את זה תאכלו מכל אשר במים וגו'. יש קבלה מהבעל שם טוב הקדוש זי"ע במין דגים הנקראים שלייען, או ציגיינר פיש, שלא לאוכלם, שיש עליהם חשש משום שרץ השורץ על הארץ: (עי' דרכי תשובה סי' פ"ג סק"ז בשם אמרי שפר).
This is what you may eat of all that is in the water: You may eat any creature that lives in the water, whether in seas or rivers, that has fins and scales. (Leviticus 11:9) There is a tradition from the Baal Shem Tov not to eat a type of fish called a tench,16Or “gypsy fish” (Tinca tinca). A freshwater game fish of Europe and western Asia noted for its ability to survive outside of water. as there is a concern that it falls under the category of “a swarming thing that swarms on the earth” (ibid. 11:41).17Even though this fish has fins and scales, the signs of a kosher species, its ability to survive on the ground may put into the category of forbidden crawling creatures.
