拟除虫菊酯类杀虫剂对养殖甲壳动物毒性影响的研究进展

菊酯是杀灭无脊椎动物害虫的有效成分,具有高效性、广谱性和低毒性等特点,可分为天然菊酯(除虫菊素)和合成菊酯(拟除虫菊酯)[1]。拟除虫菊酯类杀虫剂包括:氯菊酯、氯氰菊酯、溴氰菊酯、氯氟氰菊酯、胺菊酯、氰戊菊酯、醚菊酯、甲氰菊酯等[2]。目前,拟除虫菊酯类杀虫剂的应用范围逐渐扩大。作为开发的新型农药,其被广泛应用于我国农业种植、水产养殖以及相关日常生活用品生产中[3]。随着河流运输和大气沉降等迁移过程.

课程思政融入《甲壳动物增养殖学》教学的探索与实践

在当前教育改革的大背景下,课程思政教育扮演着至关重要的角色,旨在通过专业课程的教学融合思政元素,实现立德树人的根本教育目标。本研究针对《甲壳类动物增养殖学》课程,展开了思政教育与专业教学相结合的实践探索。本文首先梳理了甲壳类动物增养殖学的学科发展脉络,并分析了其在当前中国水产养殖产业中的核心作用。文章进一步详述了该课程的特色和教学策略,特别是如何通过课程内容和结构的创新,有效整合思政元素。通过一系列教学案例的实际应用展示,文章验证了课程思政在促进学生专业能力与社会责任感双重提升方面的有效性。研究发现,有效地将思政教育整合到《甲壳类动物增养殖学》课程中,显著提升了学生的专业理解和批判性思维能力。此外,这种教学方法也成功地强化了学生对社会主义核心价值观的支持和理解,为培养具备问题解决能力和科学方法论的水产养殖行业的优秀从业者提供坚实的基础。Against the backdrop of ongoing educational reforms, ideological and political education in courses plays a crucial role, aiming to integrate ideological elements into professional teaching to achieve the fundamental goal of fostering virtue and educating people. This study focuses on the “Crustacean Aquaculture” course, exploring the integration of ideological and political education with professional teaching. Initially, the paper outlines the developmental history of crustacean aquaculture and its central role in China’s current aquaculture industry. It then details the unique features and teaching strategies of the course, especially on how to effectively integrate ideological elements through innovations in course content and structure. By demonstrating a series of practical teaching cases, the study confirms the effectiveness of course-based ideological and political education in enhancing both professional capabilities and social responsibility among students. The research found that effectively integrating ideological and political education into the “Crustacean Aquaculture” course significantly enhanced students’ understanding of the subject matter and their critical thinking skills. Additionally, this teaching approach successfully reinforced students’ support for and understanding of socialist core values, laying a solid foundation for cultivating outstanding practitioners in the aquaculture industry with strong problem-solving abilities and a scientific approach.

基于劳动教育的《甲壳动物增养殖学》课程教学改革初探

新时代劳动教育是中国特色社会主义教育制度的重要内容,将劳动教育与专业课程相结合是涉农高校教育事业发展的必然要求。为此,本文将劳动教育引入甲壳动物增养殖学课程之中,探索有效的培养模式及课程体系,以培养学生的创造性思维和实践劳动能力,提高学生在专业领域的综合技能和劳动精神,为培养创新应用型人才奠定基础。

七种甲壳类水产品脂肪酸组成的分析研究

水产动物食品中富含ω—3型多稀酸,其中尤其是C_(20:5)(EPA)和C_(22:6)(DHA)对人体有特殊保健功能。本文对七种常见的甲壳类水产品进行脂肪酸组成分析,它们是中国对虾、日本沼虾、安氏白虾、克氏原螫虾、葛氏长臂虾、中华绒螯蟹和三寺疣梭子蟹。测定主要采用黄志斌、李淡秋(1990)的“快速制备脂肪酸甲酯用于气相色谱分析”一文所提供的方法。结果显示,被测样品中不饱和脂肪酸含量高于饱和脂肪酸,而不饱和脂肪酸中多烯酸含量高达60%,且以长碳链(C_(20)、C_(22))ω—3型为特征,表明甲壳类水产品体脂中EPA和DHA含量甚高,超过淡水鱼的一倍,但略逊于海水鱼。值得注意的是,甲壳类水产品中EPA的含量高于DHA的含量,这与鱼类中的情况正好相反。

Investigation and Study on the Alien Species in Aquaculture in the Lower Reaches of the Yangtze River

The lower reaches of the Yangze River is one of the central areas of freshwater shallow lakes in China and has the diverse climates with both warm temperate zone and sub-tropical zone,which makes it become one of the best areas for aquaculture,so nearly all of the aquaculture species from the world can live in the area.It is important for perfecting alien aquaculture species information data-base and environmental risk assessment system to investigate and study the aquaculture alien species in the lower reaches of the Yangze River.The results showed that the number of aquaculture alien species in the lower reaches of the Yangze River is 45 species,including 33 species of fishes,4 species of shellfish,7 species of crustaceans and 1 species of amphibian.Most of alien species are from America and the main transmitting way is intentional introducing.
