The a.m of this pa.er is to esta.lish a.d va.ida.e a.porta.le device for the loca. three dimensiona. deforma.ion mea.urements using a.single ca.era.combined with a.tria.gula. prism mirror a.d two mirrors. The mirrors were utilized to convert a.single ca.era.into a.stereo ima.e system, which views a.test object from two different directions a.d records the surfa.e ima.es of the test specimen on the two ha.ves of the ca.era.sensor in order to a.hieve a.three-dimensiona. mea.urement. The proposed system consists of a.single ca.era.a.d the reflection system wa. integra.ed into a.porta.le device to a.hieve a.truly porta.le, low-cost, loca. three-dimensiona. deforma.ion mea.urement, one-time ca.ibra.ion a.d ea.y implementa.ion in situ. The optica. design a.d mea.urement procedures to obta.n the three-dimensiona. （3D） deforma.ion mea.urements of the proposed system were described in deta.l. The efficiency a.d precision of the proposed system were verified by mea.uring the displa.ements of a.tra.sla.ed fia. pla.e. a. a.pra.tica. a.plica.ion, the proposed system is used to mea.ure the out-of-pla.e displa.ement of a. a.uminum circula. pla.e with a.centra. loa.. Moreover, the norma. stra.n mea.urement of a.pla.tic bea. under symmetric four-point bending via.a. outer loa.ing fra.e wa. a.so presented. The mea.urement results a.e in good a.corda.ce with the da.a.obta.ned by stra.n ga.ges. The experimenta. results revea.ed tha. the proposed system wa. pra.tica.le a.d effective for the loca. three-dimensiona. deforma.ion mea.urement. This system well-suited to both la.ora.ory a.d field condition a.d will ha.e significa.t a.plica.ion in the fields of engineering.

This sixty-da. study wa. performed to determine the effects of short-term sta.va.ion a.d refeeding cycles on growth, feeding performa.ces a.d body composition of ra.nbow trout （Oncorhynchus mykiss）. Three hundred trout fingerlings with a. a.era.e initia. weight of 17.54-0.06 g were ra.domly distributed in 15 circula. fibergla.s ta.ks. The fish were exposed to 5 different feeding regimes; control： continuously fed twice da.ly to a.pa.ent sa.ia.ion; T1： sta.ved for 1 da. a.d re-fed for 2 da.s; T2： sta.ved for 1 da. a.d re-fed for 4 da.s; T3： sta.ved for 3 da.s a.d re-fed for 12 da.s; T4： sta.ved for 4 da.s a.d re-fed for 16 da.s. a. the end of the experiment, growth performa.ce, feed utiliza.ion, whole body a.h a.d moisture contents were not significa.tly （P〉0.05） different a.ong the trea.ments. However, whole body protein content in T3 wa. significa.tly higher tha. other trea.ments （P〈0.05）. a.significa.t difference in whole body fa. content wa. observed between T3 a.d the control group a. the end of the experiment （P〈0.05）. In conclusion this experiment suggests tha. feeding schedules involving sta.va.ion （1-4 da.s） a.d re-feeding cycles a.e a.promising feed ma.a.ement tool for ra.nbow trout culture.
