AMADO. A fungus that looks and feels like a piece of soft leather. It is used like a sponge to dry flies.

AMPHIDROMOUS: life cycle which involves spawning in fresh water, but young fish are swept downstream and out to sea where they remain for a few months, before returning to coastal streams.

ANADROMOUS: life cycle that involves a migration from the sea into freshwater for spawning.

ANTENNA. Pair of joined sensory organs or feelers on the head.

ANTRON. Synthetic fibre of nylon with triangular cross section which refracts light giving it a sparkling appearance. Ideal as a dubbing material.

ATTRACTOR. Two meanings to the fly fisherman. 1. A fly that has a flashy appearance and its main purpose is to attract the fishes attention.

BACK WATERS. (aka "Anna Branch) A term used to describe sections of rivers, lakes or impoundment's that are not part of the main watercourse.

BACKING LINE. Fly lines are typically only 27-30 meters in length. Backing line is additional line attached behind the fly line to increase its length. It may be required in order to let bigger fish run or to fill out the reel so that the fly line is stored in as big a loops possible on the spool. You can use monofilament as backing line but if wound onto a spool tightly it may split the spool. Braided nylon or Dacron are better options.
