Selfish do not survive in captivity. These large, fast and mostly solitary fish live in the open ocean, making them difficult to study. His vision of fish prey has gained scientists now have an idea of how much food a sailfish needs per day. Sailfish are often called the fastest fish in the world According to the Australian Museum, the fish have been known to swim at speeds in excess of 68 miles per hour. Less is known about how they meet their nutritional needs while living alone.
NSU Guy Harvey Research Institute doctoral student Ryan Logan is the lead author of a paper on sailfish hunting behavior that appeared late last month in the journal Scientific Reports. Discussed search results and shared footage.
If you're expecting a heart-pounding action-adventure movie sequence, you won't get it here. The clips feature lots of blue water and close-ups of fish bodies. A predatory fish is seen when a sailfish is in hot pursuit (45-kg) The sailfish makes a rapid ascent to the surface and then performs acrobatic maneuvers in an attempt to catch a small tuna Insights into sailfish hunting behavior There was an unexpected bonus.
To try to answer this question, the research team created a special electronic tag package with sensors and a camera to measure how long it takes for sailfish to recover after being caught and released. The latter closes, but it was enough to capture the thrill of hunting and send researchers in a new direction of study.
Based on data collected from the tag along with video footage, the researchers estimated that the sailfish needed about half as much tuna each day as they were hunting to meet their energy needs.
"Sailfish are a popular target for sport fishing," said NSU study co-author Mehmood Shivji. It is essential to help us better protect the health of these fish and their prey in order to have a sustainable sportfish industry for many years to come.The Secret Life of Sailfish looks like it would make a great documentary.
