Iwashi is a Japanese term that refers to a group of small, schooling fish commonly known as sardines or herring. The word "iwashi" typically describes various species of small, oily fish that are widely distributed across the Pacific and Atlantic Oceans, particularly in the waters surrounding Japan.

In culinary contexts, iwashi is highly prized in Japanese cuisine, where it is prepared in numerous ways. It can be served raw as sashimi, grilled, pickled, or used as an ingredient in soups and rice dishes. Due to its flavorful oil content, it is valued for both taste and nutritional benefits, being a rich source of omega-3 fatty acids, proteins, and essential nutrients.

Several species fall under the umbrella of iwashi, including the Japanese sardine (Sardinops melanostictus), Pacific sardine (Sardinops sagax), and other small pelagic fish. The specific species referred to as iwashi may vary by region and context.

Iwashi also holds ecological significance as a forage fish, serving as a primary food source for larger predatory fish, seabirds, and marine mammals. Their populations can experience fluctuations due to overfishing, climate change, and environmental conditions, impacting local ecosystems and fisheries.

In summary, iwashi encompasses a group of small, oily schooling fish important both ecologically and gastronomically. Its presence is significant in Japanese cuisine and marine food webs, making it a notable species among small pelagic fish.
