Use of PIC16f877/874 in Pneumatically Powered Net Gun
Abstract: It is critical to have capture crews who understand wild animal behaviour. This allows for captures without excessive chase time as well as fast and efficient processing. Animals that have been subjected to long and stressful chases before capture or that have been subjected to harassment and lengthy restraint and processing experiences are more likely to suffer health complications. Biological data will often be unusable. Animals may disperse in search …
