Abstract
  • This paper will present some preliminary result from a study of post-harvest losses in the Sri Lanka tuna value chain. Fish losses refer to the decrease in edible fish mass throughout the part of value chain that specifically leads to edible food for human consumption. Sri Lanka is a unique player in international tuna market but is suffering from postharvest losses in term of quality degradation throughout the value chain. Focusing these losses is of high importance to improve the incomes and the nutritional security of the domestic consumers and combating hunger. This study will estimate the actual losses and, the reason the losses, the environmental impacts and solutions to minimize the losses. The principal focus is to analyse the resource utilization in the value chain from boat to folk (fishing, transport, handling, processing, distribution and consumption) and the environmental performances. Life Cycle Assessment is used as a key tool for the assessment. Global worming potential is considered environmental impact categories and assessed in qualitative way. Possible solution of the food losses is discussed from the point of view of the fishing vessel to the retailer in terms of wasted natural resources and unnecessary carbon and water foot print, impact on biodiversity in production of tuna products
