The issues of nutrition insecurity and de?ciencies of micronutrients consumption among households of rural communities in developing countries is widespread and constitute serious public health problem. This study evaluated the nutrition impact of participants and non-participants of an innovation of government regulated (RENLAF) and unregulated (URENLAF) ?sheries in Plateau State, Nigeria. We examine Profit index and nutrition security status of captured ?sheries on data collected from observations made at Catch Assessment Survey (CAS) and a seven- day- food consumption recall. Also through questionnaire from 80 ?shers randomly selected at four lakes (URENLAF) and 30 other ?shers purposively selected from regulated Pandam Lakes. RENLAF Participation has signi?cantly positive e?ects: higher net farm income by N 187,431.28 per month, consumption levels increase by 26%, 79%, 31% and 46% for calorie, vitamin A, iron and zinc. Socioeconomic characteristics such as income, females involved in sales and fishing gears owned and educational status of main female were positive and signi?cantly a?ects nutrition. Hippopotamus and high cost of gears constraints fishing and transformation for higher impacts required educated ?shers, extension education, gear limit, and setting more RENLAF sites from the existing URENLAF sites by rede?nition of property rights.
