Cestodes of the Fishes of Otsego Lake and Nearby Waters
Cestodes of the fishes of Otsego Lake and nearby waters Amanda Sendkewitz1, Illari Delgado1, and Florian Reyda2 INTRODUCTION This study of fish cestodes (i.e., tapeworms) is part of a survey of the intestinal parasites of fishes of Otsego Lake and its tributaries (Cooperstown, New York) from 2008 to 2014. The survey included a total of 27 fish species, consisting of six centrarchid species, one ictalurid species, eleven cyprinid species, three percid species, three salmonid species, one catostomid species, one clupeid species, and one esocid species. This is really one of the first studies on cestodes in the area, although one of the first descriptions of cestodes was done on the Proteocephalus species Proteocephalus ambloplitis by Joseph Leidy in Lake George, NY in 1887; it was originally named Taenia ambloplitis. Parasite diversity is a large component of biodiversity, and is often indicative of the health and stature of a particular ecosystem. The presence of parasitic worms in fish of Otsego County, NY has been investigated over the course of a multi-year survey, with the intention of observing, identifying, and recording the diversity of cestode (tapeworm) species present in its many fish species. The majority of the fish species examined harbored cestodes, representing three different orders: Caryophyllidea, Proteocephalidea, and Bothriocephalidea. METHODS The fish utilized in this survey were collected through hook and line, gill net, electroshock, or seining methods throughout the year from 2008-2014. Cestodes were collected in sixteen sites throughout Otsego County. These sites included Beaver Pond at Rum Hill, the Big Pond at Thayer Farm, Canadarago Lake, a pond at College Camp, the Delaware River, Hayden Creek, LaPilusa Pond, Mike Schallart’s Pond in Schenevus, Moe Pond, a pond in Morris, NY, Oaks Creek, Paradise Pond, Shadow Brook, the Susquehanna River, the Wastewater Treatment Wetland (Cooperstown), and of course Otsego Lake.
