| Abstract: | The morphological changes of mitochondria rich cells(MRCS)in gills of juvenile goldfish(Scatophagus argus)were studied by microscopic technique under the stress of sudden salinity drop(20 salinity group put into 5 salinity group)and salinity sudden rise(20 salinity group put into 35 salinity group).The results show that the long and short diameters of MRCs were(9.517±1.390)μm and(7.150±1.448)μm,respectively,significantly higher than those of the control which were(7.317±0.986)μm and(7.317±0.986)μm(P<0.05),respectively;and the MRCs number increased significantly at 6thhour.Two types of MRCs were discovered:Type I MRCs,oval in shape with irregular nuclei,well-developed inner ridges and closed or open apical openings;Type II MRCs,round,with regular round nuclei and multiple apical openings.With different shapes of mitochondria,Type a mitochondria were slightly stained,showing short and thick shape;Type b mitochondria were more deeply stained,showing small granular.The results indicate that juvenile S.argus will produce a response mechanism through the changes of MRCs volume,quantity,shape and structure,as well as the shape and structure of mitochondria in order to maintain the stability of internal environment. |
