An eel called Ellie

Thank you to Gavin Gatenby for putting together this impressive movie about 'Ellie' the Longfinned Eel (Anguilla reinhardtii).  As he says in the commentary, the freshwater eels are known for their impressive spawning migrations. Four species of Anguilla are known from Australian waters.

One small step

Friday the 11th of February 2011 was a big day for me but the environment is the big winner. This was the official ceremony to announce that St Mary’s Star of the Sea College was banning the single use plastic bottle.

This week in Fish: Shark in trouble

It was a 'week of sharks'.  The highlight was the addition of some quite disturbing images of a White Shark being 'strangled' by a plastic packing strap.  Other less upsetting images, including two of Galapagos Sharks, were also added to the site.  Thank you as always to all of you who contributed and commented throughout the week.

This week in Fish: Southern Smiler

This week considerable effort has gone into the 'master list' of species on the site.  When completed, the list will allow users to easily see a summary of the images and fact sheets available for each species.  As usual, some great images were added during the week, plus a fact sheet on shrimpgobies and their relationship with burrowing shrimps.  Thank you to all our contributors.

Solar power switched on

The Station's new solar power system was switched on at 3.00 pm on Thursday 24th February 2011. It was designed to reduce by about 50% the amount of diesel used for generating electricity and hence reduce carbon emissions by that proportion. In its first month of operation, it has been working much better than that.
