Dear Dashiell Gutiérrez

your question is unclear!!

did you mean how you protect certain species of fish from endangering by preserving their DNA?

thanks

I dont know nothing about your work, me like marine biologist...my plan and objective is protect if i can the marine environmental but how i say i dont know nothing about genetic in fishes.... my degree thesis was of ecology of fishes..so please if you can send me you paper and for is an honor read the paper thanks

Im sorry for my english, is not the best but i try speak and write much better...i need improve in english thanks

I graduated since only a month and i working in my english but thats dont meaning that i cant read articles in english, in fact in my thesis i read many scientific articles relationated with my topic...but thanks by the advice....my problem is here when i write and maybe when i talk but less

Dashiell,

you can easily get DNA from fin clip without harming the fish.

Read some Molecular Protocols to learn how this is done.

Best of luck.

Yes, im sorry but i forget that, i remember now because i had the placer of work with an profesor that worked with the tarpon and for DNA analisys, he take samples of the dorsal region of fishes, specifically scales...thanks
