Claim:
1. A helical fish aggregation apparatus comprising: a linearly elongated, cylindrical supporting member having a plurality of pairs of opposing slat-receiving cut-outs in a wall of the supporting member, each of the cut-outs defining at least one channel; a plurality of linearly elongated slats extending perpendicularly to the cylindrical supporting member, wherein the slats comprise a central ridge in a first direction, with laterally extending flanges substantially normal to the central ridge and distal edges curved opposing the central ridge, whereby the curved distal edges bear loadingly against a wall of a respective cut-out to bias the central ridge in the channel of the cut-out, wherein the slats are positioned at an oblique angle relative to each other; and said supporting member, when engaged with said slats, forms a generally helix-like structure for providing an artificial habitat for fish.
