Which key difference exists between East Pacific and West Pacific yellowfin stocks?
Answer
The East Pacific action links to coastal features, while West Pacific stocks are often found far offshore near submerged seamounts.
Although both sides of the Pacific host vast yellowfin populations, the environments where they are most frequently targeted vary significantly. In the East Pacific, populations are often associated with more defined coastal structures, such as the upwelling zones near South American countries. Conversely, the massive stocks in the Western Pacific, reflecting their broad pelagic nature, are frequently located much farther from land, often congregating around submerged seamounts where cooler, nutrient-rich waters are brought upward.
