Aquarium fish farming is among the most disaster-sensitive aquaculture activities due to reliance on water quality, oxygenation, and fragile infrastructure. Earthquakes can cause structural damage, water contamination, and power outages, leading to high stock losses and reduced resilience of small-scale enterprises. This study examines the impacts of the February 6, 2023 Kahramanmaraş earthquakes on ornamental fish enterprises in Hatay province, Türkiye. A survey of 54 businesses revealed that 57% remained active while 43% ceased operations, with retail enterprises disproportionately affected. Among active businesses, 87.1% operated in retail sales and 12.9% in wholesale and breeding, whereas 95.7% of closed enterprises were retail-based. Results showed severe biological and infrastructural losses. Sixteen enterprises reported complete fish mortality, while others experienced partial losses ranging from 1% to 90%. Electrical systems were heavily impacted, with 11 enterprises reporting major damage and 3 unusable. Water systems suffered irreparable damage in 13% of enterprises, severe damage in 29%, and moderate or minor damage in nearly half. Ventilation and filtration systems were similarly affected, with 39.3% reporting severe damage. Structural damage ranged from minor wall cracks to total collapse, while closure durations varied from three days to over six months. Income losses were substantial: nearly half of enterprises reported complete cessation of revenue, while others experienced reductions of 25–75%. Recovery efforts highlighted significant challenges, including financial constraints, supply shortages, customer loss, and difficultyprocuring technical equipment and skilled staff. Thirteen enterprises reopened without external assistance, while others relied on multiple support sources. Post-earthquake supply continuity was severely disrupted, with only 3% maintaining normal operations. Preventive measures emphasized insurance, generators, and earthquake-resistant aquariums, while support requests focused on tax exemptions, financial aid, and low-interest loans. Overall, the findings underscore the vulnerability of ornamental fish enterprises to seismic events and highlight the urgent need for resilience strategies, including infrastructure reinforcement, financial safeguards, and comprehensive emergency preparedness planning.
