Summary: Infection with eye flukes can lead to increased diet selectivity in European perch, with intensively infected fish showing preference for specific prey, while less intensively infected fish behave as generalist feeders with no particular prey preference in their diet. This highlights the indirect effect of parasites on the host's interaction with lower trophic levels and emphasizes the underestimated role of parasites in food web studies.

Summary: The study found that European perch in estuarine environments exhibit a high growth rate primarily due to abundant food and low interspecific competition, rather than optimal salinities. Additionally, the migration of fish into the delta during winter is likely a strategy to avoid high salinities at low temperatures and for spawning purposes. These findings have implications for the management of estuaries and coastal areas, particularly as climate change is impacting these environments and call for further research on other anadromous sub-populations of stenohaline freshwater fish.

Summary: Life history theory suggests that organisms should time their reproduction to maximize fitness. This study found that differences in breeding time among individuals in a perch population were associated with changes in hatching success and reproductive allocation strategies, as well as variation in offspring performance linked to temperature. These time-dependent adaptive differences within the population could influence the population's ability to cope with environmental challenges, such as global warming and exploitation.

Summary: This study investigated the presence of microplastic particles in the digestive system of perch in four south-alpine lakes and found that 86% of the analyzed specimens contained MPs. Despite the high number of ingested MPs, fish health was not affected, but the fullness index showed a potential interference with feeding activity.

Summary: In this study, the biodistribution of radionuclides 238U, 234U, 226Ra, 210Po, and 137Cs in organs and tissues of perch from five lakes in Sweden was investigated. The results showed that the main radionuclides in perch were 238U and 226Ra. It is advised to consume skinned fillets of perch to avoid the intake of radionuclides.

Summary: Perch and roach in boreal lakes were studied to examine the effect of summer temperature on recruitment and growth. Perch had a positive correlation with summer air temperature, while roach did not show a significant temperature effect. Fishing and age structure also influenced the relationship between temperature and perch year-class strength. Higher air temperature had a positive impact on perch growth rates, but its effect on roach growth was uncertain. These findings suggest that climate warming may benefit perch recruitment and growth.

Summary: Ultrasound is a rapid, non-invasive, and accurate method for determining the gender of Eurasian perch, with high accuracy rates for both males and females. This method can be highly beneficial for optimal broodstock management and aquaculture research in perch farming.

Summary: This study analyzed the genetic structure of P. fluviatilis in China using microsatellite markers. A large number of microsatellite markers were developed based on genomic data, and the genetic diversity of wild populations was evaluated. The results showed high genetic diversity in populations from Wulungu Lake, Jili Lake, and the Wulungu River, and medium genetic diversity in the Kalaeerqisi River.

Summary: Colour polymorphisms are examples of intraspecific variation, and different coloured individuals may exhibit differences in behavior that are influenced by environmental factors. In a study on the red devil fish, it was found that environmental factors had color morph-specific effects on behavior, indicating that environmentally driven behavioral differences may be context dependent and play a role in maintaining color morph-specific behavioral strategies.

Summary: Recent studies have found that Wolbachia infection can influence the personality and non-reproductive behaviors of spiders. Infected individuals are bolder but less aggressive, and their ability to perceive pesticides is compromised.

Summary: Stable isotope analysis and Bayesian mixing models were used to study the effects of feed components on the development of European perch tissues. Moderate inclusion of yellow mealworm larvae meal was found to promote tissue growth, while higher levels may decrease its contribution, with soy-derived ingredients also playing a significant role in tissue development.

Summary: The study suggests that lifelong exposure to PFASs may affect the thyroid hormone status and immune defense of wild perch. Conversely, PCBs do not seem to have significant effects on perch in terms of thyroid hormone levels or gene expression related to the thyroid.

Summary: Climate change affects seasonal environments and aquatic ecosystems by causing earlier and warmer springs, leading to significant changes in the thermal conditions for spawning and the viability of fish eggs and embryos. The study found that maternal size influenced the hatching success of Baltic Sea perch offspring, with larger females producing offspring with better performance across temperature treatments. Maintaining the size distribution of fish populations is crucial for the long-term productivity and viability of fish populations and the overall conservation of ecosystems.

Summary: Environmental change can affect the nutritional quality of fish muscle for human consumption, as shown in a study on Eurasian perch. The study found that perch allochthony increased with decreasing lake pH and increasing forest coverage, and perch muscle THg and n6-FA content also increased with forest coverage. In contrast, perch muscle DHA content decreased and ALA content increased towards shallower and murkier lakes. The study suggests that the quality of perch muscle decreases with increasing forest coverage and decreasing pH, potentially due to increasing fish allochthony.

Summary: Recent studies have found that high activity and boldness are typical traits of successful invaders. The topmouth gudgeon, currently the most widespread freshwater fish invader, may owe its invasive success to its flexible life-history traits rather than behavioral traits related to food competition.
