Traditional analysis of gut content and droppings relies on the visual identification of food items which can be challenging further along the digestion process. DNA analysis only requires a small subsample and can detect even trace amounts of food species DNA. We offer target DNA analysis where we scan the presence of specific species e.g. the invasive Round Goby (Neogobius melanostomus). More holistic food web analysis can be achieved with DNA meta analysis which provides a list of all species present in the sample.
