Effects of autochthonous strains mixture on gut microbiota and metabolic profile in cobia (Rachycentron canadum)

Scientific Reports, 2022
The fish immune system is a topic or subject that offers a unique understanding of defensive system evolution in vertebrate heredity. While gut microbiota plays several roles in fish: well-being, promoting health and growth, resistance to bacterial ...

Association of Mitochondrial DNA Levels in Peripheral Blood Leukocytes With Physical Performance in Older Adults

Geriatrics &Gerontology International, Volume 26, Issue 4, April 2026.
Reduced mitochondrial DNA copy number in leukocytes is associated with reduced gait ability in women and with higher handgrip strength in men. Reduced mitochondrial DNA copy number in leukocytes is also associated with lower serum iron in women, lower HDL‐C in men, and higher uric acid and CRP in men.

First Detection of Lactococcus formosensis subsp. formosensis in Rainbow Trout (Oncorhynchus mykiss) in Europe

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis are etiological agents of piscine lactococcosis, a disease reported in Italy since the early 1990s and linked to significant aquaculture losses. To the best of our knowledge, this study reports the first detection of L. formosensis subsp. formosensis in farmed rainbow trout (

First Report of Nephrocalcinosis in Aquacultured Brazilian Sardine (Sardinella brasiliensis Steindachner, 1879)

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT While nephrocalcinosis (kidney stones) is uncommon in wild teleost fish, various environmental and nutritional factors could lead to its occurrence in aquacultured fish. This study presents the first documented case of kidney stones in aquacultured Brazilian sardine (Sardinella brasiliensis). During necropsy, eighteen hard, white kidney stones

Behavioral Evidence of Predator–Predator Commensalism: Cobia Track and Feed on Prey Disturbed by Southern Stingrays

Ethology, Volume 132, Issue 3, Page 225-234, March 2026.
We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, Florida. Using drone‐based observations, we recorded a 7‐min sequence in which a cobia closely tracked the stingray's movements and fed on prey disturbed ...

Artificial light including blue-green wavelengths promotes growth of Rachycentron canadum with mRNA upregulation of appetite, growth and lipid synthesis

Frontiers in Marine Science
IntroductionCues from light, including photoperiod, intensity, and wavelength, can all impact physiology in fish. This study investigated the effect of light wavelengths on growth performance in the cobia Rachycentron canadum, a commercially valuable ...

Thyroid gland development in Rachycentron canadum during early life stages

Anais da Academia Brasileira de Ciências, 2014
The aim of this study was to describe the ontogeny of thyroid follicles in cobia Rachycentron canadum. Larvae were sampled daily (n=15 - 20) from hatching until 15 dah (days after hatching).

Is Maize Gluten a Sustainable and Effective Aquafeed Protein?

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Maize gluten meal (MGM) can be considered unbalanced in its amino acid profile when used as a fishmeal replacement in aquafeeds. To address this, the present study evaluated MGM as the primary dietary protein source at two inclusion levels in common carp (Cyprinus carpio), with supplementation of crystalline essential amino acids (EAA).
