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: 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 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: Northern pike is an important freshwater species for restocking and recreational fishing. This study aims to improve the fertilization rates of northern pike by using different activation media. The results show that selected activation media can significantly increase the reproductive efficiency of this species.

Summary: The concentrations of mercury in fish are influenced by complex biogeochemical and ecological interactions. These interactions have profound effects on fish mercury concentrations, particularly in northern latitudes. The study found that fish growth rates and concentrations of methylmercury in benthic invertebrates are important factors affecting mercury concentrations in Northern Pike. These variables are influenced by concentrations of dissolved organic carbon, methylmercury, and total mercury in lakes, which are ultimately driven by catchment characteristics.

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: 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 used recreational angling data to assess the population development of northern pike along the Swedish Baltic Sea coast. The findings showed a significant decrease in the abundance of large pike since 1990, potentially due to increased mortality from recreational fisheries and higher predation pressure from grey seals and great cormorants.

Summary: The effect of size grading on rearing effectiveness in pike larvae and juvenile was evaluated. The results showed that size grading reduced cannibalism among large fish but did not improve their survival and biomass gain.

Summary: The expansion of common reed and changes in submerged vegetation have been influenced by eutrophication and reduced grazing in the Baltic Sea. While reed is important as nursery habitat for fish, extensive emergent vegetation may reduce the abundance and biodiversity of predatory fish. The study shows that the presence of reed beds and rooted submerged vegetation are important factors for the abundance of adult pike during the spawning season.

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: 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 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: 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.
