| 摘 要： | 2015年6-9月期间,对青岛市宝荣水产科技有限公司凡纳滨对虾(Litopenaeus vannamei)工厂化养殖车间的6个实验池进行采样调查,分析了水体中微藻的种类组成、丰度、多样性和优势种演替特征,并结合养殖情况进行了讨论.共检出微藻5门28属49种(其中优势种14种),丰度范围为5.2×105-9.4×108 cell/L,生物量范围为1.23-208.00 mg/L,多样性指数范围为0.42-2.44.多样性指数低于0.9时,生态系统稳定性差,对虾易发病.不同养殖阶段微藻优势种种类不同,前期主要是绿藻门(Chlorophyta)、硅藻门(Bacillarionphyta)和部分甲藻门(Pyrrophyta)的种类,中、后期以蓝藻门(Cyanophyta)的微囊藻(Microcystis sp.)和颤藻(Oscillatoria sp.)为主.对虾养殖密度显著影响微藻优势种演替,300 ind/m2养殖密度(A1池)藻相稳定且以绿藻和硅藻为优势种,对虾生长良好;400-500 ind/m2养殖密度(B1、C1和C2池)颤藻在中、后期演替成为绝对优势种,对虾易发病死亡.本研究为优化对虾工厂化养殖环境、指导养殖生产提供参考.

| Abstract: | The microalga community in 6 industrial aquaculture ponds of Pacific white shrimp (Litopenaeus vannamei) was analyzed at Baorong Aquatic Science and Technology Limited Corporation in Qingdao from June to September in 2015.The composition of species,abundance,biodiversity and characteristics of dominant species succession were investigated and discussed based on the situation of shrimp culture.A total of 49 species of microalgae were identified that belonged to 28 genera and 5 phylums (including 14 dominant species).The population density of microalgae was 5.2 × 105-9.4 × 108 cell/L,the biomass was 1.23-208.00 mg/L,and the biodiversity index was 0.42-2.44.The stability of the ecosystem was weak and the shrimps were prone to outbreaks of diseases when the biodiversity index was below 0.9.The dominant species in the early stage of cultivation were green algae,diatoms and some species of dinoflagellates.Microcystis incerta and Oscillatoria willei belonging to Cyanophyta gradually became the dominant species in the middle to late stages.The culture density of shrimp had significant effects on the succession of microalga dominant species.The shrimp grew well in a stable community of microalgae where the culture density was 300 ind/m2 (pond A1) and the dominant species were mainly green algae and diatoms.The harmful Oscillatorias tended to become the dominant species in the middle to late stages as the culture density was 400-500 ind/m2 (in pond B1,C1 and C2),which easily led to the outbreak of shrimp diseases.Our study provided important information on the tuning of the environment of industrial aquaculture ponds. |
