Big question: Why should we humans be concerned of overfishing?

                     * Because people are losing jobs after the cod fishery collapsed 

                     * Fish are dying and becoming endangered! 

                     * Important resourceful fish breeds are dying

1. What are the "Big Five" fish the majority of us eat?

    * Cod, Haddock, Tuna, Salmon, and Prawns

2. What is the reason for not eating sharks or other DEEPwater fish?

    * they tend to be slow growing, long-lived species which means they at extremely vulnerable to over-exploitation.

 

3. What are some "fish to eat," "fish to eat occasionally," and "fish to avoid?"

    * some fish to eat are usually from sustainable stocks or farms, or resilient to fishing pressure. 

    * some fish to eat OCCASIONALLY are lower resilience, and at risk of being sustainable. Also,

      they are probably recovering from previous exploitation.

    * some fish to avoid are Unsustainable, overfished, and poorly managed fisheries have messed up

      their cycle.

Marine Anthropods

1. What are examples of Maine anthropod's?

2.What's the difference between an anthropod's skeleton and a human? 

    *The animal lacks an internal skeleton and when they go thru their growing period, their exoskeleton sheds. Humans do not acquire this trait as our skeletons grow with our body.

3.Compare/contrast how anthropods and humans move blood in their circulatory systems.

   *

4.how do the eyes of anthropods differ from your eyes?

5.How do humans use marine anthropods?

Marine Science Words of Wisdom

Blue crabs start off life as not so attractive microscopic plankton.  In its life, a Chesapeake Bay Blue crab will molt 20-25 times, increasing its size by as much as 1/4 to 1/3 with each molt until it becomes the beautiful adult blue crabs we know and love.

Life lesson from a Blue Crab:  It may take a long time and a lot of changes to become the beautiful thing you were meant to be…stick with it…God has an amazing plan He is working to His perfection!

Nine Major Animal Phyla

The nine major phyla are:


1. Phylum Porifera - The Sponges
2. Phylum Coelenterata – The Coelenterates: jellyfish, hydras, corals

3. Phylum Platyhelminthes – The Flatworms: planaria, tapeworms

4. Phylum Nematoda – The Roundworms

5. Phylum Annelida – The Segmented Worms: earthworm, leech, sandworm

6. Phylum Arthropoda – The Arthropods: insects, spiders, crustaceans

7. Phylum Mollusca – The Mollusks: clams, snails, oysters, octopus

8. Phylum Echinodermata – The Echinoderms: sea stars, sea urchins

9. Phylum Chordata – The Chordates: fish, reptiles, amphibians, birds, mammals

• The types of habitats they can be found in are salt water, fresh water, and terrestrial.

• Some species dont have digestive systems, but those who do either have a complete or incomplete one.
• I have seen birds in the shy flying by as an example of a species in a phyla
