Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

THE DIGESTIVE TRACT OF CARASSIUS AURATUS

The Biological Bulletin, 1940
1. The digestive tube of Carassius auratus closely resembles that of Campostoma anonsalum (Rafinesque).2. Study of the gross structure brought out the following characteristics: the posterior pharynx possesses pharyngeal teeth which bite on a dorsal horny pad; a dorsal diverticulum leading to the pneumatic duct extends from the short oesophagus; the ...

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Dietary Tea Polyphenols Improve Growth Performance, Physiological Health and Economic Efficiency in Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Tea polyphenols (TPs) are natural bioactive compounds extensively used in aquaculture diets as a functional supplement because of their antioxidant, antimicrobial and immunomodulatory potential. Four isonitrogenous diets (crude protein: 30%) were designed with incorporating TPs at levels of 0% (control, TPs‐0), 0.025% (TPs‐1), 0.05% (TPs‐2 ...

Response of the Diet Composition of Carassius auratus to Water Quality in Dianchi Lake, China

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Understanding the relationship between the diet composition of fish and water quality is significant for assessing fish responses to habitat changes. However, due to the complexity and diversity of both fish feeding and water quality, the relationship between the diet composition of fish and water quality is not fully understood to date.

Effect of mixture metals on the fish (Carassius auratus) ATPase activity and its genotoxicity

浙江大学学报. 农业与生命科学版, 2001
The Carassius auratus genetoxicity and ATPase activity for mixture metals have been studied. The results demonstrated that there was negative linear correlation between the Na/K ATPase activity and the exposure concentration of mixture metals in the ...
