Size structure and gear selectivity of target species in the multispecies multigear fishery of the Kenyan South Coast

Toward Ecosystem-Based Assessment and Management of Small-Scale and Multi-Gear Fisheries: Insights From the Tropical Eastern Pacific

“…These results go in line with a worldwide pattern of fishing that has focused on high trophic levels (Kolding et al, 2015a). MTL values observed here (overall mean: 3.9) are higher than MTL values reported in tropical SSF of the Western Indian Ocean [2.3-3.6, Rehren et al (2018); Tuda et al (2016)], the Caribbean [3.3-3.5, Arias-González et al (2004)], the Indo-Pacific [2.4-3.7, Bacalso and Wolff (2014)] and other localities in the tropical eastern Pacific [2.5-2.9, Zetina-Rejon et al (2003) and Díaz-Uribe et al (2007)]. However, values of trophic level per species used in this study correspond to the adult phase of the species (FishBase, Froese and Pauly, 2017) and do not necessarily correspond to the actual trophic level of the size classes harvested per species.…”

Ecological network analysis metrics: The need for an entire ecosystem approach in management and policy

“…Often fishermen increasingly target the low trophic level species because of their higher overall productivity, which also results in a decrease in MTLC but does not necessarily mean overfishing of the high TL species (Sethi et al 2010, Rehren et al 2018, Tuda et al 2016. Branch et al (2010) show that the negative trend in global MTLC observed at the end of the 1990s is no longer supported by the most recent decades of data.…”

Redistribution of benefits but not detection in a fisheries bycatch‐reduction management initiative

“…; Tuda et al. ). If proposed changes in one gear increase catch in the others, efforts to increase gear diversity, yields, profits, and sustainability will be challenged.…”
