2.2.1.1 Temperature, salinity and dissolved oxygen After extensive studies, several authors have mentioned certain physical, chemical and biological parameters of water and sediment as important for the aquaculture of marine shrimps. Along with dissolved oxygen, water temperature and salinity are considered as significant parameters because of their close association in aquatic ecosystem (OSPAR, 2005). The maximum water temperature recommended by Nunes et al., 2005 and ABBC, 2005 was 32°C,…

had been a leader for a while. I thought back to the end of my tenth grade year when a group of my friends and I all went to Oregon to tech Outdoor School as an end-of-the-year project. We were teaching fifth and sixth graders about the forest, the estuary, and the ocean. Even though we had just learned about each of these environments the day before. We all lead a group of about seven to nine boys and girls around and taught them about three different environments that are in that area. In…

the house all day. In the comment, “After three days he’d had enough. He had to do something, get outside, take a walk,” (Author, #), we see that the author is leading us up to the conflict. The climax of the story is when Wallace goes down to the estuary and it caught smoking weed and snaps at the man in the green jacket. The climax gives us a conflict between the man in the green jacket and Wallace. The author made the comment, “Wallace decided he was going to let the man say whatever he…

When looking at all of the environmental disasters of the United States, the BP Oil Spill and Dust Bowl are by far two of the most devastating disasters to the surrounding environment and ecosystem. Although both natural disasters have different characteristics and environmental effects, each disaster greatly impacted the surrounding ecosystems from before and after the disasters. Although the Gulf of Mexico before the BP oil spill was still known for its suffering under the effects of coastal…

The culture and economy of shellfishing Shellfishing and aquaculture have been an important part of the culture and economy of Cape Cod for many years. Shellfishing is a major contributor to Massachusetts economy, and Cape Cod’s coastal economy also relies on recreational and commercial shellfishing, as well as the tourist and seafood industries (Ensuring a Shellfish Future, Maggio, 2015). On Cape Cod, the commercial shellfish aquaculture supports 1,400 jobs, 17,000 recreational harvesters…

Rhizophora mangle the red plague Mangroves are a predominant form of vegetation that can be found in intertidal zones of tropical estuaries, lagoons, sheltered shorelines and in subtropical coastlines (Allen, 1998). Mangroves are trees and shrubs that have adapted to living in saltwater environments. They are propped up, out of the water, by dense, tangled roots that allow them to obtain oxygen in oxygen poor sediments. Their roots also allow the tree to remain supported during the rise and…

Introduction For over 100 million years sea turtles have covered extensive distances across the world 's oceans, filling a fundamental role in the composure of marine habitats. Seven different species of these aquatic reptiles graze our ocean waters, from the shallow seagrass beds of the Indian Ocean, to the vibrant reefs of the Coral Triangle, and even the sandy beaches of the Eastern Pacific. Human activities have tipped the scales in opposition to the survival of these ancient mariners, which…

MPAs are not only active in coastal regions, but are utilized to protect estuaries, open ocean, Great Lakes, and inter-tidal zones (Wenzel and D’Iorio 2011). They have been implemented in countries including but not limited to the United States, New Zealand, the Philippines, Canada, and Australia. To better understand the complex…

Ocean acidification is sometimes called “climate change’s evil twin,” and for a good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from…

Coastal geomorphology is similar to geomorphology, but the area of focus is on seas and oceans (Davidson-Arnott, 2010). Researches study the development and progression of the coast and how it reacts under particular conditions including sea level changes. The IPCC (Intergovernmental Panel on Climate Change) report in 2013 stated that sea level rise will occur in approximately 95% of the ocean area, with estimates that seas will rise between 26 and 82 cm. Therefore, we can assume it is probable…
