Effects of different photoperiods on the survival and growth of beluga sturgeon (huso huso) larvae
International Journal of Aquatic Biology, 2013 Effect of different photoperiodic regimes was evaluated on growth performance and survival rate of the Beluga (Huso huso) prelarvae and larvae. Newly hatched prelarvae were stored in 5 round fiberglass 500‑L tank with different photoperiod (24L:00D, 18L ...

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).

Journal of Fish Biology, Volume 105, Issue 3, Page 735-751, September 2024.Abstract The ontogenetic development in teleost fish is sensitive to temperature, and the developmental rate has a direct relationship with the environmental temperature within a species' thermal tolerance limit. Temperature determines time to and survival at hatching.

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.
