The present study was undertaken to investigate the acute toxicity of two heavy metals cadmium and mercury in the juveniles of Asian seabass Lates calcarifer (Bloch) which is considered as an important candidate fish species for brackishwater and freshwater aquaculture. Experiments for the bioassay were performed in static bioassay test condition according to the standard guidelines. The experiment was carried out in the FRP tanks under laboratory condition. The behavioral changes in the fish were observed for all test concentrations of both cadmium and mercury. Median lethal concentrations (LC50) were calculated for 24h, 48h, 72h and 96h by probit analysis. The LC50 values for 96h and 95% confidence intervals for the juveniles of seabass L. calcarifer showed 6.08 ppm for cadmium and 1.03 ppm for mercury. Furthermore, the exposed specimens showed dose and duration dependent, abnormal behavior and hyperactivity. Mercury indicated more toxic than cadmium for seabass L. calcarifer.Keywords

Background/Objectives: With ever increasing number and variety of security threats looming large that continually cause hassles to companies and governments, it is vital to ensure that the software applications are free from such vulnerabilities. The objective is to remove such vulnerabilities in applications coded in C/C++ programming languages conforming to ISO/ IEC standards, through static analysis and make the applications secure. Methods: Collected insecure coding constructs in C/C++ programming languages from authentic sources and created a repository of the same. Built a static analysis tool named "Vulnerability Reporter" to flag insecure coding constructs in the applications. The insecure coding constructs are identified by referring to the repository of vulnerabilities in C/C++ languages, prewritten to the tool. Findings: The tool parses the code and identifies and provides a report containing the vulnerable code in the given application along with their locations. It also provides suggestions for improvement of each potential vulnerability identified by the tool. The tool is scalable. Implementation/Application: The tool developed will find immense use in the academia and industry and will thereby enhance the security of application.Keywords
