“…Additionally, experienced fishers are more informed about marketing and potential buyers, thus selling their catch in a short time. The findings of this study are in agreement with related studies in Nigeria ( Adelaja et al., 2018 ) and Bangladesh ( Acharjee et al., 2021 ). Training improves access to credit and value-addition initiatives ( Akanni, 2010 ).…”

“…The spoilage process of fish starts within 12 h of their catch ( Berkel, 2004 ). High ambient temperatures such as 20 °C and above create favourable conditions for fish spoilage by increasing lipid oxidation and microbial activity ( Ghaly et al., 2010 ; Adelaja et al., 2018 ). In some regions, the spoilage tends to be higher during the rainy season because drying fish is extremely difficult during this season ( Akande and Diei-Ouadi, 2010 ; Assefa et al., 2018 ).…”

“…Fishers who have been working for a long time in the fisheries sector have acquired skills through work. The skills enable them to handle fish properly to reduce bacterial contamination and other losses ( Adelaja et al., 2018 ). Additionally, experienced fishers are more informed about marketing and potential buyers, thus selling their catch in a short time.…”

“…Education reduces post-harvest fish losses in Ghana ( Gyan et al., 2020 ) and Bangladesh ( Acharjee et al., 2021 ). Educated people are eager to learn and adopt good practises for handling fish to reduce losses ( Adelaja et al., 2018 ). However, the fishers with primary education in this study reported lower levels of spoilage.…”

“…Findings of this study in line with the findings of ( Tesfay and Teferi, 2017 ) conducted in Ethiopia in identifying causes of PHL (high environmental temperature, harvesting immature fish, the presence of predators, loss of fish in the Lake with the net, high flooding, and delay before marketing). These factors were also reported elsewhere as essential causes of PHL ( Adelaja et al., 2018 ; Bengwe and Kristófersson, 2012 ; Olusegun and Mathew, 2016 ; Ward, 1996 ). All these causes (high environmental temperature, harvesting immature fish, the presence of predators, loss of fish in the Lake with the net, high flooding, and delay before marketing) can lead to a physical loss of product which further leads to a penalized market value ( Ahmed, 2008 ).…”

Fisheries play a significant role in food security, livelihood, and source of income in developing countries. The annual fish production potential of Ethiopia reaches up to 51, 000 tones, however, the actual production is much less than the potential that the country has. The fisheries sector of Ethiopian is not well developed regarding pre and post-harvest handling practices. Besides, post-harvest loss in the fisheries sector is not yet well-studied. This study objective aims to assess causes and extent of post-harvest loss associated with fish in Lakes of Hayq and Tekeze. Post-harvest loss assessment was conducted using a simple random sampling approach from October 2017 to May 2018. The study was conducted based on FAO recommendations of qualitative and quantitative field assessment methods. These methods include Informal fish loss assessment method (IFLAM), load tracking (LT) and the questionnaire loss assessment method (QLAM) methods were used to assess the causes and to estimate the amount of PHL of fish. The data generated by these methods were analyzed descriptively as well as a GLM model was used to understand the causes of fish loss in the two study lakes. A total of 140 randomly selected participants were included in the interview process. From these participants, 85 of them were from lake Tekeze while the rest were from Hayq. Results indicate that high environmental temperature, absence or delayed marketing, harvesting immature fish, predators, and flood are the most important causes of post-harvest loss of fish in the two Lakes. Besides a GLM model predicted that study lake, boat type used, boat ownership, species of fish harvested, preservation method used, distance to market (Km), Maximum catch/day (Kg), Minimum catch/day (Kg), and Fishing experience were essential predictors for post-harvest loss incurred by fishermen on daily basis. Based on secondary data from agricultural office, the monetary value of the post-harvest loss of fish was estimated to be 10,934,000 Ethiopian birrs (397,600 USD) for the last six years in the study areas. A considerable product loss in the fisheries sector indicates the need for intervention by stakeholders. Provision of support services and assets such as freezers, electricity generators, boats, legal net and on job training about proper handling practices may play a tremendous role in decreasing post-harvest loss in the fisheries sector of the study areas.

This review was aimed to summarize the extent and causes of fish post‐harvest losses (FPHLs) in Sub‐Saharan African (SSA) countries and suggests the necessary intervention measures to narrow the gap between demand and supply. Globally, an estimate of 10–12 million tons of fish is lost per year. FPHLs in SSA are higher than those in other parts of the world. In SSA, the values of fisheries are estimated at 24 billion USD, 1.26% of the GDP of all the African countries and 6% of agriculture GDP. The vast majority of FPHLs in SSA occur at the production (39%), handling (36%), distribution (13%), processing (7%) and consumption (5%). The major factors that cause FPHLs in SSA were long time spent in hauling of fishing gears, spoilage, size discrimination, species preferences, operational losses, animal predation, poor handling practices, lengthy duration of fishing cycle, failure to use ice, lack of storage facilities, lack of transportation and insect infestation. FPHLs amount one third of total production and financial losses of 2–5 billion USD in SSA countries. Furthermore, volarization of fish waste and converting waste into useful substances is a promising approach to reduce fish waste. It can be recommended that improving fish production, live fish handling, processing, preserving, and marketing in SSA could narrow the gap between fish demand and supply.
