  abstract = {{T}he predominant policy for remedying the world fishing crisis aims at maximum sustainable yield ({MSY}) by adjusting gear selectivity and fishing effort to maintain sustainable stock levels. {T}he yellowfin tuna ({T}hunnus albacares) fishery in the {S}ea of {O}man has experienced intense increases in removals since 1980, with particularly high levels since the 1990s. {H}ere, we apply a statistical catch-at-age model to time-series of catches and fishery-dependent length composition data to obtain a preliminary and general understanding of the population dynamics of this stock since the start of the fishery in 1950-2019. {D}espite limited data, population models consistently indicate a sharp decline in population status since the beginning of the time-series across a variety of assumptions on stock productivity and life history. {T}he gillnet fishery takes almost exclusively immature individuals, with high fishing intensity and removal rates. {B}oth reference models indicate the population is essentially at the same relative stock status in 2019 (10/100 of unfished), but with very different future projections and higher absolute stock size when recruitment is estimated. {T}he yellowfin tuna population in 2019 is below estimated {MSY} reference points (based either on unfished size or spawning output at {MSY}) for current relative stock size, and over the fishing intensity at {MSY}, indicating current overfishing. {A}djusting the interactions of that fishery with the population, while continuing to collected biological composition data representative of each fleet in the fishery, will help mitigate current stock decline and provide the ability to refine future population status determination and forecasts through more informed stock assessments.},
