BONY FISHES 602 Bony Fishes
click for previous page BONY FISHES 602 Bony Fishes GENERAL REMARKS by K.E. Carpenter, Old Dominion University, Virginia, USA ony fishes constitute the bulk, by far, of both the diversity and total landings of marine organisms encoun- Btered in fisheries of the Western Central Atlantic.They are found in all macrofaunal marine and estuarine habitats and exhibit a lavish array of adaptations to these environments. This extreme diversity of form and taxa presents an exceptional challenge for identification. There are 30 orders and 269 families of bony fishes presented in this guide, representing all families known from the area. Each order and family presents a unique suite of taxonomic problems and relevant characters. The purpose of this preliminary section on technical terms and guide to orders and families is to serve as an introduction and initial identification guide to this taxonomic diversity. It should also serve as a general reference for those features most commonly used in identification of bony fishes throughout the remaining volumes. However, I cannot begin to introduce the many facets of fish biology relevant to understanding the diversity of fishes in a few pages. For this, the reader is directed to one of the several general texts on fish biology such as the ones by Bond (1996), Moyle and Cech (1996), and Helfman et al.(1997) listed below. A general introduction to the fisheries of bony fishes in this region is given in the introduction to these volumes. Taxonomic details relevant to a specific family are explained under each of the appropriate family sections. The classification of bony fishes continues to transform as our knowledge of their evolutionary relationships improves. -
Fish Passage and Injury Risk at a Surface Bypass of a Small-Scale Hydropower Plant
sustainability Article Fish Passage and Injury Risk at a Surface Bypass of a Small-Scale Hydropower Plant Josef Knott, Melanie Mueller, Joachim Pander and Juergen Geist * Aquatic Systems Biology Unit, Department of Ecology and Ecosystem Management, Technical University of Munich, Mühlenweg 22, 85354 Freising, Germany; [email protected] (J.K.); [email protected] (M.M.); [email protected] (J.P.) * Correspondence: [email protected]; Tel.: +49-816-171-3767 Received: 14 October 2019; Accepted: 29 October 2019; Published: 30 October 2019 Abstract: In contrast to the efforts made to develop functioning fishways for upstream migrants, the need for effective downstream migration facilities has long been underestimated. The challenge of developing well-performing bypasses for downstream migrants involves attracting the fish to the entrance and transporting them quickly and unharmed into the tailrace. In this study, the acceptance of different opening sizes of a surface bypass as well as the injuries which fish experience during the passage were examined. Overall bypass acceptance was low compared to the turbine passage. There was no significant difference in the number of downstream moving fish between the small and the large bypass openings. Across all fish species, no immediate mortality was detected. Severe injuries such as amputations or bruises were only rarely detected and at low intensity. Scale losses, tears and hemorrhages in the fins and dermal lesions at the body were the most common injuries, and significant species-specific differences were detected. To increase bypass efficiency, it would likely be useful to offer an alternative bottom bypass in addition to the existing surface bypass. -

Giorgieri, 5-34127 Trieste, Italy; [email protected] (S.G.); [email protected] (M.G.) * Correspondence: [email protected] † Equal contribution. Abstract: Transposable elements (TEs) represent a considerable fraction of eukaryotic genomes, thereby contributing to genome size, chromosomal rearrangements, and to the generation of new coding genes or regulatory elements. An increasing number of works have reported a link between the genomic abundance of TEs and the adaptation to specific environmental conditions. Diadromy represents a fascinating feature of fish, protagonists of migratory routes between marine and fresh- water for reproduction. In this work, we investigated the genomes of 24 fish species, including 15 teleosts with a migratory behaviour. The expected higher relative abundance of DNA transposons in ray-finned fish compared with the other fish groups was not confirmed by the analysis of the dataset considered. The relative contribution of different TE types in migratory ray-finned species did not show clear differences between oceanodromous and potamodromous fish. On the contrary, a remarkable relationship between migratory behaviour and the quantitative difference reported for short interspersed nuclear (retro)elements (SINEs) emerged from the comparison between anadro- mous and catadromous species, independently from their phylogenetic position. -

Bestor Department of Anthropology and East Asian Institute Columbia University Introduction As an anthropologist specializing in Japanese studies, I am often struck by the uncharacteristic willingness of economists to consider cultural and social factors in their analyses of Japan. Probably the economic system of no society is subject to as much scrutiny, analysis, and sheer speculation regarding its 'special character' as is Japan's. Put another way, emphasis on the special qualities of the Japanese economy suggests a recognition -- implicit or explicit -- that cultural values and social patterns condition economic systems. It remains an open question whether this recognition reflects empirical reality (e.g., perhaps the Japanese economic system is less autonomous than those in other societies) or is an artifact of interpretative conventions (e.g., perhaps both Western and Japanese observers are willing -- if at times antagonistic - partners in ascribing radical 'otherness' to the Japanese economy and therefore are more likely to accord explanatory power to factors that might otherwise be considered exogenous.) Recognition, however, that Japanese economic behavior and institutions are intertwined with and embedded within systems of cultural values and social structural relationships does not imply unanimity of opinion about the significance of this fact. -

But if you know where to look, Tokyo can be tamed. he power of Tokyo lies in everything there you couldn’t find in another country: modern living and ancient Ttraditions, high-tech gadgets and cheeky cartoon mascots, old-fashioned manners and futuristic impulses.

It’s a city that is notoriously difficult to navigate (many streets have no names), but taxi drivers will get you where you need to go with the aid of the GPS systems installed in every cab. It’s one of the safest cities in the world, where six-year-old girls are often seen walking alone to and from school.
