A dataset of the macroinvertebrates collected for a trout production study from August 2017- August 2018 in northern New Mexico. The invertebrates are sampled from the benthos, drift, and trout stomachs (via gastric lavage). The drift and benthic invertebrate data represent subsampled individuals. There is a separate file that documents the percent of original sample. The diet samples were not subsampled. The dataset includes individual invertebrates identified to taxonomic Order, lifestage, habitat, their measured lengths, and regressed dry masses.
Benthic and Drift invertebrate samples were processed by two parties. Some of the samples were subsampled according to a standardized protocol in order to be processed more efficiently. This dataset includes the information that is necessary for "scaling up" the invertebrate data to concentration in square meters (benthic) or cubic meters (drift).
