Fish food webs in a South African estuary: a spatial and temporal assessment

Feeding habits and seasonal trophic guilds structuring fish community in the bay mouth region of a tropical estuarine habitat

“…Fish trophic studies in the estuarine ecosystem have long been conducted worldwide. These include trophic relations of fish in South African estuaries (Whitfield, 1980; Whitfield, 2020b), Guadalquivir Estuary (Baldo & Drake, 2002), the eastern boundary of the San Francisco Estuary (Grimaldo et al ., 2009) and the Chesapeake Bay (Buchheister & Latour, 2015). Some studies have assessed the feeding ecology of fishes in different types of ecosystem (Braga et al ., 2012; Elena et al ., 2020), such as the abyssal and hadal zones of Kermadec and Mariana Trenches (Gerringer et al ., 2017), reef fish in a remote oceanic island at the Juan Fernandez Archipelago, Chile (Ramírez et al ., 2013), the largest hypersaline Araruama Lagoon on the east coast of South America (Almeida‐Silva et al ., 2015), northeast Brazil (Pereira et al ., 2016), the rocky reefs in Australia (Truong et al ., 2017), the Little Colorado River, Arizona (Behn & Baxter, 2019) and the North Yellow Sea, China (Rongliang et al ., 2021).…”
