To obtain resources for fish, common structures include fishing boats equipped with nets or lines for catching fish, fish farms where fish are raised in controlled environments, and fish processing plants where fish are cleaned, processed, and packaged for distribution. Additionally, fishing ports and fish markets are important structures where fishermen can sell their catch to consumers.
Gills are an organ that fish have, that enables them to obtain oxygen from the water that they are in; it is what fish use instead of lungs.
