“…Marked feeding pressure of P. parva on zooplankton under the carp-pond conditions was described by , Adámek & Sukop (2000) and Oberle (2003) and under the experimental conditions by Hanazato & Yasuno (1989), Chang et al (2004) and Nagata et al (2005). However, the results from fishponds in this study documented even more drastic impact on whole zooplankton communities.…”

“…Horák fishpond was used as a control locality without additional feeding of carp and thus large Cladocera were depressed soon after their spring abundance maximum in 2004. Chironomid larvae are a common component of the food of P. parva (Muchačeva 1950;Guirca 1970;Adámek & Siddiqui 1997;Xie et al 2000;Hliwa et al 2002;Nagata et al 2005). Although Baruš et al (1995) and especially Wolfram-Wais et al (1999) and Declerck et al (2002) reported that chironomids were significantly preferred by P. parva, the influence of P. parva presence on density of chironomid larvae has not been clearly proved in this study.…”

“…described a great impact of P. parva on pond zooplankton and zoobenthos composition. Hanazato & Yasuno (1989), Chang et al (2004) and Nagata et al (2005) described that P. parva directly controls large zooplankton species, namely Cladocera. The dominance of Daphnia and Bosmina in the diet of juvenile P. parva was described by Hliwa et al (2002).…”

Impact of topmouth gudgeon (Pseudorasbora parva) on production of common carp (Cyprinus carpio) — question of natural food structure

Four production fishponds in the Czech Republic were investigated in 2003 and 2004 during a feeding experiment on common carp (Cyprinus carpio). In 2003, topmouth gudgeon (Pseudorasbora parva) was detected in enormous amounts in all of the investigated fishponds. P. parva got into the fishponds spontaneously by water inflow from connecting channels. The objective of this paper is to describe the condition of natural food in the presence of P. parva and its subsequent effect on carp production. The estimation of the population density of P. parva achieved at least 44 kg ha −1 in 2003. In 2004, precautions against P. parva invasion were taken and its presence wasn't recorded during the season. The impact of P. parva on natural food structure was described in terms of zooplankton and zoobenthos amounts and main fish production parameters. A special focus has been taken on the density of Daphnia genus and chironomid larvae, the most preferred zooplanktonic and zoobenthic groups in feed of P. parva, respectively. In 2003, P. parva suppressed the zooplankton populations significantly, especially large cladocerans of the Daphnia genus. Influence of P. parva on zoobenthos structure and density was not detectable. Unfavorable natural food condition in 2003 caused extremely low carp production which fell to the mean value of 283 kg ha −1 and food conversion ratio reached 3.5. On the contrary, in 2004 the mean carp production and food conversion ratio attained 634 kg ha −1 and 1.6, respectively. The results described harmful competitive effect of huge populations of P. parva and its surprising economic consequences. Costs per 1 kg of growth were increased by approximately 100% in 2003 compared with results from season 2004.

“…4). This result differs from that of many other studies in which larval fish significantly suppressed the abundance of cladoceran zooplankton (Dettmers and Stein 1992;Nagata et al 2005). The difference might not be due to larval size (namely gape size), because the gape size of the larval pond smelt was almost 0.6 mm at the end of the experiment.…”

The predation impact of the larvae of pond smelt Hypomesus transpacificus nipponensis on a zooplankton community was studied using mesocosms. The fish significantly depressed the abundances of copepod nauplii and rotifers, especially Hexarthra mira. The vulnerabilities of these prey might be determined by their swimming behavior and population density, suggesting that larval fish selectively prey on zooplankton that have a high encounter rate with the predator. The larvae did not have a negative effect on the densities of cladocerans, but fish predation altered the cladoceran community structure from the dominance of B. longirostris to that of B. fatalis. This result suggests that larval fish predation is an important factor that shifts the species composition of Bosmina in some lakes, the shift occurring in the season when fish larvae are abundant. Our results have shown that predation by the larval fish would control not only the abundance, but also the community structure of the small-sized zooplankton prey.

“…Predator^prey studies usually focus on changes in prey abundance due to predation (Mills, Green & Schiavone Jr 1987;Persson & Greenberg 1990;Wu & Culver 1994;Spencer, Potter, Bukantis & Stanford 1999;Gliwicz et al 2004;Nagata, Ha & Hanazato 2005;Makrakis et al 2008; but see Slusarczyk 1997). In this study, we sought to evaluate primarily the importance of a size-selective predator's density on its prey's life-history sizes.…”

Decreasing trophic efficiency in cool-water aquaculture ponds: size-selective predation removes large prey

Maximizing young-of-year (YOY) ¢sh production in an aquaculture setting depends on matching predatory demand with prey availability. With a size-selective YOY ¢sh species (saugeye: Sander vitreus Mitchell females Â S. canadense Gri⁄th & Smith males) supplied with natural zooplankton prey (Bosmina sp. Baird), selective removal of larger individuals may decrease prey fecundity. However, increased nutrient fertilization may also ameliorate the top-down e¡ects of ¢sh predation. We tested these interactions in outdoor earthen production ponds (ca. 4000 m 2 ; n 512) by measuring Bosmina sp. size at ¢rst reproduction (SFR), maximum size (MAX) and neonate size (NEO) in ponds that varied in YOY saugeye densities (18^50 saugeye m À 3 ) and also di¡ered in phosphorus maintenance levels (either 20 or 30 mg PO 4 -P L À 1 ). We found that SFR decreased by 8% [from 0.298 mm AE 0.007 (mean AE 1SE) to 0.275 mm AE 0.005], MAX decreased by 11% (from 0.367 mm AE 0.009 to 0.328 mm AE 0.009) and NEO decreased by 5% (0.198 mm AE 0.004 to 0.189 mm AE 0.003) over the range of saugeye densities, and that SFR increased by 4% (from 0.279 mm AE 0.004 to 0.290 mm AE 0.003) and MAX increased by 3% (from 0.336 mm AE 0.004 to 0.347 AE 0.004) with increased fertilization. Further, prey o¡spring lengths strongly related to mother lengths and lengths di¡ered from early to late in the production season. These results indicate that multiple factors a¡ect prey sizes and emphasize that the removal of large prey individuals by size-selective YOY predators may decrease trophic e⁄ciency, ultimately decreasing ¢sh production.
