Module 15: Ocean Resources Part 2

In class we were able to see a video of Mr. Wilson’s brother and just what it takes to fish for blue fin tuna off the coast of Maine.  Here we see Tyler Winkelmeyer demonstrating to the class how to identify and measure lobsters.  Good job Tyler!

Sea creatures are designed to reproduce in order to overcome the population’s loss to predators and natural death.  Fishing by people is considered predatory practice, therefore we studied our responsibility to sea populations in terms of renewable and nonrenewable resources. To prevent  a decline in numbers (assuming there are no changes in other factors), the number of fish caught in a population can be more than the number of new individuals replenishing through reproduction is what Fisheries biologists call sustainable yield.

Many nations have agreed to establish exclusive economic zones where the resources found up to 200 nautical mines offshore belong exclusively to the geographically bordering country, and that country has complete control of all those resources located with that area.  Other nations may not fish in the zone unless they have signed agreements or have paid the country for permission to do so.  What and how much they catch is specifically stated in these agreements.  this helps protect the populations of species in a given area.

We hope to visit Mote Marine’s Aquaculture facility during one of our field trips in April.  Here we will see first hand mariculture being put into practice.  Aquaculture in one of Florida’s leading industries.

Other living resources we use from the ocean are corals, shells, oyster pearls that are made into jewerly, seaweed used in food and plastics, bacteria used in products that enhance immune health, heal skin disorders and other pharmaceuticals.  Other animal products are also taken from the sea such as crocodiles, seals, sea turtles, sponges and pufferfish.

Non-living ocean resources include oil and gas, Manganese deposits as well as nickel, cooper, cobalt, iron and zinc.  Sea water itself is used in desalination processes that removes the salts to make drinking water and salt products.  Lastly, waves, currents and tides are used as renewable energy sources.
