海产无脊椎动物呼吸强度的比较

对测试的１８种海产经济无脊椎动物的呼吸强度进行的系统比较研究表明：日本和螺类，随时间的延长其呼吸强度呈逐渐下降趋势。说明对氧的含量的敏感性强；而蛤类则随时间的延长其呼吸强度呈逐渐上升趋势，说明对氧的含量的敏感性差．呼吸强度与动物的生活习性有关．习见织纹螺、短滨螺接近陆生生活，呼吸强度最强；日本呼吸强度次之；再次为一般螺类；最弱的为蛤类．

COMPARISONS OF THE RESPIRATORY INTENSITIES OF THE MARINE INVERTEBRATES

Respiratory intensities of 18 kinds of marine inveftebrates are tested, and systematic comparisons and studies make it clear that the respiratory intensities of Charybdis japonica and the Gastropoda tend to fall gradually as time passes, so their sensitivities to oxygen content are more sensitive, and that those of clams tend to ascend gradually as time passes, so their sensitivities to oxygen content are less sensitive. Respiratory intensities of animals are concerned with their living habits and taxonomic status. Nassarius dealbatus and Littorina brevicola are close to land life, and their respiratory intensities are the strongest, Charybdis japonica are higher tardigvada, living in seawater, their respiratory intensities are the secondly strongest, those of the general Gastropoda are the thirdly strongest, and those of the clams are the weakest.
