Decoding Aquaculture's Future: A Review of Molecular Docking and Simulation in Enhancing Growth and Disease Resistance

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Aquaculture has overtaken capture fisheries as the main source of aquatic animal protein, marking a critical step in global food security. Yet, rapid intensification faces major challenges, including disease outbreaks, environmental degradation, and dependence on wild‐caught fish for feed.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Feminisasi Nila (GIFT), Oreochromis sp. Menggunakan Hormon Estradiol 17-β

Jurnal Perikanan Universitas Gadjah Mada, 2006
Research to find out the effect of oral administration of estradiol 17-β  on feminization of Oreochromis sp. (GIFT) fry was carried out at Cibalagung Research Station. Five different concentrations of estradiol 17-β  i.e.: 60, 80, 100, 120 and 0 mg/kg feed, were given to larvae of 6 days old twice a day for 21 days in triplicates.
