“…Diptera are a diverse and abundant group of insects, and are found in almost all water sources owing to a wide larval range (Keiper et al 2002;Skevington and Dang 2002). Furthermore, in addition to their availability and abundance, the nutritional value of dipteran insects renders these an important prey species, as evidenced by the feeding habits of several freshwater shes (Nath et al 2017;Gülbunar et al 2018). The results of the current study suggest that members of Diptera were a major and readily available food source for G. a nis in lentic habitats.…”

To understand the success of non-native sh invasions, it is important to clarify their tolerance to habitat differences and their adaptations to these habitats with regard to feeding habits. In this study, the invasive characteristics of the non-native sh Gambusia a nis were examined in order to determine its growth and feeding habits in different habitats (lotic and lentic). Fish specimens were collected from October 2021 to November 2022 from the Nakaibori Stream (lotic) and from May to December 2022 from the Nagatsugawa Reservoir (lentic). Growth indices (total length: TL, eviscerated weight: EW, and condition factor: CF) for both habitats showed that TL and EW were signi cantly lower for lotic than for lentic habitats. However, the CF of the lotic habitat was higher than that of the lentic habitat. The vacuity index (VI) for the lotic habitat was more than ve times higher than that for the lentic habitat. The food range of G. a nis in the lentic habitat comprised 14 food items, which mainly included members of Diptera. However, in the lotic habitat, only eight of these were consumed, with members of Formicidae being the most common, followed by plants (mostly lamentous algae). Zooplankton were not consumed in the lotic habitat. Both the lotic and lentic habitats had relatively low niche breadths (0.39). The feeding strategy of G. a nis was determined to be closely related to changes in habitat prey assemblages and possibly indicates competition for food with native sh species.

“…Diptera and Trichoptera played the most important role in the diet of B. cyclolepis and the domination of dipteran larvae in the diet of other species of barbels was also reported from many studies (Collares-Pereira et al, 1996;Piria et al, 2005;Rozdina et al, 2008;Sapounidis et al, 2015). Dipterans are one of the most abundant macroinvertebrate groups in freshwater environments and these prolific organisms produce large populations (Keiper et al, 2002;Gülbunar et al, 2018). Dipteran larvae sometimes attach themselves to structures on the bottom but are often free-swimming and suspended off the bottom.…”

The aims of the study are to determine what the organisms Barbus cyclolepis consume as food in its feeding environments and to compare prey consumption with prey abundance in the environment. The study was conducted in the Istranca Stream located in Istanbul (Turkey) during the spring and summer of 2012. A total of 142 B. cyclolepis specimens were captured and it is determined that 94 of them had full digestive tracts. Diet analyses of B. cyclolepis showed that its food spectrum consisted of 11 different food types, and the species was found to feed on insects, mainly Diptera (IRI%= 92.26%). The most abundant macroinvertebrate organisms in the environment were Diptera and Gastropoda. The electivity index of B. cyclolepis was positive for Diptera in the spring (E= 0.49), but the value was below the expected value of 0.6 for high selectivity. The electivity values for other macroinvertebrate groups, consumed in low proportions, were negative. In summer, the fish fed on Diptera, Plecoptera, and Trichoptera, but a high electivity index value was found only for Trichoptera (E= 0.87). Results showed that B. cyclolepis mainly consumed Diptera as food and did not consume Gastropoda, although it is the second most abundant macroinvertebrate group in the environment. A relationship was determined between the proportion of food groups consumed in the digestive tracts of fish and the ratios of macroinvertebrates in the environment, and as a result, it was specified that the fish was selective on Diptera.

“…Tanypus punctipennis is a midge with distribution in all world regions except Australia [38]. T. punctipennis has a wide Palearctic distribution in temperate climates, consistent with its possible presence in the Great Lakes [39]. The late instar larvae of T. punctipennis are relatively small [40] compared to larger genera such as Chironomus and Ablabesmyia annulata.…”

Chironomids are one of the most biodiverse and abundant members of freshwater ecosystems. They are a food source for many organisms, including fish and water mites. The accurate identification of chironomids is essential for many applications in ecological research, including determining which chironomid species are present in the diets of diverse predators. Larval and adult chironomids from diverse habitats, including lakes, rivers, inland gardens, coastal vegetation, and nearshore habitats of the Great Lakes, were collected from 2012 to 2019. After morphological identification of chironomids, DNA was extracted and cytochrome oxidase I (COI) barcodes were PCR amplified and sequenced. Here we describe an analysis of biodiverse adult and larval chironomids in the Great Lakes region of North America based on new collections to improve chironomid identification by curating a chironomid DNA barcode database, thereby expanding the diversity and taxonomic specificity of DNA reference libraries for the Chironomidae family. In addition to reporting many novel chironomid DNA barcodes, we demonstrate here the use of this chironomid COI barcode database to improve the identification of DNA barcodes of prey in the liquefied diets of water mites. The species identifications of the COI barcodes of chironomids ingested by Lebertia davidcooki and L. quinquemaculosa are more diverse for L. davidcooki and include Parachironomus abortivus, Cryptochironomus ponderosus. Parachironomus tenuicaudatus, Glyptotendipes senilis, Dicrotendipes modestus, Chironomus riparius, Chironomus entis/plumosus, Chironomus maturus, Chironomus crassicaudatus, Endochironomus subtendens, Cricotopus sylvestris, Cricotopus festivellus, Orthocladius obumbratus, Tanypus punctipennis, Rheotanytarsus exiguus gr., and Paratanytarsus nr. bituberculatus.
