The team of researchers provides an easy-to-follow methodical description on how to measure standard metabolic rate (SMR), routine metabolic rate (RMR), maximum metabolic rate (MMR), and aerobic scope (absolute and factorial) as well as how to assess the regulation index, P50, and Excessive Post Hypoxia Consumption (EPHOC) data in larval toadfish (Opsanus beta) over a range of their environmental temperatures. In addition to the detailed materials and method section, the authors supply the article with a manageable overview on how to analyze such respirometry data and which data parameters to include. The data are effectively illustrated using an assortment of data graphs, plots, and tables.
