more algae

Post by JohnLucas1316 » Wed May 15, 2019 3:18 pm

According to The Guardian newspaper, the Norfolk Wildlife Trust are to spend £500,000 on a "bio-manipulation " project to try to clean the water on Ranworth and Barton Broads.
The plan is to remove some of the roach and bream in hope that zooplankton will proliferate and eat the algae that is making the water murky.
Because the water is murky, light cannot reach the bottom of the lakes and aquatic plants die off. If the project works and aquatic plants return, it is hoped that, "predators such as pike will reduce the impact of the zooplankton- feeding fish by moving them around more".
Of course, as usual it's all about the birds, and the Wildlife Trust are hoping that osprey and common terns will return to the area.

Over in Leicestershire, apparently the River Soar is becoming too clear in places because of the filtering action of millions of asian clams, an alien invasive species that is rapidly spreading in the UK.
It's a funny old World.

The Barton broad part of the project will be in areas already cordoned off.The Ranworth broad part of the project will be newly created areas,Ranworth is not open for public fishing.I am awaiting more information on all of this,I'm not happy how they are presenting this to the public as it has not been fully signed off by the EA.The Lear water status seems more important than fish to most of these groups ,a bit worrying.

It's all about the birds. Fish are just bird food for these groups.

Sadly some of it isn't, a lot of support from people who just want to see clear water and sod the consequences.
