Overfishing

Bluefin tuna have suffered major population declines due to overfishing. Recent scientific research discusses various ways to implement management techniques to target the rapid declining population levels of Bluefin Tuna. However, much of this research demonstrates a substantial level of uncertainty about the basic biology of Bluefin Tuna. In particular, a lack of knowledge about the migratory patterns of Bluefin Tuna hinders the success of many proposed management techniques. Thus, it is…

According to the article “Search for the Missing Sea Otters: An Ecological Detective Story” by Mary E. Allen and Mark L. Kuhlmann, the sea otter population has been decreasing at a rapid pace since the 1990’s in Aleutian, Alaska. This is demonstrated by article “What Could be the Cause of Decreasing Otter Numbers” which states that in 1997, the decline of the sea otter population had increased to about 90%. They hypothesize that the decrease in the sea otter population has been caused by their…

Both climate change and human-induced changes, such as overfishing, pollution, dam construction, environmental degradation and land reclamation, are factors leading to changes in fish resources. Overfishing leads to the depletion of high-trophic level species, and has an impact on other species by altering the food chain. It has also been found that climate change, with more alterations…

Great Lakes are home to many animals and essential resource to living creatures. Life would be very different without the Great Lakes. The Great Lakes are an important part of Canadians resource. They are currently being destroyed by pollution, overfishing, chemical waste and climate change. Economically, without the Great Lakes, Canada would be negatively affected. Many jobs come along side with the Great Lakes. Fishing companies rely heavily on the Great Lakes to maintain a stable business.…

Fishing pressure is the main anthropogenic process threatening shark populations on a global and local scale. According to the United Nations' Food and Agriculture Organization (FAO) landings in the last six decades have nearly tripled, resulting in a worldwide decline of shark populations. The International Union for the Conservation of Nature (IUCN) carried out extensive assessments worldwide on the conservation status of shark species, and recently considerable effort has been placed on local…

Based on statistics, overfishing, contamination, and climate change are primary threats facing the trade. Pollock, cod, flatfish,salmon, and menhaden are the prime examples of domestic kind. All fish share 2 properties one being their habitat, and second being they have backbones.Which is also known as vertebrates. Fish are cold blooded,water-dwelling, vertebrates. The combo of gills, fins, and factor of living in water differentiates them from other creatures. Researchers believe that there are…

Climate change may be partly to blame for the decreasing number of Atlantic salmon. Some direct biological impacts of the change in climate include physiological stress, increased depletion of energy reserves, increased susceptibility and exposure to disease and disruptions to breeding efforts there is evidence that the temperature of the sea's surface may affect the young salmons survival. It is also thought that climate change may affect salmon growth rates or make their food less available.…

famous all around the world, attracting many settlers to the area. The cod industry became the staple of the economy for the East Coast and had increased living standards, increased employment, and increased household incomes. Until the years of overfishing, wasteful practices and lack of resource management took its toll, collapsing the cod fishing industry and caused turmoil for Atlantic Canada and the state altogether. The cod economy generated a billion dollars a year for Canada and when the…

The cod, an otherwise tough midsized omnivore predator, will, when it first becomes “aware “of threats to its survival from overfishing, begin to make adjustments in a number of ways, as do all living creatures, the most apparent of which in the cod is to come to sexual maturity at an increasingly early age, when it is a much smaller animal. In its attempt to avoid pending extinction…

Now in the 21st century, fish is becoming the world’s largest wild food source. Fish are a very important and highly consumed resource for the majority of the world, but in the wild, it is in limited supply. With commercial fishing increasing higher and higher yields of fish, the supply of available fish is becoming increasingly low. Fishing grounds that once used to be thriving with stocks of fish are becoming an expended resource. “Fish consumption increased by 31% from 1990 to 1997 but the…
