I disagree. Including ambiguous names is not helpful, especially where there are unambiguous names that have already been introduced to the reader. The fact that fishermen use other names doesn't mean that we have to in this context. It doesn't make sense to switch from (justifiably) calling it Crangon crangon in one section to "brown shrimp" in another. It significantly reduces the coherence of the whole article. I haven't removed or altered any of the statements you have added, merely reformatted them to fit the context. Feel free to change the section heading, but don't introduce vague terminology where it isn't needed.
