It is clear that a variety of human factors, including habitat reduction and overfishing, contribute to the decline in the eel catch, but there is also the possibility that changes in the ocean atmospheric system are affecting eel ecosystems. Identification of eel spawning grounds requires an extensive ocean survey, and thorough monitoring of eel movement from habitat to spawning grounds is also necessary.
