摘　　要：Anguillids areаvaluable fish commodity worldwide.Although Anguilla luzonensis have been abundantly found in the northern Philippines and collected for trade,no available records show that it recruited in the mid-part where Lagonoy Gulf,Bicol is situated.In this study,we investigated the occurrence of A.luzonensis in the tributaries along the Lagonoy Gulf,Philippines using molecular tools.Glass eel specimens were collected in 2018-2019 from the Comun river,Albay;the Lagonoy river,Camarines Sur;and the Bato river,Catanduanes.Anguilla luzonensis was first reported in Lagonoy Gulf using molecular analysis.A.luzonensis was the second most abundant species in the Comun and Lagonoy rivers(9.5 and 22.4%,respectively).Anguilla luzonensis collected from the Comun and Lagonoy rivers did not show a significant difference(FST=0.00825,p>0.05).An­guilla marmorata was the most dominant species in all tributaries(71.1-98.0%).In the Comun and Lagonoy rivers,A.bicolor pacifica was the third most abundant species(7.7 and 6.5%,respectively).In addition,Anguilla celebesensis was only found rarely in the Comun river(0.9%).This study provides important information for sustainable resource management and effective utilization of the eel species in these regions.
