“…Martins et al [72] stated low trophic niche overlapping between two fish species suggests a stable coexistence developed by both species, which allowed them to reach great abundance in the region. However, high overlap values may not indicate competition since species can adopt different strategies to overcome competence.…”

The present study objectified to evaluate the trophic relationships among 14 fish species (10 natives and 4 non-natives) in the Shatt Al-Arab River, considering the trophic niche breadth and the diet overlaps of the species. The food items in the stomach of each species are determined by adopting the index of relative importance (IRI). The dietary analysis revealed a total of 12 types of major food items consumed (which represent >10% IRI). Two species (Oreochromis aureus and Cptodon zillii) were herbivores consumed mostly macrophytes, algae and diatoms. Four species (Planiliza abu, P. klunzengeri, P. subviridis and Osteomugil speigleri) were herbivores mainly fed on diatoms, macrophytes, detritus and algae. Three species (Carasobarbus luteus, Carassius auratus and Cyprinus carpio) were omnivores mostly consumed macrophytes, detritus, diatoms and algae. Two species (Tenualosa illisha and Nematalosa nasus) were filter feeders fed largely on zooplankton, algae, detritus and macrophytes. Three species (Acanthopagrus arabicus, Johnius belangerii and J. dussumeiri) were carnivores mainly preyed on shrimps, crabs and fish. Levin’s index diet breadth analyses divided the studied fish species into three categories; two species with high specialization, five species with low specialization, and seven species with generalization feeders. The dietary composition of fish species exhibited 62 diet overlaps as indicated by the Jaccard index, eight of them high, 36 moderate and 18 low overlaps. Only J. dussumeiri and J. belangerii have no diet overlap with other species. Overall, the study demonstrates that most trophic overlaps between species were moderate, but high degree overlap was between the native species (C. luteus) and invading species (C. auratus) and therefore strengthen earlier conclusions regarding interspecific competition between these two species.

“…The Whitemouth croaker (Figure 4) has a wide distribution range, spanning from the Yucatán Peninsula (Mexico, 28ºN) to the Gulf of San Matías (Argentina, 41ºS) (Cousseau and Perrota 2013). This broad distribution can be attributed to the eurythermal and euryhaline characteristics of the species, enabling it to adapt to various habitats, exhibit reproductive plasticity (Franco et al 2019), and display trophic plasticity (Martins et al 2017). The species' diverse feeding habits suggest its potential participation as an intermediate or definitive host in parasitic transmission systems in tropical regions (Marcogliese 2002).…”

Local Ecological Knowledge of artisanal fishers (Caiçaras) was employed to investigate various biological aspects of the Whitemouth croaker (Micropogonias furnieri) in the Sepetiba Bay, in the state of Rio de Janeiro. This included migration patterns, reproduction, feeding habits, and interactions such as parasitism. Semi-structured interviews were carried out with 40 fishers in two communities using the “snowball” technique. It was found that the fisher’s information coincides with the academic literature for some aspects of the biology and ecology of the species. Furthermore, the fishers provided descriptions of novel patterns, which contributed to a deeper understanding of the species' natural history. These included observations of reproduction occurring almost throughout the entire year, the influence of east and north winds on the species' entry into the bay, interactions with marine catfish (Ariidae), and notable records of the isopod Cymothoidae as an important parasite of the Whitemouth croaker. This study contributes new insights to the ecological understanding of this fish species, which holds significant socio-environmental importance. It also documents changes in the livelihoods of artisanal Caiçaras communities resulting from the increasing anthropogenic activities in the region. Finally, it highlights the species' significance in terms of its sale and consumption within these communities, owing to its relative abundance in the area, despite the environmental impacts.

“…Fish ecology studies provide information on species biology and the dynamics of aquatic ecosystems. This in turn contributes to the development of measures for the conservation and management of fishery resources (Braga et al 2012, Martins et al 2017. Fish present different adaptations in their feeding habits, usually associated with spatial and seasonal changes in food availability (Wooton 1992).…”

Diet and resource sharing by two Pimelodidae species in a Southeastern Brazilian reservoir

et al. 2019

Fish can vary their diet and feeding dynamics according to biotic and abiotic factors. There is insufficient knowledge regarding these factors in reservoirs, which limits the management of these areas. The aim of this study was to determine the diet of two related and most collected fish species, verify the influence of biotic and abiotic factors on their diet, and also verify the existence of resource sharing by them in an upstream Brazilian reservoir. Fish abundance in the reservoir was calculated and data were provided by 176 specimens of Iheringichthys labrosus (Lütken, 1874) and 255 specimens of Pimelodus maculatus Lacépède, 1803 collected in Camargos reservoir, MG, Brazil. Stomach contents were analysed through the frequency of occurrence and volumetric methods. PERMANOVA analysis was done to evaluate the influence of biotic (Species and Size class) and abiotic factors (Season and Site) on the diets. The Alimentary Index (AI) and feeding overlap Index (Pianka) were also estimated. A NMDS analysis was conducted to visualize the food categories responsible for interspecific difference. The ingested items were grouped into 18 categories, of which 17 were found in both species. Feeding resources were significantly related to the biotic (Species: Pseudo F = 2.583, P = 0.001; Size Class: Pseudo F = 1.646, P = 0.001) and abiotic (Season: Pseudo F = 2.458, P = 0.006) factors. I. labrosus showed an invertivorous diet while P. maculatus an omnivorous diet and both species were not exclusively benthophagus as typically reported. Food overlap occurred intraspecifically and interspecifically (Pianka 0.61 to 0.97 and 0.61 to 0.66, respectively) and overlap also occurred in three of the four analysed seasons (Pianka 0.66 to 0.91). The diet overlap found between two of the most fished species and the low fish productivity may indicate the limitation of resources in this reservoir and should be considered for management of this area.
