In summer, throw a buzzbait or other top-water moving bait into mosquito fern (Azolla sp.) and wait for those big bass blow-ups!
Spring—Plants are present in the spring as tiny spores but not yet visible to the naked eye. Fishing benefit is negligible during this time.
Summer—Plants will rapidly break up at branching points and form numerous new plants. The result is colonies of mosquito fern that will begin to become visible to the naked eye. Colonies will become apparent in late summer and offer up some great topwater fishing. Throw a buzzbait or other top-water moving bait and wait for those big bass blow-ups!
Fall—By early fall, mosquito fern colonies will span entire coves and quiet backwater areas. Colonies will be much thicker by mid-fall. Throw weedless topwater baits capable of maneuvering across large colonies. Fish can easily break through mosquito fern to take down prey.
Winter—Plants will rapidly die with reproductive parts sinking to the bottom. These reproductive portions will again rise in the spring to create new plants. Fishing benefit is negligible during this time.
Fish—Provides habitat for many species consumed by insectivorous fishes.
Waterfowl—No known food value for waterfowl.
What it Looks Like—A tiny water fern, native mosquito fern is easily identifiable by its Christmas-tree shape. In fall, large colonies of mosquito fern will turn dark red creating a crimson look to large areas.
Where to Find It—Mosquito fern prefers calm water areas in the backs of creeks and embayments. Is often mixed with duckweed species.
Similar Species—Similar in size to duckweeds but is easily distinguishable by shape and color.
Mosquito fern can inhibit some water uses and management is often needed when colonies grow to nuisance levels. Cost to manage: $$$ out of $$$$$.
