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.
Fluctuating conditions of their habitat has led to a massive population decline. “Saving the smelt” has ignited tremendous controversy over the measures considered for saving their species. When considering the deep ecologist perspective, there is an obvious need to assure the safety of the delta smelt, despite the negative effect upon the economic standing of those dependent on water from the large pumps of the estuary. Efforts to protect the endangered fish from further decline have focused on limiting or modifying the large-scale pumping activities of state and federal water projects at the southern end of the estuary. Recognized by many as the “smeltdown in the Delta,” the extinction trajectory of delta smelt, has left the once-abundant species in critical condition due to record-high water diversions, pollutants, and harmful nonnative species that thrive in the damaged delta habitat.
While Columbus and his crew journeyed across the Atlantic Ocean, they would encounter their second peril. The importance of proper storage for food and water became an issue. Even though Columbus stocked their three ships with sardines, anchovies, beans, chickpeas, lintels, water, vinegar, wine, and other key foods for survival, the transportation in wooden casks with brine, wasn’t a well thought out plan. Columbus and his crew would later learn that the wooden casks with brine would leak and dry foods would get wet. This wouldn’t have happened if they would have had the proper knowledge to secure the brine with more efficient containers and or had refrigeration for them to transport their food and drinks like we do today.
It describes how the Bluefin is viewed in many different lights either as food or an economic goldmine to those that fish them, legally or illegally and how powerless the authorities are to stopping the underground trade. They then present the idea that there is only way to preserving the species; by commercial fish farming in protected waters. Overfishing and Fisheries Management: Stocks of commercially fished species must be managed carefully to ensure that the catch (take) does not undermine the sustainability of the fishery. In Australia, about 50 species make up 85% of the commercial catch. The most important species are either fully exploited and are being managed to achieve a sustainable yield, or have been overexploited and are now being managed to allow recovery.
The number of swimming brine shrimp for Trial 4 was slightly less than that of Trial 1. This could be due to oxygen levels in the lab, or it could be due to human error in counting the numbers of eggs from the procedure, or counting the numbers of swimming brine shrimp and dead brine shrimp in analysis. Additionally, actual amounts of ethanol concentrations could have slightly varied due to human error in measuring the ethanol consistently among groups causing slightly variable viability rates. Water may also have splashed out of the dishes, contributing to a flaw in measurement. In the future, the entire study should be performed by individual groups in order to aid elimination of error.
If sharks were to be extinct then we would not be able to go with our families to the beach to have a fun in the waters as the water would be disgusting and not swimmable. While the numbers of large sharks have been going low it has led to the collapse of fisheries being able to go out to sea to fish as sharks play an important role of keeping the fish and coral reefs healthy. As large sharks do have an important role in the ocean, we do have to be cautious about where we swim as we could be in there territory or near predators. If you do take a shark out of there eco-system then in conclusion there will be bad consequences, because they keep their eco-system healthy and clean. For example imagine you at home doing your own thing then out of nowhere an intruder comes in and kidnaps you and while that happens there will be consequences but in the end you will end up being shot, not a good thing to think about so we should think the same about sharks.
Yorktown Technologies’ GloFish venture was no different. Although, Yorktown Technologies’ business plan centered on the marketing of a biotech technology involving fish, it nonetheless provoked censure from some scientific and animal rights communities. The company also encountered difficulties from several regulating factions of a number of Fish and Game Commissions. With disappointing revenues in 2004, Yorktown Technologies’ marketing position was tenuous and in need of revamping. Case Analysis In the United States, the sale of freshwater ornamental fish and related products is an industry worth over 700 million dollars annually (Kerin
These fish pose a significant threat to the great lakes due to their large size and feeding habits. The bighead carp consume vast amounts of food and quickly dominate a water body. The Asian Carp were imported around the nineteen seventies and were used for aquaculture operations. Although some believe that the Asian Carp should be kept alive because they are rich in omega-3s and are now being served in restaurants, Asian carp should be removed or eliminated completely from the great lakes because they will decimate the billion dollar fishing industry in the Great Lakes, and permanently damage the ecosystem. Some believe that the Asian Carp should be kept alive because of their nutritional value and their recent emergence in restaurants.
As youth we need to help as best we can in creating our ocean more sustainable. Many people are unaware of what is happening on our oil rigs, we need to make sure everyone is educated on what is going on and make sure that everyone is trying to make the ocean more sustainable. Oil spills are very dangerous to marine life; we need to make sure we do everything to protect it. Many people rely on Newfoundland waters for fish to eat, and to make a living. Contaminating these waters will not only harm the wildlife, but it will kill a source of food that is so dominant in Newfoundland, and also will harm hundreds of people’s jobs.
Furthermore, it would also have a heavy influence on the amount and quality of farming. If the water were to become polluted due to human contamination, then that would result in even less fresh water for farming food. This would be extremely detrimental due to the fact that the population of California is expected to grow from 35 million to 55 million by 2050. Therefore, resources would become even scarcer, and prices, in turn, will sky rocket. Each of these components are a recipe for failure, and would leave the southern part of the state-which contains two-thirds of the state’s population-with very little fresh water
