[Coral-List] Worthing, Barbados

I'm not sure of the purpose of this post-but then, I wasn't sure of the purpose of the original one.

Boring sponges are a lot harder to locate and identify. It takes time to get your eye in-I would be glad to give you some pointers off-list, if you like. You seem to be aware of the importance of C delitrix, so I assume counts of its abundance are in your census papers.

I wanted to take the opportunity to inform -listers of the amount of good work that came out of the Bellairs Lab before the McGill Admin chased a different shiny object. There is a ton of grey literature stuff (search for Bellairs Lab Publications)-it's all pretty old, but data never die.

Not sure we're watching the same video, Mike,

I count less than 25 small patches of C. delitrix in the whole video, with several of those clumped on the same rock.
Again, much lower abundance, in my experience, than many Caribbean reefs.

Yes, thanks for that.

I note your video contains almost as many colonies of the fecal bioindicator Cliona delitrix, a boring sponge, as of giant barrel sponges.

Those interested in what science has to say about those reefs are encouraged to read the seminal work out of McGill, especially Tom Tomascik's stuff, and the 2002 paper by John Lewis that documents coral loss.

Coastal Zone also runs regular monitoring.

The SW coast of Barbados has better coral cover and lower seaweed cover than many reefs elsewhere in the Caribbean.  Here's a video tour from January 2019:

Notice the huge biomass of giant barrel sponges!!!!

According to Dr. Risk.Barbados is "...an island which could be characterized as an outhouse built on a karst outcrop". That´s pretty uncharitable. I´m trying as a Barbadian not to be offended and as a scientist to stick to facts so I have to add that we have two sewage treatment plants, one primary servicing the south and slated to be upgraded to tertiary and the other secondary, servicing the Capital. An increasing number of householders are choosing septic tanks over the traditional suck wells and our nearshore water quality (which is monitored twice monthly) is not the sewer one would expect given that analogy.
