  abstract = {{M}anaging fishing effort remains a central challenge in achieving sustainability in many fisheries, particularly where high-value species attract intense competition. {I}n the {I}ndian {O}cean tropical tuna fishery, understanding how fishers respond to changing bio-economic conditions is essential for developing effective management. {T}his study evaluates the influence of effort-based management measures on the size and investment behaviour of the purse-seine fleet targeting skipjack ({K}atsuwonus pelamis) and yellowfin tuna ({T}hunnus albacares). {U}sing {R}andom {U}tility {M}odels ({RUM}s), we identify the key economic drivers of strategic decision-making, validate them through model evaluation, and integrate them with age-structured operating models ({OM}s). {T}he {RUM} achieves 93% predictive accuracy, offering a robust basis for exploring policy options that balance conservation and economic objectives. {S}cenario testing under different cost and price conditions illustrates how economic pressures shape entry and exit decisions within the fleet.},
