This report documents an intervention under the Nutrition-Sensitive Fisheries Management (NSFM) project that aimed to design, implement and evaluate Fish for Improving Nutrition (FIN) training. The FIN training sought to increase awareness of the nutritional benefits of aquatic foods, promote regular inclusion of fish into family diets, particularly for pregnant and lactating women (PLW) and children under 2 years old, and strengthen the ability of communities to improve complementary feeding practices. The training was piloted in the four communities between August and December 2024. Close collaboration with the Ministry of Health (MOH) and local authorities was essential to implement the training, which used innovative and gender-responsive approaches to engage participants and run the training sessions.
