The contribution of homestead pond fish culture to household food security and dietary diversity in central coast of a developing country

Fish farming in homestead ponds help alleviate poverty, provide animal source food, micronutrients, and indirect income and various jobs in developing nations. This study investigated the impact of homestead pond fish farming on dietary diversity (HDDS and MDD-W), food security (HFIAS and ELCSA), income, and women's engagement. A total of 185 households were selected randomly for data collection through well-structured questionnaire interviews in the central coast of Bangladesh. HDDS revealed significant dietary diversity (73.3%) among beneficiary farmers, surpassing controls and nearly doubling that of non-aquaculture farmers (41.1%). Additionally, this study found that 86.7% and 74.3% of women in beneficiary and homestead pond farmers exhibited high dietary diversity (MDD-W ≥ 5), whereas 48.6% of women in non-aquaculture farmers' households had low dietary diversity (MDD-W ≥ 5). Based on both ELCSA and HFIAS, higher prevalence of food security was observed among the beneficiary farmers that was about 60% and 63.3%, respectively compared with the control farmers. Most non-aquaculture farmers (62.9%) indicated their family consumed fish for one week before the research. More than half of the homestead pond culture (55.7%) and more than 90% of the beneficiary farmers, aquaculture farmers and non-aquaculture farmers had gross income (
