Again, there are two conditions that must be met at the same time: a water animal ought to have both fins and scales to be kosher. This means that Jews can enjoy many popular fish species, such as herring, salmon, cod, tuna or pike. One should be careful with carp, as some varieties have no or very few scales. Some rabbis have specified that a fish must have at least three scalesto be kosher, although most agree that one scale is enough as long as one is certain that the scale actually belongs to the fish and didn't just stick to its skin after detaching from a fish of a different species.<ref>{{Cyt
