![]() ![]() These lines were then checked every three or four hours. Early in the morning, we baited lines with large bits of fish and set them in place. The first step was to tag a number of sharks so that we could follow their movements. To do this, we first needed to catch the sharks. However, during the winter months the sharks disappear – so we decided to do some of our own research there. Observations here have shown that there is a large population of tiger sharks present in the summer, during the turtle nesting season. We are particularly interested in some studies that had been done in the Raine Island area. This is because it tends to feed in areas such as harbours and river inlets, where there is a lot of human activity. However, it’s not uncommon to find garbage in its stomach.

First of all, some background information. Today, I’m going to talk about the research project I’ve been involved in on the tiger shark. The shark was 38_ and could be tracked Questions 39, 40ģ9. The purpose of the research was to understand the tiger sharks’Ĥ0. Observations showed that, in general, tiger sharksī usually avoid the surface of the water.Ĭ often spend long periods on the ocean floor. ![]() Larger sharks: an acoustic tag was fitted or a 37_ was attached The shark was measured and tagged, and tissue removed for research The hooked shark was brought to the 36_ and secured Pieces of 34_ were attached to lines as bait The 33_ (when turtles are nesting) Questions 34-38
