Using Image Analysis Software to Assess American Eel (Anguilla rostrata) Elver Development
CCSEF was one of several sponsors of a recent presentation at Acadia University entitled “Using Image Analysis Software to Assess American Eel (Anguilla rostrata) Elver Development” and presented by Bailey Silver and Supervisors: Dr. Rod Bradford, DFO and Dr. Michael Stokesbury, Acadia University.
American eel (Anguilla rostrata) is a catadromous fish species that spawns in the Sargasso Sea. Larvae are transported to continental North America via the Gulf Stream and coastal currents. The run-timing (Figure 1) and run strength (Figure 2) of post-larval glass eels -or elvers- to non-tidal freshwater habitat varies among years and is influenced by a number of factors including time of arrival to the coastal zone, tidal influences, and local river conditions (e.g., flow, temperature).
