I reported this issue to Mark Gibson, Deputy Chief of the Rhode Island Dept of Environmental Management. Mark is an expert on Striped Bass biology and management. His comments follow:

"I have been reading a recent scientific paper in the Transactions of the American Fisheries Society by David Secor (vol 137) on "skip spawning" in striped bass and other fish species. It seems that it is not uncommon and is related to longevity. In the case of stripers, it is believed to be due to the energy demands of extensive migrations. Some migrant fish simply decide to conserve energy reserves in some years by not returning to the home rivers. We know of a number of places where striped bass over winter in New England. Those maturing and producing eggs likely will reabsorb them to preserve the energy content. My only concern, shared by Dr. Secor the author, is that we may have overestiimated the reproductive output each year by assuming annual spawning. The ASMFC technical committee is looking at biological reference points this year and will report to the mgt board later this summer. I will make sure they are aware of this most current research.

Mark also asked if I could gather more info on striped bass still with roe - when and where (general). He has already alerted his staff to look for instances of it in their field study. If anyone else has seen this please PM me approximately when they were caught and where( no specifics: just state RI, Mass, New Jersey). I'll compile and pass the info to Mark.

Thanks for any help.
