INNER BAY OF FUNDY RECOVERY PROGRAM
|
Purpose of Project: Release of mature Atlantic salmon (of Stewiacke River, NS origin) from the live gene bank to contribute to the recovery of the Inner Bay of Fundy salmon population. Adult releases are one component of the recovery process initiated by the Inner Bay of Fundy Planning Committee (IBOFPC). Some salmon were tagged with ultrasonic pingers to determine if they remained in the river until after the normal spawning period. Confirmation of spawning is expected to occur in 2003 and 2004 by looking for juveniles. Tracking juveniles to the adults can be done using genetic information from tissue samples. River of Choice: Outline of tagging study: 2. Ultrasonic pingers were implanted surgically into twelve fish on October 16. 3. Fish released at three locations on October 18:
4. Receiver data downloaded on November 1, 25, 29, and when removed from the river in December. Last receivers were removed on Dec. 14 - 17. Preliminary Results (assuming fish which travel below the lowest
receiver have left the river): 2. One fish stayed in the Irving Pulp Mill pool area until Nov 22, when it travelled downriver and left the river. 3. One fish stayed in the Black Pool area until Nov 13, then it travelled downriver and left the area. 4. Three fish travelled upriver, registering on the uppermost receiver below Kemptown. One of these fish travelled downriver again and registered on the Irving Pulp Mill receiver. 5. Remaining fish registered on receivers throughout the river. 6. No pinger tagged fish registered on receivers placed either in the Black River tributary, the North River or the Cornwallis River. 7. Portable tracking by J. Taylor, Fishery Officer, at various locations, did not locate any fish. 8. Record high rainfall resulted in flood conditions during Nov and Dec before freeze-up. Portable tracking and redd surveys could not be done during this time. One receiver (at John Crowe's) was buried under @ 1/3 m of silt for approximately one week and therefore not recording; one receiver at Irving Pulp Mill was upside down and possibly not recording.
