Overfishing in the Gulf of California has led to the depletion of many fish populations and disruption of the marine ecosystem. The gulf supports over 700 species of fish and is an important food and economic source for nearly 6 million people. However, unsustainable fishing practices like catching too many adult fish and excessive bycatch have reduced fish populations by 52-90% in many areas of the gulf. This overfishing threatens the livelihoods of coastal communities and the health of the ecosystem. Stronger enforcement of fishing regulations and monitoring is needed to promote sustainable fishing and protect the Gulf of California.

Ocean overfishing is simply the taking of wildlife from the sea at rates too high for fished species to replace themselves. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction by the mid-1900s.
These topic contains global scenario of aquaculture, demand consumption scenario and present status of aquaculture in India. These presentation also contain constraints, future prospects and challenges in aquaculture. Different aquaculture practices throughout the world.
Marine protected area Marine protected areas (MPA) are protected areas of seas, oceans, estuaries or in the US, the Great Lakes .[2] These marine areas can come in many forms ranging from wildlife refuges to research facilities.[3] MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources.[4] Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations (such as with the Phoenix Islands Protected Area), MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish.[5]
On 28 October 2016 in Hobart, Australia, the Convention for the Conservation of Antarctic Marine Living Resources agreed to establish the first Antarctic and largest marine protected area in the world encompassing 1.55 million km2 (600,000 sq mi) in the Ross Sea.[6] Other large MPAs are in the Indian, Pacific, and Atlantic Oceans, in certain exclusive economic zones of Australia and overseas territories of France, the United Kingdom and the United States, with major (990,000 square kilometres (380,000 sq mi) or larger) new or expanded MPAs by these nations since 2012—such as Natural Park of the Coral Sea, Pacific Remote Islands Marine National Monument, Coral Sea Commonwealth Marine Reserve and South Georgia and the South Sandwich Islands Marine Protected Area. When counted with MPAs of all sizes from many other countries, as of August 2016 there are more than 13,650 MPAs, encompassing 2.07% of the world's oceans, with half of that area – encompassing 1.03% of the world's oceans – receiving complete "no-take" designation.[7]
BRDs have been developed through intensive research, taking into consideration the characteristics of the fishery and geographical peculiarities.
There has been a significant reduction in the world bycatch levels during the past two decades due to the increased use of BRDs in trawling.
Cooperation among the fishing industry, scientists and other stakeholders is fundamental for the success of bycatch management efforts.
BRDs, most appropriate to the regional fishing conditions should be adopted and enforced legally to ensure long term sustainability and biodiversity of the fishery resources.

Coral reef Threats, conservation and Restoration.pptxVIRENDRA KUMAR
Coral reefs are some of the most diverse ecosystems in the world. About 25% of the ocean's fish depend on healthy coral reefs. Unfortunately, coral reef ecosystems are severely threatened. Some threats are natural, such as diseases, predators, and storms. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Saving and restoring the world's coral reefs requires a multi-pronged approach that ranges from the local to the global level.
Virtual population analysis (VPA) is a cohort modeling technique commonly used in fisheries science for reconstructing historical fish numbers at age using information on death of individuals each year. This death is usually partitioned into catch by fisheries and natural mortality. VPA is virtual in the sense that the population size is not observed or …

This presentation shows what is aquaculture, the different methods of aquaculture, and why aquaculture is important. Aquaculture benefits the oceans, economy, and environment. It maintains the health of our oceans, lessens the severity of overfishing, and reduces the transfer of diseases in sea creatures. It is a form of agriculture for those regions with poor soils and farming lands. In addition, aquaculture improves the health of the people by incorporating seafood into their diet.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Overfishing is a process in which too many fish
are caught and results in the depletion of the
population of fish which then leads to the
disruption in the system it cannot support. This
process can result from a number of different
ways.
Catching too many adult fish that cannot
reproduce fast enough.
Pirate fishing (illegal fishing)
Exceeding the carrying capacity a fishery
cannot handle.
Massive bycatch of juvenile fish.
Destructive fishing practices.
3. Overfishing leads to many problems such as endangering the oceans
ecosystem as well as the future for people who rely on seafood as a food
and economic source. The global fishing fleet is 2-3 times larger than what
the ocean can support.
• Unsustainable Fishing:
90% of the worlds fisheries are being
exploited or overfished. This is the leading
threat to ocean life and marine habitats.
Countless unwanted fish and other
animals die from these fishers.
• 52% of the worlds fisheries are
exploited, 32% are completely
overexploited, depleted and are
currently trying to recover from this
strain.
4. This is a GLOBAL problem. We will be focusing on the Gulf of California
Here are a few examples:
• Southern Chile
• Coastal East Africa
• Arctic
• The Grand Banks
• Irish Sea
5.
6. • Pacific Ocean
• Made up of Northern, Central
and Southern regions of the
Gulf.
• Approximately 700 miles of
coast.
• 37 islands that play vital roles
in flora and fauna life.
• One of the largest marine
ecosystems in the world.
• UNESCO World Heritage Site
• State Party is Mexico
7. • The Gulf of California has been known as the aquarium of the ocean. Its
abundance of various marine animals such as 170 different sea birds, over 700
species of fish and a breeding ground for many other marine animals. Not to
mention a seawater highway for migrating animals. However, commercial fishing
is starting to take its toll on this stretch of waters early in the 1950’s.
• Early protection from the Audubon Society in the 1950’s and 60s to start studying
areas of coast and islands of the Gulf. In 1962 the Mexican government granted
protection towards efforts of conservation, called Marine Parks.
8. How does this problem affect
people????
Overfishing creates a problem for
people on a global spectrum. Coastal
cities or small towns that depend on
local fishing can be deeply affected by
overfishing. For the Gulf of California
the ecosystem is suffering from this
act, which then effects its residents.
• Nearly 6 million people are
estimated to depend on fishing for
food and means of support.
9. • 75% of Mexico’s total annual fish catching is done in the Gulf.
• Due to overfishing it has decreased the population of many marine
species. This leads to a significant problem for people as well as the
ecosystem.
10.
11. • MSC-certified seafood products.
This means people are buying a
product that is certified by the
Marine Stewardship Council that
only support sustainable fishing
practices.
• Safe catch limits.
• Controls on bycatch.
• Protection of habitats all serve
as environmental correctors.
• Most importantly one of the
biggest ways to fix the issue is
stronger monitoring of oceans
and resilient enforcement of
protection laws.
