【目的】松江鲈(Trachidermus fasciatus)是国家二级保护动物,属于广盐性的洄游性鱼类。研究松江鲈增殖放流前适宜的淡化模式。【方法】采用组织切片技术对急性淡水胁迫、不同淡化速度(每次降低5个盐度,并每12、24、48 h降低1次,记为A、B、C组),以及不同淡化幅度(每24 h降低1次,并每次降低2、3、5个盐度,记为D、E、B组)下松江鲈幼鱼鳃的显微结构变化进行研究。【结果】将处于盐度25的松江鲈幼鱼直接放入淡水中进行急性淡水胁迫,1 h时,鳃组织结构形态正常;12 h时,鳃丝出现表皮轻微脱落;24 h时,血细胞出现吸水胀破现象;3 d时,鳃丝和鳃小片的空泡数量显著增多;7 d时,鳃丝和鳃小片表皮脱落最为严重,鳃小片长度增加而宽度减少、末端弯曲,出现细胞溶解现象,形状不规则,空泡除在鳃小片基部出现外、位置也有所上升,血细胞数量减少,线粒体丰富细胞数量增多。盐度25时,A~C组鳃组织结构无明显变化。盐度降至15时,A组鳃丝结构破损现象较其他两组明显。盐度达淡水时,A组鳃组织结构破损严重,鳃小片长度增加但宽度减少,结构不完整,线粒体丰富细胞数量增多,血细胞数量较盐度15时减少;A组鳃丝和鳃小片结构较B、C组有明显差异,不完整程度更严重,B组和C组之间差异不明显,鳃组织结构破损程度相近。起始盐度25,淡水驯化1 h时,D、E组和B组之间的鳃组织结构差异不明显;12 h时,3组鳃组织中空泡数量增多;24 h时,B组和D组鳃中的空泡数量比E组多;3 d时,B组鳃组织较其他两组脱落区域更多;7 d时,E组线粒体丰富细胞及血细胞数量比B、D组多;B组鳃组织结构的不完整程度比D、E组更严重。【结论】随淡水驯化时间增加,松江鲈通过增加鳃小片长度,控制血细胞、线粒体丰富细胞数量等提高自身渗透能力,减少胁迫对鳃的危害。此外,降低淡化速度和幅度有助于松江鲈更好地适应盐度变化,建议选择每日降低2个盐度的淡化模式,以减轻淡水驯化对松江鲈鳃组织结构的损害。

BiFeO_3 (BFO) thin films with BaTiO_3 (BTO) or SrTiO_3 (STO) as buffer layer were epitaxially grown on SrRuO_3-covered SrTiO_3 substrates. X-ray diffraction measurements show that the BTO buffer causes tensile strain in the BFO films, whereas the STO buffer causes compressive strain. Different ferroelectric domain structures caused by these two strain statuses are revealed by piezoelectric force microscopy. Electrical and magnetical measurements show that the tensile-strained BFO/BTO samples have reduced leakage current and large ferroelectric polarization and magnetization, compared with compressively strained BFO/STO. These results demonstrate that the electrical and magnetical properties of BFO thin films can be artificially modified by using a buffer layer.
