Longtan is a small township in Taoyuan county situated just below Shihmen Reservoir. There are several ponds in the area, and though many are fenced off for commercial purposes, a few are accessible and fishable.
I'm not exactly sure which pond this was shot at, or whether the anglers had to pay to fish it, but it produced a few nice largemouth bass and at least one monster tilapia. Largemouth are not native to Taiwan, of course, but they are farmed here and a few escape and go wild in local ponds and lakes.
I went out to Longtan last weekend looking for the fabled bass pond, but came up empty handed. I plan to head out again this weekend and will report here on the action (if there is any action to report).
(UPDATE) I have since figured out that this Longtan (translation: Dragon Lake) is the lake located just north of Yilan city and is not related to Longtan township in Taoyuan County. I recently took my family here for a picnic, but only had a time for a few minutes of fishing. I look forward to heading back when I have a little time for fishing.
