp.) originates from the Neotropical environments of Brazil and Venezuela but, through trade and smuggling for aquarium keeping, sport fishing and aquaculture, it is now an emerging concern. Yet, less is known for Cichla spp. distribution and its ability to invade new environments. Aimed to communicate on Cichla spp. ecology, biology and introduction schemes from Scopus, Web of Science, Google Scholar and also National Centre for Biotechnology Information, this review also contains management strategies for invading fish species. While Cichla spp. can displace native fish populations, this concern is explained using ecological functions, physiological demands, direct and secondary invasion, disease tolerance and parasite spillover. Briefly, Cichla spp. has rapid embryogenesis (72 h) and matures in short periods (11-12 months), giving it an advantage to colonize new environments. With a large appetite, this true piscivore gains territorial control over water bodies by making it their feeding and nursery grounds. Perceived as an emerging concern after becoming introduced, seal-off or sport fishing were used to manage Cichla spp. but, this practice is not sustainable for the entire ecosystem. Hence, we recommend bottom-up management that involves community participation because they interact with the fish and have knowledge about their environment.

“…The peacock bass was first recorded in Perak, West Coast of Peninsular Malaysia in the early 1990s [2]. Since then, it has been reported and expands to different freshwater bodies across Peninsular Malaysia [3][4][5][6]. Although the introduction was well intended by anglers, Cichla spp.…”

The introduction of invasive Cichla spp. was followed by the several reports regarding the decline of local freshwater native species in Malaysia. The purpose of this research was to generate information concerning the introduction history of Cichla spp. in Malaysia. Studies on genetic diversity and structure provides the essential baseline data for monitoring and conservation of invasive species. This will help to clearly understand the propagule pressure and genetic distribution of Cichla spp. in the invaded freshwaters of Malaysia. A total of 61 samples of Cichla spp. were collected from 9 sampling location in Malaysia for mitochondrial DNA (control region) analysis. Overall samples showed high genetic diversity (Hd, 0.6700; π, 0.0254) and yielded 9 haplotypes resulted from different Cichla spp. present. The maximum likelihood tree with strong bootstrap support revealed that Cichla spp. forms 3 clusters, and confirmed to be C. monocoulus, C. occelaris and C. temensis. Except for Malacca populations, other populations were largely dominated by either C. monocoulus or C. occelaris. The current study suggesting that more than one introduction event of invasive Cichla spp. occurred in Malaysia. HIGHLIGHTS One of the common problem in the conservation effort for Malaysia’s freshwater aquatic ecosystem is failure to understand the introduction events of invasive species (Cichla) Mitochondrial DNA analysis (control region) conducted in order to find the genetic diversity and genetic structure of invasive Cichla across freshwater habitats in Malaysia High genetic diversity was observed, suggesting multiple introduction occurance of invasive Cichla in the country GRAPHICAL ABSTRACT

Malaysia is recognised among the mega-diversity countries with the abundance of various freshwater species. Malaysian freshwater biodiversity is under threat after the introduction of an invasive peacock bass. The presence of this predator could challenge the coexistence of the native species. In the current review, the most important aspects regarding peacock bass threats to the biodiversity future of local species are addressed. Four non-native species of peacock bass are presently recognised in Malaysia. To date, the peacock bass species expand to all parts of Peninsular Malaysia with no records yet found in Kelantan and Borneo. Invasion success is more susceptible in Malaysian lakes (84.38%) compared to the dams, rivers and reservoirs. The mode of rapid expansion of this species is highly connected to the sport fishing and anglers. A propagule pressure, favourable habitat, prey abundance and feeding behaviours are responsible factors for the successful establishment of this species in Malaysia. The species are generalist feeders and piscivorous in nature. It is difficult to eradicate peacock bass since it provides physical jobs (recreation and tourism). However, the damage the species will cause in future is unpredictable. At this point, proper management of this species must be implemented to reduce its population. This could be achieved through updating checklists of freshwater bodies, improving monitoring systems and public awareness.
