Resumen

Este estudio investiga las variaciones estacionales en el contenido total de lípidos y la composición de ácidos grasos de cinco especies de peces (Capoeta trutta, Capoeta umbla, Carasobarbus luteus, Carassius gibelio y Cyprinus carpio) del embalse Dicle, Diyarbakır, en el sistema fluvial mesopotámico. C. gibelio mostró los valores totales de lípidos más altos, con porcentajes de 7,57 % en invierno, 8,55 % en verano y 8,30 % en otoño. En C. trutta, SSFA alcanzó su máximo en otoño (38,64 %), principalmente debido a C16:0 (27,08 %), y SPUFA fue más alto en invierno (38,31 %), con los principales contribuyentes siendo EPA (12,21 %) y C18:2ω6 (10,85 %). C. umbla tuvo su SSFA máxima en otoño (31,27 %) y SPUFA en invierno (43,06 %), impulsado por C18:2ω6 (19,14 %) y EPA (9,27 %). Tanto C. trutta como C. umbla presentaron su máximo de SMUFA en verano, principalmente por C18:1ω9. C. luteus mostró altos valores de SPUFA en otoño (48,88 %) y verano (48,30 %), con DHA C22:6ω3 alcanzando 16,69 % en verano. C. gibelio alcanzó su SPUFA máximo en invierno (49,89 %) y verano (49,33 %). C. umbla presentó la relación Sω3/Sω6 más alta en primavera (2,04). Las variaciones estacionales en la composición de ácidos grasos reflejan los perfiles lipídicos dinámicos de estos peces de importancia comercial, proporcionando información sobre su calidad nutricional y orientando recomendaciones dietéticas estacionales.
