“…Prior to feeding trials, food was withheld for 1 wk to encourage prey drive and simulate natural starving periods (Frommen 2017). At the beginning of each trial (n = 35 trials), one L. macrochirus was randomly transferred to a transparent 1-L aquarium and allowed a 2-h acclimation period prior to feeding.…”

Carbonaceous nanomaterials, such as fullerenes (C60, C70) and the derivative phenyl‐C61‐butyric acid methyl ester (PCBM), have promising application in solar energy technologies. Although the acute ecotoxicity of C60 has been reported widely in the literature, ecotoxicity assays for different fullerene forms and broader ecosystem impact studies remain scarce. To address these knowledge gaps, acute, chronic, and life stage exposure studies with freshwater zooplankton, Daphnia magna and Daphnia pulex, were performed for each material. Experimental results indicated that C60 and PCBM are not acutely toxic at estimated environmentally relevant concentrations; however, C70 had significant acute effects. All forms of fullerene caused a gradual elevation in heart rate over time and visual darkening of the Daphnia spp. carapace. The impact of fullerenes on susceptibility to predation was then assessed experimentally by presenting D. pulex to the visual predator Lepomis macrochirus (bluegill). Predation risk was significantly increased in fullerene‐exposed D. pulex. The present study underscores the need to broaden the scope of traditional ecotoxicity for emerging materials: studies are required that evaluate portfolios of related nanomaterials and that capture chronic and cascading ecosystem‐level effects.

“…For example, they remove sick or dead embryos from their reproductive organs to reduce the spread of disease, and also cannibalize offspring that are underdeveloped. This avoids providing additional energy for their care, and the energy saved by the parents' cannibalism can be used to care for the remaining offspring or for future reproductive activities (Frommen 2017). In natural environments, parents may cannibalize their offspring merely to ensure the continuation of the population.…”

Cannibalism refers to maiming and killing among individuals of the conspecifics, and plays a key role in controlling animal population numbers and ensuring reproduction (i.e., eliminate the waste of food and space by weaker individuals). However, cannibalism in aquaculture directly reduces the survival rate and the production of farmed animals. Therefore, reduction in the incidence of cannibalism in farmed aquatic animals has been of great interest to the aquaculture industry. In this paper, we review factors affecting the cannibalistic behavior of aquatic animals and the research progress on the screening of shelters to prevent cannibalism. These shelters focus on the animals and their external environment. We also discuss prospects for future research. The purpose of this review is to provide a scientific reference for the study of cannibalistic behavior of aquatic animals and a theoretical basis for the development of cannibalism-preventing shelter technologies for aquatic animal farming.
