Default To replace with Carp?

If carp have a value then do you replace with carp?


Grand Island's kill one of largest on record By Tracy Overstreet

The killing of more than 10,000 fish last month because of water pollution from Grand Island was one of the most substantial human-induced kills in Nebraska.
"It is one of the largest on record," said Brian McManus, spokesman for the Nebraska Department of Environmental Quality.
McManus said there are three other major human-induced fish kills that occurred in the last 15 years.
In July 2006, more than 10,000 fish valued at $7,220 were killed in 15 miles of the Salt Creek near Roca. The fish died from exposure to ammonia, but the cause of the ammonia was never determined, McManus said.
In March 1995, hog waste discharged into the south fork of the Swan River near Tobias killed fish valued at $970. The kill stretched across more than 11 miles of river, he said.
Hog waste also caused the most prolific number of fish killed in 1993. More than 50,000 fish in eight miles of Spring Creek by Ruskin died. Although the fish numbers were high, the majority of the fish were small minnows and had a total value of $4,826.
DEQ field specialist Dave Bubb said hog waste in a river is fairly easy to trace back to its source.
"The river turns red," he said from bacteria in the waste that has a red cast.
Grand Island's pollution traced back to the city's wastewater treatment plant and meatpacker JBS Swift & Co. caused the killing of 10,626 fish last month. Bubb said the oxygen level in the water was exceptionally low and likely suffocated the fish in the water.
The majority of the killed fish nearly 9,000 were carp with an estimated value of $10,440. The total final value of the fish that were killed is still being calculated by the Nebraska Game and Parks Commission. Officials from DEQ and Game and Parks said Grand Island's kill, caused by a March 28 discharge, occurred over 24 miles of waterway. It included one-quarter mile of the city's wastewater treatment plant outfall ditch, 16.6 miles of the Wood River and 7.5 miles of the Platte River. McManus said natural fish kills also occur from time to time. Most recently was the loss of 15 tons of fish estimated to total 20,000 to 30,000 in number at the Kearney water retention structure near the south edge of Kearney. That kill happened due to the shallow water being iced over for an extended period of time, which depleted oxygen in the water.
