“…Indeed, there is a growing body of work that links Nile tilapia introductions with substantial ecological disturbances through the alteration of aquatic ecosystem function, for example, eutrophication, changes in community structure, and even local extinction of native fish populations (Figueredo & Giani, 2005;Olden, Jackson, & Peres-Neto, 2001;Starling et al, 2002). Tilapia also exploit trophic resources that are not being used by the native fishes (Henson, Aday, Rice, & Layman, 2018) and have high invasive potential in the Americas (Cassemiro, Bailly, & Graça, 2018).…”

Nile tilapia (Oreochromis niloticus) invasions disrupt the functional patterns of fish community in a large subtropical river in China

Although non‐native species can modify ecosystem function, their effects in southern China have not been investigated, despite their ecological importance. This study assessed how Nile tilapia Oreochromis niloticus (L.) invasions impact the functional patterns of fish communities in the large subtropical Pearl River by analysing the relationships between invasion and body size over a 9‐year period. The relative abundance of Nile tilapia increased significantly over time. In particular, the established Nile tilapia significantly undermined the relative densities and the body size of the native fishes. Importantly, this study provided empirical evidence that functional indices (such as body size) are more sensitive when evaluating the effects of non‐native species on a community than richness. Understanding processes such as those should be the basis of controlling alien fish species and fisheries management in the Pearl River.

“…7. This is of concern since tilapiine cichlids, for example, members of the genera Coptodon, Oreochromis, and Tilapia, are the most widespread group of non-native fishes worldwide (Canonico et al 2005, Cassemiro et al 2018, presently cultured in most reservoirs of South America (Lima Junior et al 2018).

“…An occasional spillover of these fish downstream threatens ecosystems given the role of M. salmoides as a keystone group (Blois et al 2013, Pinnegar et al 2014. This is of concern since tilapiine cichlids, for example, members of the genera Coptodon, Oreochromis, and Tilapia, are the most widespread group of non-native fishes worldwide (Canonico et al 2005, Cassemiro et al 2018, presently cultured in most reservoirs of South America (Lima Junior et al 2018). Such introductions are huge in Brazilian freshwaters since the 1970s (Ortega et al 2015) and now achieved a critical stage in which they should be monitored in water quality assessments (Gondwe et al 2011).…”

Benthification, biotic homogenization behind the trophic downgrading in altered ecosystems

et al. 2019

Several dozen fish species have been introduced into Neotropical waters, causing significant biotic changes that include deterministic predation interactions with ecosystem effects. In general, reservoirs are preferred over lakes as places for stocking policies, due to their artificial aspect, consequently promoting fish introductions. In a meta-analytic approach, we compared the biomass of plankton-feeding (and top predators) with bottom-feeding fish species between reservoirs and lakes, considering the influence of invaders and trophic levels. Among the 26 ecosystems (12 reservoirs and 14 lakes), there is a dominance of non-native bottom-feeding species in artificial environments. We revealed a mechanism behind this dominance in a study case, a tendency for trophic downgrading and biotic homogenization based on interactions between an expatriate invasive centrarchid (sunfish family) predator from North America (the largemouth bass Micropterus salmoides) and two omnivorous cichlids from Africa in novel environmental contexts in Brazil (the benthification process). Both juvenile and adult largemouth bass are keystone predators in aquatic food webs in both their native and introduced ranges. The omnivore-detritivore tilapiines Oreochromis spp. and the phytophagous-omnivorous Coptodon spp. are species that exhibits strong generalist tendencies. Such species feed on the omnivore and detritivore compartments, enhancing detritus cycling among a large variety of d 13 C sources. Since their consumption is disproportionate, facilitation of other species occurs with multiplicative effects in the environment. Interactions between invasive species, that is, when an invasive predator (bird, fish, or invertebrate) eats an invasive prey (mainly fish and invertebrates), can serve to highlight biotic homogenization on fresh waters.

Tilapia fisheries in Guangdong Province, China: Socio‐economic benefits, and threats on native ecosystems and economics

et al. 2019

Tilapia is one of the groups of fish species most widely cultured globally. China has been the largest producer of tilapia in the world since 1990s. Guangdong Province produces almost 40% of all tilapia in China because of its suitable geography and weather conditions, and tilapia culture has brought considerable economic benefits. Unfortunately, many of the biological traits that make tilapia popular for culture also contribute to its success as an invader. Tilapia has invaded natural waters and has become the dominant fish in many rivers of Guangdong Province, causing economic loss in capture fisheries, and affecting native fish species, biodiversity and aquatic ecosystems. Poor fishery management, water quality degradation and biodiversity loss have all facilitated the tilapia invasion. Tilapia have filled the niches left vacant by now locally extinct native species resulting from environmental changes in freshwater ecosystems of the province. The introduction of tilapia has both advantages and disadvantages, which should be managed to use effectively the various tilapia species in aquaculture while controlling their spread in natural waters.
