"Numerous experiments have been done on bass concerning their vision and ability to identify different colors and thicknesses of fishing line.  In one research project, bass were trained to strike targets connected to different-colored fishing line.  There were a series of targets connected to colored fishing line, bass were trained to strike certain colored fishing line in order to receive a reward of food.  Once the bass learned which color line resulted in a reward, the experiment was repeated with fishing line of smaller diameter. Bass were able to quickly select the fishing line of the desired color down to four-pound-test line.  This experiment was repeated with different-colored fishing line.  Bass were also able to discriminate between different colors of the fishing line with a high degree of accuracy.  this experiment proved several things.  Bass have highly developed color vision and were able to determine the differences between clear, purple, green, blue, yellow and pink fishing lines. Bass apparently have a fine degree of visual acuity, being able to see very thing fishing lines without difficulty and from a long distance."   "What Fish See"   Colin J Kageyama   Rick
