Distributional Ecology of the Cisco (Coregonus Artedii) in Indiana' Distributional Ecology of the Cisco (Coregonus artedii) in Indiana' DAVID G. FREY Indiana University ABSTRACT The cisco is known with considerable certainty to occur in 41 lakes of northern Indiana, of which Shriner Lake at a latitude of 41° 14' N. is the southernmost known natural occurrence of the family Coregonidae. There are three and possibly more in- stances where lakes with cisco populations several decades ago no longer contain the species, presumably as a result of altered limnological conditions. The few recorded attempts at stocking the cisco in lakes in which they did not otherwise occur have apparently been quite uniformly unsuccessful, and it is concluded that the pre- Columbian distribution has not been extended by man's activities. The species generally occurs in the deep water of a lake in summer. As oxygen conditions become progressively more severe, the population is forced into the upper part of the hypolimnion, and finally into the lower or even the upper part of the thermocline. It is assumed in this paper that the species can tolerate water tempera- tures as high as 20° C., and an oxygen content as low as 3 ppm., or possibly even slightly • lower. As the species is forced progressively higher in the lake it comes into increas- ingly greater content with species of fish commonly occurring in the epilimnion, and may even be preyed upon by the bowfin and the northern pike. The summer bathymetric distribution of the species in several Indiana lakes was determined by means of gill nets, and in the other lakes it was inferred from the ex- tremes of temperature-oxygen stratification of summer. Data available for 37 cisco lakes as compared with 53 non-cisco lakes demonstrate that in general the cisco lakes have a thicker stratum of water with temperatures below 20° and an oxygen content greater than 3 ppm. The shallower cisco lakes tend to have an oxygen maximum in the thermocline, and in one lake such a photosynthetic maximum has occurred regularly over four successive summers. This type of oxygen distribution is believed significant in enabling the species to survive in small and shallow lakes. The facts that the cisco lakes in Indiana occur in definite clusters and that these lakes tend to have a different type of oxygen distribution than the non-cisco lakes point to the importance of regional geologic and geomorphic controls in the limnology of the lakes and consequently in the persistence of cisco populations in them.

Except for its absence from Greenland, the group is continu- ously circum-boreal in distribution. The southernmost latitudinal limit of the natural distribution of the family is reached in the lake district of northern Indiana (Meek 1916:136) and in fact, the southernmost known natural occurrence of the family is in Shriner Lake in Whitley County, Indiana, at a latitude of 41° 14' N. The various types of coregonids are so plastic in their phenotypic expression that almost every lake has its own particular race, nation or subspecies of the species concerned. The most widely distributed coregonid in the glacial lakes of the northern United States and Canada is the cisco, Core gonus artedii Le Sueur. This species extends through the glaciated portion of the United States at least from New York to Minnesota, and in Canada it extends northward to Hudson Bay and environs (Dymond 1933) and northwestward into the Yukon and Northwest Territories (Dymond 1943). This is a pelagic, plankton-feeding species with a terminal mouth, 179 belonging to the subgenus Argyrosomus of the European terminology. Like the other members of the genus it has been considered to be a cold stenotherm requiring a fairly high level of dissolved oxygen, although its oxygen requirement is apparently less demanding than in the whitefishes. The present study, however, demonstrates that local cisco populations can be much more tolerant of high temperatures and low concentrations of oxygen than is commonly assumed. The phenotypic plasticity of the cisco is demonstrated by the fact that Koelz (1931) recognized 24 groups (subspecies) within this one species, although Hile (1936b and 1937) later concluded that there was insuf- ficient basis for establishing these infra-species categories. Moreover, as Hile pointed out, there is a considerable environmental control of pheno- typic expression, so that, for example, different year classes within a single body of water are able to differ significantly from one another in various morphometric characters. The present study is concerned particularly with the distribution of the cisco, and the factors controlling its distribution. If we assume for North America, as Thienemann (1950) has done for several of the core- gonids in northern Europe, that in late-glacial, or at least by early post- glacial, time all the glacial lakes (including ice-block basins without out- lets?) in the appropriate watersheds contained ciscoes, then the absence of the cisco from particular lakes must have resulted from the develop- ment of conditions unsuitable for the continued survival of the species. Thienemann (1918) concluded for Coregonus maraena in northern Ger- many that the species was eliminated from certain of these lakes as the oxygen content of the hypolimnion declined to certain minimum values, accompanying the natural typological aging

Public domain. Available: http://eol.org/data_objects/26779416. (June 2017). 1 Native Range, and Status in the United States Native Range From Froese and Pauly (2017): “Europe: In the Baltic Sea: Swedish coast (including Bothnian Gulf, not in Gotland); in southern Baltic, extending from the Schlei to Gulf of Finland. Southeast North Sea Basin: Ems, Weser and Elbe drainages 1 and small rivers of Schleswig-Holstein and Denmark. Landlocked in several lakes in Poland, Sweden, and Russia.” Status in the United States From Neilson (2017): “Failed introduction.” “A shipment of 409 individuals from Lake Miedwie (formerly Madue Lake), Poland was stocked in Garnder Lake, Michigan in 1877 (Baird 1879; Todd 1983).” Means of Introductions in the United States From Neilson (2017): “Coregonus maraena, along with other species of Coregonus, was intentionally stocked as a food fish by the U.S. Fish Commission (Todd 1983). According to Baird (1879), 1,000 eggs of C. maraena were shipped from Poland to Michigan in 1877 and hatched in captivity at the State Hatching House in Detroit. A total of 409 of the young fish were stocked in Gardner Lake (Baird 1879; Todd 1983). Baird (1879) considered the stocking an experimental introduction of a European food fish.” Remarks From Neilson (2017): “There is much confusion regarding the identity of whitefish imported from Germany in the late 1800s by the U.S. Fish Commission, primarily due to the uncertain taxonomy and systematics of Coregonus (Kottelat and Freyhof 2007).

Juli 2015 Diese Dissertation ist auf den Internetseiten der Universitätsbibliothek online verfügbar Erklärung Ich versichere, dass ich diese Doktorarbeit selbständig und nur unter Verwendung der angegebenen Hilfsmittel angefertigt habe. Weiterhin versichere ich, die aus benutzten Quellen wörtlich oder inhaltlich entnommenen Stellen als solche kenntlich gemacht zu haben. Lara Ibrahim Aachen, am 18 März 2015 Zusammenfassung Die Zulassung von Pflanzenschutzmitteln in der Europäischen Gemeinschaft verlangt unter anderem eine Abschätzung des Risikos für Organismen in der Umwelt, die nicht Ziel der Anwendung sind. Unvertretbare Auswirkungen auf den Naturhalt sollen vermieden werden. Die ökologische Risikoanalyse stellt die dafür benötigten Informationen durch eine Abschätzung der Exposition der Organismen und der sich daraus ergebenden Effekte bereit. Die Effektabschätzung beruht dabei hauptsächlich auf standardisierten ökotoxikologischen Tests im Labor mit wenigen, oft nicht einheimischen Stellvertreterarten. In diesen Tests werden z. B. Effekte auf das Überleben, das Wachstum und/oder die Reproduktion von Fischen bei verschiedenen Konzentrationen der Testsubstanz gemessen und Endpunkte wie die LC50 (Lethal Concentrations for 50%) oder eine NOEC (No Observed Effect Concentration, z. B. für Wachstum oder Reproduktionsparameter) abgeleitet. Für Fische und Wirbeltiere im Allgemeinen beziehen sich die spezifischen Schutzziele auf das Überleben von Individuen und die Abundanz und Biomasse von Populationen.

Acta Ichthyologica et Piscatoria 51(2): 139–144. https://doi.org/10.3897/aiep.52.64119 Abstract The maraena whitefish, Coregonus maraena (Bloch, 1779), is often considered a suitable candidate for intensive aquaculture diver- sification in the EU. However, only a few such farms in Europe are in operation. Rearing this species in recirculating aquaculture systems is a recent innovation, and optimisation is necessary to standardise aspects of larviculture. This 30-day study investigated the effect of stocking densities of 25/L, 50/L, 100/L, and 200/L on the survival and growth of maraena whitefish larvae in a recirculating aquaculture system.

  • Metabarcoding Approach to Identifying Early Life Stages of Great Lakes Fishes
    Metabarcoding approach to identifying early life stages of Great Lakes fishes by Kavishka Gallage A thesis submitted in conformity with the requirements for the degree of Master of Science Ecology and Evolutionary Biology University of Toronto ãCopyright by Kavishka Gallage 2020 Metabarcoding approach to identifying early life stages of Great Lakes fishes Kavishka Gallage Master of Science Ecology and Evolutionary Biology University of Toronto 2020 Abstract Accurately identifying fishes in their early life stages using morphology is challenging, time-consuming, and requires taxonomic expertise. Metabarcoding is a method that can be used to identify species in batch samples (Cruaud et al. 2017). Detection of early life stages of fishes is important for understanding life history patterns and critical spawning habitat. In this study, metabarcoding is used as an identification tool to identify 1119 egg and larva batch samples from Sydenham River and Rondeau Bay. I identified 34 species from Sydenham River and 8 species from Rondeau Bay and the spawning months of these species based on date of capture. I determined the materials and supplies cost of metabarcoding in this study to be $6597.33, compared to $62289.09 for individual-based barcoding. This study shows the potential of metabarcoding as a broad-scale detection and identification method for early life stages of Great Lake fishes. ii Acknowledgements Many people contributed to the completion of my Master’s thesis through academic and emotional support. First, I would like to thank my supervisors Dr. Nicholas Mandrak and Dr. Nathan Lovejoy for their continuous support throughout the duration of my thesis. I am grateful for opportunity to work with you and learn from you.

PATTT.O %o.S- S3. LONDON: PRINTED BY ORDER OF THE TRUSTEES. 1866. PBEFACE. DK. GUNTHEB observes,—" This volume contains the continuation of the families of Physostomi. At the commencement of my account of this order it was my intention to adopt it with the limits assigned to it by Muller, and to distinguish the Scombresoces as a distinct order, viz. Malacopterygii pliaryngognathi; however, during the progress of a detailed examination of these fishes so many points of affinity with the Cyprinodontes became apparent, that I was reluctantly obliged to deviate still more from Muller's ordinal division. " The Salmonidae and the vast literature on this family offer so many and so great difficulties to the Ichthyologist, that as much patience and time are required for the investigation of a single species as in other fishes for that of a whole family. The ordinary method followed by naturalists in distinguishing and determining species, is here utterly inadequate; and I do not hesitate to assert that no one, however experienced in the study of other families of fishes, will be able to find his way through this labyrinth of varia­ tions without long preliminary study, and without a good collection for constant comparison.

Since the late 1980s, several re-establishment programs have been implemented in rivers draining into the North Sea, but the scientific basis for sustainable conservation measures is often lacking, since little is known about the biology of this species. In this study, otolith microchemistry of fish ranging from 24.6 to 58.4 cm in total length (median 31.3 cm, SD 8.4 cm) was used to characterize the migration behavior of a reintroduced population of maraena whitefish from the River Elbe, Germany. Our analyses re - vealed the presence of 3 different migration patterns: (1) one-time migration into high-salinity habitat (North Sea) within the first year of life (29.6%), (2) multiple migrations between low- and high-salinity habitats starting in the first year of life (14.8%) and (3) permanent residency within low-salinity habitats, a pattern displayed by the majority (55.6%) of sampled individuals.
