Fish Holding

Since the early 1970’s Alden has been on the fore front of fishery research with regards to fish passage and protection at power utilities.  An essential part of any fishery research study is healthy test fish.  These healthy organisms are the result of a successful aquaculture program. Alden's research has included many studies conducted with live fish that have produced design and operation criteria for various fish protection and passage systems that are in common use today.

State-of-the-art fish culture systems are available to ensure fish are maintained and cared for. The facilities (2 separate buildings) can hold a wide variety of fish species (freshwater, estuarine, and marine) and life stages (egg, larval, juvenile, and adult) in approximately 45 larger holding tanks and 85 larval tanks with over 11,000 gallons of water. 

Fish Species

Over the past several decades, 30 plus species of fish have been held and tested at Alden in a variety of adult and larval fishery  studies.  Alden maintains several adult re-circulating facilities; the largest of which holds 10,000 gallons. Additionally, Alden houses several larval facilities which are versatile enough to handle multiple species at once.
