Introduction “Seafood includes edible aquatic life. Seafood includes creatures live in seawater, such as fish and shellfish i.e. crustaceans and edible seaweeds that is used for different purposes”. Seafood is not only consumed by humans but also by others creatures living in water and on land such as bigger fishes, bears, and whales. Seafood contains full of many of the things our bodies need to operate as nature planned. Seafood contains protein, vitamins, minerals, fats, omega-3 fatty acid. Although

In The Oyster Question, Christine Keiner utilizes environmental, agricultural, political, and social history perspectives to investigate the Maryland oyster industry and its decline throughout history to answer the question if the oyster industry should be privatized. She offers opposing viewpoints from scientists, politicians and local community members. She has managed to connect scientific history with environmental history with local history to bring together a comprehensive overview of the problems

The Chesapeake Bay and the Eastern Oyster The word Chesapeake, although there is some scholarly dispute, likely means “Great Bay of Shells” or “Great Shellfish Bay” in the language of the Algonquian Native Americans (“Oyster History”). This translation is appropriate and accurate to anyone familiar with the Chesapeake Bay and its rich history of oysters. The Chesapeake Bay is the largest estuary in the United States with over 150 rivers and streams flow into its basin. It measures roughly 200 miles

the oldest of all sea turtles, more than 150 million years. The Leatherback is unique compared to other sea turtles, “scientists once placed it in a group separate from the other turtles” (Orenstein 112). They consume jellyfish and tunicates (filter feeders). They do not posses a shell like other sea turtles, instead, its leathery skin covers a flexible matrix bone which enables it to dive greater depths. Leatherback has been recorded diving in temperatures as low as 0.4 degrees Celsius (32.8 degrees

Cetaceans in Scottish waters Abstract Scottish coastal waters accommodate several populations of cetacean species. However, the interference of human activities on the marine habitat has been increasing gradually and thus, impacted the marine creatures negatively. This paper introduces different cetaceans that can be found in seas surrounding Scotland, threats that can affect them and how humans can tackle the problems through conservation and management. Some suggestions may not be successfully

My Favorite Fishing Day It was about six o'clock in the morning when my grandfather comes in to wake me up and said time to get ready and come get some breakfast. I had coffee and toast like I do every morning I spend with him. My dad was already up and packed our lunch and a cooler full of drinks. At 6:40 we went to the bait shop where our charter captain's boat is at. It was a warm morning off the start and the sound was a little rough but I knew we were still going and were going to make it a

Tying this back to climate change, it the levels of these salt marshes are affected by the rise in seawater. However, if the cordgrass and marsh hay experience more or less stress from higher or lower tides than they are used to, the soils within each area will be disturbed. The higher the sea level rises, the more tides increase in number as well as speed. If the tides speed up and become more frequent, it is possible that this could dislodge newly planted seeds and disturb the populations increasing

intricate ecological community inhabits the ‘rocky intertidal’ areas. The variety of rocks is home to an array of slimy, squishy, and colorful organisms. This intertidal community is comprised of nine species: three different algae, three stationary filter-feeders, and three mobile consumers. The three algae, Nori Seaweed, Black Pine, and Coral Weed, are the community’s producers and inhabit the bottom of the food chain. The next three species are stationary consumers. They are Mussel, Goose Neck Barnacle

ecological niches they experience large fluctuations in their physicochemical environments, predominantly temperature, nutrition, salinity and oxygen tension (Irwin, S., Wall, V. & Davenport, J. 2007). Artemia Franciscana is considered a phagotrophic filter feeder (Evjemo, J.O. & Olsen, Y. 1999) which uses its larval antennae to start ingesting food (Evjemo, J.O. & Olsen, Y. 1999). The optimal temperature for growth in Artemia Franciscana ranges between 25 and 30oC (Evjemo, J.O. & Olsen, Y. 1999). Among

Bioerosion and Reef Ecology The breakdown of calcareous substrates among coral reefs, or bioerosion, is a facet of reef ecology too often forgotten. The process plays a much more important role than it is usually credited with. Bioeroding species, consisting of many different types of organisms that act on the environment in a seemingly endless variety of ways, interact with the ecosystem and with each other as part of the reef growth and degradation cycle. The degradation portion of this cycle
