The destiny of aquaculture wastes was always a problem to the producers. Besides pollute, they are wastes with high nutritive value. The objective of this research was to produce acid silage using aquaculture wastes. The silage using meiotic acid was elaborated in 16 silos, 4 treatments and 4 replications with 2.000 g of grinded fish/silo and respectively 150, 200, 300 and 350 ml acid/treatment, during 3 weeks. The pH was diary accompanied. Total Count of Microorganisms and Total Coliforms analysis was realized after 1 and 3 weeks and Coliforms at 45ºC after 3 weeks. These analysis determinate low bacteria concentration and absence of Coliforms at 45ºC, changing the product adequate to animal feed.
