The correct answer is: C. two in the southern hemisphere only and one in the northern hemisphere.
The three recognized major fishing grounds of the world are:
- The North Pacific, which is located in the northern hemisphere.
- The South Pacific, which is located in the southern hemisphere.
- The South Atlantic, which is located in the southern hemisphere.
The North Atlantic is not considered a major fishing ground because it is not as productive as the other three.
The North Pacific is the most productive fishing ground in the world, accounting for about 40% of the world’s total catch. The South Pacific is the second most productive fishing ground, accounting for about 25% of the world’s total catch. The South Atlantic is the third most productive fishing ground, accounting for about 15% of the world’s total catch.
The productivity of a fishing ground is determined by a number of factors, including the abundance of fish, the size of the fish, and the availability of food. The North Pacific is the most productive fishing ground because it has a large abundance of fish, including tuna, salmon, and halibut. The South Pacific is also a productive fishing ground because it has a large abundance of fish, including tuna, swordfish, and marlin. The South Atlantic is not as productive as the other two fishing grounds because it has a smaller abundance of fish.
The fishing industry is a major economic activity in many countries around the world. In 2018, the global value of the fisheries and aquaculture sector was estimated to be \$2.4 trillion. The fishing industry employs about 50 million people worldwide.
The fishing industry is facing a number of challenges, including overfishing, climate change, and pollution. Overfishing is the removal of fish from the ocean at a rate that is faster than they can reproduce. Climate change is causing changes in the ocean environment, which is affecting the distribution and abundance of fish. Pollution is contaminating the ocean, which is harming fish and other marine life.
The fishing industry is important for the global economy and for the livelihoods of millions of people. It is important to manage the fishing industry sustainably so that it can continue to provide food and economic benefits for future generations.
