An English ⇄ Chinese glossary for the rest of fly fishing: the tackle, the tying bench, the insects, the water and the handling of the fish. The 96 FFI casting terms have their own collection — FFI casting definitions — and are not repeated here.

Terms are grouped by subject and alphabetical inside each group. Where Chinese anglers use the English word — CDC, WF, DT, PMD — the English is kept.
