Population dynamics of sailfin catfish (pterygoplichthys sp. Hancock, 1828) in sidenreng lake water, Sidenreng Rappang District, South Sulawesi

Understanding feeding competition under laboratory conditions: Rohu (Labeo rohita)versus Amazon sailfin catfish (Pterygoplichthysspp.)

“…Our study demonstrated that feeding behavior of catfish is mostly associated with aggression (Hossain et al, 2018; Umar and Ramayani, 2021), which is characteristic of both fingerling and large-size classes, and is displayed towards conspecifics and hetero species, as well. Though there was a reduction in aggressive behavior of catfish towards rohu fingerlings when compared to aggression shown towards conspecifics (in C and SC trials) or large-size rohu (in C/R trials).…”

“…The Amazon sailfin catfish is native to the Amazon basin, and has been tagged as one of the invasive species in several countries, Mexico (Wakida-Kusunoki et al, 2007), Florida (Ludlow and Walsh, 1991), Texas (Edward, 2001), Malaysia (Saba et al, 2020), Iraq (Qasim and Jawad, 2022), Vietnam (Levin et al, 2008), Philippines (Jumawan et al, 2011), Sri Lanka (Herath et al, 2020), Italy (Piria et al, 2018), Bangladesh (Hossain et al, 2018), and the Indian freshwaters (Bijukumar et al, 2015; Rao and Sunchu, 2017; Hussan et al, 2019; Das et al, 2020; Seshagiri et al, 2021, Mallick et al, 2023). Amazon sailfin catfish is a benthic forager with hard armor and spines, belonging to the Loriicariidae family of catfish, which are considered to be aggressive and territorial (Hossain et al, 2018; Umar and Ramayani, 2021). Moreover, several species of catfish, for example, “ multiradiatus ”, “ pardalis ”, “ disjunctivus ”, belonging to the genus Pterygoplichthys have been introduced in different freshwater habitats across the globe (Singh and Lakra, 2011; Sumanasinghe and Amarasinghe, 2014; Tarkan et al, 2017).…”
