Umur glas eel (Anguilla spp.) yang masuk muara Sungai Progo Yogyakarta
The leptocephalus drift with sea currents and moving from spawning area into coastal area near mouth of Progo River. In thecoastal area, leptocephalus metamorfosed into glass eel, after that glass eel migrated to river. The aims of this research were to estimate glass eels age and predict hatching d...
