Fishing Line and “No-Take” Zones Studied to Combat Coral Disease

Coral CoE is at it again trying to understand how human impact can effect change on coral reefs around the globe. Studying marine reserves in and around the Great Barrier Reef scientists “surveyed more than 80,000 corals around the Whitsunday Islands for six different diseases that commonly harm reef corals around the world.” -Lead researcher, Dr Joleah Lamb from Coral CoE. What they found was that areas protected from human activity (no-take marine reserves) had a much lower amounts of indigenous disease, and that coral actually have increased rates of health.150602130652_1_900x600“We found three coral diseases were more prevalent on reefs outside no-take marine reserves, particularly on reefs with high levels of injured corals and discarded fishing line. Fishing line not only causes coral tissue injuries and skeleton damage, but also provides an additional surface for potential pathogens to colonize, increasing their capacity to infect wounds caused by entangled fishing line,” added Dr Lamb. “No take marine reserves are a promising approach for mitigating coral disease in locations where the concentration or intensity of fishing effort is relatively high,” says Professor Garry Russ from the Coral CoE.

Anti-HIV Protein Found in Cnidarians

A recent chance discovery by scientists that were thumbing through the National Cancer Institute’s extract repository, has produced a possible anti-HIV protein from the coral phylum Cnidaria. The proteins discovered were then purified and tested on HIV cells and scientists found that these proteins attached themselves to HIV cells inhibiting the transfer into the human bodies T-cells (the most targeted cell by HIV). Senior investigator of this study Barry O’Keefe adds: “The natural products extract repository is a national treasure, you never know what you might find. Hopefully, discoveries like this will encourage more investigators to use this resource to identify extracts with activity against infectious disease.” Read more here!ElecMicro_of_HIV_Retrovirus_serum_isolate_Samp-HM47More:

Interzoo 2012: The Prodibio booth

Walking inside the Stand 4, we visited the small stand Prodibio that  seemed extremely interesting. I presume that you all know the Prodibio as one of the most important companies in the production of bacteria for aquarium, and that therefore many of you have used the mythical glass vials.

  During the show Prodibio presented a new protocol for the treatment of diseases in aquariumMore:
