a biotechnology called edna survellance allows scientist to test water samples for the presence of the dna of the invasive fish species. why could this technology be more effective in protecting native fish populations than traditional methods of sampling areas for invasive species using nets?

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.

100 dollars because yeah

the denominator has a very specific role.
