Morphology and Distribution of Olfactory Receptor Neurons in Southern Bluefin Tuna, Thunnus maccoyii (Teleostei): Implications for Olfactory Hydrodynamics

open access: yesJournal of Morphology, Volume 287, Issue 5, May 2026.
The number and distribution of olfactory receptors over the olfactory lamellar surface of four juvenile southern bluefin tuna were quantified using scanning electron microscopy. The microvillous olfactory receptors (mORN) are concentrated in the rostral region of the lamellar surface, while ciliated olfactory receptors (cORN), which are dominant in ...

Variation in the food intake of grass carp, Ctenopharyngodon idella (Val.), fed singly or in groups [PDF]

open access: yes, 1992
Each animal may be assumed to possess a unique combination of physiological traits (Bennett, 1987). However, there is little information on thc effects of interindividual variation in fish (Cui and Liu, 1990).

Effects of NaHCO3 Alkalinity Stress on Micropterus salmoides

open access: yesAquaculture, 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 ...

Clustering pattern and evolution characteristic of microRNAs in grass carp (Ctenopharyngodon Idella)

open access: yesBMC Genomics, 2022
Abstract Background A considerable fraction of miRNAs are highly conserved, and certain miRNAs correspond to genomic clusters. The clustering of microRNAs can be advantageous, possibly by allowing coordinated expression. However, little is known about the evolutionary forces responsible for the loss and acquisition of microRNA and microRNA ...

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Dietary Probiotics Improve Growth, Immunity and Disease Resistance in Fish Against Aeromonas hydrophila Infection

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Probiotics offer a promising alternative to antibiotics for managing Aeromonas hydrophila infections in aquaculture. Dietary supplementation of probiotics increases fish health, growth performance, and immune responses, while reducing antibiotic reliance in fish farming.

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
