Abstract
It is necessarily that behavior of fish is controlled for preventing fish from entering and fishing with other fishes. For example, there are mothods of the light, the air bubble, the electricity and the magnetic behavior. Mylopharyngodon piceus and Cyprinus carpio is not influenced by the transmitted lig ht, and the transmitted light changes the swimming behavior of juvenile Oncorhynchus keta. It is suggested that the behavior to the transmitted light is different for fish species. Though the influence for Opsariichthys platypus and Candidia temminckii with the transmitted light is verified, the influence for benthic fish is hardly verified. This study was made to verify the influence of contrasting and color of the transmitted light for the swimming characteristic of Anguilla japonica. It is found that the swimming characteristic of Anguilla japonica is not influenced by contrasting and color of the transmitted light.
