It's been a good CNY fall for getting fish eggs

It’s been a good fall for collecting eggs — salmon and lake trout eggs, that is.
Each fall, the state Department of Conservation Region 7 collects chinook and coho salmon eggs from the Salmon River, as well as lake trout from Cayuga Lake, according to Dan Bishop, regional fisheries manager for the region. The eggs are sanitized, fertilized and then hatched and allowed to grow at one of two state hatcheries.
The salmon fingerlings are eventually stocked in Lake Ontario tributaries, while the lake trout — the so-called Finger Lakes strain — are put into Cayuga and Owasco lakes, along with a few lakes in the western part of the state.
Bishop said workers up at the Salmon River Hatchery in Altmar began collecting chinook salmon eggs on Oct. 8 and finished by Oct. 14. The fish swim right up to the hatchery. The males and females, which die naturally after spawning, are taken in, quickly euthanized and then stripped of eggs and sperm. This year, workers reported taking in 3.34 million eggs.
Hatchery workers began collecting coho salmon eggs on Oct. 15 and finished up this past Tuesday. A total of 1.8 million eggs were taken in. In contrast to the chinooks, the cohos are release back into the river, Bishop said.
Meanwhile, earlier this month, DEC workers on Cayuga Lake took in about a half million lake trout eggs during a three-day period. They used gill nets to capture the fish, which were stripped of eggs and sperm right on the boat. The fish were then released back into the water.
The eggs get fertilized in containers right on the boat and then were taken back to the DEC-run hatchery in Bath, where they’ll be raised for about a year before their release.
