Doug Sweet

Doug has been a fish culturist/hobbyist for about 45 years. He started off with a goldfish bowl, graduating to a ten-gallon tank, and finally confiscating a corner of his parent’s basement for a dozen tanks.

Doug acquired a Bachelor of Science Degree in Zoology from Michigan State University (MSU). Don Garling, Professor of Fisheries (Aquaculture) at MSU commandeered Doug to work on a Masters of Science degree studying fish nutrition. Doug’s work included attempts to develop diets for larval walleye and whitefish. Later in his graduate career, he worked on manipulating fish genetics. Specifically, inducing triploidy in Chinook, coho and Chinook-coho salmon reciprocal hybrids. He also worked on triploid induction in bluegills.

Doug’s previous position (for 19 years) was Curator of Fishes for the Belle Isle Aquarium-Detroit Zoological Institute. While holding this position he oversaw the breeding and rearing of more than thirty species of endangered fishes from around the world including Mexican goodeids, pupfishes, Lake Victorian Haplochromines, and other southwestern United States imperiled species. He also became involved in freshwater mussel conservation and culture and conducted freshwater mussel surveys in southeastern Michigan and propagation trials of several native freshwater mussels (fat-muckets, lilliputs, purple lilliputs and wavy-rayed lamp mussels).

During the last eight years he has been Superintendent for the London State Fish Hatchery in London, Ohio. The hatchery produces brown trout, rainbow trout, muskellunge, and hybrid striped bass for stocking public waters of Ohio.

Doug has a soft spot in his heart for highly domesticated fishes such as Siamese fighting fish and fancy goldfish. Also a long term passion for trying to find the spawning triggers of kuhli loaches. When it comes to angling, Doug considers himself still a “kid”, preferring the action of bluegill and other pan-fish on hook and line in the spring.
