Available in PDF, EPUB and Kindle. Book excerpt: THE DIVERSITY OF FISHES The third edition of The Diversity of Fishes is a major revision of the widely adopted ichthyology textbook, incorporating the latest advances in the biology of fishes and covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. Key information on the evolution of various fishes is also presented, providing expansive and conclusive coverage on all key topics pertaining to the field. To aid in reader comprehension, each chapter begins with a summary that provides a broad overview of the content of that chapter, which may be particularly useful for those using the text for a course who don’t intend to address every chapter in detail. Detailed color photographs throughout the book demonstrate just some of the diversity and beauty of fishes that attract many to the field. A companion website provides related videos selected by the authors, instructor resources, and additional references and websites for further reading. Sample topics covered and learning resources included in The Diversity of Fishes are as follows: How molecular genetics has transformed many aspects of ichthyology The close relationship between structure and function, including adaptations to special environments Many physical and behavioral adaptations reflecting the fact that many fishes are both predators and prey Fish interactions with other species within fish assemblages and broader communities, plus their impacts on ecosystems Global maps that more accurately represent the comparative sizes of oceans and land masses than maps used in prior editions For students, instructors, and individuals with an interest in ichthyology, The Diversity of Fishes is an all-in-one introductory resource to the field, presenting vast opportunities for learning, many additional resources to aid in information retention, and helpful recommendations on where to go to explore specific topics further.
Download or read book Systematics and Life History of the Great Barracuda Sphyraena Barracuda Walbaum written by Donald P. De Sylva and published by . This book was released on 1963 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The great barracuda, Sphyraena barracuda (Walbaum), family Sphyraenidae, is found in all tropical seas, with the exception of the eastern Pacific. The following nominal species are considered as synonyms of barracuda Walbaum, 1972: picuda Bloch and Schneider, 1801; becuna Lacèpéde, 1801; barracuda Shaw, 1804; barracuda Cuvier, 1829; commersoni Cuvier, 1829; dussumieri Cuvier, 1829; agam Rüppell, 1835; affinis Rüppell, 1835; nuageuse Liénard, 1843; picuda Poey, 1866; snodgrassi Jenkins, 1901; and akerstromi Whitley, 1947. S. kadenar Montrouzier, 1857, and microps Marshall, 1953, are probably synonyms. Barracuda were collected off Miami, Florida, from Bimini, Bahamas, and specimens from the Danish Oceanographical Expeditions in the western Atlantic were used. Ontogenetic variation in proportional measurements was determined for 171 specimens from 5.5 to 1111 mm standard length. Keys for identification are presented for barracuda, gauchancho, picudilla, borealis, and sphyraena. Most males mature at two years and all mature by three years. Some females mature at three years, and all mature at four. The spawning season is from April until October off southern Florida. Spawning was not observed but probably occurs in the open ocean. The eggs were not identified from plankton tows. Postlarvae were taken far from shore and near the surface, over depths of 200 to 5200 meters. Age analyses were based upon the scale readings of 555 barracuda, back-calculated lengths from scale measurements, and upon modes in the length-frequency distributions of 2707 specimens from southern Florida. It attains 10 to 12 inches at the end of the first winter, and 18 to 22 inches at the end of its second. It reaches an age of at least 14 years. Maximum length is about 6 feet and a weight of more than 100 pounds. The young barracuda drifts inshore in spring, spends its first summer in shallow nursery areas, and moves offshore to somewhat deeper water in late fall. During the second summer it enters the mangrove habitat or the deeper weed beds. In its third year it enters the coral-reef habitat. The barracuda migrates seasonally along both coasts of Florida. Some individuals may drift out to sea. Young sometimes occur in loose aggregations, but the adults are solitary. Peck order was observed among individuals from 12 to 16 inches long which were confined in a tank. Young feed upon atherinids, gobiids, and clupeids. Tetraodontiform fishes, hemiramphids, and carangids were most commonly taken by the adults. A change from a shallow-water habitat to that of a reef existence is accompanied by a change in food habits. A summary of the 29 attacks reputedly made by barracuda on humans is presented and analyzed. Underwater experiences with barracuda are discussed in relation to factors which are favorable to an attack. Poisoning in humans who have eaten fresh barracuda is due to a toxin in the flesh and not from bacterial poisoning. In the western Atlantic, poisonings have occurred throughout the year. There seems to be no relation between the attainment of maturity or the spawning cycle and the poisonous nature of barracuda flesh. Some 58 per cent of the stomacs of adult barracuda contained fishes which are reputedly toxic, of which 20 per cent were tetraodontiform fishes. Evidence is presented for a food-chain origin of the toxin, and mechanisms are discussed for the transmission of the toxin from planktonic and benthic algae to barracuda by way of intermediate organisms. Variations in hydrographic and meteorological features are believed to results in distinct temporal and spatial variation in the toxicity of barracuda as well as other fishes"--p. 1-2.

Download or read book Spatial Ecology Of Great Barracuda Sphyraena Barracuda Rpara Around Buck Island Reef National Monument St Croix U S V I written by Sarah L. Becker and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine protected areas (MPAs) are increasing in popularity as a tool to manage fish stocks through conservation of entire habitats and fish assemblages. Quantifying the habitat use, site fidelity, and movement patterns of marine species is vital to this method of marine spatial planning. The success of these protected areas requires that sufficient habitat is guarded against fishing pressure. For large animals, which often have correspondingly large home range areas, protecting an entire home range can be logistically challenging. For MPAs to successfully protect large top predator species, it is important to understand what areas of a home range are especially important, such as breeding and feeding grounds. New technologies, such as acoustic telemetry, have made it possible to track marine animal movements at finer spatial and temporal scales than previously possible, better illuminating these spatial use patterns. This study focused on the movement patterns of great barracuda (n=35), an ecologically important top predator, around Buck Island Reef National Monument, a no-take MPA in St. Croix, U.S.V.I. managed by the National Park Service. As developing standardized methods for acoustic telemetry is still a work in progress, the first half of this study focuses on determining appropriate tools for generating home range size estimates for great barracuda and analyzing ecological parameters driving these results. The second half of this study focused on the use of network analysis to look at spatial divisions within individual home ranges and to compare individual to population level spatial patterns, as well as to generate a relative estimate of population density within the park. Barracuda within the park demonstrated high site fidelity to individual territories, but at the population level they consistently used all habitats within the array. Core use areas within home ranges were evenly distributed throughout all habitats monitored by the acoustic array, although movement corridors were detected along high rugosity reef structures. Greater population densities within the park indicate that density dependent behaviors may be influencing habitat use within the park, and suggest that barracuda are contributing high levels of top down pressure through predation within the park boundaries.
