Damage to Jewish property, verbal abuse, graffiti and antisemitic messages on social media sites were among the reported incidents.
Although the national figures showed a decline, in Manchester there was a slight rise – 81 reported incidents compared to 79 in the first half of last year.
CST spokesman Mark Gardner said: “Any fall in the number of antisemitic incidents that take place is to be welcomed, but we are always wary of reading too much into short-term trends as we know that a lot of hate crime goes unreported.”
