Fifty years later: trophic ecology and niche overlap of a native and non-indigenous fish species in the western basin of Lake Erie

Fish assemblage structure has changed dramatically in the Western Basin of Lake Erie since Trautman’s revision of the Fishes of Ohio. Fish surveys near the Bass Islands and adjacent mainland tributaries documented fish faunal distributional patterns during the last three decades. Recent collections (n=1,719 sites) from 1982-2014 indicate that 123 fish species are extant and 27 species have been extirpated from the Bass Islands and nearby tributaries draining the western basin. Extirpation of Polyodon spatula, Alosa sapidissima, Moxostoma lacurum, and Sander glacum occurred; however, A. sapidissima and members of genus Oncorhynchus were introduced and unable to naturalize. Recent collection of A. fulvescens in Schoolhouse bay near Middle Bass Island in May 2012; Umbra limi populations on Middle Bass Island and Kelley’s Island; and Lepisosteus oculatus populations along the southeastern shoreline of North Bass Island are stable in Lake Erie despite increased eutrophication. The current Western Basin fish assemblage includes 107 native, 26 nonindigenous, and 6 alien fish species. Twenty-one native species have been extirpated from Lake Erie, while 6 nonindigenous species have not naturalized and have been extirpated. Six additional species known from within the Lake Erie basin have not been collected from the Western Basin during the study period and current status is unknown. Introduced non-indigenous and alien species are responsible for increased species richness including Neogobius melanostomus, Proterorhinus semilunaris, Salmo trutta, Carassius auratus, Cyprinus carpio, Ctenopharyngodon idella and four records for Hyphthalmichthys molatrix since 1981. Brief comments on distribution, relative abundance, and status are provided for each species.

Marked Decline

Competition among native and non-native species can cause decreases in population size and production of both species. The native predaceous crustacean zooplankter Leptodora kindtii shares a similar niche with the invasive Bythotrephes longimanus in Lake Erie. This niche overlap may contribute to the decline in abundance and production of Leptodora in the western basin of Lake Erie. Historical (1946) and recent (2006) data were used to determine if the decline in Leptodora abundance and production was associated with the effects of Bythotrephes, which invaded Lake Erie in the mid-1980’s. Pre-invasion abundances and lengths of L. kindtii were compared with current data (2006). A change in prey community abundance, composition and dynamics were observed, relative to pre-invasion, with a marked decline in.abundance and size of L. kindtii after the invasion of Bythotrephes. Competition for food and direct predation are two explanations, among others, for the declines observed in L. kindtii size, abundance and production that have occurred since B. longimanus invasion.

Information on trophic ecology can provide an understanding of the functional role of fish in an ecosystem, including endemic and native fish groups, as well as alien fish that are introduced through anthropogenic activities. The research on the trophic ecology of the fish community in the Nimbai Stream, Prafi River system, is intended to describe the interaction of competition and predation, especially towards endemic fish, Melanotaenia arfakensis. Fish samples were collected monthly from four habitat types, i.e., slow littoral, medium littoral, pool, and run from May 2016 to April 2017. A combination of an electric shocker and a hand net was used to collect fish samples. A total of 16 fish species were collected, consists of one endemic species, namely M. arfakensis, nine species of native fish, and six species of alien fish. The Arfak rainbowfish and three native fish species were categorized as insectivorous, four native fish species as herbivorous, and two other fishes as carnivorous. Three alien fish species also belong to insectivorous, two alien fish species as carnivorous, and one species as herbivorous. The niche breadth of fish communities ranges from 0.071 to 0.857. The trophic niche overlap between the Arfak rainbowfish and three native fish species and three alien fish species was recorded. The results of this study indicate a potential competition and predation interactions between Arfak rainbowfish and native fish as well as with alien fish species. Therefore, introducing alien fish into Prafi River system will disrupt Arfak rainbowfish population.

Maumee River, the major tributary in the western basin of Lake Erie, serves as one of major sources of freshwater in the area, supplying potable, recreational, and industrial water. In this study we collected water samples from four sites in the Maumee River Bay between 2016–2017 and E. coli was isolated, enumerated, and analyzed for antimicrobial resistance (AMR) and multidrug resistance (MDR). Strikingly, 95% of the total isolates were found to be resistant to at least one antibiotic. A very high resistance to the drugs cephalothin (95.3%), ampicillin (38.3%), tetracycline (8.8%), gentamicin (8.2%), ciprofloxacin (4.2%), cefoperazone (4%), and sulfamethoxazole (1.5%) was observed within isolates from all four sampling sites. Percentages of AMR and MDR was consistently very high in the summer and fall months, whereas it was observed to be lowest in the winter. A remarkably high number of the isolates were detected to be MDR—95% resistant to ≥1 antibiotic, 43% resistant to ≥2 antibiotics, 15% resistant to ≥3 antibiotics, 4.9% resistant to ≥4 antibiotic and 1.2% resistant to ≥5 antibiotics. This data will serve in better understanding the environmental occurrence and dissemination of AMR/MDR in the area and assist in improving and establishing control measures.

Lontra Longicaudis

Lontra longicaudis (Olfers, 1818) (Carnivora, Mustelidae) is a semi-aquatic animal spread through the Central and South America, except in Chile. The implantation of a hydroelectric power plant along a river alters the dynamics of the watercourse, transforming a lotic environment into a lentic or semilotic one, what can damage the otter's feeding. From April 2008 to March 2009 we analysed the otter's food habits in lotic (streamlet) and semilotic (hydroelectric reservoir) environments of Paranapanema Valley, in southeastern Brazil. Aiming to compare the otter's diet of these two environments, we analyzed statistically the frequency of occurrence of main items in the scats. Fishes represent the base of the diet both in the reservoir and in the streamlet and, despite of the total otter's diet showing up similarities in the two environments, the results evidenced modifications on the fish species consumed between them. In the reservoir the otters ate more exotic fish Oreochromis niloticus (Linnaeus, 1758) probably because it is an easy capture prey in this place. The fact that the otters get established and feed in the reservoir doesn't mean that this structure is benefic to the species because the food supplied for it consists mainly of exotic fish species.
