List of halal and kosher fish

This is a list of fish considered halal according to the Shia Muslims Jafari jurisprudence and kosher according to Jewish kashrut dietary laws. They have the appropriate characteristic of having scales.

Jaafari (Shia) school's regulation of fish comes from several sahih hadiths, one of them is, as narrated by the fifth imam Muhammad al-Baqir:

Eat any fish that has scales, and do not eat what does not have scales.

Sunni jurisprudence generally either holds that all seafood is permissible, with a few minor exceptions (in the Shafi'i, Hanbali, and Maliki schools of jurisprudence), or that all fish is permissible (except eels and hagfish) but other seafood is impermissible (in the Hanafi school of jurisprudence).
