Fish must be specified by type (e.g., Bardiy or otherwise), size (large or small), level of fatness or emaciation, and whether it is fresh (tarri) or salted (milh). The head and tail must not be accepted; only the remaining parts are due. If the quantity is large enough that only a portion is taken, the specific part of the flesh must be mentioned.
