PURPOSE: To characterize food webs of freshwater fish communities using stable isotopes DESCRIPTION: Data set containing the carbon, nitrogen, and sulphur stable isotope ratios of fishes caught in the Northwest Miramichi River system PARAMETERS COLLECTED: Species gut contents (ecological); species isotopic signatures (ecological); points (spatial) PHYSICAL SAMPLE DETAILS: Powdered animal tissue SAMPLING METHODS: Invertebrates were sampled via kicknet and were collected 1-4 meters from the shore of each location in one-minute intervals with 5-10 intervals per site. Fish were captured using a variety of net types in order to maximize sampling breadth. Please see below for list of net types and mesh sizes: Large fyke (box, lead line, and cod = 5mm tight, 10mm loose); 6mm beach seine; Site 3: two small fyke nets (box, lead line, and cod = 17mm, 17mm and 10mm tight, and 32mm, 32mm, 20mm loose), one trap net (box = 47.6mm and lead line = 146mm) were used). USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
