What’s to not like about Asian carp? Nutritious, gentle and delicate in flavour, it may be filleted, deep-fried or minced into fish desserts—simply thoughts the bones. But Americans don’t take care of it. For starters, they confuse the fish with the widespread (or European) carp that could be a backside feeder, a much-maligned group. Yet tempting folks to eat extra Asian carp might enhance biodiversity in rivers throughout America’s South and Midwest. With a brand new marketing campaign, officers in Illinois hope to lure diners.

The carp was introduced from Asia within the Seventies to assist clear aquafarms in Arkansas. (They clear the water of plankton and algae, incomes them the identify of “filter feeders”.) From there they escaped into the Mississippi and propagated northward, outcompeting native fish species for meals. Now they’re considerable within the Illinois River. Ecologists fear they may evade limitations within the waterways round Chicago and enter the Great Lakes, decreasing the native fish range there.
In 2018 the Illinois Department of Natural Resources determined it will “recast” how Asian carp is perceived. Marketers had been introduced in. They cooked up a brand new identify, which was launched on June twenty second: copi (for copious). Nick Adam of Span, the company behind the rebranding, says the purpose was to shed the fish’s repute as one just for adventurous eaters. Focus teams described copi as “cute” and “manageable”.
Asian carp is just not the primary to get a makeover. The Patagonian toothfish is marketed in America as Chilean sea bass (it’s neither a bass nor native to Chile). The foul-sounding slimehead has been significantly better referred to as orange roughy for the reason that late Seventies. And managing invasive species by harvesting them is just not a novel thought both. The National Oceanic and Atmospheric Administration, a federal company, exhorts folks to eat lionfish, which threaten reefs alongside the Atlantic coast and within the Caribbean. Louisiana’s wildlife division affords recipes for nutria, a semi-aquatic rodent with an irrepressible breeding behavior. Ragondin à l’orange, anybody?
Lionfish is kind of well-liked, however its 18 venomous fin spines; the toothfish’s new identify was such successful that it arguably contributed to its overfishing. But proof is blended about whether or not harvesting to regulate an invasive species is efficient. With Asian carp, solely bigger fish are focused for human consumption. A examine by researchers at Michigan State University advisable that fishermen be given incentives to catch small ones too, to be used in fertiliser and fish meal.
But creating demand additionally dangers impeding efforts to cut back numbers. Prairie Rivers Network, an environmental group, has opposed the copi rebranding as a result of it appears to “incentivise a long-term sustainable carp fishery in Illinois waters”. Much will rely upon whether or not America’s gourmands cop on to copi.
