KABC: Fish suffocate, die in Redondo Beach marina





Millions of fish were found dead in a Redondo Beach marina early Tuesday morning. Authorities say tests show the fish suffocated.
Boaters woke up to find the small, silvery fish floating around their vessels at King Harbor Marina.
"We believe the sardines were chased in, probably by some other type of predator fish," said Sgt. Phil Keenan of the Redondo Beach Police Department.
Authorities also tested the water for oil and other contaminants.
"There are no signs of oils or chemicals or anything else in the water that shouldn't be," said Andrew Hughan of the state Department of Fish and Game.
Millions were seen dead in the harbor, but millions were still alive and being fed on by sea lions and birds.
"The water content is good," Keenan said. "There are other fish still living. It's just the sardines that died off."
Officials initially said a red tide may have been the cause of the oxygen deprivation, but Keenan said that was not the issue. Red tide is a naturally occurring bloom of toxic algae that can poison fish or starve them of oxygen, according to Staci Gabrielli, a marine coordinator for King Harbor Marina.
"What we're operating under is that there were so many sardines, and sardines consume a lot of oxygen, and there was not enough oxygen in the confined area that they were, so they died of oxygen deprivation," Keenan said. "It's like putting too many fish in a small aquarium."
It was reported that there were millions of dead fish so thick in the marina that in some places, many of the 1,400 boats could not get out of the harbor.
"I've lived in Hermosa Beach since 1963 and I've never seen anything like this," said Bill Lyle, who was surprised to see the massive amounts of belly-up fish.
Crews say they will take the dead fish to a landfill. They had thought about putting the dead fish out in the sea, but officials said it would be impossible to accomplish.
The clean up was expected to take days.

Freshwater Planted Tank of Marcel A. Wuethrich PhD



Recently I was able to get to know Dr. Marcel Wuethrich through some email correspondence. He has a 180 gallon system and I was finally able to get see some pictures of it and I was blown away. The system is illuminated with four Aquatic Life 36 inch dual lamps all linked together. As a result of the lighting the plants are in fact growing nicely. The substrate is 10 parts top soil (non-fertilized), 2 parts red flint gravel, 1 part calcined clay ( to bind the minerals so they do not leak into the water columns) and 1 part peat moss. He uses the peat moss to lower his pH as the tap water has a pH of 8 and adding the peat moss to the substrate brings it to pH 7. After placing 1-2 inches of this formula it has been topped off with 2 inches of red flint gravel.
Marcel also breeds Rainbow fish. He reports that his Melanotaenia sp. Aru II are coloring up fantastically in his 180 gallon glass box.
It is tanks like this that continue to inspire us all and push us to create our own wet worlds.

World’s smallest tank


Recently our own Luis Tapatio (like the hot sauce) voiced his desire for a simple freshwater tank. After seeing this video we thought it would be just perfect for him!
Measuring in at 30x24x14mm we can only hope that the tanks inhabitants were moved to a more suitable sized tank after the video was shot. The tank makes great use of substrate and even some algae molded into the shape of plants to help fill it out.
Recently we at Aquatic Life released our new 20 inch tiny fixtures but I think we may need an even smaller fixture for this bad boy. I can only wonder what kind of power head could be shoved in there for some monster flow!
