Someone on a nutrient dense whole food plant-based diet would have no need for bone broth of any sort. Remember that anything from the ocean now comes with heavy metals – mercury, polychlorinated biphenyls (PCBs), other dioxins and plastics! On a risk benefit level, best to avoid consuming anything from the sea. Let them be as scientific studies predict a total collapse of all seafood fisheries by 2050. If the oceans go, so does the planet and our very existence. Get your nutrients from whole plant foods: vegetables including kelp, fruits, beans, whole grains, seeds and nuts.
As for land animal bone broth and risk benefit analysis there is a great concern about high levels of lead. See abstract below with link:
