Box 303, Linghe Street 42 Dalian 116023 Liaoning, PR China Preface FAO estimates that 79 percent of fisheries are either fully exploited, overexploited or depleted, with only a small number having the chance to recover from depletion. Global marine capture fishery production has declined by 1.6 per cent from 2006 to 2011. During the same period, marine aquaculture production increased by 20.6 per cent. Overfishing and depletion of wild fishery stocks and increasing global demand for seafood from aquaculture determines that the role of mariculture in seafood supply will be critical in the years to come. Environmental challenges of mariculture necessitate improvements and innovation in mariculture management and technologies. UNDP/GEF YSLME Phase II Project aims to foster long-term sustainable institutional, policy and financial arrangements for effective ecosystem-based management of the Yellow Sea. Recovery of depleted fish stocks and improved mariculture production and quality and improved ecosystem health are among the outcomes of the project. Capturing and disseminating IMTA through developing training modules and conduct of training programs are part and parcel of the project approaches to promoting sustainable investment in aquaculture that will lead to a more ecologically sustainable mariculture in Yellow Sea region. Training Module for Integrated Multitrophic Aquaculture in PR China represents the collective efforts of scientists in documenting the practices of IMTA in PR China and elsewhere. It consists of six chapters, starting with an introduction of IMTA development in PR China and other countries, followed by assessment of carrying capacity of IMTA seawaters. In Chapter 3, the modules illustrate IMTA modalities of shellfish-seaweed and shellfish-seaweed-sea cucumber, pond-based IMTA, land-based integrated multi-trophic recirculating aquaculture model and application of IMTA in sea ranching programs. Through case studies, the modules talk about evaluation of ecosystem services of different IMTA models in Chapter 4, introduce two methods to conduct environmental monitoring of IMTA in Chapter 5, followed by prospects and suggestions of IMTA replication in YSLME and coastal areas in other countries. We hope the module can serve as a useful reference to the aquaculture managers, researchers and university students in their pursuit for environmentally friendly aquaculture.

  • Seafood Banquets in Beijing: Consumer Perspectives and Implications for Environmental Sustainability
    [Downloaded free from http://www.conservationandsociety.org on Thursday, June 27, 2019, IP: 139.191.247.3] Conservation and Society 12(2): 218-228, 2014 Article Seafood Banquets in Beijing: Consumer Perspectives and Implications for Environmental Sustainability Michael Fabinyia,# and Neng Liub aAustralian Research Council Centre of Excellence for Coral Reef Studies, James Cook University, Townsville, Australia bDepartment of Sociology, Peking University, Beijing, China #Corresponding author. E‑mail: [email protected] Abstract Understanding the social drivers of increased seafood consumption in China, such as consumer perspectives in banquets, will be crucial if practical strategies to introduce sustainability into this market are to be successfully implemented. Based on 34 semi‑structured interviews with key informants including seafood restaurant operators, seafood consumers and seafood traders, this study investigated seafood consumer attitudes and behaviours in Beijing seafood restaurants. The results and discussion is divided into sections that address the popularity and reasons behind the popularity of: 1) seafood banquets in general; 2) fish at banquets; 3) other forms of seafood at banquets; and 4) preferred characteristics and qualities of seafood at banquets. The consumption of certain types of seafood such as live reef fish and sea cucumber is becoming increasingly popular, while the consumption of shark fin is decreasing in popularity. Awareness and concern about sustainability and traceability issues were relatively low, and more significant themes for understanding consumer preferences about seafood include social status and prestige, food safety and quality, and health and nutrition. The paper concludes by demonstrating the implications for market‑based interventions and government regulation. Keywords: China, consumption, markets, fisheries, banquets, seafood INTRODUCTION this seafood is imported from other countries.

  • Variations in Tetrodotoxin Levels in Populations of Taricha Granulosa
    www.nature.com/scientificreports OPEN Variations in tetrodotoxin levels in populations of Taricha granulosa are expressed in the morphology of their cutaneous glands Pedro Luiz Mailho-Fontana1*, Carlos Jared1, Marta Maria Antoniazzi1, Juliana Mozer Sciani 2, Daniel Carvalho Pimenta 1, Amber N. Stokes3, Taran Grant4, Edmund D. Brodie III5 & Edmund D. Brodie Jr.6 Tetrodotoxin (TTX), one of the most toxic substances in nature, is present in bacteria, invertebrates, fshes, and amphibians. Marine organisms seem to bioaccumulate TTX from their food or acquire it from symbiotic bacteria, but its origin in amphibians is unclear. Taricha granulosa can exhibit high TTX levels, presumably concentrated in skin poison glands, acting as an agent of selection upon predatory garter snakes (Thamnophis). This co-evolutionary arms race induces variation in T. granulosa TTX levels, from very high to undetectable. Using morphology and biochemistry, we investigated diferences in toxin localization and quality between two populations at the extremes of toxicity. TTX concentration within poison glands is related to the volume of a single cell type in which TTX occurs exclusively in distinctive secretory granules, suggesting a relationship between granule structure and chemical composition. TTX was detected in mucous glands in both populations, contradicting the general understanding that these glands do not secrete defensive chemicals and expanding currently held interpretations of amphibian skin gland functionality. Skin secretions of the two populations difered in low-mass molecules and proteins. Our results demonstrate that interpopulation variation in TTX levels is related to poison gland morphology. Tetrodotoxin (TTX) is one of the most toxic and well-studied but still mysterious natural products.

FAO AdriaMed Project, Rome, Italy * Corresponding author, e-mail: [email protected] This paper presents the first record of the Lessepsian migrant fish Lagocephalus sceleratus (silver-cheeked toadfish) on the Italian side of the south Adriatic Sea. In addition, four specimens of Sphoeroides pachygaster (blunthead puffer) were analysed. Meristic and morphometric data of the silver-cheeked toadfish and blunthead puffer are in accordance with data from the Mediterranean. The specimen of silver-cheeked toadfish was a female with gonad in resting stage and the specimens of blunthead puffer were adults (male and female) with gonads in maturing, mature/spawner and post-spawning stage. The stomach contents of the specimen of silver-cheeked toadfish were composed by Mollusca Opistobranchia and Crustacea Brachyura. Stomach contents analysis of S. pachygaster confirmed that Mollusca are the preferred prey for this species. However, the presence of Crustacea (shrimps, crabs) and fish in the stomachs indicates that the blunthead puffer has a broad and variable diet in the south Adriatic Sea. The present study suggests the presence of an established population of blunthead puffer on the continental shelf of the southeast Adriatic Sea.
