In an era of anthropogenically driven biodiversity decline, monitoring the quantity and diversity fish stocks with long-term time series has therefore become great importance. Despite becoming more common, this is not case globally, especially in Türkiye, where research using long term biomonitoring data to investigate changes freshwater communities still very limited. The Euphrates Tigris catchments are two recognized hotspots Mesopotamia. These watersheds stem from Türkiye flow into Persian Gulf, having always been significant importance humans. current study, we collected information on 153 assemblages Turkish parts catchment 100 museum collections. samples covered period 1941 2022 were investigated a mixture approaches, including analytical occurrence, spatial, space-for-time models. We found that recent increase sampling effort resulted increasing numbers species reported for both catchments, over time. however identified considerable difference spatial distribution known richness, by heterogeneous differences suitability high richness. identify substantial areas lacking investigations potential numerous yet being described, while already suffered losses overexploitation anthropogenic pressures. Our findings suggest effort-driven disparity between catchment, hindering future assessments management or conservation interventions. Without improved assessments, may be lost without notice, it, ecosystem services function, thereby degrading human well-being.
