Body shape changes during the early development of the Beluga (Huso huso)
International Journal of Aquatic Biology, 2013 Early body shape changes of beluga sturgeon were studied using landmark-based geometric morphometric approach to recognize its allometric growth pattern. Sampling was done from hatching up to 50 days post hatching (DPH).

Invisible plastics problem in intensive aquaculture: The case of polyvinylpyrrolidone
Reviews in Aquaculture, Volume 16, Issue 4, Page 1544-1554, September 2024.An emerging contaminant of freshwater ecosystems, the water‐soluble synthetic polymer, polyvinylpyrrolidone, is a biodegradation‐resistant pollutant which may be accumulating within aquaculture systems due to its ubiquitous presence in products used as prophylactic and therapeutic agents to culture aquatic species.
