We usually suffer from blue-green algae in the heat of summer, but it's autumn now and quite cool. Must be a lot of nutrients in the lagoon.
Gold Algae Eater
Gyrinocheilos aymonieri
This slender algae eater has a silver underbelly with a bright yellow/gold back. A horizontal line that is patterned runs along the side. The Gold Algae Eater comes from Northern India. It is usually kept in tanks for the purpose of keeping algae under control.
The main source of food is algae on plants, rocks, glass, and driftwood. Algae based wafers should be provided if there is a lack of algae.

San Diego has the largest algae R&D cluster in the world. As part of the 2010 Algae Tour, I was able to get the inside scoop on the progress many of the companies are making in bringing algae fuel and products to market.
Because of their calcified structure, coralline algae have a number of economic uses. The collection of unattached corallines (maërl) for use as soil conditioners dates to the 18th century. This is particularly significant in Britain and France, where more than 300,000 tonnes of Phymatolithon calcareum (Pallas) Adey & McKinnin and Lithothamnion corallioides are dredged annually. Some harvesting of maërl beds that span several thousand kilometres off the coast of Brazil takes place. These beds contain as-yet undetermined species belonging to the genera Lithothamnion and Lithophyllum. Maërl is also used as a food additive for cattle and pigs, as well as in the filtration of acidic drinking water.
The earliest use of corallines in medicine involved the preparation of a vermifuge from ground geniculate corallines of the genera Corallina and Jania. This use stopped towards the end of the 18th century. Medical science now uses corallines in the preparation of dental bone implants. The cell fusions provide the matrix for the regeneration of bone tissue.
Since coralline algae contain calcium carbonate, they fossilize fairly well. They are particularly significant as stratigraphic markers in petroleum geology. Coralline rock also functions as building stones, with the best examples being in Vienna, Austria.
The clarity on this is better and the color more apparent on this snail. You can see the cross fibers of the algae growing on the window of the tank (and here I thought i just cleaned it...if you can see this imagine what you kitchen table would look like under a microscope...)
This guy is about .5 centimeters in real life
this single swan was in a small rivulet completely covered in green algae, as you can see from its beak
There was a very small freshwater creek entering the ocean at this point.
The entire course of the creek's journey over the rocks to the sea was carpeted in this interesting algae.

Researchers at Bowling Green State University worked with NexSens Technology to deploy a new monitoring buoy in Sandusky Bay. Algal blooms in Lake Erie are a persistent problem, with the main concern being clean drinking water. This buoy is equipped with sensors to measure algae and provide advanced warning to managers at the Sandusky Big Island Water Works Intake. Here, Doug from NexSens shows researchers how to view live data from the WQData LIVE web datacenter.

Levi Lewis, graduate student at Scripps Institution of Oceanography at UC San Diego, measures the density, diversity and height of algae in one of 40 experimental plots, which he has established across 500 meters of natural reef in the Kaanapali region of West Maui, Hawaii.
As part of his dissertation research, Lewis is testing the relative importance of different species (and combinations of species) of herbivorous sea urchins on a natural reef in Maui, Hawaii.
“Coral reefs persist where a balance is maintained between coral and algal growth. The ultimate goal of this particular project is to assess the similarities and differences in the effects of each species of urchin, as well as the consequences of species combinations, on the algal and coral communities,” said Lewis. “The results of such a quantification will tell whether mono-specific, or multi-specific communities of herbivorous urchins might result in the most effective control of algae, and facilitation of coral growth.”
According to Lewis, there is a rapid loss of coral reefs and around the world. It is important that we understand the factors that improve coral reef resistance to algal phase shifts.
Lewis has recently been awarded funding from the Mia Tegner Fellowship for his proposal entitled “Biophysical Determinants of Coral Reef Development and Growth”. Photo: Don McLeish
