Fish oil is a broad term and is not the same as krill oil. It could mean cod liver oil and other things. I think you're thinking of Omega-3 fatty acid supplements (which are usually derived from fish) VS. Omega-3 fatty acid supplements derived from krill. The ones from krill are more absorbable/bioavailable/potent than the ones from fish. That's the only real difference. On average instead of taking 3 large softgels of Omega-3 (which is from fish) you could take just 1 medium softgel of krill-derived Omega-3 which is a lesser dose, but the bioavailability to your body will be equivalent just the same.
It might help for ADHD for some people but I wouldn't expect the results to be so dramatic unless you combine it with other dietary supplements. For ADHD I advocate trying a Dr. Marty Hinz-based regimen:
Take once daily with a meal:
- 500 mg tryptophan
- 500 mg tyrosine
- 100 mg 5-HTP
- 100 mg L-DOPA
- 200 mg SAMe
My regimen is FAAAR from dangerous/irresponsible. I've even tried it myself personally several times. I would never recommend something that could endanger one's health. Here is the research it's based on: http://www.neuroscie...z-and-stein.htm They have had success in treating all kinds of maladies/ailments by providing a unique formulation of those 5 factors concomitantly as a daily regimen for people. Please consider removing the dangerous/irresponsible flag on my post above. 
Stacking seratonin and dopamine precursors sounds pretty irresponsible to me. Why would you need 5htp and tryptophan? Why would seratonin help someone with add? I understand the dopamine logic for that, but there are far better options for nootropics than this, like magnesium for example.
It's not at all irresponsible. This is why I have provided a link to all the research but I find that you're still asking questions that are answered on the website I have provided. Here is a concrete example of a research study dedicated to ADHD whereby 85 human subjects were provided a regimen similar to the one I have provided as stated in my original post; a Dr. Marty Hinz-based regimen: http://www.ncbi.nlm....les/PMC3035600/
The research does not prove how it works, but for someone like me it's rather obvious: since dopaminergic neurons can affect serotonergic neurons and vice versa, the strategy here is to strengthen the innate neuronal physiology for cognition by exploiting neuroplasticity, so that one can stay focussed rather than having random thoughts cause their cognition to stray from the current thought. Supplementing concomitantly in this way, elevates innate levels of serotonin & dopamine neurotransmitters for a temporary boost in neuronal firing while alleviating ADHD symptoms via a more solid cognition. Then, as signals pass through neuronal bundles, neuroplasticity reinforces these pathways by having dendrites reach out to other neurons and improve the function of each bundle, so that chronically the physiology of the brain is bolder in terms of establishing a cohesive mindset that can stay focussed. According to Hinz's research, if a person supplements just one of the amino acids or precursors I have specified, they will cause a reduction in neurotransmitter levels of the other (dopamine VS. serotonin), so not taking all of those concomitantly with a methyl donor would be detrimental for one's prognosis of their malady.
