Field Experiments on the Attraction of Pelagic Fish to Floating Objects

Floating objects were evaluated as fish attractants in the offshore waters of Costa Rica. Flat plastic sheets were suspended vertically in the water and floated horizontally at the water surface. Sheets that floated on the water surface attracted more fish than those suspended vertically if they had equal surface area submerged. If the outside dimensions of the objects were equal no differences existed. The most fish were attracted to a plastic sheet bent at a 60 angle at its midline so that it resembled a small tent which floated with both sides submerged.
