Stealth nerf to False Scads?

I have over 75 hours of compiled personal data on how many sands I could get per hour straight farming these from reduction. In the past 2 weeks I have blatantly seen a ridiculous reduction to the catch rate of these fish. Before people start saying "Oh its rng". I have me and another FC member who basically farmed these religiously. For both supplying raid and selling for profit. I have gone from being able to get about 80 MINIMUM/hour to as low as 25-30/hour. This is over 10 hours of collected Data.

Did I miss something in patch notes or was this severely stealth nerfed?

I have had several other friends comment that it seemed to be nerfed compared to the first couple weeks of the expansion. The rate on them isn't bad right now, but you're not alone in noticing this and wondering
