Resumen
Bigeye tuna, Thunnus obesus (Lowe, 1839), yellowfin tuna, Thunnus albacares (Bonnaterre, 1788), and albacore, Thunnus alalunga (Bonnaterre, 1788), are very important species for world fisheries. The weight-length relations (WLRs) of the three species were studied using commonly accepted methodology. Significant differences can be found from the fork length distributions and the WLRs of the above 3 tuna species and the relations of gilled-gutted and whole weight of bigeye and yellowfin tunas collected from the Atlantic, Indian, and Eastern Pacific Oceans. Significant differences of fork length distributions can be found for bigeye tuna, yellowfin tuna, and albacore from the three areas. The date collected will be useful for the fisheries management of the three species studied
