Unless specified (Cod Liver, Salmon etc.) most fish oils come from anchovies. They catch anchovies off the coast of Peru (and similar locations) they are then shipped to their destination (often China) for processing into the oil and softgels. It could potentially be a mixture with other oily fish like mackerel depending on catches.
Oil is rendered from fish by heating, fish oil naturally contains 20-30% Omega-3s (as EPA/DHA).
Most fish oil or Omega-3 softgels come in EE (ethyl ester) or TG (triglyceride) forms. The TG form could be sub-divided into nTG and rTG. Natural TG (nTG) is what we have (and what most people have), this is the oil as it comes from the fish. EE is where it has been processed further, with chemicals, to purify it and make it more concentrated, which is why the EE forms have higher EPA/DHA amounts. The rTG (re-esterified triglyceride) is where the nTG has been processed into EE and then processed back into a TG form again, to make it more “natural” but still more concentrated. Therefore, EE and rTG are not technically natural. Scientific studies have shown very similar benefits from EE and TG forms, so one is not necessarily better than the other.
