Fisheries Depletion<br />By Roff and Moreno<br />

2.
Origen of Fisheries Depletion<br />Massive increase in demand for fish<br />Major fishing areas around the world have gone so far as to becomeover-exploited, there are no longer enough fish to reproduce and rebuild the population<br />populations havegrown, food consumption has grown, and more advanced fishing technology/techniqueshave been developed<br />Not many laws have been passed on thisissue<br />

3.
Current Status<br />this issue is behind some of the other major issues of the worldincluding pollution & deforestation despite the danger it poses to one of the world’s mostimportant food source<br />1/5 people on this planet depend on fishas their main source of protein<br />50% ofthe marine fisheries in the world are fully exploited, 20% are over-exploited<br />The only moves to actually stabilize fish populations are seen in fish farmingin China, Canada, and the US<br />

4.
Solutions <br />create designated fishing areas along major fishing depots<br />restricted areaswill be left alone so that populations can re-grow over a period of 3-5 years <br />rely on fish farms where humans breed and control the populations of fishin man-made bodies of water<br />The issue with this is that if any ofthese fish escape into wild waters then they can pose a threat to the ecology of that body ofwater<br />

5.
The Future of Fisheries Depletion<br />If everything continues as it has the allfisheries will continue or become over-exploited and eventually the world’s marine life canno longer survive<br />if the initiatives that are beginning around the world continue fishpopulations will gradually become more stable and continue to grow<br />the world will run out of seafood by 2048(Predicted by profesionals)<br />

6.
Influence of Culture and Politics<br />Politics  number of governments are making it more difficultto regulate fishing in some areas because of the detrimental effects they would have onnation economies<br />a loss of jobs, factories<br />Culture Many cultures around the worlddepend in marine life as one of their main food sources, mostly as a cultural preference andgeographic necessity<br />

7.
Future Price of Fish<br />rapid growth in demand of fishand the depleting amount of fish available, the price of fish is increasing faster than meat<br />

8.
What is affecting marine life the most: Humans or Nature?<br />Nature does have its natural hazardous effects on marine life but humans are what effect marine life the most<br />We overfish the sea and we pollute it<br />

9.
Factors involved in the Issues<br />The most detrimental factor is overfishing<br />Populations are dropping so fast that theremaining fish cannot reproduce enough to sustain themselves<br />overall rate of fishthrown away because they do not reach the standards of weight or size is 25%<br /> 84%of shrimp trawls are discarded<br />this does not mean back in the ocean, the marinelife that is discarded has been caught and died already<br />Fish produce more eggs the older and larger they are, reproduction rates have fallen because only juvenile fish remain<br />

10.
Aquaculture<br />help stabilize natural fisheries<br />compensate for the enormous amount of fish consumed by the world<br />negative effectshowever have to do with these fish escaping into real populations<br />chemicals put in the water of the fish to promote their quick growth<br />

11.
Government Regulations: Viable?<br />Yes it is. This is one of the most recommended solutions<br />By restricting some areas of fishing andonly allowing the unrestricted areas to be fished, populations have been proven to bothgrow in the untouched areas and even the areas allowed to be fished<br />

12.
Human Help<br />Stop the over-exploitation of fish habitats<br />Proper use of boating equipment when going near reefs, as in avoiding destroying themwith propellers. This also includes proper use of oils & fuels, filling the tank withoutspilling for instance <br />More eco-friendly boating<br />Stopping water pollution by avoiding dumping trash, fuel, and other hazardous material inbodies of water<br />
