The present study analyzed the growth pattern of the stingray Urotrygon chilensis caught as bycatch by the shrimp fishery in the southeastern Mexican Pacific. From January to December 2012, the thoracic vertebrae of 491 females and 205 males were col...

The oxygen consumption of adult fish (Q) is proportional to their body weight (W) raised to a power, estimated as the slope (dQ) of a linear regression of log(Q) vs. log(W). Similarly, the gill surface area of adult fish (GSA) is proportional to W ra...

The trophic spectrum provides a useful method to investigate the trophic structure of fish communities. However, ontogenetic shifts in diet can cause variations in the trophic level with body size, thereby influencing the trophic structure of fish co...

The Lima River in northern Portugal serves as a vital habitat for diadromous fish species, yet it remains one of the least studied aquatic systems in the region. This study investigates the ecology and biology of key diadromous fish populations, incl...

In animal models, ketamine, a non-competitive N-methyl-D-aspartate (NMDA) antagonist, induces schizophrenia-like symptoms, such as positive and negative symptoms, as well as cognitive deficits. In the present study, we evaluated the behavioral respon...

Evaluating the interaction between dissolved oxygen (DO) and feeding rates (FRs) in fish is crucial for the precise regulation of aquaculture water environments. This study established four treatment groups: the CK group (DO = 6 mg/L, FR = 2% of body...

In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling diff...

This study aimed to investigate the effects of organic selenium-enriched yeast on the growth performance, muscle selenium deposition, and antioxidant capacity of juvenile Cherax quadricarinatus. Five experimental diets supplemented with 0.00 (control...

Additives in fish feeds are used worldwide to provide better productivity and improve fish’s health in facing disease outbreaks. This study aimed to identify the protective effect of taurine on the immune-related parameters and antioxidant enzy...

The ornamental fish trade involves multiple phases, from acquisition—whether through wild capture or aquaculture—to the final destination, often including long transport routes. Throughout this trade, fish encounter several stressors like...
