Besides mainstays, what specific small zooplankton were noted in the diet of yellowfin near Hawaiian waters?
Answer
Copepods
Dietary studies are sensitive to local conditions and the size of the consumer. Research conducted in specific areas, such as near Hawaiian waters, revealed nuances in the yellowfin's menu beyond the major categories of fish and squid. Specifically, researchers observed that even very small zooplankton, identified as copepods, might be incorporated into the diet. This tends to occur especially when the fish are younger or during periods when larger prey items are temporarily difficult to locate, demonstrating the generalist nature necessitated by their environment.
