Hello, Frank Indiviglio here. Involvement in exciting and important conservation work need not be limited to those select few fortunate enough to have turned their hobbies into careers. Especially in today’s economy, many vital research and recovery efforts rely heavily upon the work of volunteers. Getting out in the field (or pond, river and swamp, as the case may be!) is a wonderful way of expanding your fish-keeping horizons. Today I’d like to focus on fresh water species; I’ll cover marine fishes in the future.
Conserving Desert-Dwelling and other Rare Fishes
The North American Native Fish Association http://www.nanfa.org/ sponsors a number of conservation initiatives, all of which utilize volunteers. Particularly active in the conservation of desert spring fishes and others in similarly precarious habitats, current initiatives include assisting the US F&W Service in removing introduced plants, fishes, crayfish and bullfrogs from critical Moapa spring fish habitat, training university and government researchers in fish sampling techniques and participating in reintroduction efforts.
NANFA members also get to indulge their fish-keeping interests, establishing native fish aquariums in schools and nature centers and advising caretakers on husbandry and breeding techniques.
A Wide Range of Field and Captive Care Opportunities
The Native Fish Conservancy maintains an extensive collection of articles on native fishes and fish conservation. If you are unsure of where to start, a review of these would be invaluable in jump-starting the process and providing numerous options.
Through their “Adopt-A-Tank” program, NFC members also help schools set up and maintain native fish aquariums and assist students in sampling local fish populations…the best of both worlds!
Native Fresh Water Fishes in the Aquarium
Some of our smaller sunfishes have long been popular with aquarists in Europe, but in the USA native fish-keeping is a lost (or barely developed!) art. I do not quite understand why, as many are interesting, brilliantly colored and little-studied. Species diversity here is quite high…even over-crowded New York State boasts nearly 150 freshwater fishes, many of which do quite well in captivity (interesting note: more species of fish have been identified in the Amazon River than in the entire Atlantic Ocean!).
North America is populated by a wide variety of gorgeous sunfishes of all sizes (our massive large-mouth bass is, technically, a sunfish). With colors rivaling those of any tropical species and providing extensive care to their eggs and young, these are, along with yellow perch (please see photo), long-time aquarium favorites of mine. Another neglected species, the American eel, lived in my collection for 17 years, and a pair of brown bullheads that I bred in an outdoor pond provided a notebook-full of observations that I treasure to this day (males are unbelievably protective of their tadpole-like fry, herding them about for quite some time).
I’ll cover the care of various native fresh water fishes in future articles. Until then, please write in with your observations, experiences and questions. Thanks, Frank Indiviglio.
The US Fish & Wildlife Service currently lists nearly 150 species of native freshwater fishes as threatened or endangered. Information on each, along with links to recovery plans (some of which encourage volunteer participation), is posted at www.fws.gov/endangered/wildlife.html#Species.
The Cold Spring Harbor Fish Hatchery http://www.cshfha.org/ houses an extensive collection of fresh water fishes, amphibians and reptiles, and is well-worth a visit by native fish enthusiasts.
