Need to check if the New Hampshire trout hatchery will deliver sometime in May.
The choice centered around Bluegill, Trout, Goldfish, Koi, or Tilapia.
Bluegill - no local sources. I could fish for these myself at Redd's Pond, but that would have been time consuming and you can't be sure what some of my Marblehead Liberal Neighbors would squawk about if they saw me hauling away 5 gallon pails of live fish.
Tilapia - a favorite for aquaponics, but it is a warm water fish and I intend to keep the fish outside in the cold weather.
Goldfish - widely available at local and on-line sources, but boring and the trout are actually less expensive.
Koi - cool fish but wicked expensive. They are probably a good choice despite this because of their longevity - 20 yrs or more.
Rainbow Trout - hardy cold water fish. Very pretty to look at. would make a tasty meal if we elected to harvest them. And if my research is correct, I can have them delivered rather inexpensively from HY-ON-A HILL TROUT FARM in Plainfield, NH.
So Rainbow Trout gets the nod. I feel they are more resilient than Brook Trout and better to look at than Brown Trout.
