Horse mackerel

The horse mackerel is a fish you catch in the sea. Look for a small shadow. In the northern hemisphere it is around all year, at any time of day. Nook's Cranny pays 150 Bells, C.J. pays 225 Bells.

The most common small sea shadow, around at all hours, all year. You will catch loads, so give three to C.J. for a fish model or sell them for quick pocket money.
