Dietary Tea Polyphenols Improve Growth Performance, Physiological Health and Economic Efficiency in Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Tea polyphenols (TPs) are natural bioactive compounds extensively used in aquaculture diets as a functional supplement because of their antioxidant, antimicrobial and immunomodulatory potential. Four isonitrogenous diets (crude protein: 30%) were designed with incorporating TPs at levels of 0% (control, TPs‐0), 0.025% (TPs‐1), 0.05% (TPs‐2 ...

Haematology of gynogenetic diploids of Siberian sturgeon Acipenser baerii Brandt [PDF]

Acta Veterinaria Brno, 2013
Haematological analyses were conducted in gynogenetic diploids and control diploids of Siberian sturgeon ( Acipenser baerii ). Gynogenetic diploid fish were obtained from Polish aquaculture after induction of meiotic gynogenesis based on application of UV-irradiated hybrid Siberian sturgeon ×

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, Volume 109, Issue 2, Page 864-884, August 2026.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Outbreak of mortality in Russian (Acipenser gueldenstaedtii) and Siberian (Acipenser baerii) sturgeons associated with sturgeon nucleo-cytoplasmatic large DNA virus [PDF]

, 2016
Diseased outbreaks with high mortality in farmed sturgeon are a limiting factor to the success of this emerging aquaculture sector in Europe. Thorough investigations of outbreaks can determine the aetiological agents, identify important pathological and ...

High‐throughput multispecies quantitative polymerase chain reaction assays to study the effects of acute thermal stress in three species of Acipenser sturgeon

Journal of Fish Biology, Volume 109, Issue 2, Page 899-914, August 2026.
Abstract Fishes experience thermal stress in their natural environment that can be caused by natural or anthropogenic factors and can directly affect their physiology. In this study, we developed a multispecies OpenArray™ qPCR (quantitative polymerase chain reaction) ‘chip’ to measure the effects of acute thermal stress on the mRNA response of ...

Bioaccumulation of heavy metals, Ni, Cd and Pb in muscle, liver and caviar of farmed Acipenser baerii from Khuozestan Province

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2017
The presence of heavy metals in our environment has been of great concern because of their toxicity when their concentration is more than the permissible level. These metals enter in the environment by different ways e.g. industrial activities.

Growth and histomorphological responses of Chindongo socolofi to the long‐term replacement of fish meal with defatted Tenebrio molitor meal

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The long‐term suitability of defatted Tenebrio molitor larvae meal (TM) as a substitute for fish meal (FM) protein was evaluated in Chindongo socolofi over a 170‐day feeding period. Six isonitrogenous (38% crude protein) and isoenergetic (4396 kcal kg−1) diets were formulated, in which TM protein replaced FM protein at 0% (control), 20%, 40 ...
