Description Small indigenous fish species (SIS) such as mola (Amblypharyngodon mola) regarded as natural ‘superfoods,’ due to their high nutrient content, offer a promising avenue for addressing the nutritional deficiencies in India. Over the past decade, integrating mola into conventional carp polyculture systems has emerged as a promising nutrition-sensitive innovation, significantly enhancing micronutrient intake, particularly for women and children. However, the lack of hatchery-reared mola seed has hindered the sustainability of this approach. Recently, this bottleneck was addressed by developing a hatchery-based mass seed production protocol for mola, which was introduced into carp farming systems on a pilot basis. This study evaluates the performance of hatchery-produced mola seed inhomestead carp polyculture ponds in Odisha, India by using a field survey. Of the surveyed farmers, 24% purchased mola spawn, while 76% opted for mola fry. The average pond size of surveyed farmers was 0.32 ha with an average culture duration of 9months. Farmers stocked mola spawn at an average density of 283,583/ha and fry at 22,190/ha. Results showed that 93% of farmers achieved successful mola production, with an average mola yield of 194 kg/ha and total production of 2831 kg/ha. Molacontributed an average of 9% to the total fish production reaching a maximum contribution of up to 26%. The mola fish contributed significantly to the household in terms of additional revenue. Household consumption averaged 14 kg of mola per year, with a per capita consumption of 3 kg. Increasing pond size and optimizing stocking density emerge as critical factors positively impacting mola production and income. Overall, this study demonstrates the potential of hatchery-produced mola seed in promoting nutrition-sensitive aquacul-ture in Odisha, offering valuable insights for its scaling up.
