How Much Fish Resides In The Vast Pacific Ocean?

Have you ever wondered about the staggering number of fish residing in Earth’s oceans? Well, scientists have made remarkable estimates, suggesting that a mind-boggling 3.5 trillion fish call the world’s oceans home. This astonishing figure, last updated in July 2022, helps us comprehend the immense biodiversity that thrives beneath the waves.

The Pacific Ocean is renowned for its incredible abundance of fish, making it the primary source for more than 70 percent of the world’s total fish catch. This vast body of water, covering approximately one-fifth of the Earth’s surface and boasting a coastline stretching over 111,866 kilometers, plays a crucial role in global fisheries. On the other hand, the North Atlantic Ocean stands out as the saltiest region among all the world’s oceans. It contributes significantly to the global fish supply, accounting for about 20 percent of the total catch. These statistics highlight the pivotal role that the Pacific and Atlantic Oceans play in sustaining the world’s fishing industry, ensuring a steady supply of seafood to meet global demand.

When examining the composition of ocean life, it becomes evident that fish make up a relatively small portion. The vast majority, approximately 98%, of ocean biomass consists of microorganisms. Among the larger organisms inhabiting the oceans, you’ll find a significant presence of mollusks and arthropods, including crustaceans. This prevalence of various marine life forms leaves fish accounting for only a small fraction of the remaining 2% in the ocean’s overall biomass. Therefore, the percentage of the ocean occupied by fish is relatively modest in comparison to the diverse range of other aquatic organisms.
