Summary: This study evaluated the impacts of chronic exposures to nanosilver on Northern Pike, and found that prolonged exposure to nanosilver can result in reduced growth rate and prey availability for Northern Pike, with potential long-term effects even after the cessation of nanosilver additions.

Summary: The study found that different coagulants had similar effects on pike embryogenesis, but the timing of coagulant application should be carefully considered to avoid disrupting fish reproduction.

Summary: This study traced the evolution of sex determination in an entire teleost order through following the fate of a master sex-determining gene in northern pike, revealing that the gene originated from a gene duplication event 65 to 90 million years ago and remained sex linked on undifferentiated sex chromosomes for at least 56 million years in multiple species. Various independent species- or population-specific sex determination transitions, including the recent loss of a Y chromosome, were identified. Occasional sex reversals and genetic bottlenecks were proposed as non-adaptive explanations for sex determination transitions.

Summary: Understanding the relative effects of isolation by distance, environment, and resistance on neutral and adaptive genetic diversity is crucial for biodiversity protection. Studies show that different modes of isolation interactively shape genetic variation patterns, with neutral variation influenced by all three modes and adaptive variation mainly influenced by environmental conditions.

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: This paper presents data compilations on commercial fisheries catches of pike on the Polish coast and coastal lagoons, and provides some basic biological data gathered in Puck Bay from 2010 to 2015. The decline in commercial pike catches in Polish coastal lagoons began in the 1950s, and in Puck Bay, the main reasons for the rapid decline after the mid-1970s were suggested to be the loss of spawning grounds in coastal wetlands and the depletion of underwater meadows. The success of pike stocking in Puck Bay depends on the use of summer fry and measures such as banning gillnet fishing and unblocking canals for spawners.

Summary: This study assessed the vulnerability of five Pacific salmon species to invasive northern pike invasion using a modeling approach and Bayesian network, revealing pink salmon as the most vulnerable, followed by chum and coho salmon, with all five species being highly vulnerable in certain shared habitat. This framework can assist in prioritizing habitats and early monitoring of invading northern pike.

Summary: This study provides regression equations for estimating the body length and weight of pike based on measurements of vertebrae. The analysis shows that only length measurements can be used for estimating body length. Additionally, a case study demonstrates the potential of the new osteometrical data.

Summary: This study aimed to screen a set of microsatellite markers and assess the genetic variation of six pike-perch populations in China. The results showed that the populations were genetically different, and the genetic diversity and structure analysis provided useful information for the conservation management and effective utilization of pike-perch.

Summary: The study analyzed the presence of PFAS in tissues of pike and roach from two lakes in the Masurian Lake District in Poland, finding four PFAS substances above quantification limits and higher concentrations in kidneys. The findings provide insights into PFAS distribution and accumulation in biota.

Summary: This study investigated the variability in growth rates of Northern Pike in different lakes in the Northwest Territories of Canada, finding that lakes with greater catchment influence showed significantly slower growth rates for the fish. The study linked Northern Pike growth rates to trophic ecology and physicochemical data of the lakes and catchments, providing insights into potential impacts of future changes on fish growth and productivity in subarctic regions.

Summary: In this study, the quality and microbial dynamic structure of samples stored at 4°C were evaluated. The shelf life of the samples was determined to be around 8 days. The microbiota of the samples was mainly composed of Pseudomonas, Acinetobacter, Planifilum, Vagococcus, Hafnia, Mycobacterium, Thauera, and Yersinia. The volatile components were 3-methyl-1-butanol, ethyl acetate, and acetone. Glucose, lactic acid, and total sugar were negatively correlated with certain microorganisms in the early stage, while TVB-N and TCA-soluble peptides were positively correlated with other microorganisms in the later stage.

Summary: The study revealed varying levels of inbreeding in different populations of northern pike in Xinjiang, with the Irtysh River population showing distinctiveness in genomic relatedness and gene flow. Migration analysis indicated population spread influenced by the Irtysh River, with a significant migration signal from Bosten Lake to Ulungu Lake.
