Title: An adaptive approach to determine landed value for Cape horse mackerel (Trachurus capensis) fishery in Namibia.

This study evaluates the need to review the landed value of Cape horse mackerel while considering the approach and factors that inform it. A literature review highlighted the need for a mixed research method. Quantitative data on fish market value and quota volume were obtained from the Namibia Revenue Agency and FAO, whereas data from the Ministry of Fisheries and industry stakeholders documented the valuation process and perceptions of fairness in the resource rent system. The study found that landed value is determined using local and export market prices, with TRIMMEAN techniques applied to remove outliers before calculating the weighted average price. The final landed value is obtained by subtracting the operating and marketing costs from the average price. While 63% of industry participants viewed the resource rent system as fair for supporting Namibianisation, some called for lower rates on wet landings. Since 2017, rising market prices for Cape horse mackerel have necessitated a revision of the landed value. A collaborative approach, fair methodology, economic considerations, sustainable fishing practices, improved data collection, and regulatory compliance can enhance the valuation process. Additionally, a comprehensive price study and audited income expenditure data can provide reliable insights for reviewing the landed value.
