Red tide effect

[batang_mcdo]

Hi Just wondering,
when feeding our fish with mussels, sometimes there's red tide here, if there's red tide and the mussel is fed to our predatory fish, will this affect our fish? or is this just deadly to humans?

the thought suddenly popped into my mind since i sometimes feed my fish with mussels.
