the fish meal from Down To Earth has an NPK of 10-4-0, but their fish bone meal has an NPK of 3-16-0, these two products certainly don't look or smell the same.
i know somebody more qualified than me will chime in, but i would say that fish meal and fish bone meal are not the same thing
check gascan's soil recipe ....... he has both of them in there, so i would think they are not interchangeable.
Two separate products from the same fish....imagine that~
Fish bone replaces mammalian bone meal and fossilized bat guano....as well as the rock phosphates.
Fish meal is like the replacing high nitrogen bat guano or mammalian blood meal.
Mammalian by-products are questionable when it comes to being 'organic' in the common sense of the term.
Not only are they fucking gross...but those animals are exposed to all kinds of funky shit,including regional pesticides,internal pesticides,medications,hormones,etc.,etc,... Just becuase they died doesn't make the blood or bone 'organic'.
There are far better sources than bone and blood....that stuff's just shitty gunky ass by-product.
