Impact of Socio‐Demographic Factors and Handling Practices on Post‐Harvest Fish Losses in Kakamega County's Cultured Tilapia Value Chain

Aquaculture Fish and Fisheries, Journal Year: 2025, Volume and Issue: 5(1)

ABSTRACT Post‐harvest fish losses (PHFL) significantly impact the aquaculture sector in Kenya, undermining food security and economic growth. This study investigated socio‐demographic factors handling practices influencing PHFL Kakamega County's cultured tilapia value chain. Data were collected from 94 chain actors operating across multiple nodes, including farming, processing retail stages six sub‐counties using surveys observations. Results revealed that 64% of participants female, 40.3% had completed high school, with only 26.6% holding valid handler certificates. Household sizes mostly ranged 4 to 9 members, experience varied, 33% having 5–10 years 17% over 21 experience. significant farm gate highest Butere (32%) lowest Likuyani (8.42%). Wholesale also notable, Mumias East showing overall losses. Regression analysis identified key predictors PHFL, poor sanitary conditions, lack training, inadequate water quality cooling practices, explaining 87.2% variance PHFL. Experience negatively correlated ( r = −0.354, p < 0.01), indicating more experienced individuals incurred lower Chi‐square tests showed associations between like household size, occupation, training sanitation but not gender, education or age. The findings highlight need for targeted interventions, programmes, infrastructure improvements adherence safety standards, minimise improve enhance nutrition County.

Biosecurity protocols and fish health management in Kenyan fish hatcheries: a key to sustainable production of quality fish seed

Aquaculture, or aquafarming, is increasingly becoming a vital farming activity globally to meet exponentially high demand for fish and reduce pressure on global capture fisheries. In Kenya, aquaculture growth has led concerns over the supply of quality seed, with farmers often reporting involving fingerling adulteration mislabelling where frog tadpoles are packed supplied as Clarias gariepinus fingerlings mixed-sex Oreochromis niloticus falsely sold sex-reversed monosex Nile tilapia. This study aims identify strategies enhance seed production in country. Primary data were collected via questionnaires interviews using Kobo toolbox. Respondents selected through purposive random sampling. The SPSS software was used analysis. Findings showed moderate reliance specific offices disease cases significant variation types bio security measures. Fish treatment management practices more engaged by hatchery operators than reporting. No differences found between management, type diseases encountered at hatchery, nature produced (p > 0.05). However, there difference source broodstock, biosecurity measures, encountered, Disease Case Reporting Office < measures period when established Lack financial support, inexperienced workforce, lack knowledge identification major problems affecting sustainability operations Aquaculture policymakers should establish support hatcheries, implement training, promote research collaborations surveillance, incentivize among managers improve Kenya. Further explore methods long-term mitigate risks.
