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 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 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

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

Abstract The term “adaptive zone” appeared in paleontology and evolutionary biology, where it was not clearly defined, and gradually became obsolete and is now rarely used. This paper provides an updated definition of the term applicable in modern ecology and biogeography. It is shown that an adaptive zone is a particular case of Petersen-type communities. Sixteen implications were formulated that

Abstract Heavily melanized gills in crustaceans, often referred to as black gill, have been reported in both wild and cultured marine species. Tissue melanization is generally the result of a response of the crustacean innate immune system to the presence of an irritant or pathogen. While black gill can be caused by a variety of abiotic stressors and nutritional deficiencies, biotic agents are the

Abstract Collectively known as eucheumatoids, Eucheuma denticulatum, Kappaphycus alvarezii, K. malesianus, and K. striatus are the main farmed seaweed species in the Philippines. The success of seaweed farming for over five decades in the country is due, in part, to the high diversity of cultivars maintained by the Filipino farmers. Notwithstanding the fact that many eucheumatoid cultivars are presently

Abstract Finding ways to keep global warming under 1.5 degrees Celsius is urgent and will need a portfolio of solutions. Seaweeds are marine photosynthetic organisms that humans harvest either from the wild or farm, to be used in many applications and providing various ecosystem services. Large scale farming of seaweeds for absorbing carbon has lately been promoted as a climate “fix”. The major shortcomings

Abstract The Senegalese coasts have high productivity of fishery resources due to the frequency of intense up-welling system that occurs along its coast, caused by the maritime trade winds making its waters nutrients rich. This phenomenon has contributed greatly to the practice and development of fishing, which is a very important activity in Senegal. Fishing plays a primordial role in the socioeconomic

Abstract We reflect on the innovation process that led to the development of the pulse trawl that was successfully trialed at a commercial scale, but eventually ended with the European Parliament passing legislation to ban its use. The ban was imposed despite published and emerging evidence that suggested that the environmental performance and catch efficiency of the pulse trawl was superior to the

Abstract The development of water management infrastructures, such as dams and canals, are important components of society’s response to feed a growing human population and to fight climate change. Yet, these changes in land use can also increase the transmission risk for waterborne diseases. Transmission risk associated with artificial reservoirs has been extensively documented for schistosomiasis

Abstract Genetic resources are the building blocks for aquaculture breeding programs, biotechnology and conservation. The Convention on Biological Diversity and the Nagoya Protocol are international frameworks for access and benefit sharing (ABS) concerning: (a) the collection and use of genetic resources and associated traditional knowledge; and (b) sharing the benefits of their use with the provider

Abstract A recent publication by Belton et al. raises points for policy-makers and scientists to consider with respect to the future of aquaculture making recommendations on policies and investments in systems and areas of the world where aquaculture can contribute most. Belton et al. take an ‘us versus them’ approach separating aquaculture by economics, livelihood choices, and water salinity. They

Abstract Whilst the aquaculture sector continues to grow and make an ever increasing contribution to world food supplies, there is a need to ensure that the sector continues to develop in a socially, economically and environmentally sustainable manner, in line with the UN sustainable development goals. The present paper focusses on the major perceived sustainability issues related to feed inputs for

Abstract Sustainable domestic aquaculture development is a critical component to achieving greater U.S. seafood security in the future, yet detrimental allegations have corrupted public support. A variety of longstanding and inaccurate myths and assumptions directed at offshore aquaculture farming and its regulation have been foisted on the public. This paper refutes the most prevalent critiques by

Abstract Despite the global scale of gillnet bycatch, universal measures that effectively reduce bycatch of seabirds in gillnets have not been found. Bycatch in coastal gillnet fisheries is an ongoing threat for several seabird species. Strategies to reduce seabird bycatch in gillnet fisheries were evaluated, focusing on the effectiveness of time-area fishing restrictions and gear-switching to meet

Abstract Extracellular vesicles (EVs) from various eukaryotes range from 30–1000 nm in diameter, and contain numerous cargoes, such as nucleic acids, proteins, and lipids with various functions, which might be promising biomarkers or important modulating molecules. Research into the roles of EVs in aquatic animals is in its infancy. Limited studies have confirmed the existence of EVs in different kinds

Abstract Management of anadromous salmon stocks is usually based on an estimate of the spawner-recruitment relationship. A wide variety of estimation approaches have been developed, from simple to complex, and some worthwhile methodologies and auxiliary data are underutilized. The types and quality of the data available determine the most appropriate assessment methodology and the reliability of the

Abstract The queen conch (Aliger gigas) is a culturally and economically important molluskan fishery resource in the Caribbean region showing increasing signs of over harvest. Shallow-water distribution and large size facilitate capture, and internal fertilization and density-dependent reproduction make managing for reproductive biology critical to stock rehabilitation. In fact, the natural lifetime

Abstract This review summarizes the current state of knowledge of pugheadedness in fish. Records in the scientific literature range from detailed descriptions to brief notes and mere remarks. In total, at least 164 species from 60 families were identified to exhibit pugheadedness, with records published over a span of 465 years (1555 − 2020). The main osteological feature behind pugheadedness appears

Abstract The otolith chemistry is one of the most commonly used tools to elucidate the structure of fish stocks. The correct application of this methodology depends on the fulfillment of several assumptions. One of the most relevant assumptions is that the otoliths and water chemistries vary at appropriate spatio-temporal scale in relation to the hypotheses being addressed. Due to the increase in the

Abstract Interactions between spatial dynamics and stock structure in marine fishes have largely focused on stocks in decline; stock structure is rarely re-visited for expanding species. Here, the spatial ecology of Atlantic halibut (Hippoglossus hippoglossus L.), managed as four stocks in the Northwest Atlantic, is reviewed. Halibut collapsed under high exploitation in the mid-19th century, but the

Abstract While a large number of studies have investigated seafood consumption in various markets, surprisingly little is known about the types of seafood sold in retail outlets or their product forms in the USA. This is particularly true for fresh seafood, which is generally regarded as the most valuable product form of seafood. In this article, a unique dataset on retail in-store seafood sales that

Abstract Adult returns to many Atlantic salmon wild and hatchery stocks of the North Atlantic have declined or collapsed since 1985. Enhancement, commercial fishery closures, and angling restrictions have failed to halt the decline. Human impacts such as dams, pollution or marine overexploitation were responsible for some stock declines in the past, but adult returns to river and hatchery stocks with

Abstract Biotelemetry of Atlantic sturgeon Acipenser oxyrinchus oxyrinchus has exposed spawning behaviors in ever-smaller estuaries, surprising for the NW Atlantic’s largest anadromous species. Small estuary — the Nanticoke River and Marshyhope Creek (Chesapeake Bay) — spawning-run adults and their habitat affinities are described based upon direct sampling and biotelemetry for the period 2014–2018

Abstract Aquaponics is the integration of aquaculture and hydroponics where nutrients released by growing fish are utilized by plants grown in a soilless culture, often in a controlled environment. Potential advantages of aquaponics include improved sustainability, reduced resource consumption, and fewer environmental impacts compared to conventional aquaculture. Based on a 2014 survey, it was found

Abstract Management Strategy Evaluation (MSE) is a framework to explore the tradeoffs amongst fishing strategies and assess the consequences for achieving management goals provided sources of uncertainty by means of simulation models (referred to as operating models). Single-species stock assessment often implements simulations for MSE, but the operating models often omit the dynamics of key biological

Abstract The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other anthropogenic-driven threats including global climate change. Both anthropogenic stressors and the COVID-19 pandemic represent significant economic challenges to aquaculture systems

Abstract The demand for caviar has increased in recent years because of its high nutritional and commercial values. Consequently, the wild population of sturgeon has decreased. This has shifted the balance of supply of caviar from wild sturgeon to more from farmed fish. The development of aquaculture has resulted in many technical advances of sturgeon rearing. The same factors that encouraged sturgeon

Abstract Migration timing has evolved in many animals, allowing them to maximize breeding and feeding success by matching seasonal changes in abiotic conditions and resource pulses. These seasonal changes can shift with the climate, resulting in mismatches between migrations and resource availability unless the populations respond through phenotypic plasticity or evolutionary adaptation. It is common

Abstract Globally, cephalopods support large industrial-scale fisheries and small-scale to partly large-scale local artisanal fisheries. They are of increasing economic importance as evidenced by the rapid rise in their global landings from 1950 to 2014. Cephalopods are sensitive to environmental variability and climate change and many if not all species show wide fluctuations in abundance. This is

Abstract Fisheries in Sub-Saharan Africa are vulnerable to the effects of climate change, which include changes in mean temperature, increasing rainfall variability and the occurrence of extreme weather events. This article reviews evidence on the magnitude of climate change and the nature of its impacts on both inland and marine fisheries. In addition, the review also focuses on the impacts of climate

Abstract The importance of innovation for effective responses to climate change is widely asserted, but exactly how and whom innovation helps adapt has received little systematic attention.

Abstract Fishes are characterized by a great diversity of reproductive strategies that often make fecundity evaluation difficult. Unlike marine fishes, a single consensual concept of terminology and definitions is lacking for freshwater fish fecundity. Several approaches are known from scientific literature for evaluating fecundity in batch spawning fishes of indeterminate fecundity and asynchronous

Abstract The demand and high market price for sea cucumber has led to the collapse of wild stocks for many traditional species in Asia and the Indo-Pacific. New species have therefore been introduced to the markets over recent decades, including Cucumaria frondosa. A fishery for C. frondosa emerged in the USA in the 1980s and quickly developed in Iceland, Canada and Russia. Commercial products include

In this research, content analysis has been applied to explore the evolution of mariculture insurance policies since 1982. According to the time sequence of policy promulgation, the period is divided into three stages: the

Abstract Naturally grown wild rice (Zizania sp.) in freshwater lakes and streams with suitable biophysical conditions could provide opportunities for fish cultivation in different parts of the world, including North America. Many fish species prefer wild rice ecosystems for their habitat. Such natural aggregation could inspire wild rice-fish cultivation. Wild rice-fish integration could play a major

Abstract Aquaculture is considered the fastest-growing food supply, invertebrates being a key element; in particular, whiteleg shrimp (Litopenaeus vannamei). They contribute to human welfare, albeit potential negative environmental effects should be properly addressed. Indeed, the environmental impact of aquaculture is lower than using wild captures. Therefore, shrimp aquaculture is reviewed in relation
