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 most evident in ommastrephid nerito-oceanic squid since their life cycle is associated with boundary currents that are changing with climate change. The inter-annual variability in catch presents challenges for fishers and managers due to the ‘boom-or-bust’ nature of the fishery. A key barrier to rational management of squid fisheries is the low level of development of fishery forecasting. Despite substantial progress made in relating squid population dynamics to environmental variability and change, several challenges remain to develop forecast products to support squid fisheries management. Ideally, squid fisheries management needs a forecasting system that includes all time-scales of forecasting, and especially short - and medium-terms forecasts. The present overview first provides current knowledge of the effects of climate change and variability on squid population dynamics, challenges and opportunities to advance ecological-fishery forecast products, and finally a roadmap is proposed for future development of forecasts products to support squid sustainable fisheries management. As for the adoption of specific forecasting methods to the squid fishery management process, what is important is the relationship between needs, feasibility, and the ultimate success of a forecast will be determined by whether it is used by end-users.

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 change on fishery-dependent communities and finally highlights climate change adaptation strategies adopted by fishers. A systematic approach was employed to search and select relevant published literature used in this review paper. The reviewed literature indicated the challenge of declining fish catches in several fishing communities, which was associated with climate change and variability. Changes in mean temperature, rainfall quantities and patterns, sea-level changes, water salinity, and lake levels affect fish productivity. Fishers in sub-Saharan Africa adopt different strategies to sustain their livelihoods and food security, which are being threatened by climate change. Adaptation strategies employed by fishers to cope with the impacts of climate change include, changing fishing gear, migration, targeting new species, and increasing fishing grounds and time spent fishing. To promote socio-ecological adaptation and fisheries sustainability, it is crucial to understand the impacts of climate change at a local level, which would inform policy and fisheries management practices.

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. In this synthetic review, a practice-oriented framework is used to show that innovations which contribute to adaptation in the aquaculture sector include changes to the material, procedural and informational dimensions of practice. The material dimension is dominated by concerns with cost and competitiveness, whereas for the procedural dimension issues of skills and compliance arise, and for the informational dimension, key issues are trust, reliability and persuasiveness. A secondary classification into ten types of practices identified additional associations with adaptation mechanisms, for instance, technical practices are followed and adjusted to reduce and manage risks, while many infrastructural and technological practices aim to control rearing environments. Innovation has been driven more by concerns with increasing productivity, disease control, and food safety than extreme weather events and climate change. Nevertheless, many new practices have significant implications for adaptation. This study also shows that innovation and adaptation are timebound and face social limits, and these are better understood when different dimensions and types of practice, sources of innovation, and mechanisms of adaptation are distinguished.

Abstract Recreational fisheries are social-ecological systems (SES), and knowledge of human dimensions coupled with ecology are critically needed to understand their system dynamics. Creel surveys, which typically occur in-person and on-site, serve as an important tool for informing fisheries management. Recreational fisheries creel data have the potential to inform large-scale understanding of social and ecological dynamics, but applications are currently limited by a disconnect between the questions posed by social-ecological researchers and the methods in which surveys are conducted. Although innovative use of existing data can increase understanding of recreational fisheries as SES, creel surveys should also adapt to changing information needs. These opportunities include using the specific temporal and spatial scope of creel survey data, integrating these data with alternative data sources, and increasing human dimensions understanding. This review provides recommendations for adapting survey design, implementation, and analysis for SES-focused fisheries management. These recommendations are: (1) increasing human dimensions knowledge; (2) standardization of surveys and data; (3) increasing tools and training available to fisheries scientists; and (4) increasing accessibility and availability of data. Incorporation of human dimensions information into creel surveys will increase the ability of fisheries management to regulate these important systems from an integrated SES standpoint.

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 oocyte maturation. These methodological differences impose a bias on the outputs of comparative studies of fecundity. For both theoretical and practical reasons, accurate fecundity data are required to inform the decision-making process in terms of environmental policy and the related applications for the control of non-native species and the conservation management of native species and ecosystems. The main aim of the present study was to review briefly the existing fecundity-evaluation methods, to test among-method compatibility, and to develop a new approach that aims to make fecundity evaluation more systematic and transparent. A simulated ‘test’ dataset demonstrated considerable variability in the results obtained from the various existing approaches. The literature review and our analyses revealed a need for standardization. Thus, a new approach is proposed here that is based on multiple sampling throughout the reproductive cycle; provides greater overall detail of the species’ reproductive traits and permits inter-population comparisons.

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 frozen and dry body wall (beche-de-mer), frozen muscle bands, dry aquapharyngeal bulb (flower), along with various pharmaceutical and nutraceutical extracts. This species is also a candidate for aquaculture due to its high marketability for food and bioactive products. Despite its naturally high abundance, C. frondosa is a temperate-polar slow-growing species with annual spawning; therefore, a precautionary approach must be taken to develop best practices for management of this resource. The present contribution reviews the biology, ecology, biochemical properties, harvesting and trade, and the potential aquaculture of C. frondosa. This comprehensive synthesis, including 10 theses, 197 scientific papers and 47 reports, aims to provide a framework for future research by highlighting areas of concern for academic studies, fishery management, and aquaculture of cold-water sea cucumber species.
摘要对海参的需求和高昂的市场价格导致亚洲和印度太平洋许多传统物种的野生种群崩溃。因此，近几十年来，新物种被引入市场，包括Cucumaria frondosa。20世纪80年代，美国出现了C.frondosa渔业，并在冰岛、加拿大和俄罗斯迅速发展。商业产品包括冷冻和干燥的体壁（beche de mer）、冷冻肌带、干燥的咽球（花），以及各种药物和营养品提取物。该物种也是水产养殖的候选物种，因为它在食品和生物活性产品方面具有很高的市场性。尽管其天然丰度很高，但C.frondosa是一种温带极地缓慢生长的物种，每年产卵；因此，必须采取预防措施，制定管理这一资源的最佳做法。本文综述了C.frondosa的生物学、生态学、生物化学特性、收获和贸易以及潜在的水产养殖。这份综合报告包括10篇论文、197篇科学论文和47份报告，旨在通过突出学术研究、渔业管理和冷水海参养殖关注的领域，为未来的研究提供一个框架。

Abstract Shrimp aquaculture over the years has made tremendous progress. The application of modern biotechnological tools, including next-generation sequencing (NGS) techniques, has revolutionized the genomics of commercially important aquaculture species. Genetic improvement programmes targeting desired economic traits are being implemented worldwide with knowledge gained through development of genetic resources. These genetic resources form the basis to understand and develop the strategy for selective breeding of aquaculture species for improved performance. In view of serious disease outbreaks in shrimp aquaculture, and lack of understanding of key biological, reproductive and physiological functions at the molecular level, it has become critical to develop and exploit the available genomic resources to the full potential. This review presents recent progress in development of genetic resources such as transcriptomics, genomics, DNA markers and linkage maps having future potential in selective breeding programmes for commercially important penaeid species.

Abstract The ide Leuciscus idus is a large-bodied cyprinid native to freshwaters around the Baltic, Black, Caspian, White, Barents, Kara, Laptev and North seas as well as the Aral Sea region. Historically an important commercial species, the ide is used in recreational fisheries and as an ornamental fish, and is subject to translocation and stocking events. The ide is less well-studied than many European cyprinids and relatively little is known of the risks it poses to native species and ecosystems where introduced. The present review and meta-analysis examine available data on the ide’s environmental biology to provide an assessment of its potential invasiveness. A long-lived, omnivorous species, the ide is a habitat generalist that inhabits lowland rivers and nutrient-rich lakes, but also some brackish waters where it is facultatively anadromous. The ide displays variable age and length at maturity and asymptotic growth in body length, can be highly productive and migratory, and can withstand variable environmental conditions. Despite several attributes that should facilitate acclimation to novel environments, the ide has established relatively few self-sustaining populations outside its native range, and is therefore not currently considered to be invasive. However, as introductions are likely to continue, increased propagule pressure could lead to the development of invasive non-native populations in some locations.

However, as introductions are likely to continue, increased propagule pressure could lead to the development of invasive non-native populations in some locations.","PeriodicalId":21183,"journal":{"name":"Reviews in Fisheries Science & Aquaculture","volume":"29 1","pages":"512 - 548"},"PeriodicalIF":11.5,"publicationDate":"2020-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23308249.2020.1822280","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48804984","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 Mariculture insurance policies issued by the government can ensure the sound development of mariculture insurance and improve risk management capacities in mariculture. 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 attempt stage of commercial insurance (1982–1993), the exploratory stage of mutual insurance (1994–2010) and the steady development stage of policy-based mutual insurance (2011-present). Correspondingly, this study found that policy focuses have evolved from single to diverse and normative policies have been emphasized in recent years; policy release authorities have increased and cooperation between different departments has appeared; policy power has intensified. Meanwhile, Chinese mariculture insurance policies faces several challenges, including unsound legal and regulatory system, insufficient fiscal subsidies and imperfect catastrophe risk management mechanism. Therefore, improving the legal system, strengthening the supervision and management, increasing and diversifying fiscal support, providing technical and talent support and improving catastrophe risk management mechanism by the government should be paid great attention to promote the scientific development of mariculture insurance.

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 role in maintaining ecosystems, including aeration of water, pest control, photosynthesis, nutrient cycling, respiration, soil fertility, and water quality. Wild rice-fish cultivation would be an ecosystem approach due to the positive culture attributes in terms of environmental benefits. Human consumption of wild rice and fish would provide a complementary, healthy, nutritious, and low-fat diet, with rich in carbohydrate, protein, minerals, and vitamins. Ideally, wild rice-fish integration could provide a wide range of social, economic, and ecological advantages, including food production, human nutrition, livelihoods, income, biodiversity conservation, and ecosystem services. Despite opportunities and potential benefits in North America, wild rice-fish culture has not yet been practiced. Empirical research with key stakeholders’ involvement need to address social, economic, and ecological challenges for wild rice-fish cultivation to increase food productivity and environmental sustainability.
