Calculating distances between points for a large dataset

Hi, I am hoping that there might be an efficient way to calculate distances of points along a polyline.  My thoughts are that if I can snap GPS points to a polyline I can generate distances for a large dataset.  A little background to my dataset, I have GPS locations of fish that were radio-tracked over time.  I have an attribute table of coordinates, individual ID, and relocation number (e.g., 1st time located, 2nd time located).  Is there a way I can generate distances between tracking periods via the stream polyline?  There are a lot of tags and numerous tracking periods.  I would appreciate the time saving advice!
