Download or read book Fish Pheromones and Related Cues written by P. W. Sorensen and published by John Wiley & Sons. This book was released on 2015-03-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pheromones are chemical cues that pass between members of the same species that convey specific, adaptive information. These cues, and related chemicals whose function are less well defined, are especially important to fishes because of their aquatic environments and complex behaviors. Pheromones are also of increasing interest in both basic and applied aspects of fish biology because they can be used to manipulate fish behavior and may explain phenomena such as fishery collapse. Fish Pheromones and Related Cues provides a timely synthesis of this growing body of research in freshwater and marine species and explores everything from how these chemical signals evolved, are produced, released and then processed, and finally to potential applications in fish culture and conservation. Fish Pheromones and Related Cues opens with a useful overview on the theory of chemical communication and definitions. Chapters then progress by examining the biological importance of pheromones in inter- and intra-species communication, the role these chemical cues play in a variety biological functions from reproduction to predation, and then how they evolved and are detected and recognized by fish nervous systems. Final chapters provide valuable insight into how pheromones can be measured, how pheromonal disruption can explain effects of environmental pollution, and lastly how they pheromones are being applied in real-world efforts to culture fish species and to conserve our wild populations and control invasive species. With far-reaching economic, evolutionary and ecological implications, Fish Pheromones and Related Cues will be an essential volume for anyone working in the fields of chemical communication, fish biology, fisheries science, aquatic conservation, ecology, invasive species control, and aquaculture

Download or read book Aquaculture and Behavior written by Felicity Huntingford and published by John Wiley & Sons. This book was released on 2012-02-13 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern aquaculture is faced with a number of challenges, including public concern about environmental impacts and the welfare of farmed fish. A fundamental understanding of fish biology is central to finding ways to meet these challenges and is also essential for maintaining the industry's sustainability. Furthermore, the behaviour of fish under culture situations has long been ignored despite heavy commercial losses that can result from fish stressed and hence disease-prone, due to bad husbandry techniques. This important book summarises the current understanding of the behavioural biology of farmed species and illustrates how this can be applied to improve aquaculture practice. Informative and engaging, Aquaculture & Behavior brings the reader up-to-date with major issues pertaining to aquaculture. Everyone from fish farmers to upper level students will find this book a valuable and practical resource. Libraries in universities and research establishments where animal behavior, aquaculture, veterinary and biological sciences are studied and taught should have copies of this work on their shelves.

Download or read book Susceptibility of Juvenile Fishes to Environmental Change written by Brittany Elizabeth Davis and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rockfish that inhabit seagrass beds may be particularly robust to environmental perturbation with an enhanced ability to compensate for alterations in PCO2 and DO compared to species living in more stable environments; however, studies on fishes in seagrass habitats are often overlooked compared to kelp forests or deep ocean waters when examining the effects of GCC conditions. I exposed rockfish to two PCO2 conditions (ambient [600] and high [1600 μatm PCO2]) across two levels of DO (normoxic [8.0] and hypoxic [4.5 mg l-1]) and measured physiological costs (cellular metabolism), behavioral responses (activity, exploration, and anti-predator responses), and predator-prey interactions (survival from cabezon [Scorpaenichthys marmoratus], a common predator of rockfish). I found evidence of short-term elevations in cellular metabolism, alterations in behavior, and susceptibility to predation in juvenile rockfish after acute acclimation to high PCO2 and hypoxic conditions. However, after 3-weeks of exposures, physiological and behavioral alterations were restored suggesting that rockfish likely possess plasticity in mechanisms to defend against wide changes in PCO2 and oxygen conditions. Our findings indicate local adaptation and life-history strategies are a critical factor in understanding species responses to future GCC conditions and whether a species is likely to be robust or sensitive. In chapter four, I investigated how GCC-correlated drought periods in California may influence fishes in the San Francisco Estuary-Sacramento/San Joaquin Bay-Delta rivers (hereafter Bay-Delta). GCC and drought periods may alter the Bay-Delta with increased in water temperature, sea level rise and reduced snowpack with less water outflow, both of which lead to saltwater intrusion and increased salinity regimes in the Delta. Already, a pelagic fish Delta Smelt (Hypomesus transpacificus), endemic to the Bay-Delta has precipitously declined, potentially to near extinction; however, it remains unclear how multiple drought stressors of high temperature and salinity interact to affect fish survival, and the influence Delta Smelt populations. Because the Bay-Delta is one of the most highly invaded ecosystems in the world, I also wanted to explore the effects of multiple drought stressors on non-native competitors and predators that influence Delta Smelt populations. Therefore, in this study I assessed the influence of elevated temperature (20°C) and salinity (12 ppt) as co-occurring stressors on the physiological performance of three Delta fishes: juvenile native, endangered Delta Smelt, and juvenile non-native Mississippi Silverside (Menidia beryllina) and Largemouth Bass (Micropterus salmoides). I determined species-specific vulnerability (i.e. tolerance) to elevated salinity and temperature, and characterized if the series in which stressors where experienced (e.g. initial warming, subsequent increased salinity, and vice-versa) affected the physiological tolerance of fishes. I found that each species had the capacity to tolerate a series of co-occurring stressors, and thermal history, not salinity, determined upper thermal tolerance. As expected, non-native fish were more thermally tolerant than native Delta Smelt; however, species-specific plasticity of upper tolerance was evident. Delta Smelt and Silversides rapidly reached new thermal tolerance baselines following 2-4 days of acclimation to 20°C, whereas Largemouth Bass upper tolerance was still increasing after 7 days of acclimation. Estimated thermal safety margins, that is, the buffer (i.e. temperature difference) between upper thermal tolerance and maximum habitat temperatures indicated, Delta Smelt have the narrowest margin for performance within Bay-Delta habitats, and with projected 2-3°C increases in temperature from GCC some thermal safety margins may become negative influencing the overall survival of the population. Since thermal history, and not salinity underlined physiological changes in California’s critically endangered Delta Smelt (H. transpacificus), the last chapter (five) focused exclusively on the effects of warming (a single stressor) on Delta Smelt behavioral responses and susceptibility to predation. The effects of temperature on individual and group movement behavior in prey fish can affect ecological interactions such as competition and predation. Therefore, in addition to understanding the effects of warming on physiology, it is important to understand how behavioral responses to warming may influence populations. We tested how high temperature experienced as constant (21°C) or fluctuated warming (as in a natural tidal cycle, daily 17-21°C) affects group structure of Delta Smelt shoals, anti-predator responses (i.e. conspecific alarm cue or predator-borne cue) and predation susceptibility from Largemouth Bass. This study quantified for the first time the free-swimming characteristics and group structure of Delta Smelt. In general, Delta Smelt did demonstrate shoaling behavior, remaining on average 2 body lengths from their nearest neighbor. There were significant effects of constant warming on both individual and structural behaviors; however, if warming was fluctuated in a manner closely mimicking that of the natural tidal cycle, Delta Smelt movement was not affected compared to the control group (held at ambient temperature, 17°C). Similarly, Delta Smelt’s response to conspecific alarm cue, predator cues, and a real-predation threat were also dependent on the type of warming treatment, such that significant mal-adaptive behaviors and increased predation mortality were exhibited under constant warming, but not fluctuated warming. While this last study proves important information about shoaling behaviors of Delta Smelt under warming, more importantly, from an experimental perspective, future studies should take care to match temperature treatments closer to real-world daily fluctuations when and where possible.

Download or read book Handbook of Social Interactions in the 21st Century written by Anne T. Heatherton and published by . This book was released on 2009 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social interaction is a dynamic, changing sequence of social actions between individuals (or groups) who modify their actions and reactions according to those of their interaction partner(s). In other words, they are events in which people attach meaning to a situation, interpret what others are meaning, and respond accordingly. Social interactions can be differentiated into: Accidental (also known as social contact) - not planned and likely not repeated. For example, asking a stranger for directions or shopkeeper for product availability. Repeated - not planned, bound to happen from time to time. For example, accidentally meeting a neighbour when walking on your street; Regular - not planned, but very common, likely to raise questions when missed. Meeting a doorman or a security guard every workday in your workplace, dining every day in the same restaurant, etc. Regulated - planned and regulated by customs or law, will definitely raise questions when missed. Interaction in a workplace (coming to work, staff meetings, playing a game, etc.), family, etc. In sociological hierarchy, social interaction is more advanced than behaviour, action, social behaviour, social action and social contact, and is in turn followed by more advanced concept of social relation. In other words, social interactions, which consist of social actions, form the basis for social relations. This handbook presents the latest international research in the field.

Download or read book Cephalopod Behaviour written by Roger T. Hanlon and published by Cambridge University Press. This book was released on 2018-03-22 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: With their large brains, elaborate sense organs and complex behaviour, cephalopods are among the world's most highly evolved invertebrates. This second edition summarises the wealth of exciting new research data stemming from over five hundred papers published since the first volume appeared. It adopts a comparative approach to causation, function, development and evolution as it explores cephalopod behaviour in natural habitats and the laboratory. Extensive colour and black-and-white photography illustrates various aspects of cephalopod behaviour to complement the scientific analysis. Covering the major octopus, squid and cuttlefish species, as well as the shelled Nautilus, this is an essential resource for undergraduate and advanced students of animal behaviour, as well as researchers new to cephalopods, in fields such as neuroscience and conservation biology. By highlighting the gaps in current knowledge, the text looks to inform and to stimulate further study of these enigmatic and beautiful animals.

Download or read book The Physiology of Developing Fish Viviparity and Posthatching Juveniles written by and published by Academic Press. This book was released on 1988-04-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE: Dramatic changes occur in the physiology of most animals during their development. Among the vertebrates, birds are entirely oviparous, live for variable periods in a cleidoic egg, and show fundamental alterations in excretion, nutrition, and respiration at the time of hatching. In contrast, the eutherian mammals are all viviparous, depend on the maternal circulation and a specialized placenta to provide food, exchange gases, and discharge wastes. The physiology of both mother and fetus is highly specialized during gestation and changes fundamentally at the time of birth. Fishes exemplify both the oviparous and the viviparous modes of development, with some examples that are intermediate between the two. In these two volumes, selected reviews of many, but not all, aspects of development are presented. The chapters in Part A relate to the physiology of eggs and larvae; those in Part B concern viviparity and the physiology of posthatching juvenile fishes.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about the behaviour of teleosts, a well-defined, highly successful, taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are weH over 22000 living species of teleosts, including nearly all those of importance in com mercial fisheries and aquaculture. Teleosts are represented injust about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour is the primary interface between these effective survival machines and their environment: behavioural plasticity is one of the keys to their success. The study of animal behaviour has undergone revolutionary changes in the past decade under the dual impact of behavioural ecology and sociobiology. The modern body of theory provides quantitatively testable and experi mentaHy accessible hypotheses. Much current work in animal behaviour has concentrated on birds and mammals, animals with ostensibly more complex structure, physiology and behavioural capacity, but there is a growing body of information about the behaviour of fishes. There is now increasing awareness that the same ecological and evolutionary rules govern teleost fish, and that their behaviour is not just a simplified version of that seen in birds and mammals. The details of fish behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment.

Download or read book Fish Welfare written by Edward J. Branson and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.
