The Laboratory of Fish Ecophysiology was established in 2017 by Prof. Dr. Md Shahjahan. The primary focus of the lab is to analyze the impacts of environmental factors (such as temperature, light, and salinity) and anthropogenic factors (such as pesticides and heavy metals) on fish physiology, particularly in relation to growth and reproduction.

Physiological parameters of blood are used as biomarkers, alongside molecular techniques like real-time PCR. The lab is equipped with several experimental ponds and a wet laboratory, where fish are reared and treated in various sizes of aquaria and cemented tanks.

Model experimental species include zebrafish (Danio rerio), Nile tilapia (Oreochromis niloticus), Indian major carp rohu (Labeo rohita), striped catfish (Pangasianodon hypophthalmus), and common carp (Cyprinus carpio).
