由于人类对鱼类消费需求的不断增长,世界水产养殖业发展迅猛。2001年,世界人工养鱼产量达3750万t,占世界鱼类产量的30％。2001年,我国鱼产量仍保持世界第一位,达4280万t,其中捕鱼产量为1680万t,养鱼产一为2600万t。世界鱼产量近70％来自中国。目前世界人均年消费鱼16kg,预计2030将将增加至19～21kg。在今后30年内,中国的人均鱼消费量将增长84％。这些数字向人们展示了世界和我国水产业的发展趋势和前景不,这也是本期水产业专辑要为读者输送的信息。 饲料占鱼类养殖中的成本最大,一般点到养殖成本60％～75％。饮料加工工艺对饲料营养价值和水产动物生产性能的影响已愈来愈为饲料工艺学家和动物营养学家所共同关注,本期向读者介绍了“挤压加工技术对全脂大豆在水产饮料中养分消化率的影响”及“膨化工艺对水产饲料营养价值的影响”。“维生素C在鱼类营养与饲料研究中的重要作用及应用”、“甲壳动物软体营养、能量特点及其脂质营养综术”、“几种促摄食物质对南美白对虾摄食行为的影响”、“异育银鲫适宜投喂时间的建立”以及“氧化鱼油营养价值评定”,无疑从鱼类营养需求的角度、从鱼类摄食行为的角度以及从鱼饮料营养价值评定的视角展示了研究的精准与深入、展示了科技的进步与作用,它们将给水产养殖生?
Due to the growing human consumption of fish, the world aquaculture industry is developing rapidly. In 2001, the world’s artificial fish production reached 37.5 million tons, accounting for 30% of the world’s fish production. In 2001, China’s fish production remained the largest in the world, reaching 42.8 million tons, of which 16.8 million tons were for fishing and 26 million tons for fish farming. Nearly 70% of world fish production comes from China. Currently the world’s per capita consumption of fish 16kg, 2030 is expected to increase to 19 ~ 21kg. In the next 30 years, China’s per capita fish consumption will increase by 84%. These figures show people the world and China’s aquaculture development trends and prospects are not, this is the current aquaculture album to send information for readers. Feed accounts for the largest cost of fish farming, the general point of farming costs 60% to 75%. The impact of beverage processing technology on the nutritional value of feed and the performance of aquatic animals has increasingly been of common concern to feed technologists and animal nutritionists. This issue presents readers with an introduction to the topic of “Extrusion Processing Techniques for Full Fat Soybeans in Aquaculture Beverages In nutrient digestibility ”and“ puffing process on aquaculture feed nutritional value. ” “Vitamin C in fish nutrition and feed research in the important role and application of”, “crustacean mollusk nutrition, energy characteristics and lipid nutrition synthesis”, “several kinds of substances to promote food feeding behavior of Penaeus vannamei” , “The establishment of proper feeding time of allogynogenetic crucian carp” and “The evaluation of the nutritional value of oxidized fish oil” undoubtedly show the nutritional value of fish from the perspective of fish feeding behavior and the nutritional value of fish drinks Precision and depth, showing the progress and role of science and technology, they will give aquaculture students?
