Algal Bloom

The research by scientists at the Woods Hole Oceanographic Institution is based on how much of the toxic red tide algae they found in its dormant state in the Gulf of Maine last fall. The dormant cysts act like seeds for the next years bloom.

The researchers then combine the cyst data with computer simulations of various conditions that affect the algaes growth Starbrite Tattoo Ink, such as winds and currents.

The prediction helps the shellfish industry and environmental managers better prepare for the annual bloom.

In a bulletin, BFAR also said shellfish harvested from Dumanquillas Bay in Zamboanga del Sur, Murcielagos Bay in Zamboanga del Norte and Misamis Occidental, and the Bataan coastal waters are still positive for paralytic shellfish poison beyond the regulatory limit.

The popular trout-fishing lake, which was closed May 3 only days after it was opened for the fishing season April 28 remains closed to recreational use while the 410-acre state park around it stays open.

The level of anatoxin-a, a potent and quick-acting nerve poison, was measured at 70.0 micrograms per liter in Anderson Lake last week.

The safety threshold for the toxin is 1 microgram per liter.

The week before, the level was 1.52, so the new results of tests on samples taken last Monday which were announced late last week showed an increase of 46.6 times.

Test results have revealed a toxic algal bloom has extended over an unusually large area south of Hobart.

Tasmanians are advised not to eat wild shellfish from the Huon Estuary, including Port Cygnet, down the west coast of the D'Entrecasteux Channel, through Port Esperance to Southport and Hastings Bay.

Commercial shellfish farms in the affected areas have been closed.

NORWAY - Toxic algae blooms are suspected in Nordland following the report of 550 tons of dead famed salmon over the last ten days.

The fish deaths were first detected in a plant in Srfold.

Last weekend, dead fish were also noted in a facility in Tysfjord.

Fisheries authorities are urging farmers in the area to keep a watchful eye on the situation, in case of the spread of any harmful algal growth.

A red tide measuring more than 100 square kilometers drifting toward east China's coastline is threatening local fish and aquaculture industries, as it can suffocate marine life, local authorities said.

The Bureau of Fisheries and Aquatic Resources (BFAR) yesterday reiterated its warning that shellfish in the affected areas should not be harvested and eaten as they could cause paralytic shellfish poisoning.

This ban remains in effect in the towns of Mariveles, Limay, Orion, Pilar, Abucay, Samal and Orani and Balanga City in Bataan, and Masinloc Bay in Zambales, said BFAR regional information of

A blue-green algae outbreak last year prompted a warning not to eat lakes fish unless they were gutted and gilled.

But that advice has been lifted because of a drop in algae levels.

A warning against eating prawns, mussels and crabs caught in the lakes remains in place.

Dale Sumner from the Lakes Entrance Fishermen's Co-operative says fishers have had to gut and gill their catches before they can be sold.

He says the lifting of restrictions is great news for the local industry.

"It will be a relief to the fishermen working on the lakes," Mr Sumner said.

"It will also ha

I believe my tank is suffering from an outbreak of this lovely stuff, I have always had small patches of what I thought was red slime algae which I just siphoned out weekly. It was never really a problem until the past week when my Seachem Seagel passed its expiry date. Suddenly the algae spread like mad and is a dirty brown with tons of bubbles in it, it is even covering the glass at a rather ridiculous rate. I have replaced the Seagel and have tried siphoning and water changes with no luck at all, the stuff is just back within hours of the lights coming back on.

So I'm thinking of emba
