Scientists collect water samples from the waterways and use molecular techniques to extract and analyze the DNA of carp that is present in the water.
Here's why:
* eDNA is shed by organisms: Carp, like all living things, shed DNA into their surroundings. This can include skin cells, scales, mucus, and even waste products.
* Water samples capture eDNA: By collecting water samples from the waterways, scientists can capture this eDNA.
* Molecular techniques isolate and identify: Using specialized laboratory techniques, scientists can isolate and amplify the carp DNA from the water samples. This allows them to identify the presence of carp in the area.
