Effects of NaHCO3 Alkalinity Stress on Micropterus salmoides

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT To provide guidance for the actual cultivation of Micropterus salmoides in saline alkali environment, the effects of NaHCO3 alkalinity stress on enzymatic activity, tissue structure and gut microbiota were investigated. The experimental groups consisted of Group 1 (no NaHCO3 added), Group 2 (10 mmol/L NaHCO3 alkalinity) and Group 3 (30 mmol/L ...

Allometric and ontogenetic larval development of common barbel during rearing under optimal conditions

Animal, 2021
The rearing of finfish larvae is a key element in their further culture. Improper breeding protocols may result in high mortality rates, body deformation and growth rate decreases in both the larval and fattening periods.

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Geographic Patterns of Intra‐ and Interspecific Diversity of Riverine Fish Species in the Italian Northern Apennines and Ligurian Alps

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the suitability of environmental DNA (eDNA) metabarcoding to identify inter‐ and intraspecific diversity patterns of riverine fish populations across the Adriatic and Ligurian drainage basins in Northern Italy. Our results revealed genetic as well as community differentiations, with the Adriatic side displaying higher taxon richness ...
