淡水鱼鱼鳞生物结合力与去鳞特性的试验研究

为研究影响淡水鱼去鳞难易程度的因素,以鲤鱼、草鱼、鲫鱼、鳊鱼4种淡水鱼为试验对象,利用TMS-PRO质构仪对鱼鳞与鱼体的生物结合力进行了测量,研究了鱼鳞所处部位、加载速率、死亡时间对鱼鳞生物结合力的影响。同时,测量了淡水鱼单位面积内的鱼鳞数目,淡水鱼的滑动摩擦角,进行了去鳞试验。在此基础上分析并验证了单位面积鱼鳞生物结合力对去鳞的影响,表明淡水鱼单位面积鱼鳞生物结合力越大,去鳞越难,为去鱼鳞设备的研制提供参考。

Study on scale bio-adhesion force and scaling properties for freshwater fish

To study the factors affecting the scaling of freshwater fish, carp, grass carp, crucian carp and silver carp were taken as research objects, and TMS-PRO type texture analyzer was used to measure the bio-adhesion force between fish scales and their bodies. Three factors that influence on the bio-adhesion force of fish scale, including the position of fish scales, the loading rate and the time of death, were studied. Then the number of scales in unit area and friction angles of freshwater fishes were measured, and scaling experiments was conducted. The relationship between the bio-adhesion forces of fish scales and the effect of scaling were analyzed and verified. The results show that scaling of freshwater fish will be more difficult when the bio-adhesion force is bigger. This study can provide a reference for design of scaling device for freshwater fish.
