Cambridge Prisms Water, Journal Year: 2024, Volume and Issue: 2

Published: Jan. 1, 2024

Abstract The aquaculture industry requires good water quality for its successful operation but produces wastes that can cause environmental deterioration and pose high risks to the sector. Adequate waste treatment recycling are necessary make a sustainable profitable contribute circular economy. Polluted sources, excess feeding, overstocking, use of antibiotics/chemicals harmful algal blooms major causes low production in systems. Discharges untreated would have serious impacts on receiving bodies, eventually itself. Possible solutions include technological innovations environmentally friendly systems, efficient processes management improved legislation governance. Environmentally feasible technologies such as system, integrated multi-trophic aquaponics including features viable options schemes. Best practices integrating advanced technologies, supported by automation sensors, modeling artificial intelligence-internet things environment, stable value chain. In general, low-cost impact reduction through governance crucial achieving sustainability natural management.

Assessing the vulnerability of food supply chains to climate change-induced disruptions

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 920, P. 171047 - 171047

Published: Feb. 17, 2024

Climate change is one of the most significant challenges worldwide. There strong evidence from research that climate will impact several food chain-related elements such as agricultural output, incomes, prices, access, quality, and safety. This scoping review seeks to outline state knowledge supply chain's vulnerability identify existing literature may guide future research, policy, decision-making aimed at enhancing resilience chain. A total 1526 publications were identified using SCOPUS database, which 67 selected for present study. The assessment methods well adaptation measures have been employed alleviate in chain discussed. results revealed a growing number providing weakening due extreme weather events. Our demonstrated need broaden into entire various forms climatic variability because studies concentrated on relationships between fluctuations (especially rainfall, temperatures, drought) production. lack about effects underlying socio-economic consequences could result underperformance or failure

Published: Jan. 27, 2023

This work aims to determine the impact of dietary supplementation polysaccharide, extracted from brown seaweeds Sargassum dentifolium on growth indices, feed utilization, biochemical compositions, microbial abundance, expressions and immunity-related genes, stress genes Pacific Whiteleg shrimp Litopenaeus vannamei. A total 360 post-larvae L. vannamei were randomly distributed into a 12-glass aquarium (40 L each) at stocking density 30 with an initial weight (0.0017 ± 0.001 g). During 90-day experiment trial, all larvae fed their respective diets 10% body weight, three times day. Three experimental prepared different seaweed polysaccharide (SWP) levels. The basal control diet had no level (SWP0), while SWP1, SWP2, SWP3 contained polysaccharides concentrations 1, 2, 3 g kg-1 diet, respectively. Diets supplemented levels showed significant improvements in gain survival rate, compared diet. Whole-body composition abundance (the count heterotrophic bacteria Vibrio spp.) differences among polysaccharide-treated control. At end feeding experiment, enhanced expression growth-related (Insulin-like factors (IGF-I, IGF-II), immune-related (β -Glucan-binding protein (β-Bgp), Prophenoloxidase (ProPO), Lysozyme (Lys), Crustin), (Superoxide dismutase (SOD) Glutathione peroxidase (GPx) muscle tissue However, current study concluded that inclusion rate 2 as additive administration both vannamei, incorporation reduces pathogenic microbes enhances growth-, immunity- stress-related gene

How does the climate change effect on hydropower potential, freshwater fisheries, and hydrological response of snow on water availability?

Applied Water Science, Journal Year: 2024, Volume and Issue: 14(4)

Published: March 7, 2024

Abstract Globally there is already a lot of pressure on water resources because climate change, economic development, as well an increasing global populace. Many rivers originate in the mountains, where snowfall fluctuations and climate’s inherent unpredictability affect hydrological processes. Climate change sensitivity has been recognized recent years would hydropower, such humidity, cloudiness, precipitation, that are considered; warming emerges one most important contributors to change. The Yangtze River supports rich biodiversity provides ecosystem services for human survival development. In addition, changes, particularly short-term long-term precipitation temperature fluctuations, influence snow regime development river flow response at basin sub-basin scales. More precise this review focused understand hydropower potential, freshwater fisheries, dynamics snow-dominated basins.

Fish Responses to Alternative Feeding Ingredients under Abiotic Chronic Stress

Animals, Journal Year: 2024, Volume and Issue: 14(5), P. 765 - 765

Published: Feb. 29, 2024

Aquaculture has become one of the most attractive food production activities as it provides high-quality protein for growing human population. However, abiotic chronic stress fish in intensive farming leads to a detrimental condition that affects their health and somatic growth, comprising productive performance. This work aims comprehensively review impact alternative novel dietary sources on metabolism, antioxidative capacity under environmental/abiotic stressors. The documental research indicates ingredients from rendered animal by-products, insects, bacteria single-cell proteins, fungal organisms (e.g., yeast, filamentous fungus, mushrooms) benefit A set responses allows health, survival remain unaffected by feeding with during environmental stress. Those stimulate enzymes such catalase, glutathione peroxidase, selenoproteins counteract ROS effects. In addition, humoral immune system promotes immunoglobulin (IgM) cortisol plasmatic reduction. Further investigation must be carried out establish specific effect species. Additionally, mixture pre-treatment hydrolysates, solid fermentations, metabolite extraction potentialize beneficial effects diets chronically stressed fish.
