Valuation of fishery among artisanal bait fishers that use non-commercialized intertidal bait at the Mida Creek, Kenya

Abstract

Humanistic valuation of resources is critical to understanding drivers to patterns and impacts, however, value of non-traded intertidal tropical bait, such as polychaetes and hermit crabs, used by artisanal fishers, is unknown. Bait harvested from intertidal habitats and used for fishing at Mida Creek, were quantified, and variable and fixed cost incurred determined, income and profitability, were computed and compared. Fishers harvest and use 58 baits pieces, to land 2.4 kg of fish with an average earning of 3.8$.d-1. Bait values were similar among bait types and sites, but income (3.3$), earning (4.1$) and profitability (255%), were significantly higher for polychaete bait fishers. This was attributed to lower bait harvesting and fishing expenditure. Bait fishery is a labour intensive, and profitable enterprise, that is, however, comparable to semi-skilled wage livelihood options, in the region. Improvement in profits, may be achieved by increasing fishery yield, by adoption of alternative fishery and livelihoods.
