Novel Procedure For Implanting Bio-Loggers In Atlantic Bluefin Tuna
Measuring heart rate using bio-loggers in free swimming fishes to detect their response to environmental impacts is a promising tool in aquaculture. It is of great value to have an insight into what drives migration in fish and the impact this could have on commercial utilization and conservation. Due to the logistic challenges that are involved, especially in the study of physiology of large pelagic fish, it has been vital to design simple, less stressful procedures. To perform an invasive surgery into the body cavity to place a bio-logger close to the heart is a difficult option on a commercial vessel with the risk of harming these large fish.
