Development and Research Progress of the ‘Land‐Based Container + Ecological Pond’ Recirculating Aquaculture Model in China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review systematically examines China's Land‐based Container + Ecological Pond (LCEP) recirculating aquaculture model. It synthesizes the system's development, technical principles, and research progress, highlighting its significant resource savings (>75% land, >90% water) and high‐density production capabilities. The analysis critically evaluates

Estimation of Parental Abundance Using Hierarchical Bayesian Modeling With Data Augmentation

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Pedigree accumulation estimators leverage the fact that each offspring in a cohort is genotypically “marked” by its parents and represent a recent and promising toolset for estimating population dynamics. We developed a hierarchical Bayesian pedigree accumulation estimator and compared it to previously evaluated non‐parametric approaches.

Novel Assay for Endangered Hong Kong Grouper (Epinephelus akaara) to Assess eDNA Shedding, Decay, and Population Status

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)
