In the fall, some areas of the Miramichi River may not be accessible to the wild adult salmon that typically spawn there. This can be due to low water levels or impediments such as beaver dams. As well, survivability may be especially low in parts of the river due to reasons like competition for resources. Stocking programs can help boost salmon populations by adding juvenile fish to these low-density areas of the river.

Fry stocking on the Miramichi River has been happening for over 150 years. During its early years, the Miramichi Fish Hatchery, now known as the Miramichi Salmon Conservation Centre, would purchase live adult Atlantic Salmon from commercial trapnet fisherman to use as broodstock for spawning and fry-stocking. Without motorized vehicles, fish had to be transported in tanks of water by horse and wagon, boat, or train. Since 2004, the MSA has stocked over 3.8 million salmon fry in the Miramichi River – over 1.4 million on the Northwest branch and over 2.4 million on the Southwest branch. These fry have been distributed to over 950 sites in the Miramichi watershed - 300+ sites on the Northwest and 600+ sites on the Southwest.

Salmon are collected from the Miramichi River and kept at the hatchery until they are ready to spawn. After spawning, the live fish are released back to the river. The fertilized eggs are kept in incubation all winter until the fry hatch the following spring. These fry are then stocked back into the waterways their parents came from (natal streams). In the wild, less than 30% of eggs hatch and survive to become fry, but in the hatchery we can increase this rate of survival to 80-90% thanks to continuous monitoring and good husbandry practices. The eggs experience no predation or gouging ice flows that may kill the wild redds (piles of eggs buried in the gravel after spawning).

The number of fry to be stocked is estimated by calculating the group's weight. Estimating the number of fry to be stocked helps us manage fry densities when transporting them and stocking them in their natal water, ensuring we maximize their survival. When the fry are ready to leave the hatchery and return to the river, they are placed in oxygenated water tanks on the back of trucks. The MSA staff then use buckets to carry the fry to the river for release. Later, these release sites are surveyed via electrofishing to gauge the success of stocking activities.

Traditional fry stocking techniques involve spawning adult broodstock salmon, however the MSA also carries out DFO-approved research studies on novel fry stocking strategies to determine the best stocking strategies for our watershed. Annual and long-term studies on stocking strategies are valuable to river conservation world-wide.

2022 Stocking Report

Stocking Atlantic salmon (Salmo salar) first-feeding fry can improve the juvenile production capacity of the Miramichi River by targeting areas that are under-seeded or inaccessible to wild spawning adults. An electrofishing survey is carried out each year by the Miramichi Salmon Association (MSA) to assess areas of the river that are lacking adequate numbers of fry or parr. Low fry or parr numbers could be the result of multiple factors including poor adult returns, barriers to adult movement into upper stream reaches (i.e.: beaver dams), environmental events such as ice scouring that could destroy a redd, or suboptimal water conditions. Areas with zero/minimal fry present were targeted to stock and efforts were made …

2020 Stocking Report

Approximately 88,156 first-feeding Atlantic salmon fry were stocked into 17 sites in four tributaries of the Miramichi River (Figures 1a&b, Figure 2). The Northwest Miramichi River received 23,567 wild fry (Table 1a) and the Northwest Millstream 30,118 SAS fry (Table 1b). The Southwest Miramichi River system received 34,471 wild fry – 9,853 in Burnthill and 24,618 in Juniper (Table 2). The water levels were very low this summer and a fire ban was in place to keep vehicles out of the woods during our stocking days, so some sites had additional buckets of fry added due to lack of available and accessible habitat. A further 12,766 brook trout fry were distributed to a satellite tank rearing location for future release (Table 3).  ...
