Document Summary
Final paper outline 10% (monday, february 13, 2017) Final paper 40% (thursday, march 30, 2017) Earth is made up of ~70% water: fish found in virtually all types of environments with a source of water. Evidence of fish hooks ~50,000 years ago; made from bones. Most human history = small impact on fish populations: ~1800, over fishing started to rise and be a discussion to the public. Fisheries science: fisheries biology: biology of fish and fish populations, basic fish biology to develop optimal strategies to manage and conserve fish populations, based on biological principles. Human impacts: many issues and impacts on fish and fish populations. Wild fisheries can be a renewable resource through proper management. Aquaculture: growing of fish: effects of grown vs natural fish populations, example: salmon (natural) population on the decline. Salmon (grown) population on the incline: decimation of natural populations, non-native species = outbreaks, changes genetic makeup/ diversity of natural species.
