Effects of High Carbohydrate Diet-Modulated Microbiota on Gut Health in Chinese Perch

open access: yesFrontiers in Microbiology, 2020
High carbohydrate diet-induced damage in gut is linked to changes in gut permeability and microbiota. However, the mechanisms of action are not clear, especially in non-mammals.

Histone Methylation of H3K4 Involved in the Anorexia of Carnivorous Mandarin Fish (Siniperca chuatsi) After Feeding on a Carbohydrate-Rich Diet

open access: yesFrontiers in Endocrinology, 2020
Food intake of carnivorous fish decreases after feeding on a carbohydrate-rich diet. However, the molecular mechanism underlying the anorexia caused by high-carbohydrate diets has remained elusive.

Optimal Open-Loop Control of Discrete Deterministic Systems by Application of the Perch School Metaheuristic Optimization Algorithm

open access: yesAlgorithms, 2022
A new hybrid metaheuristic method for optimizing the objective function on a parallelepiped set of admissible solutions is proposed. It mimics the behavior of a school of river perch when looking for food. The algorithm uses the ideas of several methods:

Lipid deposition pattern and adaptive strategy in response to dietary fat in Chinese perch (Siniperca chuatsi)

open access: yesNutrition & Metabolism, 2018
Background Previous studies in teleost have demonstrated the adaptive strategy to maintain hepatic lipid homeostasis within certain limit. The excess of fat-intake could induce abnormal lipid deposition in liver but not adipose tissue.

Indirect effect of different dietary protein to energy ratio of bait fish mori diets on growth performance, body composition, nitrogen metabolism and relative AMPK & mTOR pathway gene expression of Chinese perch

open access: yesAquaculture Reports, 2020
Chinese perch (Siniperca chuatsi) is an important economic freshwater carnivorous fish. Commonly feeds on other live fish or bait fish, and accept an artificial diet only after standard training. The feeding habit of Chinese perch caused high aquaculture

Optimalisation of the Activation Medium and Effect of Inhibiting Activities of Acid Phosphatase, Lactate Dehydrogenase and β-N-Acetylglucosaminidase on the Fertilisation Success of Eurasian Perch (Perca fluviatilis L.)

open access: yesAnimals, 2022
Although methods for the artificial reproduction of perch have been developed, a lack of information remains regarding the enzymes present in its semen, as well as their role in the fertilisation process.

Histological alterations under metal exposure in gills of European perch (Perca fluviatilis L.) from Topolnitsa Reservoir (Bulgaria) [PDF]

open access: yesArchives of Biological Sciences, 2015
Topolnitsa Reservoir is located in a region of Bulgaria rich in copper mines where intensive mining has been ongoing for several decades. General data on the ecological status of the reservoir and the effects of metal on fish is relatively ...

Competition between Invasive Ruffe (Gymnocephalus cernua) and Native Yellow Perch (Perca flavescens) in Experimental Mesocosms

open access: yesFishes, 2020
Ruffe (Gymnocephalus cernua) were introduced to North America from Europe in the mid-1980s and based on similar diets and habit use may compete with yellow perch (Perca flavescens).

DNA Methylation of T1R1 Gene in the Vegetarian Adaptation of Grass Carp Ctenopharyngodon idella

open access: yesScientific Reports, 2018
Although previous studies have indicated importance of taste receptors in food habits formation in mammals, little is known about those in fish. Grass carp is an excellent model for studying vegetarian adaptation, as it shows food habit transition from ...

Relationship between biological characteristics of fish and their contamination with trace metals: a case study of perch Perca fluviatilis L. in the Baltic Sea; pp. 193–201 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2013
Biological characteristics of fish are expected to affect the bioaccumulation patterns of trace metals in aquatic organisms. Nonetheless, this topic is relatively unstudied among fish species.
