“…In this case too, the SBR system output matches the results reported in the literature with the same species, % 0.27 mm s -1 (Larsen et al 2008), % 0.55 mm s -1 (Yúfera et al 2005), 0.66 mm s -1 (Korstad et al 1995), as well as with the freshwater B. calyciflorus: 0.34 mm s -1 (Preston et al 1999), 0.53 mm s -1 (Charoy et al 1995) and 0.47 mm s -1 (Charoy and Janssen 1999).…”

In this study, we investigated the possibility to improve a new behavioural bioassay (Swimming Speed Alteration test-SSA test) using larvae of marine cyst-forming organisms: e.g. the brine shrimp Artemia sp. and the rotifer Brachionus plicatilis. Swimming speed was investigated as a behavioural end-point for application in ecotoxicology studies. A first experiment to analyse the linear swimming speed of the two organisms was performed to verify the applicability of the video-camera tracking system, here referred to as Swimming Behavioural Recorder (SBR). A second experiment was performed, exposing organisms to different toxic compounds (zinc pyrithione, Macrotrol MT-200, and Eserine). Swimming speed alteration was analyzed together with mortality. The results of the first experiment indicate that SBR is a suitable tool to detect linear swimming speed of the two organisms, since the values have been obtained in accordance with other studies using the same organisms (3.05 mm s(-1) for Artemia sp. and 0.62 mm s(-1) for B. plicatilis). Toxicity test results clearly indicate that swimming speed of Artemia sp. and B. plicatilis is a valid behavioural end-point to detect stress at sub-lethal toxic substance concentrations. Indeed, alterations in swimming speed have been detected at toxic compound concentrations as low as less then 0.1-5% of their LC(50) values. In conclusion, the SSA test with B. plicatilis and Artemia sp. can be a good behavioural integrated output for application in marine ecotoxicology and environmental monitoring programs.

“…In this line, Guerritsen and Strickler (1997) Calanoid copepods demonstrated the adverse consequences of prey hyperactivity through enhancing the encounter rate of both individuals in natural waterbodies. On the other hand, it is probable that the consequent exhaustion of available energy and the increased physiological damage cause a reduction in swimming activity (Preston et al 1999). This reduction would reduce feeding efficiency, and hence, the energy available for general metabolism, growth and reproduction (Gliwicz 1990).…”

The purpose of this work was to experimentally analyze the impact of copper, chromium and a commercial pesticide with endosulfan on the escape behavior of two copepods (Notodiaptomus conifer, Argyrodiaptomus falcifer) and three cladocerans (Daphnia magna, Pseudosida variabilis and Ceriodaphnia dubia). The experimental assays were carried out using a novel hydraulic devise designed to mimic three-speed predator capture behavior. Two concentrations, one "high" and one "low", were employed and the exposure time was 15 (±5) minutes. With two exceptions, the species exposed to heavy metals manifested higher ability to escape than controls. Both concentrations of the pesticide reduced the escape ability of cladocerans but copepods responded, in general, in a similar manner as for heavy metals. The immediate apparent advantage of low and early toxic effects is discussed and the high sensitivity of the escape behavior suggests that it could be a complementary endpoint to be used in future ecotoxicological tests.

“…During body growth of Brachionus females from hatching to maturity, the size of corona also increases, but mature females with small variations in body size, weight and shape increase in mass due to egg deposition. Although there are several studies on rotifer locomotion (Viaud 1940in Cle´ment, 1977aCle´ment, 1977a;Wallace, 1980;Coulon et al, 1983;Luciani et al, 1983;Epp & Lewis, 1984;Stemberger & Gilbert, 1987;Snell et al, 1987;Charoy & Cle´m-ent, 1993;Janssen et al, 1993;Charoy, 1995;Korstad et al, 1995;Hagiwara et al, 1998;Preston et al, 1999;Santos-Medrano et al, 2001), information on swimming ability at the different stages of development is scarce.…”

Factors Affecting Swimming Speed in the Rotifer Brachionus plicatilis

This study examines the swimming speed in amictic females of Brachionus plicatilis in laboratory cultures. Five different stages were examined: recently hatched females, juveniles, adult non-ovigerous females, ovigerous females with 1 attached egg and ovigerous females with 2 attached eggs. We tested the speed at two temperatures, 15°C and 25°C, and two feeding conditions, presence and absence of microalgal cells. An automated motion analysis system was used to measure speed which was then video recorded. Swimming speed (lm s )1 ) increased with increasing body size. There was a slight decrease in the speed of adult females as the number of attached eggs increased. Swimming activity was higher at 25°C than at 15°C and in the absence of food than if microalgae were present. Average values under the different experimental conditions ranged between 500 lm s )1 for the recently hatched and fed females and 1500 lm s )1 for the adult non-ovigerous females in the absence of microalgae. Mass-specific swimming speed decreased with body mass increase.
