Science activity

To better understand why the longfn smelt is threatened, the project compared the diet of larval longfn smelt to a thriving fsh with overlapping natal habitat and of similar size and morphology— the Pacifc herring. Using new genetic analysis methods, the project aimed to elucidate species composition of fsh diets in greater detail than has been done before and to measure diferences in composition and frequency of prey across habitats. In particular, the project aimed to identify prey items that were not previously seen using traditional diet analysis methods and assess whether any prey are indicative of natal habitats
