Abstract A marked increase in food production is necessary if the World Health Assembly goal of ending world hunger and malnutrition in all its forms by 2030 is to be achieved. To this end, aquaculture plays a major role, but it could play an even more prominent role at least in some areas, especially Africa. There is a need to further develop aquaculture because harvesting from natural populations

Abstract This study aims to explore the shrimp export competitiveness of Bangladesh, China, India, Indonesia, Thailand, and Vietnam time spanning from 1990 to 2019. However, emphasizing Bangladesh as a case country, this research looks into the factors influencing shrimp export competitiveness taking into account macroeconomic and policy variables. To do so, we used the recently developed Revealed

Abstract This review focuses on an understanding of lipid distribution and deposition dynamics in Atlantic salmon and explores the extent to which these can be predicted through multi-dimensional modeling. The methodology used to measure lipids can have an impact on their assessment and considerable work has been done to standardize and develop robust rapid assessment measures. The distribution of

Abstract A smart aquaculture management system (SAMS) based on the Internet of Things (IoT) has recently gained much attention for fulfilling the growing demand for aquaculture products. The SAMS uses cutting-edge sensing technologies with a modern networking system to continuously monitor water quality, animal health, and feeding behavior to improve the production yield. This review aims to comprehensively

Abstract The impact that added competition of imported mussels from Chile might have had on market prices is one of the main reasons given to explain the decrease in the economic performance of the mussel aquaculture sector in the European Union (EU) in the last two decades. This hypothesis has not yet been tested. In this article we test empirically for price leadership and market integration in the

Selenium (Se) is an important micronutrient that has been used in aquafeeds for the normal growth, welfare and health of aquatic animals. Through nanotechnology, Se can be converted into nanoparticles that are more bioavailable, utilized and absorbed by aquatic animals. However, this is still a new and emerging area of research in aquafeeds. This paper aims to review the effect of Se and Se nanoparticles

Abstract With its long coastline, vast exclusive economic zone (EEZ), skilled labor force, advanced technology, and one of the largest seafood markets in the world, the United States could be a major marine aquaculture producer of fish, mollusks, crustaceans, and marine algae. Despite all its promise, U.S. marine aquaculture production is tiny relative to its potential. The constraints often cited

Paracetamol (APAP) is one of the most widely used non-steroidal anti-inflammatory drugs, which is frequently detected in various water bodies. Studies are limited about its toxic effects and mechanisms on non-target aquatic organisms. In this study, an estuarine bottom-dwelling fish named Mugilogobius chulae, distributed in southern China, was selected as experimental species and the changes of PXR

The transition to include in vitro-based data in chemical hazard assessment has resulted in the development and implementation of screening assays to cover a diversity of biological pathways, including recently added assays to interrogate chemical disruption of proteins relevant to thyroid signaling pathways. Iodotyrosine deiodinase (IYD), the iodide recycling enzyme, is one such thyroid-relevant endpoint

Inland recreational fisheries provide numerous socio-economic benefits to fishers, families and communities. Recreationally harvested fish are also frequently consumed and may provide affordable and sustainable but undervalued contributions to human nutrition. Quantifying the degree to which recreationally harvested fish contribute to food security and subsistence is impeded by lack of data on harvest

Driven by anthropogenic pressure, Antibiotic resistance genes (ARGs) could transfer from the environmental resistome into human commensals or even pathogens. The transport of ARGs through aquatic ecosystems is crucial and has attracted attention. Here, we employed metagenomic and binning to compare ARGs profiles, their co-occurrence with metal resistance genes (MRGs) and mobile genetic elements (MGEs)

Marine ecosystems are currently subjected to dual stresses of chemical pollution and climate change. Through a series of laboratory experiments, this study investigated the impact of exposure to chemical contaminant such as DDT or copper (Cu), in combination with cold or warm temperature extremes on the marine medaka fish Oryzias melastigma. The results showed that extreme seawater temperatures (i

The environmental pollutant 3,3’-dichlorobiphenyl (PCB-11) is a lower-chlorinated polychlorinated biphenyl (PCB) congener present in air and water samples. Both PCB-11 and its metabolite, 4-PCB-11-Sulfate, are detected in humans, including in pregnant women. Previous research in zebrafish (Danio rerio) has shown that 0.2 μM exposures to 4-PCB-11-Sulfate starting at 1 day post fertilization (dpf) increase

Among the anthropogenic sources releasing metallic species into the marine environment, the galvanic anode cathodic protection system (GACP) is widely used to protect submerged metallic structures from corrosion. Galvanic anodes are an alloy of metals of which the main component is aluminum or zinc. Very few studies were performed to study their potential biological effects. We investigated the chronic

Sulfide are widely accumulated in aquatic environments under anaerobic conditions, which cause health problems of aquatic animals, yet their toxic effects to benthic bivalves are not well understood. We investigated the effects of sulfide on innate immunity of the blood clam Tegillarca granosa. Immunity-related indicators and hemolymph microbiota were investigated in the clams exposed to sulfide (via

Due to increasing anthropogenic impacts, heatwaves and prolonged exposure to elevated concentrations of ammonia (HEA) may occur in aquatic environments as a single stressor or a combination thereof, potentially impacting the physiology of exposed animals. In the current study, common water fleas Daphnia magna were exposed for one week to either a 5°C increase in temperature, an increase of 300 µmol

Achieving scientific impact is a fundamental marker of research success, yet the quantification of impact is inherently difficult. This topic was summarised in the context of literature reviews in aquaculture in Issue 14-1 of Reviews in Aquaculture, where it was suggested that impact is enhanced and accelerated through increased collaborative efforts between academic institutions and industry research

Risk assessment of hydrophobic organic compounds (HOCs) is difficult because maintaining a well-defined exposure during aquatic toxicity testing is challenging due to the limited water solubility and various loss processes such as volatilization, biodegradation and sorption. Passive dosing techniques help to overcome these challenges by providing a well-controlled and solvent-free exposure. In this

Meeting the objectives of sustainable fisheries management requires attention to the complex interactions between humans, institutions and ecosystems that give rise to fishery outcomes. Traditional approaches to studying fisheries often do not fully capture, nor focus on these complex interactions between people and ecosystems. Despite advances in the scope and scale of interactions encompassed by

Tuna Regional Fisheries Management Organizations (RFMOs) are responsible for conservation and sustainable management of transboundary tuna resources in Exclusive Economic Zones and Areas Beyond National Jurisdiction (ABNJ). The data collected and analyses performed by tuna RFMOs are one of the main sources of scientific information supporting the management, sustainable use and conservation of biodiversity

Abstract We analyze fish pricing in the São Paulo wholesale market, the second largest seafood market in South America. Quantitative price analysis is complemented by interviews with participants in the value chain to answer how the multitude of fish products supplied in this market are related and the challenges facing future growth. The results reveal a clear separate pricing of domestically produced

It has been more than 100 years since fish were first described to move to deep waters as size increased, termed ‘Heincke's Law’. However, large-scale studies on ontogenetic shifts are rare compared with increased reports of distributional changes in response to temperature, often confounded with the ontogenetic shifts. We fill this gap by examining the distribution of ten abundant groundfish species

Humans have introduced species out of their native areas for millennia, and characterising these historical introductions can provide insights into the long-term progress of invasion processes. Here, archival sources and other historical documents are used to describe the motivations, negotiations and actions leading to fish and crayfish introductions into Spain in the second half of the 16th century

In the aquaculture feed industry, fishmeal is widely used as a source of animal protein due to its high palatability, excellent amino acid profile and increased digestibility. However, the incorporation of fishmeal in aquaculture diets increases the costs of production due to the declining wild fish stocks hence an urgent need to search for sustainable and cheaper alternative protein sources. The use

Arsenic pollution in freshwater poses a serious threat to aquatic organisms. However, dissolved organic matter (DOM) in water can modulate arsenic environmental toxicity by either suppressing or promoting its bioaccumulation. In this study, we investigated the toxicity, bioaccumulation, and biotransformation of inorganic arsenic (arsenite AsIII and arsenate AsV) combined with two types of DOM, i.e

4-octylphenol (4-OP), a toxic estrogenic environmental pollutant, can threaten aquatic animal and human health. However, toxic effect of 4-OP on fish has not been reported. To investigate molecular mechanism of gill poisoning caused by 4-OP exposure, a carp 4-OP poisoning model was established, and then blood and gills were collected on day 60. The results demonstrated that gill was a target organ

Models are important tools to address sustainability challenges associated with developing aquaculture at farm, regional and global scales. Farm-scale models (FSMs), which are integrated mathematical models developed to simulate farm operations, can quantify energy, mass or economic input flows and predict a variety of outputs such as fish biomass, waste and by-products. The variety of farming systems

Chile is the second largest producer of salmon (only behind Norway), and high amounts of antimicrobials are used during the marine stage, mainly florfenicol. Intensive antimicrobials use is a relevant concern, prompting the urgent need for use reduction and advancements towards more restricted, efficient application. This review describes the historic and current use of antimicrobials in Chilean salmonid

Abstract The U.S. catfish aquaculture industry is arguably one of the earliest aquaculture segments in the world to industrialize, and a pioneer in demonstrating the benefits of innovation-driven aquaculture supply chain development over wild-harvested fisheries. However, the industry substantially contracted through the 2003–2013 period. High and volatile feed prices, volatile farm prices, a rapid

The intrinsic ability of microalgae to accumulate high amounts of carotenoids has made them the preferred aquatic organisms of biotechnological exploration for carotenoid production. To continuously innovate and modify microalgal bioprocesses, aquaculture scientists have been working hard for the past decades in a forward-looking way, and mixotrophic cultivation of microalgae is deemed as a promising

In the search for protecting biodiversity, enhancing sustainable resource use, and minimizing conflict among users, spatial planning is now ubiquitous around the globe. Acquiring maps of fishing activity is critical to account for the interests of fishers, but fisheries are generally underrepresented in spatial plans. We conducted a quantitative systematic literature review on how fisheries data have

The current study involved exposing adult F0 Gulf killifish (Fundulus grandis) to Macondo-252 oil for 36 to 44 days and assessing the effects of this oiling on the swimming performance and morphology in two generations of progeny reared in clean water. Following exposure to oil, the F0 fish were used as broodstock to generate four lineages of F1 fish using a full-matrix mating design derived from the

The neurotoxic secondary metabolite β-N-methylamino-L-alanine (BMAA) and its structural isomer 2,4-diaminobutyric acid (DAB) are known to be produced by various phytoplankton groups. Despite the worldwide spread of these toxin producers, no obvious role and function of BMAA and DAB in diatoms have been identified. Here, we investigated the effects of biotic factors, i.e., predators and competitors

It is challenging in fisheries stock assessment to estimate cohort dynamics from length-based data for hard-to-age stocks, and existing approaches, for example, age-structured catch-at-length models (ACL) are unable to account for length-dependent processes within each cohort. Fisheries-dependent data are usually considered the default input to stock assessment models. However, with widespread recognition

By-catch is the most significant direct threat marine megafauna face at the global scale. However, the magnitude and spatial patterns of megafauna by-catch are still poorly understood, especially in regions with very limited monitoring and expanding fisheries. The Indian Ocean is a globally important region for megafauna biodiversity and for tuna fisheries, but has limited by-catch data. Anecdotal

Aquaculture produces about half the fish consumed globally and is the fastest-growing food sector. In Africa, fish is one of the major sources of animal protein, and although the need for increased production of farmed fish to make up for the decline in capture fisheries is acknowledged, efforts put into aquaculture in the continent have not yielded commensurate results. The success recorded in aquaculture

Abstract Invasive species are a global concern. After an invasive species establishes, they often disrupt ecosystems leading to new dynamics and species interactions, making management efforts difficult. Panarchy theory is a conceptual framework to account for the dual and seemingly contradictory characteristics (stability and change) of all complex systems across distinct spatial and temporal scales

Chemical contaminants are one of the causes of the ongoing degradation of coastal and estuarine nurseries, key functional habitats in which the juveniles of many marine species grow. As chemical contaminants can cause a decrease in the energy available and induce defence mechanisms reducing the amount of energy allocated to life history traits, quantifying their effect on the fitness of juvenile fish

In marine organisms, differing degree of sensitivity to ocean acidification (OA) is expected for each life stage, and disturbance at one stage can carry over into the following stage or following generation. In this study we investigated phenotypic changes of sperm and larvae of the sea urchin Paracentrotus lividus in response to different pH conditions (8.0, 7.7, 7.4) experienced by the parents during

The presence of nanoplastics in aquatic environments is a global problem. Accumulating evidence shows that nanoplastics can accumulate in fish and influence internal organs. However, it is still unknown if nanoplastics can impair skin cells (keratinocytes and ionocytes), which play critical roles in maintaining body fluid homeostasis. In the present study, zebrafish embryos were exposed to polystyrene

Phytoremediation potential of Azolla in removal of nitrogen from wastewater has been promising. However, little is known about the response of Azolla to high concentrations of nitrogen. In this study, the responses of four Azolla species to different concentrations of total nitrogen ranging from 0 to 180 mg L−1 were examined. The responses varied among different species, and the high nitrogen-tolerant

Benzotriazole ultraviolet stabilizers (BZT-UVs) are added to various products to prevent damage caused by UV light and have emerged as contaminants of concern. Although BZT-UVs are detected in aquatic biota globally, few studies have assessed their potential toxic effects. The objective of the present study was to assess effects of 2-(2H-Benzotriazol-2-yl)-4-methylphenol (UV-P) on reproductive success

While efforts to reduce illegal fishing have been underway for some time, market data suggest the volume of illegal fish in the markets is not decreasing significantly. One issue that may be driving this is the difficulty in imposing meaningful sanctions. We discuss an alternative approach aimed at reducing illegal fishing. A State's open register allows relatively unassociated vessels to purchase

Water contamination poses an important challenge to aquatic fauna, including well-documented effects on amphibian larvae. However, little is known about how contamination during the larval stages may affect post-metamorphic phases, or whether resistance may have evolved in some populations. In this work, we tested the hypothesis that chronic exposure to ammonium (a common contaminant in agroecosystems

Industrial operations such as surface mining, road building, and aggregate washing result in high concentrations of suspended particles (Total Suspended Solids; TSS) in surface waters which must be treated prior to discharge into fish-bearing waters. A common industrial practice is to add flocculants to improve the efficacy and speed of TSS sedimentation. A significant environmental issue even small

Imidacloprid (IMI) is a widely used neonicotinoid insecticide that has toxic effects on nontarget organisms. 1,8-Cineole (eucalyptol) is purified from essential oils in several aromatic plants and can prevent xenobiotic toxicity. The kidney is a major organ for xenobiotic elimination and thus has high risk of exposure. The purpose of this research was to clarify the effect of IMI exposure on autophagy

Zinc pyrithione (ZPT) is a frequently used organometallic biocide, carrying potentially adverse consequences to multiple species in the environment. Previously we have demonstrated its embryonic, organ developmental and liver metabolic toxicity of zebrafish. However, details of ZPT toxicity during embryogenesis are still limited. The present study was designed to evaluate the effects and possible mechanisms
