Science Beneath the Surface.
Exploring Environmental Impacts on Fish Physiology
We investigate how environmental and human-induced factors shape fish physiology—using advanced molecular techniques and biomarker analysis to drive sustainable aquatic research.
Pioneering research in fish Ecophysiology since 2017.

Prof. Dr. Md. Shahjahan earned BSc Fisheries (Hons.) and MS in Fisheries Management degree from Bangladesh Agricultural University (BAU) with First class First position. He obtained PhD degree under Monbukagakusho scholarship from Kyushu University, Japan in the field of reproductive molecular neuroendocrinology in 2010. Professor Shahjahan completed his postdoctoral research in Niigata University funded by the JSPS of Japanese government. He completed another post-doctoral study at the Monash University with an award by the Australian government.

About Us
Understanding Fish. Advancing Science.
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, heavy metals, and microplastics) 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).
