Why are clupeiform fishes economically important to world fisheries?

Clupeiform fishes—which include herrings, sardines, anchovies, pilchards, and menhadens—are among the most economically significant fishes in the world. Approximately 20 species alone account for more than one-third of the total global fish catch, making this order the most heavily exploited of all fish groups.12

Their economic value is primarily driven by their high abundance, which is determined by several key ecological factors:

• Dietary Habits: Economically important species are typically plankton feeders. Predatory clupeids are generally scarcer and hold less commercial value.3
• Geographic Range: Species that inhabit vast areas and possess highly migratory behaviors, such as the Pacific sardine and Atlantic herring, are particularly valuable to commercial fisheries.3
• Reproductive Strategies: High abundance is often linked to early sexual maturity or, in some cases, precocious breeding within restricted habitats.3

Because these biological traits directly dictate population size and distribution, they are the focus of extensive study to ensure the efficiency and sustainability of global fishing efforts.34
