Do they (26 navies in Somalian coast) protect the Somali coast from polluters?

We all know 26 navies (heavily armed to the teeth) are stationed in Somali coast protecting ships passing by, but do they also protect Somali waters from Over-fishers and polluters?

the coast is more than 3000km long, (longest in Africa), do they protect it?
Update 2: I was asking:
If they see a ship and suspect it of polluting, would they arrest them the way they do to the pirates?
or would they let them go?
