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. -

This type of tail primitively results from an ontogenetic fusion of centra (bodies of vertebrae) and the possession of paired bracing bones located bilaterally along the dorsal region of the caudal skeleton, derived ontogenetically from the neural arches (uroneurals) of the ural (tail) centra. -

A NEW PIPEFISH FROM QUEENSLAND. By A. FRASER-BRUNNER, F.Z.S., British Museum (Natural History), and G. P. WHITLEY, F.R.Z.S., Curator of Fishes, Australian Museum. (Figures 1-2.) When drawing some types of Australian fishes in the British Museum, the senior author found a specimen of a Queensland Pipefish which did not agree with Gunther's , type (from Suez) of the species (Acentronura tentaculata) with which it had been previously ~ssociated .(Duncker, 1915; McCulloch and Whitley, 1925; Dollfus and Petit, 1938). He prepared a description and figure of the specimen, and sent them to the junior author, who studied the fish in relation to the literature and made taxonomic comparisons with its congeners. The specimen is considered to belong to a new species. Family SYNGNATHIDAE. Genus ACENTRONURA Kaup, 1853. Acentronura breviperula, sp. novo (Figure 1.) Length of head contained 2!! times in head plus trunk. Snout equal to diameter of eye, half as long as postorbital part of head. Tail about 1~ times length of combined head and trunk. Thirteen body rings; 42 tail rings, the first seven of which form the brood-pouch. Dorsal fin on 4!! rings, two of which are caudal. Dorsal rays 16; pectoral 15.

Generally, in this group, the upper jaw consists of the premaxilla, maxilla, and supramaxilla. The lower jaw consists of the dentary, anguloarticular, retroarticular, and sesamoid articular. In higher taxa, the premaxilla bears ascending, articular, and postmaxillary processes. The maxilla usually bears a ventral and a dorsal articular process. The supramaxilla is present only in some taxa. The dentary is usually toothed and bears coronoid and posteroventral processes. The retroarticular is small and located at the posteroventral corner of the anguloarticular.

In “The Secret Lives of Seahorses,” the Monterey Bay Aquarium’s new special exhibition, you’ll discover that nothing could be further from the truth. Beginning April 6, more than 15 species of seahorses, sea dragons and pipefish will beckon visitors into the elusive world of these charismatic creatures. The Secret Lives of Seahorses highlights the varied habitats in which seahorses and their relatives live, and shares important stories about the threats they face in the wild. “Seahorses are wonderful ambassadors for ocean conservation because they live in the most endangered habitats in the world – coral reefs, sea grass beds and mangrove forests,” said Ava Ferguson, senior exhibit developer for The Secret Lives of Seahorses. “When you save a seahorse, you also save some of Earth’s most precious marine habitats.” Through wrought-iron gates, visitors will enter the first gallery, “Seahorses and Kin,” and meet the seahorse family: fishes that have fused jaws and bony plates in place of the scales normally associated with fish. -

Detrital shadows: Evaluating landscape and species effects on detritus-based food web connectivity in Pacific Northwest estuaries Emily Russell Howe A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2012 Reading Committee: Charles Simenstad, Chair Daniel Schindler Andrea Ogston Program Authorized to Offer Degree: School of Aquatic and Fishery Sciences ©2012 Emily Russell Howe ii iii University of Washington Abstract Detrital shadows: evaluating landscape and species effects on detritus- based estuarine food web connectivity in Pacific Northwest estuaries Emily Russell Howe Chairperson of the Supervisory Committee: Charles A. Simenstad School of Aquatic and Fishery Sciences Estuaries are inherently open systems, linking together terrestrial, aquatic, and marine ecosystems. With fluid, permeable transitions (ecotones) marking the boundaries between these ecosystems, estuaries subsidize coastal food web productivity through the mediation of nutrient, material, and energy flux across ecosystem boundaries. Mechanisms governing the strength and scale of estuarine detritus-based food web connectivity, however, are poorly understood. For example, early estuarine descriptions suggest that extensive mixing and large-scale transport of organic matter occurs within estuarine systems, while recent evidence in estuarine detritus-based food webs has shown strong spatial gradients in the sources of organic matter assimilated by consumers across a diversity of scales. This suggests food webs are spatially compartmentalized in some estuaries, but strongly connected in others. Given that estuaries have experienced extensive structural and hydrological alterations over the past century, research describing the mechanisms of estuarine-supported subsidies is necessary if we are to provide informed guidelines for the conservation and restoration of estuaries and estuarine functions. -

Zoological Studies 51(8): 1490-1506. This study reports on (1) variations in the number and position of scleral ossicles in 283 actinopterygian species representing 172 families, (2) the distribution of the morphological variants of these bony elements, (3) the phylogenetic significance of these variations, and (4) a phylogenetic hypothesis relevant to the position of the Callionymoidei, Dactylopteridae, and Syngnathoidei based on these osteological variations. The results suggest that the Callionymoidei (not including the Gobiesocidae), Dactylopteridae, and Syngnathoidei are closely related. This conclusion was based on the apomorphic character state of having only the anterior scleral ossicle. Having only the anterior scleral ossicle should have evolved independently in the Syngnathioidei + Dactylopteridae + Callionymoidei, Gobioidei + Apogonidae, and Pleuronectiformes among the actinopterygians studied in this paper. http://zoolstud.sinica.edu.tw/Journals/51.8/1490.pdf Key words: Scleral ossicle, Actinopterygii, Phylogeny.
