Alternative Proteins for Fish Diets: Implications beyond Growth

Animals, Journal Year: 2022, Volume and Issue: 12(9), P. 1211 - 1211

Published: May 7, 2022

Aquaculture has been challenged to find alternative ingredients develop innovative feed formulations that foster a sustainable future growth. Given the most recent trends in fish formulation on use of protein sources decrease dependency fishmeal, it is fundamental evaluate implications this new paradigm for health and welfare. This work intends comprehensively review impacts novel dietary gut microbiota health, stress immune responses, disease resistance, antioxidant capacity. The research results indicate sources, such as terrestrial plant proteins, rendered animal by-products, insect meals, micro- macroalgae, single cell proteins (e.g., yeasts), may negatively impact thus affecting responses. Nevertheless, some insects algae have functional properties exert an immunostimulatory activity. Further effects beyond growth, clearly needed. information gathered here utmost importance, order diets guarantee production healthy with high quality standards optimised welfare conditions, contributing growth aquaculture industry.

Toxic Effects of Cadmium on Fish

Toxics, Journal Year: 2022, Volume and Issue: 10(10), P. 622 - 622

Published: Oct. 19, 2022

Large amounts of enriched cadmium (Cd) in the environment seriously threatens healthy and sustainable development aquaculture industry greatly restricts food processing industry. Studying distribution toxic effects Cd fish, as well possible on human body, is very significant. A large number studies have shown that accumulation fish are biologically specific, cause tissue differences, damage integrity structure function, antioxidant defense system, reproductive regulation immune system. The physiological, biochemical, enzyme, molecular, gene expression levels change with different concentrations times exposure, these changes closely related to target sites action tissues fish. Therefore, occur multiple tissues, systems, levels.

Effects of Pollution on Fish Behavior, Personality, and Cognition: Some Research Perspectives

Frontiers in Ecology and Evolution, Journal Year: 2020, Volume and Issue: 8

Published: April 7, 2020

Pollutants, and more generally, environmental stressors, are a neglected source of behavioral cognitive variations in wild populations. Based on recent literature fish, we highlight four interesting research perspectives to better understand the effects pollutants links between behavior, cognition fitness. First, (1) review neurotoxic fish personality cognition. These could turn affect level exposure pollutants, potentially generating feedback loops that may amplify Second, propose (2) should be studied multistress context, i.e. realistic conditions combination with other because some stressors Third (3), existing studies show physiological traits often linked syndromes. Pollutants lead syndrome disruption, which evolutionary trajectories exposed Future thus focus complex consequences trajectories. Fourth, (4) chronic pollution local (mal)adaptation, result into high intraspecific variability sensitivity among In addition, responses constrain, or constrained by stressors. We encourage future use integrative approaches bridge gap ecotoxicology, ecology framework improve our ability predict anthropogenic wildlife.

Enrichment accepted as essential requirement meeting behavioural needs improving welfare many animal species, but in general, minimal. Some those involved use suggest there a ‘lack evidence’ that enrichment has benefits this or cite belief do not ‘need’ Concerns are also sometimes raised practical challenges providing enrichments, they may impact science being undertaken.

Application of enzymes as a feed additive in aquaculture

Marine Life Science & Technology, Journal Year: 2022, Volume and Issue: 4(2), P. 208 - 221

Published: April 19, 2022

Modern aquaculture must be sustainable in terms of energy consumption, raw materials used, and environmental impact, so alternatives are needed to replace fish feed with other materials. Enzyme use the agri-food industry is based on their efficiency, safety, protection environment, which aligns requirements a resource-saving production system. supplementation can improve digestibility absorption both plant- animal-derived ingredients, increasing growth parameters aquacultural animals. Herein we summarized recent literature that reported digestive enzymes (amylases, lipases, proteases, cellulases, hemicellulases) non-digestive (phytases, glucose oxidase, lysozyme) feed. In addition, analyzed how critical steps pelleting process, including microencapsulation immobilization, interfere enzyme activity final product.The online version contains supplementary material available at 10.1007/s42995-022-00128-z.

Physiological and behavioural strategies of aquatic animals living in fluctuating environments

Journal of Experimental Biology, Journal Year: 2022, Volume and Issue: 225(9)

Published: May 1, 2022

ABSTRACT Shallow or near-shore environments, such as ponds, estuaries and intertidal zones, are among the most physiologically challenging of all aquatic settings. Animals inhabiting these environments experience conditions that fluctuate markedly over relatively short temporal spatial scales. Living in habitats requires ability to tolerate physiological disturbances incurred by environmental fluctuations. This tolerance is achieved through a suite behavioural responses allow animals maintain homeostasis, including dynamically modulate their physiology reversible phenotypic plasticity. However, maintaining plasticity adjust some stresses dynamic environment may trade off with capacity deal other stressors. paper will explore studies on select fishes invertebrates exposed fluctuations dissolved oxygen, salinity pH. We assess mechanisms species employ achieve focus responses, consider resulting trade-offs function. Finally, we discuss additional factors influence organismal fluctuating presence multiple stressors, parasites. echo recent calls from experimental biologists life naturally not only because they interesting own right but also can reveal be crucial for living increasing instability consequence climate change.
