This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Otoliths are dense calcium carbonate structures within the cranium, which put pressure on cilia and stimulate sensory hair cells, enabling a fish to hear. The crystalline composition of otoliths is often in the dense calcium carbonate form of aragonite. Aragonite otoliths can shift to the less dense polymorph, vaterite, which becomes irregularly shaped and decreases the fish's ability to hear. Previous studies found that vateritic otoliths are more likely to occur in recirculating aquacultured systems (RAS). Many studies have suggested possible factors that cause a change to the crystalline structure of the otolith, which include fast growth, temperature, pH, and genetic predisposition. However, evidence suggests that increased levels of dissolved carbon dioxide (CO2) may be a causative agent in the shift of an otolith's composition from aragonite to vaterite. RAS are utilized to raise as many fish as feasible in tanks which leads to high stocking densities. Such densely populated tanks are susceptible to increased levels of CO2 due to metabolic processes. Therefore, a physiological study was conducted to test the effects of CO2 in rainbow trout (Oncorhynchus mykiss). CO2 was dispersed through airflow meters to three tanks that received 0, 15, or 30 mg/L of additional CO2. Weight (g) and length (mm) of fish were measured every two weeks to determine whether CO2 exposure caused adverse effects on growth. Sagittal otolith samples were taken at the start of the experiment (n=14) and every 4 weeks (n=5) from each tank over the course of the 8-week experiment. A micro Raman spectrometer (Reshinaw) equipped with a 785 nm excitation laser was used to determine the crystalline structure of the otoliths. An ANOVA was used to analyze vaterite prevalence and severity at the initial, 4 weeks, and 8 weeks sampling, followed by a Tukey HSD. No significant differences were observed for the prevalence and severity of vaterite among CO2 treatments. There also were no significant differences due to exposure to CO2 on growth (length and weight) among treatments. Ultimately, further rigorous testing is required to assess elevated CO2 as a potential causative agent for vaterite otoliths in RAS.

Book excerpt: Fish Physiology, Volume 38 in this ongoing series, examines how the inherent potential of fish to express traits of economic value can be realized through aquaculture. Topics covered include the regulation of the reproductive cycle of captive fish, shifting carnivorous fish towards plant-based diets, defining the challenges, opportunities and optimal conditions for growth under intensive culture (including in Recirculating Aquaculture Systems), enhancing immune function and fish health during culture, identifying and managing maladaptive physiological responses to aquaculture stressors, establishing welfare guidelines for farmed fish, phenotypic and physiological responses to genetic modification, Zebrafish as a research tool, and the aquaculture of air-breathing fish. Contains contributions from an international board of authors, each with decades of aquaculture expertise Provides the most up-to-date information on the fundamental role that physiology plays in optimizing fish performance in aquaculture Provides the latest release in the Fish Physiology series that tackles how the manipulation of biological processes can be used to maximize the expression of beneficial production traits in fish aquaculture
Download or read book Effects of Constant Temperature and Thermal Shifts on Survival Morphology and Oxygen Consumption in Rainbow Trout Oncorhynchus Mykiss Embryos written by Christopher L. Melendez and published by . This book was released on 2019 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental temperature is a crucial environmental factor that influences many physiological functions in fishes. Rainbow trout (Oncorhynchus mykiss) are a native anadromous species that inhabit a variety of freshwater rivers and lakes and are widely distributed throughout the western portion of the United States. Resident rainbow trout populations occupy interior freshwater environments for the entirety of life. Interior bodies of water are most susceptible to changes in environmental temperatures. Therefore, resident rainbow trout are likely to be impacted by variable and rising temperatures, particularly during embryonic development. Understanding temperature effects during development is likely to provide insight into the overall thermal biology of a species and its persistence in a changing climate. To assess the effect of temperature on development of rainbow trout, we examined phenotypes of hatchery embryos reared in various incubation temperatures (5°C, 10°C, 15°C and 17.5°C). To identify the presence of embryonic developmental plasticity within developmental time points, embryos incubated in 5°C were exposed to either 10°C, 15°C or 17.5°C during gastrulation, organogenesis, system integration or growth windows and a 3-dimensional critical window model was applied. An increase in constant incubation temperature increased oxygen consumption rate (V̇O2), and decreased hatchling survival, mass, yolk size, body length and time to 50% hatch. Thermally shifting embryos into increased temperature during distinct windows of development also reduced survival at hatch, and this was most evident following exposure during organogenesis, which may signify the presence of a critical window for this trait. Likewise, thermally shifting embryos into increased temperature resulted in smaller hatchlings. Although there was an initial increase in V̇ O2 in response to temperature, experiencing thermal shifts during development had no persistent effect on V̇ O2 when measured at hatch at 5°C compared to 5°C constant embryos. Collectively, these results suggest that survival and morphological traits of rainbow trout embryos are most sensitive to increased temperature during organogenesis and system integration, but increased temperature does not appear to have a long-term effect on energy use. Environmental temperature plays a fundamental role in developing aquatic vertebrates. Thus, critical window studies such this performed across species will eventually allow for the identification of commonalities in plasticity between different species in response to variables such as temperature.

This book was released on 2015 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the western U.S., the Pacific salmonids (Oncorhynchus spp.) are of significant cultural, socioeconomic and ecological importance. However, despite decades of conservation efforts, their continued decline remains a great concern. Two critical factors impacting the sustainability of salmon and steelhead populations in the Pacific Northwest include genetic introgression of captive-reared hatchery fish and climate warming. Although salmonid hatcheries have been recognized as having a valuable role in restoring wild stocks, gene flow from domesticated hatchery fish into wild populations presents obstacles for conservation. Additionally, climate change is predicted to continue to increase stream temperatures in the Pacific Northwest, which is particularly hazardous for cold-water dependent Oncorhynchus spp., as their physiology, behavior, and distribution are crucially linked to temperature. Here these factors were investigated using clonal lines of rainbow trout (Oncorhynchus mykiss) by evaluating phenotypic responses to these two factors in the context of developing management protocols to facilitate their sustained existence.

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.
