Dear Aspirant,

As mentioned by you, you can utilise the academic journals & websites on the internet like Researchgate, Academia etc. There are numerous people out there who put out their research in terms of pdf documents. To go one step ahead, you can also contact the author of the articles via email communication & look out for help. I'd suggest you to search the academic journals for the research of "Zebrafish".

Thanks for visiting this site. Hope it helped.
