The edible and sensory quality of fermented fish products, particularly the formation of garlic clove-structured muscle flakes (GCMF), play critical roles in consumer acceptance and consumption. Herein, aiming to obtain the optimal technical process, this study systematically explored the generation and dynamic evolution of GCMF structure of fermented mandarin fish, especially the integrity and peeling properties of GCMF, which would profoundly determine the textural properties of fish flesh. Meanwhile, flavor profiles were also concentrated during the formation of GCMF. Specifically, our results showed that the optimal fermentation conditions were 3% salt concentration and 7 days of fermentation at 7 °C. Under these conditions, the physicochemical indicators (moisture, pH, TVB-N) of the fermented fish remained within reasonable ranges and the sensory score; peeling integrity of GCMF and the texture properties reached the highest values. In addition, with the increase in fermentation time, the content of undesirable flavor compounds, especially nonanal and 1-octen-3-ol, gradually decreased. Overall, these findings provide a theoretical framework for the evaluation of GCMF structure and for understanding flavor development in fermented mandarin fish, thereby laying a foundation for improved quality control of fermented fish products.

Comprehensive characterization of transcriptional regulation during HCG-induced follicle maturation in mandarin fish (Siniperca chuatsi): Insights from transcriptomics.

In the first part of the article (Fish farm. and Fisheries, No. 12, 2025), the authors provided a fishery and biological description of silver carp and grass carp spawners from the cages of the Luchogorskaya Fish Hatchery Station of the TINRO Research Institute in Primorsky Krai. In the second part of the article, the authors summarized and analyzed the results of the last 25 seasons of growing fingerlings of these species and provided a description of natural population from the cooling pond. The body weight and survival rate of herbivorous fish grown in fry ponds under conditions of polyculture with carp fish and Amur predators were studied. The average weight of silver carp fry varied from 9.7 to 15.3 g when fed, and from 16.4 to 19.3 g for grass carp. The minimum weight of 4.5–5.5 g was recorded when the fish were kept without feeding and the ponds were fertilized with active sludge. The maximum weight of fingerlings is 20–80 g, and low survival rates are observed when feeding fish in seasons with a 10–25-day difference in the timing of planting carp and herbivorous fish and when fry of Chinese perch and Amur catfish weighing 0.3–1.7 g are released into ponds. The average survival rate of silver carp fingerlings over the years of research was slightly higher than that of grass carp, amounting to 16.1% and 14.7%, respectively. The herbivorous fish population of the cooling pond was formed as a result of regular stocking for 30 years and consists of individuals weighing from 5 g to 25 kg. The sex cycles of spawners from cages and cooling pond are significantly different. Silver carp reduced the number of phytoplankton, and grass carp almost completely destroyed macrophytes in the cooling pond. The population of herbivorous fish of the Amur line, living in the cooling pond of the Primorskaya power plant, is a reserve for replenishing the number of herbivorous fishes in the nearby Bikin and Ussuri rivers. The work is relevant in connection with the need to preserve, reproduce and keep clean the Amur line of herbivorous fish in Russia

Comparative analysis of brain transcriptomics, intestinal metabolomics and intestinal microbial diversity between two body weight-differentiated groups of mandarin fish (Siniperca chuatsi) after artificial feed acclimation.

This study aimed to investigate the response mechanisms of liver and gill tissues in mandarin fish (Siniperca chuatsi) at the histological, apoptotic, and gene expression levels during the weaning process from live prey to artificial feed. By analyzing fish samples at different domestication stages (D0, D7, D14), the results revealed that: (1) Histologically, the gill filaments exhibited shortening and thickening post-domestication, while the liver showed increased vacuolation; (2) apoptosis detection (TUNEL assay) and analysis of apoptosis-related gene (Bax/Bcl-2) expression indicated that the gill tissue experienced a significant increase in apoptosis at the mid-domestication stage (D7), which returned to baseline levels later (D14), whereas hepatic apoptosis showed no significant changes throughout the process; (3) transcriptome sequencing identified 3405 and 881 differentially expressed genes (DEGs) in the liver and gill tissues, respectively, and the significantly enriched pathways were steroid biosynthesis in the liver and alanine, aspartate, and glutamate metabolism in the gills. The apoptosis pathway was also significantly enriched in both tissues. GO analysis further indicated that the DEGs were primarily associated with metabolic processes, oxidative stress, and cell apoptosis. In conclusion, artificial feed domestication induces adaptive changes in the tissue structure and molecular profiles of the gill and liver in mandarin fish. The gill response to dietary transition is more rapid and characterized by a reversible apoptotic process, providing a theoretical foundation for understanding the stress mechanisms associated with domestication and promoting healthy aquaculture practices for this species.
