A Review of the Applications and Challenges of Pulsed Electric Fields in Fish Ecological Protection

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The use of pulsed electric fields (PEF) to regulate fish swimming patterns, especially during migratory channel restoration in dammed rivers, faces significant operational challenges. These challenges can generally be attributed to the multifaceted nature of fish behaviour and limitations in research on physical interception methods.

Biochemical alterations in caged Nile tilapia Oreochromis niloticus

Ecotoxicology and Environmental Safety, 2010
Joinville is an important industrial city in Santa Catarina, southern Brazil, and also a risk factor for the Babitonga drainage basin. Oxidative stress-related parameters were evaluated in caged tilapia (Oreochromis niloticus) exposed for 7 days (sites S1 and S2) in a Babitonga drainage basin tributary river.
