Histological effects of Cu2+ to white shrimp Litopenaeus vannamei (Crustacea: Decapoda) juveniles at low salinities
Juveniles of the white shrimp Litopenaeus vannamei were exposed during 25 days to the Cu2+ concentration commonly used in Mexican shrimp farms, at salinities of 1, 5, and 10 psu, in order to observe possible histological alterations to the antennal glands, midgut, gills and hepatopancreas. Survival...
