  • 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.

  • Takifugu Niphobles
    Joseph Fratello Marine Biology Professor Tudge 10/16/17 Takifugu niphobles Introduction: The Takifugu niphobles or ​ ​ ​ the Grass Puffer is a small fish that resides in the shallow waters of the Northwest Pacific Ocean. The scientific name of the fish comes from the japanese words of taki meaning waterfall and fugu meaning venomous fish (Torres, Armi G., et al). The Takifugu niphobles is part of the ​ ​ family Tetraodontidae which encompasses all puffer fish and are known for their ability to inflate like a balloon. The fish do this by quickly sucking water into their stomachs causing them to inflate and causing the flat lying spines which cover their bodies to become erect. Their diets consist of a wide array of small crustaceans and mollusks (Practical Fishkeeping, 2010). Takifugu ​ niphobles are one of the two most common fish in the Northwest Pacific Ocean and are ​ often accidently caught by fishermen who employ the bottom longline technique (Shao K, et al., 2014). The sale of these fish, including other puffers, are banned in japanese markets due to their highly toxic nature. Yet, puffer fish are considered a japanese delicacy despite the fact that a wrong cut of meat can kill a fully grown man. Upwards of thirty to fifty people are affected by the toxin every year and chefs must undergo two years of training before they can legally sell the fish (Dan Bloom 2015). These fish have a very unique means of reproduction, in which they swim towards the shore and lay their eggs on the beach. The fish then, with the help of the waves, beach themselves and fertilize these eggs.

World-wide there are few countries in which pufferfish (fugu) is eaten as in Japan. In Vietnam, pufferfish has been banned since it’s toxic ocurred due to lack of knowledge about distinguish non-toxic species. Consequently, there is a huge amount of pufferfish inhabiting in Vietnamese water, but whenever accidentally catching it, we have to throw or use as fertilizer. To develop culinary culture of non-toxic pufferfish in Vietnam, it is very important and essential to recognize safe species and culture them in good condition, then apply proper method to process that become safety foods. In order to initial setting up for such purpose, we carried out a sensory study in Vietnamese to test whether they can accept foods made from fugu by method of Japanese. Methods. We compared the sensory reaction to Japanese cultured Takifugu rubripes and fish from Vietnamese waters: grouper and mackerel. The 107 panelists were Vietnamese volunteers working in the field of nutrition, employees of marine companies, or government officials who could influence the relevant laws.

Page 1/20 Abstract Background The mechanism of osmoregulation is crucial for maintaining growth, development, and life activities in teleosts. Takifugu obscurus, the only euryhaline species in the genus Takifugu, is a proper model organism for studying the mechanism of low salt-tolerance and hypoosmotic regulation. Results In this study, whole genome sequencing data were obtained from 90 puffersh representing ve species within this genus, T. rubripes, T. obscurus, T.
