Efficacy of Using Electrofishing to Reduce Recruitment of Invasive Common Carp in Malheur Lake, a Large Endorheic Marsh
U.S. Fish and Wildlife Service Efficacy of using electrofishing to reduce recruitment of invasive Common Carp in Malheur Lake, a large endorheic marsh Final Report May 2017 By William Simpson, Doug Peterson , and Kurt Steinke Abernathy Fish Technology Center Longview, Washington Linda Beck1 Malheur Naonal Wildlife Refuge Princeton, Oregon 1 Current address: U.S. Fish and Wildlife Service, Fisheries and Aquac Conservaon, Portland, Oregon Adult Common Carp from Malheur Lake Developing embryos of Common Carp Abstract Concern about electrofishing inadvertently harming the embryos of species of conservation concern has motivated much of the research that describes what electrical conditions can kill fish embryos. As a result, targeted electrofishing might be underutilized as a potential control method to reduce the recruitment of nuisance or invasive fishes like Common Carp (Cyprinus carpio). Common Carp are one of the most widely distributed invasive fish in North America, and biologist are turning to integrated pest management techniques and targeting multiple life stages because control efforts based solely on removal of adults have often been unsuccessful. We examined changes in the survival of invasive Common Carp embryos while manipulating the transfer of electric power to the embryos by shocking them in water from carp-occupied areas using a variety of voltage gradient and waveform treatments produced by commercial electrofishing units and generators. Survival of electroshocked Common Carp embryos was < 50% at power densities (12,700 -

(2016): Distribution of invasive species Actinocyclus normanii (Hemidiscaceae, Bacillariophyta) in Serbia. – Studia bot. hung. 47(2): 201–212. Abstract: In Serbia Actinocyclus normanii was registered in several rivers and canals. In 1997, it was found as planktonic species in the Tisza River and in benthic samples (in mud) in the Veliki Bački Canal. In 2002, it was found as planktonic species in the Danube–Tisza–Danube Canal (Kajtaso- vo) and the Ponjavica River (Brestovac and Omoljica). Four years later, in 2006, the species was found in plankton, benthos and epiphytic samples in the Ponjavica River (Omoljica). A. normanii is a cosmopolite, alkalibiontic and halophytic species. It occurs in waters with moderate to high conductivity and it is indicator of eutrophied, polluted waters. Its spread could be explained by eutrophication of surface waters. Key words: Actinocyclus normanii, distribution, invasive species, Serbia INTRODUCTION An invasive species is a non-native species to a new area, whose introduction has a tendency to spread and cause extinction of native species and is believed to cause economic or environmental harm or harm to human, animal, or plant health. -

Diel Horizontal Migration of Zooplankton: Costs and Benefits Of
Freshwater Biology (2002) 47, 343–365 FRESHWATER BIOLOGY SPECIAL REVIEW Diel horizontal migration of zooplankton: costs and benefits of inhabiting the littoral R. L. BURKS,* D. M. LODGE,* E. JEPPESEN† and T. L. LAURIDSEN† *Department of Biological Sciences, University of Notre Dame, Notre Dame, IN, U.S.A. †Department of Lake and Estuarine Ecology, National Environmental Research Institute, Vejlsøvej, Silkeborg, Denmark SUMMARY 1. In some shallow lakes, Daphnia and other important pelagic consumers of phyto- plankton undergo diel horizontal migration (DHM) into macrophytes or other structures in the littoral zone. Some authors have suggested that DHM reduces predation by fishes on Daphnia and other cladocerans, resulting in a lower phytoplankton biomass in shallow lakes than would occur without DHM. The costs and benefits of DHM, and its potential implications in biomanipulation, are relatively unknown, however. 2. In this review, we compare studies on diel vertical migration (DVM) to assess factors potentially influencing DHM (e.g. predators, food, light, temperature, dissolved oxygen, pH). We first provide examples of DHM and examine avoidance by Daphnia of both planktivorous (PL) fishes and predacious invertebrates. 3. We argue that DHM should be favoured when the abundance of macrophytes is high (which reduces planktivory) and the abundance of piscivores in the littoral is sufficient to reduce planktivores. Food in the littoral zone may favour DHM by daphnids, but the quality of these resources relative to pelagic phytoplankton is largely unknown. 4. We suggest that abiotic conditions, such as light, temperature, dissolved oxygen and pH, are less likely to influence DHM than DVM because weaker gradients of these conditions occur horizontally in shallow lakes relative to vertical gradients in deep lakes. -

MAGYAR NYELVŐR 142. ÉVF. * 2018. ÁPRILIS–JÚNIUS * 2. SZÁM Dayka Gábornak Aorthographia címet kapott, kéziratban fennmaradt magyar nyelvű, nyelvészeti jellegű írásáról 1. Bevezetés. A tervem az, hogy a nyelvtudomány-történet keretében bemutas- sam a mindössze huszonnyolc évet élt, sajátos hangú 18. századi költőnek, Dayka Gábornak a kéziratban fennmaradt nyelvtani, egyáltalán nyelvészeti irányultsá- gú munkáit. A sorrendet illetően a Dayka-kutatáshoz alapot nyújtó Dayka Gábor Összes Művei című kötetet követem (az adatait l. DGÖM). Ez a kötet egyébként tartalmazza Dayka Gábornak – költői és prózai alkotásain kívül – a következő nyelvtani, nyelvészeti jellegű írásait: „Grammatikák és grammatikai jegyzetek: 1. Magyar nyelvű grammatikai tárgyú írások: a) Aorthographia és b) Grammati- kai feljegyzések. – 2. Proludium in Institutiones Linguae Hungaricae. – 3. Ternio Grammaticae Hungaricae 1794” (DGÖM 7). Meg kell jegyeznem, hogy bár e munkáknak se a pontos keletkezési idejét, se egymás utáni következésük sor- rendjét nem lehetett bizonyítottan megállapítani, a DGÖM-ben alkalmazott és idézett sorrend látszik logikusnak és követendőnek. A kötet tartalmazza az ere- deti szövegeken kívül – ha idegen nyelvűek – azok fordítását is, továbbá minden szöveg után a széles körű rálátással megírt jegyzeteket, amelyek megemlékeztek a kéziratról, az illető szöveg megjelenéséről, valamint közölnek szövegkritikát, és „Magyarázatok” címen tárgyalják az illető mű keletkezés- és fogadástörténetét, valamint közölnek számos fogalmat, jelenséget megvilágító megjegyzést. Egyéb- ként a filológusi feldolgozást a lehetséges teljességre, a rendszerességre, a minden lényeges kérdésnek az utánajárására, a logikus felépítésre, a pontosságra, valamint a világos megfogalmazásra való törekvés jellemzi (l. részletesen: DGÖM 64–9). Elöljáróban még szólok több éve tartó Dayka-kutatásaim első eredményé- ről, a Mi vitte Dayka Gábort, a költőt a nyelvtanírás, egyáltalán a nyelvtudomány felé? című tanulmányról (Szathmári 2016).
