The answer may be in what you are not seeing. For example, if the LMB are currently lower RW than 30 days ago, what was present then that isn't now? What were they eating, proportionate size wise, that helped them be RW 150s, that isn't available now because they were eaten. One possibility on your BG question may lie in which forage grows faster. For example, if BG grow slower (not saying they do), wouldn't they be more vulnerable to predation? Predation may be the culprit for seeing fewer of them as you suspected above. There are lots of ways to look at things like this but it is always good to flip the coin and examine the other side. In the end, LMB eat what they can and all they can. Its probably a matter of can at the moment. When the TP begin declining due to colder water. This will redefine what can be eaten on the TP side of things. Should be a buffet going on if they stay pretty much the length they are now.
