Trichlorfon is among the most commonly used products to treat fish parasites in aquaculture. We investigated the effectiveness of propolis in alleviating the toxicity of trichlorfon on haematological and oxidant/antioxidant parameters in carp Cyprinus carpio. Fish were exposed to sublethal concentrations (11 and 22 mg l-1) of trichlorfon, and propolis (10 mg kg-1 of fish weight) was simultaneously administered. At the end of 14 d administration, blood and tissue (liver, kidney, gill) samples were collected. Haematological changes (red and white blood cell count, haemoglobin concentration, haematocrit level and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration) were determined in the blood samples, while antioxidant parameters (malondialdehyde and reduced glutathione levels and superoxide dismutase, catalase and glutathione peroxidase activities) were evaluated in the liver, kidney and gill samples. Trichlorfon led to negative alterations in the haematological and antioxidant parameters investigated. The administration of propolis alleviated this effect and suggests that fish treated with trichlorfon improve their physiological status when fed a propolis-supplemented diet.

Three fish species (common carp, Wels catfish, and silver carp) were collected from three locations along the Danube River in Serbia, and fish meat was analyzed for the content of toxic elements, micro- and macrominerals. Silver carp had the highest lead (Pb), arsenic (As), and cadmium (Cd) content, while Wels catfish had the highest level of mercury (Hg). Moreover, metal pollution index (MPI) ranged from 0.

The demand for extended shelf life and food safety in the food industry continues to rise. At the same time, the environmental burden of traditional plastic packaging materials is becoming increasingly serious. Therefore, in this study, an intelligent bilayer film with a pH-sensitive inner indicator film based on Artemisia Sphaerocephala Krasch.

Black carp (Mylopharyngodon piceus) is one of the "four famous domestic fishes" in China and an important economic fish in freshwater aquaculture. A high-quality genome is essential for advancing future biological research and breeding programs for this species. In this study, we aimed to generate a high-quality chromosome-level genome assembly of black carp using Nanopore and Hi-C technologies.

Goldfish (), subjected to millennia of artificial selection and breeding, have diversified into numerous ornamental varieties, such as the celestial-eye (CE) goldfish, noted for its unique dorsal eye rotation. Previous studies have primarily focused on anatomical modifications in CE goldfish eyes, yet the molecular underpinnings of their distinctive eye orientation remain poorly understood. This study employed high-throughput transcriptome and proteome sequencing on 110-day-old full-sibling CE goldfish, which displayed either anterior or upward eye rotations.
