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 ...

THE DIGESTIVE TRACT OF CARASSIUS AURATUS
The Biological Bulletin, 1940 1. The digestive tube of Carassius auratus closely resembles that of Campostoma anonsalum (Rafinesque).2. Study of the gross structure brought out the following characteristics: the posterior pharynx possesses pharyngeal teeth which bite on a dorsal horny pad; a dorsal diverticulum leading to the pneumatic duct extends from the short oesophagus; the ...

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 ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 6, Page 535-544, July 2026.ABSTRACT Stable isotope analysis (SIA) provides essential information toward a better understanding of trophic ecology. However, the interpretation of SIA results relies on assumptions about the trophic discrimination factor (TDF), which aims to improve the accuracy but may lead to bias.
