Oleoresin capsicum OC is an oily extract of pepper plants of the genus Capsicum. Each year, millions of pounds of capsicum are imported into the United States, primarily from India, Japan, Africa and Mexico. It is used as a spice in salsa, chili, curries, and hot sauces; as a pharmacologic agent in topical anesthetic and analgesic creams; and as the principal active ingredient in OC spray, or "pepper spray," used by police and others as an antipersonnel agent. Capsaicinoid content determines the "hotness" of the extract.
By Dinah Voyles Pulver dinah. The animals were emaciated, as if they had starved to death, said officials with the Florida Fish and Wildlife Conservation Commission.
Like many of the other deaths among the marine mammals and shellfish, scientists aren't sure what killed the pelicans.
Tests for diseases that can commonly cause deaths among birds were all negative, said commission spokesman Kevin Baxter. Although Blink response journal species has recovered from its historic lows in the s and s, some bird scientists remain concerned about pelican populations in Florida, chiefly because they've noted fewer pelican nests over the past decade or so.
Besides the recent mystery deaths, Audubon also is concerned because of the entanglement issues they're seeing among the birds, Wraithmell said.
One bird will pick up a piece of Blink response journal monofilament line and take it back to the colony, she said, where other birds can get tangled up in it and die. At Goodrich Seafood Restaurant on Mosquito Lagoon in Oak Hill — on the north end of the lagoon system — Neal Goodrich sat on the deck one afternoon and noticed that in more than an hour, he didn't see a single brown pelican.
Wearing waders and gloves, he hauls the traps out of the water, hoping for a bountiful harvest of blue crabs, just as he has done for four decades.
Bucurel quit school when he was 15 to fish. Like his grandfather before him, he said that's all he "ever wanted to do. Bucurel has seen a decline in health of the lagoon, citing murky waters and dead sea grasses.
Algae blooms and other troubles plague the lagoon system. Bucurel and others say populations of crabs and clams have plummeted, unable to survive the thick soupy algae blooms. He estimates his crab harvest last winter was only a quarter of what it was two years before.
Experts have seen it elsewhere. Chris Gobler, a brown tide expert with Stony Brook University, said a brown tide similar to the algae now in the lagoon system once killed more than 99 percent of the hard clams and scallops in a New York estuary.
They do track harvests and trips fishermen take to harvest shellfish. They're hearing anecdotal stories about the shellfish from fishermen like Bucurel and Tom McCrudden, a Tequesta aquaculture researcher who sells clam "seeds" to aquaculture farmers trying to grow clams. Seeds are baby clams. High algae levels are wreaking havoc on oysters and clams in the northern part of the lagoon system, said McCrudden.
On the southern end of the system in Martin County, he said, water releases from the Lake Okeechobee area, laden with nutrients, wiped out shellfish this year. The algae probably limits the ability of the shellfish to feed, Geiger said. He tried planting seeds this year, he said, and they "looked like they were going to start pretty good, but as soon as that brown tide starting coming in, they croaked.
While the Lake Okeechobee releases destroyed some of the oyster reefs in the southern end of the lagoon, oyster beds in Mosquito Lagoon on the north end of the lagoon system fared better, said Linda Walters, a University of Central Florida professor and researcher.
Walters said the beds she monitors — restored through collaborative projects with the UCF, Nature Conservancy and others — seem to be surviving.
She monitored oyster reefs in Mosquito Lagoon at Canaveral National Seashore over the summer and saw "no obvious die-offs" and also new recruitment in oyster settlements.
Each oyster is capable of filtering up to a bathtub's worth of water — 50 gallons — every day. Besides providing food for other species in the lagoon, experts say shellfish filter the water and act as a pH buffer to sediments on the bottom.
The reefs provide food for other species and help stabilize sediments and control erosion. Scientists also have found that sea grasses will take root and grow near the new oyster reefs.
Buoyed by that local success and already active in oyster restoration projects, Brevard County plans to step up its oyster gardening activity, Brown said.
It's one facet of his three-step, three-R plan for restoration, "restoring the filter feeders. Bucurel is skeptical of plans to improve water quality by planting oysters, when so many shellfish are dying, but he's hopeful someone will come up with some answers to help.
The hazard signs did not. The signs — posted for months this past summer and fall — warned would-be swimmers and fishermen that the blue-green algae in the water was toxic to human health, a situation that infuriated and frightened thousands of residents.
No such signs were required in Volusia and Brevard counties, but the algae blooms that have clouded the water in the Banana River, Indian River and Mosquito Lagoon for three years -- all of which are part of the Indian River Lagoon system -- have been no less annoying to residents or harmful to the economy.
Experts and residents alike wonder whether the massive algae blooms are part of a new normal. On the south end of the lagoon system, experts knew right away what triggered the toxic algae blooms: Lucie River from Lake Okeechobee, and a large drainage basin between the lake and urban areas to the east.PubMed comprises more than 28 million citations for biomedical literature from MEDLINE, life science journals, and online books.
