| Abstract | Ghana's coast is identified with artisanal fishers who use wooden carved canoes and traditional fishing gears. However, little study has been conducted to assess the performance of this industry in terms of its efficiency. This study aims to analyse the technical efficiency and its determinants of the artisanal fishers in the southern sector of Ghana using the stochastic frontier analysis. The study also identifies and ranks constraints facing the industry using Kendall's coefficient of concordance. Adopting a multistage sampling technique, the study obtains a cross sectional data on 280 fishers from the Greater Accra and Central regions of Ghana. The results demonstrate that crew size, fuel cost, hours at sea and canoe size positively influence output with a return to scale of 1.9. The mean technical efficiency score is estimated to be 0.51 which indicates that averagly the industry obtains 51% of the frontier output. The results also show that the combined effect of operational and industry-specific factors influence technical efficiency although individual effects of some variables are not significant. It is also identified that high cost of inputs was the most important constraints faced by the artisanal fisheries followed by bad weather and activities of trawlers. Availability of canoes is found to be the least constraint facing the industry. The study concludes that the possibility of improving production given the present state of technology and input level can be achieved in the short run by increasing technical efficiency by 49%. |
