Fishing the Ocean, and Farming the Ocean
Coral harvesting methods cause damage to coral reef ecosystems faster than the ecosystems can recover.Blast fishing is used because it maximizes the harvesting of fish, but it is also destructive to surrounding coral. Cyanide harvesting has similar effects. It can often kill coral along with the fish that it is targeting. Coral harvesting targets coral. If large portions of coral are removed it is difficult for the ecosystem to recover, as the coral as essential for the ecosystem and grows slowly over a period of many years. -e2020
First Nations used a variety of harvesting methods including fishing with nets, spears, or traps, hunting with bows and arrows or traps, gathering berries and plants by hand, and cultivating crops such as corn, beans, and squash. They also practiced sustainable harvesting techniques to ensure the long-term health of the land and resources.
the methods that were used were butts and they would dip them in the water then they would just come but sometimes they got bit off by sharks.
The four general methods of pest control is given below: Physical control methods such as fly screens; physical means of proofing for birds, possums & rodents or physical means of pest detection, such as trapping, can sometimes be a more effective and appropriate means of pest control in gaining long term control over a particular pest infestation. Cultural control methods of pest control such as improving ventilation to deter attack by termites or improving hygiene and sanitation measures to reduce the risk of cockroach infestation should always be undertaken, where possible, to make conditions less favorable for nuisance pests. Biological control methods such as the introduction of parasites or predators to eradicate a particular pest have a growing importance in Integrated Pest Management. Chemical control of pests, while often necessary, should be undertaken judiciously using the appropriate pesticide and means of application to minimize any risk to human, animal or plant life.
