    Me and my old man were fishing in Eden NSW off the Navy Warf and he pulled in what looked like a shark, it had come of in the air. The bait which was a pilchard had some sort of blue flurescent liquid on it which later dimmed. Can anyone help identify this?
    Thanks

    G'day Adam,

    Firstly, welcome to the forum.

    The fluorescence or what is known as bioluminescence is caused by single cell critters called plant plankton. It usually occurs when the water has warmed, is quite common around the coast at this time of year and generally requires some sort of water agitation to trigger the luminescent glow such as wave movement or an object moving fast through the water.

    There have been instances in recent years where large areas of close inshore water has been turned electric blue by this brilliant display of nature. The 2 pics below were taken at Manly beach a few years ago - ref:SMH.

    Hope this answers your question.

    With the increase in global sea temperatures, you will most likely encounter it more often, Adam.

    The sea temperature today in Eden is 21.1 degrees C which is almost 2 degrees higher than the January average of 19.4 degrees. A rise of 1.7 degrees may not seem much to us land animals, but to the marine environment, it is a lot.
