Not good. Keep in mind total numbers collected is a bottom trawl survey. If conditions exist that favor alewives suspending, they won’t be collected. The acoustic survey may shed more light. However, it stands to reason more predators= less prey. The three year old year class of kings is exceptional.
The large class of kings everyone will be catching are three years old this year. Yes, they will start egg formation now. Empty stomachs this time of year is not abnormal on a late spring. Most of the alewives are still on the bottom in 400'+ feet of water. Alewives did not start on the bottom, they slowly move there over the course of the winter because warmer water and Mysis zooplankton are found there. Younger class of kings are not suited for 400' of water. More likely they are feeding on the suspended bait 150'-250' over the winter. As more and more bait heads to the bottom, there is a time period when kings are running out of food and go looking- ending up along the shore in time for the spring inshore migration of alewives to begin. Adult alewives are coming into the Niagara, Genny and Oswego river flows along the bottom, hit the bank, find warmer water, then begin to populate the upper warming layers of the water column that is developing inside of 100'. This is the normal pattern. What is not normal is the size of this year class of kings and the effect on bait levels. The early-in from last year and this year is they are having a negative effect on alewife populations based on trawler surveys. Do not hesitate to keep your kings for the barbecue this year. Next year.......that is another story- lots of cormorants have me worried about king numbers.
My concern is they will return to the salmon river and end up back at the hatchery. The fish I have seen with the condition appear healthy and functional. I worry about the ones we don’t see that die in the system.
Since we are seeing gill plate rot with more frequency, I think as a group collectively we should consider keeping these fish and getting them out of the system. Thoughts?
