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 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 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 found that young northern pike individuals were more sensitive to pollution, but older fish showed higher overall bioaccumulation of toxic elements. Since there was no significant correlation between metal accumulation and fish condition, the relationship between age and accumulation of toxic elements was also insignificant.

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: In this study, a new ferritin was successfully extracted, purified, and identified from the liver of Northern pike. The reversible self-assembly characteristics of ferritin were utilized to fabricate chlorogenic acid-loaded apoferritin complex and sodium alginate-apoferritin co-encapsulate system. The prepared composites had improved thermal and UV radiation stability, and the sodium alginate complex showed better sustained-release effect.

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: The Northern pike population on the Island of Saaremaa, Estonia, shows temporal stability in genetic structure between geographically close locations, with reduced diversity in the north-western populations. There is a clear differentiation between the north-western and Gulf of Riga spawning grounds. These findings suggest that limited dispersal and natal homing behavior in Baltic pike promote the existence of temporally stable genetic divergence at small geographical scales, which is important for local adaptations. Therefore, conservation and management efforts should focus on preserving existing genetic differences and avoiding actions that increase genetic homogenization.

Summary: A new virus affecting aquatic turtles in Florida has been discovered, causing neurological symptoms, oral and genital ulcers, and bacterial infections. The virus was isolated and its genome was sequenced, revealing similarities to arenaviruses. Phylogenetic analysis shows that its RNA polymerase gene is highly divergent from known negative-sense RNA viruses, while the glycoprotein precursor gene is closely related to hantaviruses in fish. This turtle virus may represent a new taxon of negative-sense RNA viruses, possibly at the family, order, or class level. This study is important for understanding the evolution and classification of aquatic turtle viruses.
