Fish stock

fisheries for Atlantic cod (Gadus morhua) experienced a complete crash in the early 1990s. The collapse extended from southern Labrador to the continental shelf off eastern Nova Scotia (Fig. 1). Abundance of the cod stocks were so low that a moratorium was set on commercial fisheries for cod stocks in 1992. Additionally, the cod fishery was an inherent part of Newfoundlanders social and cultural identity (Higgins, 2009). The fishery represented many individuals livelihood. Thus, with the collapse of the

Overfishing Overfishing refers to the act of overexploiting fish such that they reduce to unacceptable limits. The problem occurs if humans harvest large fish quantities than they can be replaced via natural reproduction in a given water body. Although catching large amounts of fish appear profitable, it has dire social and economic consequences. Overfishing interrupts balance of the marine ecosystem. Similarly, majority of the coastal population depends on fishing as their source of livelihood

considering that these animals have short life cycles and fast growth rates (Chung, et al., 2013). Mantle Length – body weight relationship have several applications, namely on fish biology, physiology, ecology, and fisheries assessment. It is an important item in the stock assessment models allow the estimation of biomass and fish condition from the length observations (Binohlan et al .1998). In the present study, the values of constant “b” in the dorsal mantle length-weight relationship of

recognized as one of the most serious issues facing humanity all over the world. There are severe consequences as a result of overfishing. Damaging fish stocks and habitat degradation are leading to ecosystem collapses. In addition, the extinction or even the depletion in some species such as Cod fish would affect the food chain. There will be no fish after 40 years if overfishing is continues and no practical action is taken (Shao, 2009). Finally, a solution to solve this problem is urgent as overfishing

surface currents. Not only does the cool current produces nutrient-rich waters that rise to the surface and attract multiple fish populations, but it causes the concentrated area to become vulnerable to anthropogenic ocean acidification. In addition, high winds are caused by coastal upwelling zones that are disrupted by El Nino. These high winds cause slow productivity, stock

Overfishing began in the early 1800’s when it was discovered that whale blubber could be utilized for oil lamps. Overfishing is when fish are taken from the ocean at a rate that is too fast for them to adequately repopulate. In contrast to every damaging anthropogenic activity, overfishing has taken the biggest toll on the marine ecosystems and has led many fish species to reduce rapidly and others to become extinct. In order to stop this before it is too late, we must enforce sustainable methods

operating costs and approach integrated fisheries bodies with favorably low investment cost. It also needs associations with commercial scale operations to demonstrate economic viability. Pacific Islands have many factors that favor aquaculture and stock enhancement development in the coastal areas. These factors are; abundant diversity of coral reef species (high demand), the location is close to Asia seafood markets, habitats are pristine therefore there is availability of

Fish are organisms that the world greatly relies upon. Making up a large chunk of the food chain, fish are a primary source of food for many land and sea animals. According to the FAO (Food and Agriculture Association of the United Nations), fish are a basal source of protein to about one billion people, and are extremely vital to poor and developing countries, supplying these countries’ people with 27% of their protein intake. Although fish are obviously an important staple to the earth’s food

The downfall of fish in the Atlantic Ocean is a result of numerous factors such as certain fishing techniques, climate change, and pollution. One type of fishing technique that is causing serious damage to marine life is bottom-trawling. Bottom-trawling is a form of fishing that involves a large net, about 60 meters wide, and dragging it along the bottom of the sea with heavy weights from a trawler. Bottom-trawling causes irreversible damage to coral life and slow-growing fish species, for example

Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing
