The app's catch feature also enables fishermen to report their catches, which helps to keep track of the types and number of fish caught. This feature also helps fishermen to comply with local fishing regulations and conservation efforts. Overall, Fish Go is a useful app that helps Indonesian fishermen navigate the sea and locate the fish they need to catch.
