Factors Affecting Productivity and Profitability of Cage-Fish Farming in Siaya County, Kenya

Abstract

Aquaculture is regarded as a critical rural development and livelihood strategy due to its vital role in livelihoods and the economy at large. However, declining capture fisheries from Lake Victoria and low pond productivity have necessitated the development of new culture systems to address the diminishing supply amidst increasing demand. The cage culture system has expanded rapidly and is projected to increase productivity significantly. However, investment in cage-fish farming is often made with little understanding of economic performance. This study aimed to determine the socioeconomic factors affecting the economic performance of cage-fish farming in Lake Victoria. A multistage sampling technique was adopted for the study through purposive sampling followed by simple random sampling to select 298 respondents. A structured questionnaire was used to collect primary data. The socioeconomic factors were determined using descriptive statistics and multiple linear regression. Results indicate that stocking density and fish weight at harvest improved cage productivity and profitability. In contrast, limited sources of capital decreased cage profitability and productivity (P<0.01) due to low operating capital. The size of the cage increased profitability but did not affect productivity. The marital status, and cage site location significantly affect productivity and profitability (P<0.05). This study recommends major interventions focused on improving cage design, stocking density, cage citing, technologies, and innovations in seed and feed production to increase productivity and, profitability. The government should also develop laws and regulations that ensure strict adherence to environmental performance in delineated sites for cage-fish farming.
