Abstract The practise of restocking and stock improvement as a means managing fisheries aquaculture has been widely used. However, it is difficult to claim that fish stocking effective due number challenges. One those the lack suitable monitoring assessment methods, although all approaches have their strengths weaknesses. If full benefits long-term sustainability are be realised, necessary examine effectiveness enhancement. Therefore, effective, rapid, dependable techniques necessary. In this study, we used an eDNA-based method identify G. cambodgiensis at 14 sites throughout Thailand's enhancement programme. eDNA from species was identified in water samples using quantitative polymerase chain reaction (qPCR) tests with primers probe specific . A successful would show positive results collected studied sites. Only five returned readings, which could considered stocking. locations contained were either confirmed natural habitats or regularly stocked large hatchery fish. demonstrated reliable, fast accurate alternative for measuring improvement.

This paper presents an investigation into the stability and control aspects of delayed partial differential equation (PDE) systems utilizing Lyapunov method. PDEs serve as powerful mathematical tools for modeling diverse intricate such heat transfer processes, chemical reactors, flexible arms, population dynamics. However, presence delays within feedback loop can introduce significant challenges, even minor potentially trigger system instability. To address this issue, method, renowned its efficacy in analysis, is employed to assess exponential a specific cohort PDE systems. By adopting Dirichlet boundary conditions incorporating delay-dependent techniques Galerkin method Halanay inequality, inherent properties these are rigorously examined. Notably, utilization study allows simplified it worth mentioning that analysis outcomes under Neumann combined align with those discussed herein. Furthermore, research endeavor delves implications obtained results terms considerations convergence rates. The integration aids approximating behavior dominant modes system, thereby enabling more comprehensive understanding control. exploration rates provides valuable insights speed at which achieved practice, thus enhancing practical applicability findings. contribute significantly broader comprehension effective elucidation behaviors not only impact but also offers design implementation strategies various domains. Ultimately, strives enhance reliability complex represented by PDEs, facilitating their across numerous scientific engineering applications.

Abstract Monochamus alternatus is one of the most important borers conifers and main vector pinewood nematode, Bursaphelenchus xylophilus , causal agent pine wilt disease. It causes massive death trees seriously affects health forest ecosystems. Traditionally, adults or larvae are identified by morphological molecular methods. However, diagnosing M. at different instars collected from forests expensive time‐consuming. Non‐destructive diagnostic protocols are, therefore, being developed to detect biological traces (i.e. exuviae, excreta) determine distribution spread this pest. In study, based on alignment mitochondrial DNA cytochrome oxidase subunit I ( COI ) gene sequences other insect species, we designed primer pair Mal‐SF/Mal‐SR probe Mal‐P for . TaqMan probe‐based qPCR was identify occurrence in amplifying samples obtained its adult, larva, frass, excreta exuviae. The amplification results were very effective. lowest amount that could be detected with a Cq 31.93 mixed 0.64 pg, showing high sensitivity. This assay can easily non‐target wood‐borer species using frass providing new protocol monitoring forests.
