“…Due to the comparatively large spatial scale of habitat use by many fishes, the extent to which alien macrophyte invasion affects a fish assemblage may often be dictated by the invasion's scale (Keast, 1984). As well as potentially impacting individual movement and refuge, the impacts of alien macrophyte invasion on fishes are expected to depend strongly on the effects of that invasion on prey taxa abundance and availability (Bickel & Closs, 2008; Carniatto et al, 2020; Dibble & Harrel, 1997). Alien macrophyte invasion may also affect fish assemblage structure by altering interspecific interactions between fishes (Schultz & Dibble, 2012).…”

“…Studies on H. eques have been carried out using various approaches, such as toxicological corrections (Marcon et al, 2016;Mansano et al, 2018;Abe et al, 2019), assessment of eating behavior (Carvalho & Del-Claro, 2004;Pelicice & Agostinho 2006), reproduction and development (Park et al, 2014;Çelik & Cirik, 2019), parasitic fauna (Santos et al, 2017;Narciso et al, 2019), genetics and cytogenetics (Martinez et al, 2012;Piscor & Parise-Maltempi, 2015;Costa-Silva et al, 2018), food preferences (Miraldo & Pecora, 2017;Carniatto et al, 2020), and dietary supplementation (Pan et al, 2011;Berchielli-Morais et al, 2015). However, deficiencies in the information concerning this fish have been frequently addressed (Carvalho & Del-Claro, 2004;Park et al, 2014;Acosta & Silva, 2015;Çelik & Cirik, 2019;Santana et al, 2019).…”

Hyphessobrycon eques has a great prominence in fishkeeping and scientific research. In this context, a systematic literature review was performed to assist in the improvement of captive breeding of this species and to identify knowledge gaps. Notably, of the 966 articles published between 1997 and 2020 found in an initial screening of the digital libraries of Google Scholar, PubMed, SciELO, Science Direct, and Scopus, only 56 represented research on the species according to the established criteria. Considering aspects pertinent to captive reproduction, 25 studies were selected. These studies addressed information regarding reproduction; embryonic, larval, and juvenile development of the species; parasitic fauna; limiting concentrations of prophylactic agents; food preferences; and dietary supplements already used for these fish. Only seven studies reported information on the physicochemical characteristics of water in natural habitats, with great variations in several parameters, mainly those related to temperature. In 5 of the 25 selected studies, information related to reproductive characteristics and/or embryonic, larval, and juvenile development was addressed. However, only two studies developed experimental studies with information relevant to the captive breeding of the species. Studies to identify parasitic fauna and to analyze the use of prophylactic agents were also found. As for the information gaps on the cultivation of the species, there are no studies related to nutrition seeking to determine the species nutritional needs, including feeding frequencies, feeding durations, and specific amounts of food. Therefore, this review offers a great support for the breeding of H. eques by highlighting opportunities for new scientific studies that could enrich and collaborate in the breeding of this ornamental fish.

“…Largemouth bass ( Micropterus salmoides ) was introduced around the same period as L. macrochirus and interfered with their establishment by consuming L. macrochirus ; however, the high quantity of aquatic macrophytes that is supported by Korean wetlands greatly hindered the predatory activities of M. salmoides and contributed to the stable establishment of L. macrochirus [ 29 ]. Although various empirical studies have suggested that vegetated areas are highly effective as refuges for zooplankton because plants negatively affect the fish foraging activities [ 31 , 32 , 33 ], vegetated areas with larger L. macrochirus populations only have a minor refuge effect [ 29 ]. The presence of predators in existing refuges requires novel defense strategies that are clearly different from the existing strategies of prey such as zooplankton.…”

The Use of Winter Water Temperature and Food Composition by the Copepod Cyclops vicinus (Uljanin, 1875) to Provide a Temporal Refuge from Fish Predation

Frequent predation induces various defense strategies in prey, including morphological changes or migration patterns in zooplankton. We hypothesized that the winter dominance of Cyclops vicinus in the Upo Wetlands, South Korea, is an evolved temporal defense mechanism to avoid fish predation. Long-term data (2014–2019) showed that fish consumed the most cyclopoid copepods from spring to autumn. Lepomis macrochirus preferentially consumed C. vicinus; thus, C. vicinus density was lower from spring to autumn. However, C. vicinus was abundant in winter when fish consumed fewer copepods. Nauplii density began to increase in late autumn (October–November), and their population growth was fueled through consumption of Cyclotella sp. and Rhodomonas sp. Culture experiments showed that Cyclotella sp. contributed more to the growth stage (copepodite or subadult) after nauplii than Rhodomonas sp. C. vicinus density was lower in the winters of 2013 and 2016 when the densities of these phytoplankton prey species were lower. In summary, although winter conditions were suitable for copepod survival and population growth, C. vicinus relied heavily on the diversity and species composition of its food sources. The winter dominance of C. vicinus could increase regional biodiversity and contribute significantly to the stability of the freshwater food web.
