![]() ![]() Phenotypic variation of early life history stages influences all aspects of fish biology from taxonomic definitions, to the fitness and fate of individuals, and to population dynamics. This session invites contributions who seek a better understand how early life stages acquire and utilize food, deal with variations in nutrient availability, and respond to nutrients later in life following “programming” by diets consumed during early ages.Īssessing and Evaluating Phenotypic Variation in Fish Early Life History Stages: Field Studies, Experiments, and ModelingĬonveners: Klaus Huebert, University of Maryland Center for Environmental Science, Horn Point Laboratory ( ), Tom Miller, University of Maryland Center for Environmental Science, Chesapeake Biological Laboratory ( ), and Chris Chambers, NOAA Northeast Fisheries Science Center ( ) It is also imperative that we understand how the smallest changes in nutrient availability or timing can affect the physiology of fish larvae with effects possibly lasting into adulthood. Webb, University of Texas Marine Science Institute ( )īeginning with maternally deposited nutrients and ending with metamorphosis into juvenile forms, nutrition and feeding of early life stages are critical to successful growth and recruitment of all fishes. Nutrition and Feeding of Fish Early Life StagesĬonvener: Kenneth A. This session will provide an overview of abilities of larval fishes to face the physical and chemical challenges imposed by an often highly variable aquatic environment. Marta animal de alaska series#A series of key physiological processes will be highlighted, including development and plasticity regulation/osmoregulation, transport and gas exchange genomic and DNA integrity immuno/pathophysiology, respiration and homeostasis sensory physiology and neuromechanisms and control and defense of organisms. ![]() The purpose of this session is to bring together expertise with foundational knowledge in the comparative and integrative physiology of larval fishes. Methods and strategies of evaluation have to be constantly rethought and reinvented. Study of physiological processes in larval fishes can be highly challenging due to their extremely small sizes and often an extremely rapid developmental progression. Furthermore, fish early life stages are now recognized as indispensable components in various world regulatory settings, as alternative animal models for understanding vertebrate development, and as effective for assessment of pharmaceutical substances and/or environmental conditions. Failure in development or homeostasis during these critical stages could lead to detrimental consequences for fish welfare/fitness in later stages. The physiology of adult fishes has been studied for centuries, but investigations of physiological processes in larval stages have only recently been a focus of study, even though these biological processes are crucial to our overall understanding of evolutionary history. Burggren, University of North Texas ( ) and Prescilla Perrichon, University of North Texas ( ) This session welcomes experimental, field, and modeling studies that explore the broad spectrum of potential responses to, and consequences of multiple stressors impacting larval fish ecology, physiology, and adaptive capacity.Ĭomplexity and Performance Change During Physiological Development of Larval FishesĬonveners: Warren W. Here we invite contributions that address this knowledge gap. ![]() While the concurrent nature of many of these stressors has been robustly documented, research on the combined effects of multiple stressors on important life history traits and their implications for future fish stock productivity and resiliency is still in its infancy. The Effects of Climate Change on Marine Fish Early Life Stages: Which Stressors are Most Important and How Do They Interact?Ĭonveners: Hannes Baumann, University of Connecticut-Avery Point ( ) and Marta Moyano, University of Hamburg ( )Įarly life stages of fishes are particularly susceptible to the suite of ongoing, simultaneous changes in marine and freshwater environments, from rising temperatures and increasing acidification, to hypoxia, chemical pollution, and habitat alteration.
