Farm raised fish versus wild caught Cul 110 exam #3 Alexis Halstead There have been many different long standing arguments about the differences between farms raised fish and wild caught fish. There are good arguments against which is better than the other. Although these farming practices have their difference, eating fish has great health benefits and that should also be taken into consideration when deciding which product you will be purchasing. Fish are widely advertised for there health benefits, but there are many different controversies surrounding how they caught and able to be produced in mass quantities. Eating about two servings of fish per week provides healthy amounts omega-3 fatty acids that can help to lower cardiovascular disease.
Shrimpers have made some steps toward recovery even after a difficult opening commercial season last August. The domestic shrimp market remains uncertain but at least at the State and Federal level are conscious about helping out. Eight out of twelve from the 2011 Gulf Coast Shrimp Survey Phase 1 that I conducted mistrusts the U.S. and the State government in the aftermath of the BP oil spill. Five out of these eight people said that they do not care where their shrimp may come from. Congressman Ron Paul stated that “the United States domestic shrimping industry is a vital social and economic force in many coastal communities across the United States…A thriving shrimping industry benefits not only those who own and operate shrimp boats, but also food processors, hotels and restaurants, grocery stores, and all those who work in and service these industries” (Paul 2002: 1).
The by-catch and pollution must also be monitored. There have been positive results from this new management overall, though many salmon populations as well as other marine populations continue to be in decline. It is important that we as consumers choose fish products from sustainable fisheries and understand what this means for marine environments. If salmon continue to be fished and farmed in ways that are damaging to the environment, collapse of the entire industry may occur. This can cause unforeseen economic and ecologic problems that may be irreversible.
The native plants Kelp is important because it provides shelter and food for a lot of sea creatures. Kelp is also used by humans for many products, including toothpaste and ice cream. Kelp also serves as a buffer by absorbing energy from waves before the waves hit the shoreline, protecting many of the sandy beaches along the California coast. Phytoplankton is tiny plant that serves as food for many of the ocean creatures from the smallest of fish to large whales. Some scientists estimate that phytoplankton provide the earth with almost half of its oxygen.
Additionally, there are indirect (unintentional) human actions such as economic pressures and aquaculture. I would also argue that the current state of the global economy is encouraging perpetuation of “aquaculture” due to generally lower prices for farm-raised salmon compared to wild-caught salmon. This being said, some may argue that efforts to increase wild salmon populations through human intervention (i.e. barging and hatcheries), or using aquaculture as a means to “grow” and harvest captive salmon in order to reduce fishing of wild salmon, is beneficial to populations. However, these arguments do not have scientific support.
As the ppm of dissolved oxygen increased so did the amount of fish there were in the water. Clearly, the fish prefer to be in water that has more ppm of dissolved oxygen. 2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = Based on research done by Elshout, Pires, Leuven, Bonga, and Hendriks, lower Dissolved Oxygen levels have a major impact on the fish population and reproduction.
Quotas should be set on catches, based on scientific estimates for the size of the fish stock (Collins, 1997). Making the public more aware could be another way to help protect these species. Many people probably don’t even know what a menhaden is, or how important they are in the human food chain. These fish are prey for many bigger game fish, such as bass and bluefish. People tend to preserve things they have a better understanding
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
Scientific Name: Pomatomus saltatrix Common Name: Blue Fish Culture method: Hook and line, pound nets, seines, and trawls. Where/How harvested: The majority of bluefish are caught by recreational fishermen. Most commercial fisheries for bluefish use gillnet, but other types of nets are used to a lesser degree (generally small mesh nets). Sustainability: “Sustainability is about balancing the economic and nutritional needs of today with preservation of ocean resources for tomorrow.” Sustainability has emerged as a result of significant concerns about the unintended social, environmental, and economic consequences of rapid population growth, economic growth and consumption of our natural resources.

The IRL is both a unique, and diverse, shallow-water estuary of national significance and makes up approximately 40% of Florida’s east coast. Even though the IRL is of environmental importance, the lagoon is also an economic engine. The IRL generates more than $3.7 billion per year to the state of Florida. The urbanization, disproportionate freshwater releases, contamination, poor water quality, loss of habitat, such as sea grasses and mangroves, turn down of fisheries, and diseases in marine mammals have affected the health of the IRL, according to Indianriverlagoon.org in
