AbstractThe COVID-19 pandemic created an unprecedented shock to capture fisheries and aquaculture sectors. This scoping review of 670 articles explored the spatial, temporal, and thematic coverage of this event. The search period was January 1, 2020 to February 7, 2022. Articles were mainly peer-reviewed journals (88%) with the remainder from the gray literature (12%). Studies were performed at the global (21%), multi-country (11%), national (45%), and sub-national (23%) levels. Most studies involved primary or secondary data collection (71%) and the remainder were either review articles (17%) or commentaries (12%). Among the studies using primary and secondary data, nearly half (49%) were performed in the first five months of the pandemic (March to July 2020), and 84% within the first year of the pandemic (March 2020–February 2021). There were many studies in South and Southeast Asia, Southern Europe, China, and the United States, and fewer studies in other regions. The pandemic created challenges and opportunities, with heterogeneity in impacts among industrial and small-scale sectors, production methods, geographies, value chains, and by gender. Cumulative impacts from climate change and conflicts contributed to pandemic-related hardships. Increased unemployment and inflation led to rising food insecurity for small-scale producers, fishworkers, and low-income households. Aquatic food intake was more severely affected than other food groups during lockdowns, and it decreased more in low- and middle-income countries than in high-income countries. Responses were diverse, reflecting the capacity and resources of a country, but in general there was unprecedented public support to sustain the private sector (i.e., income support, tax relief, subsidies). As this study focused mainly on the first year of the pandemic, future work is needed to identify which groups exited the pandemic stronger or weaker, what factors enabled some populations to bounce-back, how the crisis affected value chains, and the effectiveness of interventions.Keywords: AquaculturefisheriesCOVID-19livelihoodresiliencesmall-scale AcknowledgmentsWe would like to thank Claire Twose, Johns Hopkins Welch Medical Library, for assisting with the literature review search.

Abstract Accumulating evidence has demonstrated a decrease in post-release survival of angled Atlantic salmon (Salmo salar) during periods of warm water temperatures. Consequently, the application of water temperature-related fishery closures by resource managers is gaining interest. Here, the role of water temperature-related fishery closures in recreational Atlantic salmon fisheries is reviewed by (1) presenting a synopsis of factors that could influence the effectiveness of these fishery closures, (2) using novel fisheries and water temperature data from Eastern Canada, to illustrate how various closures can affect management outcomes, and (3) discussing alternative options for managers to implement such fishery closures. Results suggest there are a number of considerations when implementing a water temperature-related fishery closure. For populations meeting conservation requirements, results show that additional angling opportunities can occur at minimal conservation cost by applying morning-angling-only protocols in rivers during periods of reduced catch and release and moderately warm water temperatures. The impact on salmon populations, however, will be higher in situations where high catch and release rates overlap with warm water periods (e.g. when day-night water temperatures remain in excess of 20 °C or remain high during the summer) or occur over prolonged periods of extreme warm water temperatures. In situations where resource managers have few resources and need to implement water temperature-related fishery closures on a large spatial scale, it is recommended that strategically chosen index rivers to inform water temperature-related fishery closures are used. In rivers with healthy salmon populations, angling opportunities during periods of warm water could be considered if supported by enhanced monitoring (e.g., monitoring salmon abundance, spatially-structured water temperature data, and mandatory catch reporting (catch and effort)) that optimize tradeoffs between socio-economic benefits and conservation.

Abstract The queen conch (Aliger gigas) is an important fishery resource species in the Caribbean region, increasingly threatened by overharvest. The species’ life history is characterized by density-dependent reproduction, benthic egg masses, and a 2-4-week planktotrophic period with potential for long-distance dispersal. This review focuses on veliger growth, development, and settlement, especially as related to environmental variables, and larval duration and behavior relevant to transport. More than 3000 plankton collections for queen conch made throughout the region show that most veligers occur in the upper water column during the warmest season, with evidence for a positive association between abundance of late-stage veligers and subsequent abundance of juveniles in nursery grounds. Biophysical models based upon the best information on veliger duration and vertical movement yield predictions on population connectivity and can be used in design for networks of marine protected areas. While the earliest genetic studies suggested an open panmictic Caribbean population, more recent molecular genetic results show that populations exhibit a continuum-like structure, and self-recruitment occurs in certain localities. The current state of knowledge of early life history and connectivity for queen conch is discussed in terms of recruitment potential, climate change, and management for sustainable fisheries.

Abstract Routinely, fish encounter stressors and conditions that require the use of anaerobic exercise, including escaping predators, capturing prey, and interacting with fisheries. Although anaerobic metabolism rapidly yields energy to support locomotion, it also accelerates the depletion of energy stores, and accumulates potentially damaging metabolites, relative to aerobic metabolism. During recovery from intense exercise, animals are vulnerable and may forgo opportunities (e.g., foraging, mating). Recovery is thus likely under strong selection pressure. Despite the fact that recovery is essential for life, relatively little attention has been given to its importance for fitness and survival. Here, the ecology and physiology of recovery following intense exercise are reviewed using Pacific salmon (Oncorhynchus spp.) as a model, though findings are relevant to a wide range of species given that the need for recovery is ubiquitous. Specifically, when and why salmon use anaerobic exercise across their lifecycle, the physiological consequences of this extreme exercise, and the recovery process are considered. The importance of considering recovery for effective management and conservation of Pacific salmon species is discussed, and examples to highlight meaningful ways in which knowledge of recovery can be applied to problems facing fish are provided, with implications widely applicable to all fishes. Given current and projected climate scenarios, understanding the role of temperature in recovery will become progressively more important, and should be an explicit consideration when assessing vulnerability.

Abstract Blue foods are highly diverse and are supported by a wide range of ecosystems, production practices, and markets. This diversity influences resiliency of aquatic food systems, their capacity to contribute to global food security, and the spread of knowledge and adoption of innovations. Here, trends in diversity and determinants of diversity in capture fisheries and aquaculture production were examined at the global and country level. Results show that fisheries production is more diverse than aquaculture production, and that social and economic factors appear to be as important for species diversity as biophysical factors. The diversity of fisheries is diminished when governance is weak, and this poses challenges for managing fisheries for nutrition-sensitive food production. It also illustrates the greater potential of aquaculture to address challenges related to access given that less diversity in aquaculture is created by economies of scale making food more accessible among lower income groups.

Abstract China effectively utilizes industrialization to enhance the productivity growth of deep-sea cage mariculture. This study reviews the industrialization of deep-sea cage mariculture in China, focusing on three sectors: small-scale cage mariculture, large-scale cage mariculture, and ocean-engineering cage mariculture, based on different productivity levels. The industrialization process is divided into three phases, considering technology development, transformation, and adoption. The performance of each phase is analyzed, revealing that Chinese intensive management of production element resources has led to the successful cultivation of domestic salmon and the development of various open net cage systems, ultimately promoting industrialization of the upstream sectors. It is worth noting that China has close business relations with Norway and Brunei. Despite these successes, some shortcomings still exist, including low profits and the risk of oligopoly formation among mariculture enterprises, which can oversaturate the livelihoods of fishermen.

Abstract Creatine is a popular ergogenic sport supplement used to improve exercise performance and muscle growth in athletes. Further, studies suggest protective effects of creatine in neurodegenerative diseases, type 2 diabetes, osteoarthritis, fibromyalgia, aging and fatty liver disease in humans. Similarly, the versatility of creatine, as a supplement or feed additive, has been evaluated in different animal production systems, including terrestrial livestock, poultry and aquaculture fish species. Some of the observed effects are increased antioxidant activity and flesh quality, improved lipid homeostasis as well as enhanced overall productive performance. Despite creatine being synthesized endogenously, this capacity might be insufficient to adequately cover the creatine needs in fish fed diets formulated with ingredients devoid of this nutrient, notably plant protein feedstuffs. As aquaculture industry moves toward sustainability, removal of creatine-rich dietary ingredients, such as fishmeal, in aquafeeds will likely further increase in coming decades. Thus, under this scenario it might be necessary for dietary supplementation of creatine to support optimal fish productive performance and product quality. This review describes the current knowledge of creatine physiology and metabolism in fish, and highlights possible parallels with metabolism in livestock species, mammalian models and human as well as the benefits obtained from creatine supplementation.

This review describes the current knowledge of creatine physiology and metabolism in fish, and highlights possible parallels with metabolism in livestock species, mammalian models and human as well as the benefits obtained from creatine supplementation.","PeriodicalId":21183,"journal":{"name":"Reviews in Fisheries Science & Aquaculture","volume":"31 1","pages":"420 - 451"},"PeriodicalIF":11.5,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48628852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Mixed fisheries occur when multiple species are caught together and harvested by multiple fleets. The biological and technical interactions in mixed fisheries distinguish them from single-species fisheries, which makes them challenging for their assessment and management. The present knowledge synthesis reviewed pertinent policy documents and academic databases for twenty-three mixed fisheries worldwide; aiming to characterize attributes of mixed fisheries, provide overviews on their assessment and management, assess current research progress, and identify key factors that impact management effectiveness. Mixed fisheries were found to exhibit varying characteristics worldwide, rendering the implementation of universal management solutions unlikely. While mixed fisheries stock assessment and management are mostly based on single-species approaches, additional mixed fisheries considerations were incorporated at various scales, including multispecies, sector-specific, fishery, and ecosystem levels. Ecosystem-wide management considerations were the most significant contributor to improved management performance in terms of conserving stock biomass and preventing overfishing, underscoring the merits of the Ecosystem-based Fisheries Management (EBFM) principle. Mixed fisheries research demonstrated regional and thematic variations, with the most popular topics addressing immediate and practical management concerns, and the less frequently discussed topics offering valuable insights related to climate change and socio-ecological perspectives. The synthesis identified the available management approaches for mixed fisheries from different jurisdictions, yet their diversity highlighted a lack of global consensus on best management practices. Future mixed fisheries will benefit from balancing tradeoffs between ecological and socio-economic needs, implementing EBFM, adopting diverse and harmonized management tools, and prioritizing monitoring efforts.
