Some have also begun using non-wood materials, such as plastic or graphite.

Some also banned fishing for some time each year.

Some also block or partially block serotonin receptors ( particularly 5HT < sub > 2A, C </ sub > and 5HT < sub > 1A </ sub > receptors ): ranging from risperidone, which acts overwhelmingly on serotonin receptors, to amisulpride, which has no serotonergic activity.
