Aircraft X was being vectored for the RNAV RWY 29R approach. I gave Aircraft X a vector and altitude to maintain until established on the final approach course. The altitude was at 3;400. That is the lowest altitude available with the current MVA [Minimum Vectoring Altitude] in that area. As Aircraft X was descending for the crossing fix; Aircraft X was descending through 3;400. I asked the pilot if he blew through his altitude. The pilot stated he was descending to 3;000. I reviewed the tapes and the pilot read back 3;400.Hear-back/read-back error.
FAT TRACON Controller reported that an aircraft descended through the assigned altitude and below the MVA.
