Identification of wild tilapia species in the main rivers of south China using mitochondrial control region sequence and morphology

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

“…Although more than eight tilapia species have been cultured in Guangdong, only five (blue tilapia, Nile tilapia, redbelly tilapia, mango tilapia and a hybrid of Nile tilapia) are known from rivers of the province (Gu et al., ); of these, Nile tilapia and redbelly tilapia are the most common (Figure ); and hybrid Nile tilapia is counted as Nile tilapia.…”

“…Although more than eight tilapia species have been cultured in The widely distribution of Nile tilapia may be correlated with its popularity in aquaculture (Gu et al, 2016). Redbelly tilapia, which was not popular in aquaculture because of its slowly growth and smaller body size (Fang, 2015;He, Lin, Sun & Zhang, 2013), is also widely distributed, possibly due to its higher reproductive rate and cold-temperature tolerance (Gu et al, 2016;He et al, 2013). Nile tilapia is more abundant in southern and western parts of Guangdong Province, whereas redbelly tilapia is more abundant in the colder eastern and northern areas (Gu et al, 2016).…”

The current distribution of invasive mrigal carp (Cirrhinus mrigala) in Southern China, and its potential impacts on native mud carp (Cirrhinus molitorella) populations

“…Fierce competition as a consequence of niche overlap has been described between native and invasive species (Qin 2005). Invasive species often displace native fauna with similar niches by competing for resources and habitat (Taniguchi et al 1998;Jia 2005;Blanchet et al 2007;Martin et al 2010;Gu et al 2016). Interspecific relationships between fishes with niche overlaps have been the focus of a number of studies (Wu 2001;Li et al 2012).…”

Temperature effects on the distribution of two invasive tilapia species (Tilapia zillii and Oreochromis niloticus) in the rivers of South China

“…In fish communities, successful invaders may outcompete native species for food and habitat, which affects the native species' habitat selection, food choices, and apparent survival (Blanchet et al 2007;Martin et al 2010;Gu et al 2015;Raymond et al 2015). Although many studies have highlighted the competitive interactions between alien and native fish species in freshwater communities, there is a general lack of understanding of the interactions between different alien species (Taniguchi et al 1998;Blanchet et al 2007;Martin et al 2010;Kornis et al 2013;Raymond et al 2015;Gu et al 2016). In many cases, invasions by alien species involve multiple closely related fish, such as different Asian carp or tilapia species; however, less attention has been given to the competitive interactions between different alien species (Irons et al 2007;Wu and Yang 2012;Zengeya et al 2015;Gu et al 2016).…”

“…Tilapia (Oreochromis mossambicus) were first introduced to South China in 1957; since then, more than seven tilapia species have been introduced to China (Zhu et al 2008). To date, five tilapia species (O. aureus, O. niloticus, Tilapia zillii, S. galilaeus, and a hybrid of O. mossambicus and O. niloticus) have been identified in the rivers of South China (Gu et al 2016). Among these species, O. niloticus and T. zillii are most common, and they were both introduced to mainland China in 1978 and widely distributed in the study area (Gu et al 2016(Gu et al , 2018.…”
