To fill the gap, less-preferred pelagic fish species such as Mukene (Rastreneobola argentea) and by-products from filleting Nile perch (Lates niloticus), which were commonly used for animal feeds, are increasingly being minimally processed and marketed for direct human consumption. These fish products constitute what has been termed as ‘low-value fish products’. This study was carried out to assess the nutrient content of low-value fish products (LVFPs) so as to document their potential contribution to protein and micronutrient intake of individuals who depend on these products as their major animal source food.Commonly marketed samples of fresh, smoked, deep fried and sun-dried Nile perch by-products and mukene were collected from factories, by-product processing sites and markets to determine their nutrient contents. The results show that most LVFPs had protein levels comparable to Nile perch fillet but mukene products had the highest crude protein (47.9% to 58.8%), followed by fresh perch eggs products (32.1% to 38.7%). On dry weight basis, the concentration of iron was highest in mukene products (8.18 -10.91 mg/100g) and lowest in perch fillet (1.06 mg/100g); zinc was highest in mukene products (4.07-10.25 mg/100g) and fresh perch eggs (4.07 mg/100g); while calcium was highest in perch skin (1827.4 -1986.3 mg/100g) and mukene products (1556.4-1866.5 mg/100g). Perch fillet was among the products with lowest amounts of iron, zinc and calcium.These findings suggest that LVFPs can improve protein and micronutrient intake of individuals with limited access to animal-source foods. There is need to educate communities to improve processing, handling and acceptability of LVFPs products for direct human consumption. Key words: Low-value fish products Animal-source food Calcium Iron zinc INTRODUCTION mukene (a pelagic fish species), by-products from filleting Analysis of trends in global animal source food these products provide a good alternative source for consumption indicate decreasing fish consumption in protein and micronutrients among populations that developing countries; yet these countries already had cannot access high value animal-source food products low per capita consumption of animal source foods such as mature fish and fillet. [1]. This situation raises concern because less developed Some of the strategies proposed to improve fish countries continue to record high prevalence of supply for human consumption include increased use of undernutrition and this is partly attributed to limited underutilized species and reduction in fish wastage in dietary intake of nutrient dense foods such as form of unintended by-catches and post-harvest losses animal-source food products. This study investigated the [2]. At the moment, the only underutilized fish species in nutrient content of less valued fish products such as the Lake Victoria region are small pelagic fish species Nile perch and juvenile fish in order to determine whether
