Is River Water Reducing Our Trout Spawning Season??

Went yesterday for a Catch & Release day , decided to keep 6 trout to cook for lunch, noticed that on all 6 trout that the egg sacks were very little small, couldn’t detect any eggs at all! Has any body else noticed this in there catch ? Would like to get a Opinion on this subject! I know that trout need saltier water to spawn in, water around Lake Robin tastes to fresh !!

Caught 4 out of Trade Winds yesterday up in the marsh 13 - 16 inches...2 that had eggs like those maybe less , the other 2 had eggs that were a pale yellow...

Fished Leeville west Thursday and caught a limit. All were females but 2 of them. The smaller ones had small but decent eggs in sac and the larger trout had nice full ones. Water was quiet salty. I’m sure fresh water really hurting stock.

Wizard,It seems like those egg sacs were a tad on the smallish side and when Buddy,Dane,and I cleaned our fish from this past Monday plenty of females in the box had egg sacs like those,not great news as they need saltier water to lay those eggs in and if they lay eggs in water not salty enough,the eggs do not survive.Think they need somewhere around 12-14 parts per thousand in order to survive and seriously doubt the water anywhere near where those fish caught close to that level.What was perplexing is that we saw plenty worms in specks,somewhat confusing since the saltier the water,the more prevalent the worms are!!When Lady P was giving up nice specks,seems like decades ago,rarely did I find worms in Lady P specks.Wish the River would get dredged much deeper,possibly allowing less than annual Spillway Openings!!!Hope to get down there next Tues and Th!!

The water is fresh way past lake robin. I doubt the river water is changing spawning dates as much as it is displacing spawning activity. Females that are ready to spawn will seek saltier water to spawn which right now might be all the way to the chandeleur islands so if you are fishing in fresh water you probably won't have a lot of roe to fry for lunch. In normal years I see this; on trips to the rocks ect. we get good roe from the females whereas the trout we catch close to the launch in fresher water don't have well developed ovaries. Likely they go out to spawn then come back to fatten up for the next round of spawning on the inside where there is more food and less things trying to eat them but I'm not sure any of the tracking data has proven that. The question is with the spawn displaced so far to the outside two years in a row how will that affect the number of juvenile trout returning to the marsh??? In the past research indicated that the increase in forage base associated with the influx of nutrient rich river water offset poor recruitment with faster growth rates but with two full years of very low salinities who knows.

Guess only time will tell and an educated guess would be that the areas in question will see serious reduction in juvenile,hence keeper-sized specks in next few years and areas on the ouside,saltier habitats,will see nice increases in keeper-sized specks.Anyway one looks at it,not pleasant and if these Spillway Openings on annual and sometimes bi-annual basis continues,no doubt oyster harvests gonna go way,way down and the St.Bernard brackish marsh may be permanently altered.How about the prospect of Asian carp instead of redfish???Not good thought but gotta report de good with the bad!!!Hope to chase some marsh fish next Tues/Th and if winds not conducive,might just opt for Th marsh trip!

Don't think it will get that fresh but if it does we can fish sacalait on the causeway. I think the days of catching trout in the western lake in the summer are coming to a close but that was always an artificial circumstance wrought by the MRGO. I doubt back to back spillway openings will be the norm let alone double openings but a much less saline inner estuary will. You just have to adapt with it; I would never have thought 20 years ago that we would catch bass in Pisana routinely but then again in the 1950's likely no thought there would ever be a time when there WERE NOT bass there. Fishing on the east bank will be more like fishing Venice in the future I would think, sans getting crushed by cargo ships, it will take more effort to figure out but there will be more options.
