一体化的发展,生理学和水生无脊椎动物对环境变化的反应

水生无脊椎动物,尤其是软体动物和甲壳类动物,是一个非常大的生物。许多种类的贝类和甲壳类动物有很大的经济和食品价值,因此世界各地广泛养殖。然而,研究贝类和甲壳类动物脊椎动物相比仍远未足够。具体来说,贝类和甲壳类动物的研究进展主要有以下问题:(1)底层知识生殖内分泌调控机制和软体动物和甲壳类动物卵巢发展尚不清楚。此外,研究贝类和甲壳类动物本身是否能合成类固醇激素和类固醇激素的作用机制仍在起步阶段。(2)大多数贝类和甲壳类动物是性二态的,也就是说,女性和男性表现出显著差异在经济增长率等特征,个体大小和质量。因此,探索在贝类和甲壳类动物的性别决定和分化机制具有重要意义,指导经济的单性繁殖的物种。(3)提高水产养殖的规模经济贝类和甲壳类动物和不成熟的市场,一些贝类和甲壳类动物种质资源退化的现象。因此,迫切需要开展贝类和甲壳类动物的种质资源评价和新品种的选择。此外,甲壳类和贝类的养殖模式仍处于相对低的水平,并有必要创新农业模式。 (4) Recently, on the one hand, the construction of marine engineering has reduced the living and breeding space of marine organisms, resulting in a decrease in their aquaculture production; on the other hand, the pollution of the marine ecological environment leads to eutrophication of water bodies and the proliferation of algae, which affects the respiration of shellfish and eventually leads to the death of shellfish. Understanding the response mechanisms of shellfish and crustaceans to adverse environments can provide basic information for the cultivation and protection of shellfish resources. In addition, as an important part of marine pollution biomes, bivalve mollusks also have high ecological value. Therefore, it is of great significance to carry out the classification and ecological research of shellfish for the subsequent classification and identification, ecological investigation and control. (5) As a filter-feeding species, shellfish need to feed a large number of live algae in the process of artificial breeding, which greatly increases the cost of breeding. Furthermore, the lack of commercial farmed feeds limits the scale of farming of most shellfish. Therefore, the research on the nutritional requirements of filter-feeding shellfish and compound feed has strong application value. In addition, shellfish and crustaceans will be infested by various pathogenic bacteria during the breeding process, and due to the particularity of their living environment, once the disease occurs, its treatment is more difficult. Therefore, understanding the pathogenic mechanism of its disease is very important for the innovation of disease control technology in the breeding process.
