The effect of environmental stressors on growth in fish and its endocrine control

Frontiers in Endocrinology, Journal Year: 2023, Volume and Issue: 14

Published: March 30, 2023

Fish body growth is a trait of major importance for individual survival and reproduction. It has implications in population, ecology, evolution. Somatic controlled by the GH/IGF endocrine axis influenced nutrition, feeding, reproductive-regulating hormones as well abiotic factors such temperature, oxygen levels, salinity. Global climate change anthropogenic pollutants will modify environmental conditions affecting directly or indirectly fish performance. In present review, we offer an overview somatic its interplay with feeding regulatory summarize effects global warming main on these axes.

The effects of environmental changes on the endocrine regulation of feeding in fishes

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1898)

Published: Feb. 5, 2024

Fishes are exposed to natural and anthropogenic changes in their environment, which can have major effects on behaviour physiology, including feeding behaviour, food intake digestive processes. These alterations owing the direct action of environmental physico-chemical parameters (i.e. temperature, pH, turbidity) physiology but also be a consequence variations availability. Food is ultimately regulated by centres brain, receive process information from endocrine signals both brain peripheral tissues such as gastrointestinal tract. stimulate or inhibit intake, interact with each other maintain energy homeostasis. Changes conditions might change habits rates, thus affecting levels stores, expression appetite regulators. This review provides an overview how availability could affect these networks fishes. article part theme issue ‘Endocrine responses variation: conceptual approaches recent developments’.

Interactive Effect of Dietary Gamma-Aminobutyric Acid (GABA) and Water Temperature on Growth Performance, Blood Plasma Indices, Heat Shock Proteins and GABAergic Gene Expression in Juvenile Olive Flounder Paralichthys olivaceus

Metabolites, Journal Year: 2023, Volume and Issue: 13(5), P. 619 - 619

Gamma-aminobutyric acid (GABA) is an important inhibitory neurotransmitter in the central nervous system of living organisms and has ability to reduce magnitude stress humans animals. In this study, we evaluated supplemental effects GABA on normal high water temperature based growth, blood plasma composition as well heat shock proteins GABA-related gene expression juvenile olive flounder. For this, a 2 × factorial design experiment was employed investigate dietary at 0 mg/kg diet (GABA0 diet) 200 (GABA200 temperatures 20 ± 1 °C (normal temperature) 27 (high for 28 days. A total 180 fish with average initial weight 40.1 0.4 g (mean SD) were distributed into 12 tanks, which, each tank contained 15 4 treatment groups triplicate. At end feeding trial, results demonstrated that both had significant growth performance fish.

Impact of climate change on the distribution of Trachurus japonicus in the Northern South China Sea

Ecological Indicators, Journal Year: 2024, Volume and Issue: 160, P. 111758 - 111758

Published: Feb. 23, 2024

Understanding the impact of climate change on distribution marine species is vital importance for sustainable development fisheries. In this study, an ensemble model employed to predict potential Japanese jack mackerel (Trachurus japonicus) in Northern South China Sea (NSCS) under current conditions and three future scenarios (IPCC Representative Concentration Pathways RCP126, RCP245, RCP585). The incorporates environmental variables including sea surface salinity (SSS), height above geoid (SSH), temperature (SST), ocean mixed layer thickness (MLD), distance from land (DFL). Notably, SST SSH are found be most influential factors defining habitat T. japonicus. Model predictions reveal that suitable habitats japonicus primarily located offshore area west Pearl River estuary, especially waters with depths less than 100 m NSCS. Beibu Gulf emerges as a prominent species. However, projections indicate significant reduction areas high probability occurrence, particularly emissions. This observed NSCS at ranging 40 m, while northwestern coastal regions projected witness increase habitats. rate contraction expected surpass expansion, estimated 16.93 % 29.27 decrease by 2091–2100.These findings offer fundamental insights into how impacts provide valuable guidance resource utilization.

Amyloodiniosis in aquaculture: A review

Reviews in Aquaculture, Journal Year: 2023, Volume and Issue: 16(3), P. 1042 - 1068

Published: Dec. 13, 2023

Abstract Fish ectoparasites are one of the pathogens groups that pose great concern to aquaculture industry. The dinoflagellate Amyloodinium ocellatum is responsible for amyloodiniosis, a parasitological disease with strong economic impact in temperate and warm water aquaculture, mainly earthen pond semi‐intensive systems. Amyloodiniosis represents most important bottlenecks and, predictable expansion area influence this parasite higher latitudes due global warming it might also be threat other species not yet parasitized by A. . This review made compilation existing knowledge about associated it. It was noticed that, except from life cycle characterisation, detection methods, histopathological analysis, treatments, there still lot areas need further investment research. Areas like parasite–host interactions, epidemiological models, taxonomy, host physiological responses parasitism, genome sequencing, amongst others, can contribute better understanding disease. These proposed approaches routes investigation will enhance more standardised knowledge, creating opportunity amyloodiniosis impacts on fish contributing development new tools against , may reduce mortality production outbreaks.
