“…The late 1990s and 2000s saw the dominance of Caridina nilotica and haplochromines in the diet, the reason being that Nile perch predation on R. argentea was reduced when their preferred prey (haplochromines) are plentiful (Nyamweya et al . ). Increased haplochromines in perch diet are attributed to a resurgence of the species after the decline of Nile perch, although the dominance of C. nilotica in their diet could be attributed to increased hypoxia in the lake.…”

“…Despite the increasing effort, Nile perch catches have remained stable after the Nile perch boom, indicating fishing pressure may not be the only driver of the species’ abundance in Lake Victoria (Nyamweya et al . ). The Food and Agricultural Organisation (FAO) of the United Nations calculated that the boom created 180,000 jobs in the fishing industry in the 1980s alone.…”

“…To meet these needs, recent investigations have constructed ecosystem‐level models for evaluating freshwater and marine communities around the globe (Nyamweya et al 2017; Sturludottir et al 2018; Fay et al 2019). For example, food web models leveraging the results of observational or experimental studies have often been used to enhance understanding of the structure of an ecosystem and identify leading indicators or nodes most sensitive to perturbation spanning multiple levels of biodiversity (e.g., genes, species, guild; Masi et al 2017; Sturludottir et al 2018; Fu et al 2019; Hansen et al 2019).…”

“…End‐to‐end ecosystem modeling approaches, which seek to represent all components of socio‐ecological systems, have enabled comparisons of system‐level outcomes from different scenarios and cost–benefit analyses of management actions (Beaugrand 2014; Möllmann et al 2015). Such models have served as tools to explore the socioeconomic implications of changing ecosystem structure (Fay et al 2019), evaluate resource management strategies (Nyamweya et al 2017), and project the impacts of future climatic and harvest scenarios (Olsen et al 2018). For example, Fay et al (2019) modeled the northeastern United States and found that changes in fishing effort led to strong responses, with clear tradeoffs among species and fishery sectors, but that regional market sales scaled nonlinearly with total landings, and regional income was relatively similar across scenarios.…”

“…It has been used to test a number of management scenarios for different areas. It has, for example, been used to test management scenarios with different discarding regulations (Fulton et al 2007), scenarios of gear shift to reduce by-catch (Kaplan et al 2012) and different fishing pressure scenarios (Nyamweya et al 2017).…”
