Dear all, i'm an italian researcher. I have tryed to find information about pingers, used as acoustical device to avoid cetaceans by-catch. I'm interested particularly on outcomes related on tursiops in open water. I have found some interesting results searching on internet:
Stone, G. S., Cavagnaro, L., Hutt, A., Kraus, S., Baldwin, K., Brown, J. "Reactions of Hector's dolphins to acoustic gillnet pingers" 2000 Jefferson, T. A., Curry, B. "Acoustic methods of reducing or eliminating marine mammal-fishery interactions: do they work?" 1995 My problem is that all the works related with tursiops demonstrate that after a short period, mainly 3 months, dolphins get used to the sound , so this acoustical device works for a very short period. After that they are actracted by the sound because it remainds them a possible source of food. As i would like to continue the sperimentation for a project on dolphins located in the Pontine islands in Italy, i would like to take a look at as much results as it possible. If anyone could help me, please feel free to contact me. Thank you everyone.
