This document provides an assessment of the Atlantic salmon (Salmo salar L.) stocks of Salmon Fishing Area 18 (SFA 18) of Gulf Nova Scotia. The information includes estimates of fisheries catches and harvests of salmon, estimates of returns and spawning escapements and indices of juvenile abundance. The annual trends in abundance of Atlantic salmon populations in SFA 18 are assessed in relation to past years and to conservation requirements.
This document provides an assessment of the Atlantic salmon (Salmo salar L.) stocks of Salmon Fishing Area 18 of Gulf Nova Scotia. The information includes estimates of fisheries catches and harvests of salmon, estimates of returns and spawning escapements, indices of juvenile abundance, and an analysis of impacts of various fisheries on the Atlantic salmon stocks. The annual trends in abundance of Atlantic salmon populations in SFA 18 are assessed in relation to past years and to conservation requirements.--Document.
The last assessment of stock status for Atlantic Salmon in DFO Gulf Region was completed after the 2013 return year (DFO 2014). DFO Fisheries and Aquaculture Management (FAM) requested an update of the status of the Atlantic Salmon stocks in DFO Gulf Region for 2014. Indicators of abundance for adult and juvenile Atlantic Salmon from the salmon fishing areas of New Brunswick (SFA 15 and 16) are available in DFO (2015). This Science Response Report results from the Science Response Process of March 3, 2015 on Indicators for Atlantic Salmon for Gulf Nova Scotia and Prince Edward Island (SFA 17, 18).
Harry's River is the most northerly of the eight scheduled Atlantic salmon rivers flowing into Bay St. George, Salmon Fishing Area (SFA) 13. The recreational fishery on this river was under quota management until 1995 and the river has been closed to retention angling since 1996. In 1993-95, after the introduction of the commercial fishery moratorium, recreational catches of small salmon remained among the lowest on record but large salmon showed signs of improvement. However, estimates of spawning escapements in those years indicate that the population size of both small and large salmon remained at a low level. This document presents the seventh assessment of the status of the Atlantic salmon stock of Harry's River since 1992. The status of the stock is assessed relative to the conservation requirement based on counts of adult salmon at the counting fence on Pinchgut Brook tributary and spawning surveys of the entire river system.
The status of Atlantic salmon (Salmo salar) stocks of Newfoundland and Labrador was determined using information on annual returns to rivers and spawning escapements relative to conservation requirements, abundance of smolts and trends in marine survival. Overall, of 22 rivers in insular Newfoundland assessed relative to conservation requirements, 14 stocks met or exceeded their requirements, one river was at 65% of conservation, while 7 rivers were at 50% or less than their spawning requirements. Of the latter rivers, three were located in Bay St. George (SFA 13), while three others were enhanced stocks that have been, or are undergoing colonization programs. Some salmon populations continue to remain at low levels of abundance, while others that have experienced increased spawning escapements, have shown no enhanced adult production resulting from this increase in the number of spawners. Marine survival remains low. Limited information from Labrador indicated that while salmon runs were generally low overall, numbers increased over previous years as evidenced by returns to two counting facilities. Factors potentially contributing to low abundance of some stocks and overall poor marine survival are identified along with suggestions as to how some of the factors could be further investigated.
Fifteen separate rivers on the Northumberland Strait shore of Nova Scotia support Atlantic salmon stocks. Stock status information for 1999 is provided for eight of those stocks based on the conservation requirements and escapements calculated either from a mark-and-recapture experiment (River Philip), capture (exploitation) rates in the angling fishery, or a count of fish by snorkel divers (Sutherlands River). Additional information is included for the three principal rivers in the area. East River, Pictou; River Philip and West River, Antigonish.
