Thus, when young carp ‘seed’ were collected and stored in vats or the flooded compartments of river barges used for transporting live fish it is probable that bitterling were often exported with them.

This fish is caught in the following manner: nets are stretched along or across the stream and behind the net an arch-like (hollow) instrument is placed in the water with a little bell suspended in the upper part. When the fish hear the sound of this bell they stupidly rush towards it, being trapped together by the lowered nets. The above proves that this fish possess the sense of hearing. Those fish also like to carry out a kind of group dance, blushing with shame while dancing together. This is something they do (possibly) because it is a way to feed, or because it is a habit of theirs, or because this behaviour is triggered by the presence of others.

I Acknowledgements First of all I would like to thank my supervisor Doctor Carl Smith. With his support and professional expertise he has greatly contributed to my research experience helping me grow as a researcher and widening my knowledge of the animal world. I would like to thank Professor Martin Reichard of the Institute of Vertebrate Biology, Academy of Sciences of the Czech Republic. He has always heartily welcomed me in Brno, allowed me to use the facilities of his laboratory, and discussed my experimental work and results with insightful comments. A special thank also to Doctor Matej Polačik always ready to help and share his experience and knowledge of bitterling fish. A special thank to Professor S. Tarkan, Doctor Ö. Gayguzus, and Doctor E. Ercan for their help and hospitality in Turkey and for sharing pleasant dinners and after dinners in the guesthouse of Istanbul University in Sapanca. Many thanks to all the PhD students, postdocs and technicians at the Department of Biology of the University of Leicester, where I started my PhD, for their support, advice and friendliness. I am very grateful to all the members of the ‘fish group’ at the University of St Andrews that, during our ‘fish lunches’ at the Gatty, have presented their work- in-progress, discussed results and experimental designs, and given me precious advice for my research. I have learnt a lot from all of them. A special thank to Doctor Miguel Barbosa and Doctor Alfredo Ojanguren: chatting with them about mating systems, mating behaviours, and different ways of life has made cleaning tanks and filters in the aquarium a pleasant job. With Clara, Olivia, Reka, Ian, and Dani I have shared success and worries, coffee breaks, Friday night pub chats, even a hen night and a wedding. A very II hearty thanks to them all. I would like to thank also Muna Agbali: her love for science, her readiness to exchange knowledge and discuss problems, her friendliness and sympathy have made the years of my PhD course a very rich experience. Last, but not least, a very special thank to Matteo. He has patiently listened to endless stories about my bitterlings’ exploits, desperately tried to make me proficient at dealing with advanced computer technology, and, above all, has unconditionally offered me his precious support whenever I needed it.

The daily periodicity of microincrements forrned with the sagittal otoliths of these two spceies has been validated by oxytetracycline marking in previous studies. These validation studies have come from fishes within three regions of the Pacific (eastem, central and western tropical Pacific).

  • Genome Size Covaries More Positively with Propagule Size Than Adult Size: New Insights Into an Old Problem
    biology Article Genome Size Covaries More Positively with Propagule Size than Adult Size: New Insights into an Old Problem Douglas S. Glazier Department of Biology, Juniata College, Huntingdon, PA 16652, USA; [email protected] Simple Summary: The amount of hereditary information (DNA) contained in the cell nuclei of larger or more complex organisms is often no greater than that of smaller or simpler organisms. Why this is so is an evolutionary mystery. Here, I show that the amount of DNA per cell nucleus (‘genome size’) relates more positively to egg size than body size in crustaceans (including shrimp, lobsters and crabs). Genome size also seems to relate more to the size of eggs or other gametes and reproductive propagules (e.g., sperm, spores, pollen and seeds) than to adult size in other animals and plants. I explain these patterns as being the result of genome size relating more to cell size (including that of single-celled eggs) than the number of cells in a body. Since most organisms begin life as single cells or propagules with relatively few cells, propagule size may importantly affect or be affected by genome size regardless of body size. Relationships between genome size and body size should thus become weaker as body size (and the amount of cell multiplication required during development) increases, as observed in crustaceans and other kinds of organisms. Abstract: The body size and (or) complexity of organisms is not uniformly related to the amount of genetic material (DNA) contained in each of their cell nuclei (‘genome size’). This surprising mismatch between the physical structure of organisms and their underlying genetic information appears to relate to variable accumulation of repetitive DNA sequences, but why this variation has Citation: Glazier, D.S.

A. Yuldashov Institute of Fish Culture, 2, Universitet St., Kibray district, Tashkent region, Uzbekistan Abstract: Totally 47 alien fish species were introduced to Uzbekistan including 23 as target and 24 as accidental. One time introduction was carried out for health care; all other were done for fisheries purposes: (i) to the Aral Sea, (ii) to newly created irrigation water bodies, (iii) to aquaculture. Secondary settlement was marked for 27 species, for 20 species settlement was not found. Natural reproduction was marked for 31 species. At present 22 introduced species vanished in region; 7 species are not numerous, 20 species are numerous in water bodies. List of high value marketable fish includes 6 species, commercial – 18, trash fishes – 23 species. A number of introduced species did not find conditions for reproduction or could not survive and vanished. Several species survived and began to reproduce in the Aral Sea but vanished as salinity of water increased. Some species survived, but did not spread to another waterbodies. Several alien species have widely spread all over the Aral Sea basin; that’s happened after introduction of far eastern fishes in early 1960s. Keywords: introduction of alien fishes to Uzbekistan 1.

On 21 one side, bitterling exploit unionids by ovipositing in their gills. On the other side, unionids develop 22 via a larval stage (glochidium) that attach to fish gills. Both interactions are parasitic and expected 23 to have negative consequences for the host. Here we examined the effects of this association on the 24 metabolic rates of mussel and fish hosts by measuring oxygen uptake rates (MO2). Measurements 25 were performed on two widespread and broadly coexisting species; the rose bitterling Rhodeus 26 ocellatus and Chinese pond mussel Sinanodonta woodiana.

Abstrakt Cílem této práce je shrnout poznatky o reprodukčním chování hořavek (Acheilognathi- nae), hlavně pak hořavky duhové (Rhodeus amarus), a charakterizovat mechanizmy pohlav- ního výběru, na něj navazující párovací systémy a alternativní párovací taktiky. Pohlavní výběr, tedy ústřední téma této práce, zvýhodňuje určitého jedince před ostatní- mi jedinci stejného pohlaví a dělí se na intrasexuální a intersexuální. Intersexuální pohlavní výběr podléhá samičím preferencím, které se dají vysvětlit Fisherovou hypotézou, hypotézou dobrých genů či využitím smyslových vjemů. Z evolučního hlediska je pro samičky nezbytné maximalizovat svůj přímý a nepřímý zisk. Přímý zisk ovlivňuje samičku samotnou a může být ve formě rodičovské péče, svatebních darů, většího počtu oplodněných vajíček či kvalit- ního místa pro rozmnožování.
