ND salmon anglers asked to turn over fish heads
Share Email Bookmark

The North Dakota Game and Fish Department

is asking salmon anglers to turn over fish heads to the agency so

that tracking information can be retrieved from microscopic tags

embedded in the fish's snouts.

The agency says anglers can tell whether a fish has a coded tag

by looking on its back. If it's missing the small adipose fin in

front of the tail, the fish has a tag.

The agency says some young salmon were tagged before being

stocked in Lake Sakakawea and the Missouri River.

Salmon can't reproduce naturally in Lake Sakakawea, so eggs are

brought to the Garrison Dam National Fish Hatchery and fish are

raised there for stocking.
