MASS FISH DIE-OFF: DISASTER PRECURSORS

January 18, 2012 - UNITED STATES - Tens of thousands of dead fish washed ashore on a South Carolina beach on Tuesday, for at least the second time in a week. Approximately 30,000 to 40,000 menhaden fish washed ashore along a mile-and-a-half-long stretch of beach from Georgetown County, S.C., to Pawleys Island, said Pawleys Island Police Chief Michael Fanning, according to NBC News. It seemed likely that thousands more of the 6- to 8-inch-long fish would wash ashore later.

This is the second time in one week such an incident has occurred in the area, notes NBC News. Late last week, hundreds of thousands of the small, oily fish washed up near Masonboro Island, N.C. "One time I was here I saw a bunch of jellyfish," South Carolina resident Bill Vogel told NBC local affiliate WMBF Newsof the dead fish. "They were all on the shore but nothing like this, it's really weird."  The Department of Natural Resources (DNR) tried to explain the fish die-off on Wednesday. "It's an occurrence called hypoxia," Sergeant Steve Pop told WMBF. "That is dissolved oxygen levels in the water that drop to a level that is not sustainable for the fish... 

We've got some deep holes off of north inlet that holds these fish. This time of year the fish congregate in these holes which is depleting the oxygen source." Mel Bell, Director of the Office of Fisheries Management for S.C. DNR, elaborated on the theory: “On Friday we had a new moon [which caused] real high high tides and real low low tides,” he told The Sun News. “Probably what happened was a school [of menhaden] got in an area of water on a high tide, in a hole or depression, and at low tide they were trapped and depleted the oxygen in the water. Then, all the fish would suffocate." On Thursday, however, the DNR ruled out low dissolved oxygen, algal bloom or cold temperatures as the culprit for the fish death, according to The Sun. 
Mass animal deaths made headlines back in 2011 when thousands of animals were found dead in countries around the world. The mass deaths continued into 2012. Hundreds of Humboldt squid beached themselves near Santa Cruz, Calif., in December. In September, dead seagulls and fish washed ashore on Lake Eerie.- Huffington Post.

Over 350,000 Pounds Of Fish Died In Long Lake.
Area of dead fish in the Lake area, causing huge economic losses to local fishermen. According to the local Government's latest figures show that the fish killed more than 350,000 pounds, including deaths peak in October 3, 7th night of dead fish began to gradually reduce. It is understood that the dead fish later, local government and related departments have taken emergency measures management, organizing manpower to emergency disinfection of fishing and bury the dead fish. Xiaolu is a journalist in the area ran into a bit of downstream fishermen. He is new to cage, cage culture of less than two years. Xiaolu describes his cage in the fen village section of the hole in the lower area, built dams built power stations here. The Wengjiang River and other tributaries converge here, formed a huge Lake. Therefore, this time he farmed fish were not spared, more losses than upstream. "Throughout the vast expanse of the Lake and a stinker, is simply horrible. "Little land so describes the horrors of dead fish peak at that time. "No dead fish, more or less, I probably nearly 6,000 pounds of fish in cages. My losses are relatively small, losses more serious cases than me! Hey, just my luck, it lost two years...... "battered small land face down, he stood in the bow looking confused water, his eyes are filled with confusion. "Now I don't know what should I do in the future, this fish can continue to do?

A sudden hit Xiaolu negate efforts of father and son, but also completely destroy their confidence. 

It is understood that, in recent years, the rapid development of cage culture in the long Lake area, cage size and significant increase in the number and capacity in cages in the reservoir area is almost at saturation. According to the latest statistics from the local government data show, current cage culture in reservoirs there is approximately 180 households, more than 6,000 cage, deposit box fish probably around 4.5 million pounds. Xiaolu same part and many farmers, are shouted to the cage to make money and have acceded to or expansion of investment. Cage culture of sprawl and blindness makes area significantly increased risk. Yingde city animal husbandry and aquatic products Bureau told Xinhua, cage was farmers in the reservoir area of spontaneous, is difficult to control and master in number, only moderate to boot. However, the large area of abnormal fish mortality events, fishermen's losses are not just the fish in the cage, but also for many years has been adhere to breed confidence. - Shuichan [Translated].

Park officials said they’re not sure why or how the fish died but believe it is from natural causes, not something man-made.

The State Wildlife Department is planning to visit the park to conduct tests to see what is behind the die-off.

The lake remains open although it’s not exactly a good spot right now for a stroll beside the water. - KFOR.

In what authorities believe is one of the worst fish-kills in recent times, a lot of Curiass is being washed up on the Guyanese and Surinamese foreshores, apparently due to murky Atlantic Ocean waters and the discharge of freshwater into the sea.

The Fisheries Department of the Ministry of Agriculture says mostly dead Cuirass have been sighted since January 9 and the situation peaked on January 29 when a "significant amount of dead fish was observed on the beaches in the area. Consultations with Surinamese Fisheries Department officials have revealed that similar occurrences of dead fish have been observed in the vicinity of Nickerie and Coronie during the same period, the ministry here stated. "An on-the-spot observation conducted by the Regional Fisheries Officer revealed that the gills were heavily coated with sling mud and slime. This condition may have resulted in oxygen deprivation to the fish resulting in death," Guyana's Fisheries Department added.

While the observance of dead fish is said to be an annual occurrence by local fisherfolk in both countries, Guyana's Fisheries Department believes that this year's was "noticeably worse" and may have resulted from one of or a combination of factors. They include turbidity of the water in the area – caused by excessive rainfall in the general region resulting in excessive cloudiness of the water due to suspended particles from the rivers which flow into the ocean and reduced dissolved oxygen levels. The other major factor could have been a high fresh water discharge – the high discharge of fresh water from the rivers may have disrupted the salinity content of the water in the area which could adversely affect fish in the area.

The University of Guyana's Biodiversity Centre is expected to conduct tests on samples collected on January 22 to determine the cause of death of the fish. Results will be available several weeks later. The Fisheries Department said it was also conducting continuous water quality tests to determine the effects of the rainfall on the water quality in the area. According to officials, the situation has improved greatly since Sunday January 22 and Wednesday, with far less dead fish observed on beaches along the Upper Corentyne Coast. "The situation is being continually monitored by staff of the Fisheries Department," the Agriculture Ministry department said. - The Daily Herald.

The Ohio Division of Wildlife got a call on Sunday from a fisherman who told the agency they should probably come see the flood of fish carcasses in the Rocky River.
When they arrived, they discovered a waterway filled with dead aqua life. The fish kill is still under investigation. Today, the ODW announced the final death toll: 28,613 fish, along with other species. But the mere process of counting the dead was merely a first step. The interesting part, in terms of going after whoever was responsible for whatever caused the mass deaths (that's about as specific as we can get right now), comes next. 

Via the News-Herald:
“The investigators aren’t going back to the stream today because they believe they have all the data that they need,” said Jamey Graham, spokeswoman for the Wildlife Division’s District Three (Northeast Ohio) office in Akron. “They are now sorting the fish according to species and we should that information available soon.”

The reason for the separation of the fish by species is so that the Wildlife Division can determine how much to charge in fines and restitution if and when the culprit is identified. The state has assigned a dollar figure for each fish species.
