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.

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.

This book is based on papers from the proceedings of a conference held at the Ettore Majorana Centre, Erice, Italy, provides an overview of the key developments in behavioural ecology. Four main areas of interest are covered the behavioural ecology of predator avoidance, foraging, resource defence and life histories and reproduction.
Download or read book Ecology of the Marine Fishes of Cuba written by Rodolfo Claro and published by Smithsonian Institution. This book was released on 2014-06-17 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Situated at the convergence of the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico, Cuba's coastal waters are home to one of the most diverse fish faunas in the Western Hemisphere. However, until now, information in English about Cuban marine fishes and their habitats has been limited. This comprehensive guide to the region's fishes fills that void. Originally published in Spanish in 1994, Ecology of the Marine Fishes of Cuba has been completely updated and revised for this English edition. The book collects and expands on the findings of more than 20 years of work by and international team of ichthyologists and marine biologists studying the coastal fishes and habitats of Cuba. In chapters arranged topically, the thirteen contributors detail the physical characteristics of the Cuban coast; document the physiology, behavior, reproduction, feeding patterns, and growth patterns of the region's fishes; and survey Cuba's fisheries management programs. The result is an unparalleled integration of English- and Spanish-language references on coastal fishes of the western Atlantic, complete with a comprehensive bibliography that constitutes a valuable reference in its own right. The extensive information presented here establishes an important foundation for comparisons of regional biological variations and demonstrates the need for proactive habitat and fishery management policies in the area.
Download or read book Bite Force in Two Top Predators the Great Barracuda Sphyraena Barracuda and Bull Shark Carcharhinus Leucas During Ontogeny written by Maria Laura Habegger and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Functional morphologists have extensively used measurements of performance to investigate the relationship among form, function and ecology through ontogeny. Among different measurements of performance bite force play a crucial role influencing fitness. Although, bite force has been thoroughly investigated among vertebrates, the majority of the studies on fishes have been concentrated only in small species. Consequently, this is the first study that compares the bite force performance in two large marine predators, the great barracuda (Sphyraena barracuda) and bull shark (Carcharhinus leucas). Values of posterior bite force in S. barracuda varied from 3 - 258 N for an ontogenetic series of 27 individuals (23 - 130 cm, TL). Bite force as well as the majority of the biomechanical variables that contribute to it scaled with isometry in S. barracuda. Values of posterior bite force in C. leucas varied from 170 - 5,914 N for and ontogenetic series of 16 individuals (73 - 285 cm, TL). Bite force at the most anterior bite point scaled with positive allometry as well as the majority of the subdivisions of the adductive musculature that greatly contribute to bite force. Bite force performance in this two species showed strong differences, where S. barracuda has one of the lowest relative values of bite force among fishes and C. leucas has one of the largest ones. Additionally, the scaling patterns for bite force and most of the biomechanical variables investigated in this study differed among these two species. These results suggest that predatory success may be acquired by different strategies, and that the same ecological role in a marine ecosystem may be reached by having different bite force performance.
Download or read book Biology and Ecology of Fishes written by James S. Diana and published by John Wiley & Sons. This book was released on 2023-06-08 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Ecology of Fishes Immerse yourself in the world of fish ecology with the newest edition of this essential introduction The study of fish ecology has traditionally proceeded along two tracks: the first is more basic, concerned with the anatomy, physiology and theoretical ecology of fish, and the second is more practical, concerning itself with fish populations, management, and habitats. Many fish researchers have come to view this distinction as artificial, and to develop a new study of fish that combines both tracks in a single holistic approach. It has never been more critical for introductory textbooks to represent this combined study in order to prepare the next generation of fish biologists and fishery scientists. Biology and Ecology of Fishes meets this need with a textbook that incorporates both biology and population management. Beginning with a general introduction to aquatic life and ecosystems, this book covers anatomical, environmental, and ethological topics to give a thoroughly rounded view of its subject, promising to serve as the fundamental introduction to multidisciplinary fish studies. Readers of the third edition of Biology and Ecology of Fishes will also find: Detailed coverage of subjects including growth and bioenergetics, feeding and predation, mortality and recruitment and more Increased attention to stressors of fish populations and communities New and revised chapters that introduce quantitative methods and present emerging issues facing fish populations and communities Biology and Ecology of Fishes is a useful overview for advanced undergraduate and graduate students studying fish ecology or fishery biology, as well as a reference for researchers and professionals in fish ecology, fish population management, and related fields.

Download or read book Behavioral Ecology of Coral Reef Fishes at Spawning Aggregation Sites written by Gorka Sancho and published by . This book was released on 1998 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis is an extensive investigation of the behavioral and ecological relationships between spawning reef fishes, their predators, and various environmental parameters at spawning aggregation sites. Underwater observations of spawning activities by eleven reef fish species and the hunting behaviors of both piscivorous and planktivorous predators were made at Johnston Atoll (Central Pacific). The spawning of reef fishes was typically correlated with local changes in current direction and predatory risks in daytime-spawning species, showing responses designed to reduce the mortality of propagules and adults. Dusk-spawning species generally did not respond to changes in flow direction or predator abundance. Piscivores were most active at spawning sites during the daytime hours, when spawning prey fish were most abundant, but showed low activity at dusk, the period of highest prey diversity. Alternate hunting behaviors (midwater or ambush attacks) were used by piscivores when feeding on spawning fishes, and resulted in different capture success rates. The difference in heights of spawning ascents by two trunkfish species was interpreted to be the result of intraspecific competition among males, and could not be explained by interspecific differences in susceptibility to predation, estimated as a function' of the specific toxicity of both species. ."--Stinet
