Houston Chronicle: A record catch of krill near Antarctica could trigger an unprecedented end to fishing season MIAMI (AP) — Trawling near Antarctica for krill — a crustacean central to the diet of whales and a critical buffer to global warming — has surged to a record and is fast approaching a never before ... A record catch of krill near Antarctica could trigger an unprecedented end to fishing season Krill are considered an important trophic level connection near the bottom of the food chain. They feed on phytoplankton and, to a lesser extent, zooplankton, and are also the main source of food for many larger animals.
Understanding the Context
Krill are small, shrimp-like crustaceans that belong to the zooplankton group. They are filter feeders that consume phytoplankton and other small organisms found in the ocean. Krill are an important food source for many marine animals, including whales, seals, penguins, and fish. Krill is a general term used to describe a group of about 86 species of small shrimp-like crustaceans found throughout the world's open oceans.

Key Insights
While they may be small — generally about the size of your thumb — they play an important role in the food web. Krill serve as integral parts of marine food chains in Antarctic waters; they are the main prey for several penguin, whale, and fish species in the region. “Since krill are creatures that play an important role in the Antarctic ecosystem for many predators, such as penguins and whales, I question as to whether we should go all the way to the Antarctic Ocean to catch krill for nutritional supplements or fishing bait.”
