Again, just because they can, doesn't mean they should. And the people that wrote those articles are not scientists, nor have been able to properly measure the effects of saltwater on brakish fish, since the environemts are quite different. Using them for quick algae removal may be ok, but put them back in thier brakish natural environment!
Like I said, its not as extreme as my example above, but could lead some people to take such measures.
