“…Behavioral end‐points, such as hops of Daphnia , are promising tools to assess ecologically relevant effects of contaminants, characterized by short‐term responses, high sensitivity, and noninvasiveness. Swimming behavior is a suitable and accurate endpoint for toxic assessment of rotifers (Faimali et al, 2017). Generally, the swimming angular speed and linear speed of rotifers were measured using the Swimming Behavioural Recorder System (SBR; Garaventa, Gambardella, Di, Pittore, & Faimali, 2010).…”

Titanium dioxide nanoparticles (nTiO2) have raised environmental concerns and display potential hazards to aquatic organisms and even humans. However, only a few reports tested the toxicity of nTiO2 to rotifers. In the present study, acute and chronic toxicity of nTiO2 to the freshwater rotifer Brachionus calyciflorus was investigated at different temperatures. At 25°C, the 24 and 48‐hr LC50 was 117.14 and 60.11 mg/L, respectively. At 15°C, 20°C, 25°C, and 30°C, exposure to nTiO2 significantly decreased life expectancy at birth, net reproductive rate, generation time, average lifespan, and/or intrinsic rate of population increase of B. calyciflorus (p < .05). High temperature enhanced the toxicity of nTiO2 to rotifers. The swimming linear speed of rotifers significantly increased (p < .05) in treatments with 200 µg/L nTiO2, compared with the control. In addition, treatments with 8 µg/L to 5 mg/L nTiO2 significantly increased superoxide dismutase activity (p < .05). Glutathione content and catalase activity increased significantly after exposure to 8 µg/L nTiO2 but decreased significantly in treatments with nTiO2 concentrations ranging from 40 µg/L to 5 mg/L (p < .05). There were no significant changes in malondialdehyde contents among nTiO2 treatments and control. Overall, the present study indicated that nTiO2 revealed high toxicity to rotifers, displaying high environmental risks to aquatic ecosystems.

“…Swimming activity in fish reflects a series of predictable physiological and biochemical responses of organisms related to environment. Some response changes may occur when there are alterations in water quality, which changes locomotion, reaction to predators, breathing and feeding (Faimali et al, 2016). This behavior may rise or lower energetic costs and, consequently, its metabolism (Ulianoet al, 2010).…”

“…An example of a more informative term is "seizure liability" as "incidence of high-speed movements characteristic of seizure activity" [30]. Although the quantitative determination of behavioural effects requires video tracking and elaborate analysis [105][106][107][108][109][110], the presence or absence of behavioural changes can easily be recorded in a standard FET test and be used as a first indicator of, e.g., a neurotoxic potential of the test compound [111].…”

Background The Fish Embryo Acute Toxicity (FET) test with the zebrafish (Danio rerio) embryo, the OECD test guideline (TG) 236, has been designed as an alternative for acute fish toxicity testing such as the OECD Acute Fish Toxicity Test (TG 203). To provide equivalent sensitivity to the acute fish test, the original FET test was designed to use only four morphological core endpoints: coagulation of the embryo, lack of somite formation, lack of heart beat, and non-detachment of the tail. These endpoints were selected due to (1) their association with mortality, directly or indirectly, (2) improve the practicality for screening by well-trained technical staff, and (3) the endpoints being relatively simple morphological alterations. Results With the growing need to understand the developmental toxicity of compounds found in the environment, the FET protocol has repeatedly been extended to a multitude of additional morphological endpoints that also allow the monitoring of teratogenicity. As the extensive use of the FET test has generated a multitude of observations in the scientific literature, a harmonisation of the terminology used for the description of the morphological effects seen after chemical exposure has become necessary. Conclusion For this end, the present communication provides an overview of both common and selected more specific morphological effects seen in zebrafish embryos after exposure to a wide variety of chemical substances together with suggestions for a harmonised nomenclature.
