âš“ What are the causes for marine fisheries depletion?

Overfishing is closely tied to bycatch—the capture of unwanted sea life while fishing for a different species. This, too, is a serious marine threat that causes the needless loss of billions of fish, along with hundreds of thousands of sea turtles and cetaceans.

Whether it’s for the food industry or the aquarium industry, overfishing is a serious threat to the fish in our sea. There are many species of fish which simply need to remain in the sea, they are not necessary for food security or their lives are not suitable for captivity, yet the Food and Agriculture Organization have estimated that over 50% of species of marine fish have been fully or over-exploited.

The key problems, i.e., the need to provide incentives to fishers to engage constructively in fisheries management and the need to have strong legal support for predefined harvest strategies, apply...

The problem of water pollution mainly affects marine water fish. A variety of insecticides, pesticides, industrial effluents and domestic sewage find their way into many rivers and pose a serious problem for fisheries. The magnitude of pollution varies with the size of the river, the flow of water etc. Let us take few examples.

However, problems can result from the nonlinear nature of most fisheries models, in which estimates of two different parameters may be correlated, for instance. This can cause convergence problems for MCMC methods. In such cases, careful re-parameterization of the model is necessary (e.g. Meyer and Millar, 1999).

2. Current Status of Marine Fisheries. In general, considered on a single-species basis, many marine fisheries are fully exploited or overexploited, while relatively few seem to have the potential for increased exploitation. 1 In general, this is true both for the United States and globally, especially in estuarine, nearshore, and continental ...

However, there are serious questions as to the indefinite sustainability of aquaculture, especially with the proliferation of disease, weaker stocks, eutrophication of coastal zones, disruption of biological environments, negative effects from escaped farmed organisms ("World Fisheries" 2006).

Bycatch in fishing operations is one of the most serious threats to the recovery and conservation of sea turtle populations. To reduce this threat, NOAA Fisheries has instituted fishery observer programs to document the bycatch of protected species, including sea turtles, and implement regulations to reduce sea turtle bycatch in the Pacific and Atlantic Oceans and the Gulf of Mexico.

Most of the stocks of the top ten species, which account in total for about 30 percent of the world marine capture fisheries production in terms of quantity (Figure 6 on page 12), are fully exploited or overexploited and, therefore, cannot be expected to produce major increases in catches.
