A GIS‐based approach for delineating suitable areas for cage fish culture in a lake

Abstract: We present a GIS‐based approach to the delineation of areas that have different levels of suitability for use as tilapia cage culture sites the Kenyan part of Lake Victoria, Africa. The study area was 4,100 km2. The method uses high‐resolution bathymetric data, newly collected water quality data from all major fishing grounds and cage culture sites, and existing spatial information from previous studies. The parameters considered are water depth, water temperature, levels of dissolved oxygen, chlorophyll‐aconc… Show more

“…Notably, a substantial portion of the Mwanza Gulf, ∼58.06%, was deemed unsuitable for fish cage culture installation due to constraints arising from multiple factors. This outcome aligns with findings from other regions, including Lake Victoria in Kenya (Aura et al., 2021), and various other studies (Asmah et al., 2021; Njoku et al., 2022; Ross et al., 2011). The limited extent of suitable sites identified by the overall model is attributed to its comprehensive approach to fish cage site selection.…”

“…After transforming the datasets to a comparable scale, the next step was to estimate the weights for each criterion. The authors of this article (modellers) consulted 40 stakeholders with different interests in cage fish farming, following a practice suggested in previous studies on site selection (Aura et al, 2021;Ross et al, 2011Ross et al, , 2013Soto et al, 2008) and EAA (Telfer et al, 2013). The stakeholders used in this study included fishers (9), fish cage farmers (6), aquaculture and ecology experts from TAFIRI (2), environmental experts from Lake Victoria Environmental Management Program (LVEMP) (2), Fisheries officers from District Councils (4), wildlife conservationist from Saanane National Park (2), environmental specialists from the Tanzanian Lake Victoria Basin Water Board (LVBWB) (2), ferry operators (4), Tanzania Ports Authority (TPA)-Mwanza Office (2), Police and Military officers (3), water quality technicians from Mwanza Urban Water Supply and Sanitation Authority (MWAUWASA) (2), and Kahama-Shinyanga Water Supply and Sewerage Authority (KASHWASA) (2).…”
