Catch Composition and Bycatch Species of Fyke Net from Glass Eel Fishery in Aparri, Cagayan, Philippines

Abstract
The Cagayan River estuary in Aparri, Cagayan, Philippines, is a traditional site for glass eel collection. Local fishers use fyke nets as the primary fishing gear, with fine mesh nets and motorized fishing boats. Although the target species is the glass eel, the fyke nets also captured untargeted species, or bycatch, which play significant roles in the estuarine ecosystem. This study aimed to assess and identify the species of glass eels and the species composition of bycatch from this type of fishery. A total of 31 bycatch species, belonging to 16 families, were recorded, many of which are economically important, such as Carangidae, Clupeidae, Engraulidae, Gobiidae, Mullidae, Penaeidae, Sciaenidae, and Serranidae. Two species of glass eel were identified based on caudal cutaneous pigmentation, namely, Anguilla bicolor pacifica and Anguilla marmorata. This type of fishery poses a threat to bycatch species, as most are caught before reaching maturity; however, it has not received adequate attention. The main implication of this study is the need for proper recording and monitoring of these juvenile bycatch species to ensure the sustainability of the resources.
