Development of the silver eel (Anguilla marmorata) gonad during downstream migration in the Lake Poso system, Central Sulawesi

The Lake Poso system is located in Central Sulawesi and is connected to the Tomini Bay by the Poso River. It is known that five out of nine Indonesian eel species were found at the Poso River. Anguilla marmorata is the most caught species. However, uncontrolled catching during downstream migration a...
