Without checking the assumptions / BOTEC in detail, I’ll just flag that this implies you are indifferent between saving 1 human life (not just averting 1 malaria death) and helping ~1000-1900 shrimp die via electrical stunning instead of dying via air asphyxiation / ice slurry.[1]
Thanks for the note, Bruce. Your estimate makes sense. Based on GiveWell’s implicit valuation of saving a life of 51 DALY/life[1], and my 0.0288 DALYs averted per shrimp helped, helping 1.77 k (= 51⁄0.0288) shrimp is as good as saving a life.
According to OP, “GiveWell uses moral weights for child deaths that would be consistent with assuming 51 years of foregone life in the DALY framework (though that is not how they reach the conclusion)”.

(This is not an anti-SWP comment tbc!)
Depending on whether you are using $3000 to $5500 per life saved;
15000 * 3000 / 43500 = 1034.5
15000 * 5500 / 43500 = 1896.6
