Shifts in composition of fish species of fishery in Lake Naivasha, Kenya: Trend implications for fishing effort, yields and revenue

Abstract

Fishery resources are an essential component of the socioeconomic development of many countries, especially developing countries, because they provide a source of nutrition and food security, employment and livelihood opportunities for the local communities (Welcomme et al., 2010; Youn et al., 2014). Inland waters are endowed with high (>12,700) fish species diversity (Funge-Smith, 2018), supporting local livelihoods and food security in many nations. Globally, inland water fish captures have exhibited a steady yearly increase, with over 12 million tonnes reported in 2018 (FAO, 2020). The FAO indicated that nations endowed with important water bodies and river basins have inland captures more concentrated than marine captures. Of the total global inland capture fishery production, Asia
