The torpedo shaped flowmeter allows us to keep track of the volume of water that filters through our plankton net.

Launching the neuston plankton net.

Our most effective tool for catching bluefin tuna is the neuston. Typically the neuston is towed at the surface. However we adopted a technique, from our Spanish colleagues, where the towing cable is continually adjusted through out the tow. This makes the net undulate through the first 10m of the water column, and is much more effective at catching larval bluefin.
