"Charles Darwin is known as the father of evolution, but in fact Alfred Wallace, another British naturalist, was a co-discoverer of the theory- though Darwin got the most credit"
It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.
eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.
The physical characteristics of an organism is its phenotype. I remember this because phenotype and physical both start with 'ph.'
Hope this helps. Good luck! :)
