Tamal Roy

Tamal Roy is a Guest Scientist in the Department of Fish Biology, Fisheries and Aquaculture at the Leibniz-Institute of Freshwater Ecology and Biotechnology, Berlin (IGB). His research focuses on the evolutionary and behavioral impacts of size-selective harvesting in aquatic species, particularly through experimental studies on zebrafish (Danio rerio).

Research Interests

Tamal Roy’s work explores how human-induced selective pressures, such as fisheries mortality and harvesting, drive evolutionary and neurochemical changes in aquatic organisms. His research spans behavioral ecology, cognitive science, and evolutionary biology, with a focus on collective behavior, decision-making, and learning mechanisms in zebrafish. Key areas include the effects of size-selective mortality on shoaling dynamics, risk-taking, and social learning.

Publication Trends

His recent publications (2024–2016) reveal a consistent focus on zebrafish as a model organism, investigating how selective harvesting influences behavioral traits across ontogeny and generations. Themes include neurochemical basis of behavior, reproductive isolation, habitat adaptation, and the interplay between environmental factors and cognitive evolution. Collaborations with Robert Arlinghaus and others highlight interdisciplinary approaches integrating ecology, neuroscience, and aquaculture.
