If the number of fish is known, they represent women. If their number is unknown, they represent wealth and spoils. Large, fresh fish are spoils and goodness. Small fish indicate worries and sorrows due to their many bones. Whoever sees himself catching a large fish will acquire benefit and goodness. Salted fish indicates worry and grief, or lasting wealth.

Fresh fish is quick, blessed sustenance. Grilled fish is the fulfillment of a need, an answered prayer, or travel in search of knowledge. Eating raw fish indicates attaining a kingdom or marrying a beautiful woman. A fish coming out of the dreamer's mouth indicates a false word and slander he speaks against a woman's honor.
