Hit the Microscopy Jackpot

I just figured out how to capture images, nearly picture perfect as they appear under the microscope lens. My camera (Canon PowerShot S3IS) has a setting for "Sports" shots. It captures shots split second while reducing blur. So, the incredible result appears below:Enlarge imageImage #1 magnified at 40xEnlarge imageImage #2 magnified at 40xEnlarge imageImage #3 magnified at 40xEnlarge imageImage #4...

Volvox

Several years ago (around 2003) I made my mind up that one day, I was going to photograph a volvox after learning about these fascinating little creatures. They're somewhere between the plant and animal kingdom. A volvox is a colony of sisters, but they use photosynthesis / chlorophyll like plants do.Made a goal, stuck to it, and made it happen.Today, after all this time, I captured my first volvox....

Omega 3 Fish Oil Reducing Heart Disease

Yesterday "Doc" Doug Holland told our Aquaculture class that especially coldwater fish is good for your health, to eat it at least twice a week.

Can fish farming save depleted cod?

February 07, 2007By Simon RabinovitchLONDON (Reuters) - Cod, a mainstay food from Britain to Brazil, all but disappeared from Canadian waters in the 1990s after years of overfishing, and scientists say a similar fate awaits the shoals of the North Sea.But fish farms are putting cod back in North Sea water, at least within enclosed sea pens, easing the strain on wild fisheries and, fish farmers say, protecting a species that would otherwise be fished into extinction.Off the Shetland Islands in northeast...

Aquaculture in South Africa - Farming Endangered Abalone

'Abalone farming has the highest economic value as compared to all other farmed products'Known in South Africa as "perlemoen", abalone is so endangered the government has drastically reduced the total allowable catch in the wild and attempted to encourage saltwater farming of the curlicue-shaped shellfish.Resembling a giant limpet and a distant relative of garden snails, it thrives only in oceans or special land-based farms that use seawater to cultivate the creatures.'The amount of illegal abalone...
