     "text": "The Issue: Black carp are an invasive molluscivore in North America, originally transported to aquaculture facilities for their application as a biological control of snails in the 1980s. Since their introduction to the United States, escapes into the wild have been documented, and reproducing populations are now present in the Mississippi River basin. The greatest concern for black carp population expansion is the impact on native mussel and snail fauna, of which many species are already listed as threatened or endangered."

These sources provide valuable data on the growth, development, diet, and methods by which black carp may be collected. However, these opportunistic results lack a systematic sample design and may not be sufficient to document spread of this species."
