As sea waters in the South Atlantic warm, the amount of krill available for seals drops, leading to a smaller yet more genetically varied population

The steady disappearance of sea ice also has led to an apparent reduction in the prime source of food for Adélies — Antarctic krill, the shrimplike zooplankton whose life history is intertwined with sea ice.

Humpback whales are known for the complexity of their feeding techniques, which include «trapping» krill and other prey within bubble nets they produce and gulping up to two - thirds their weight in prey - laden water.

Ainley says that the decline of this large, slow - growing, bottom - dwelling fish has knocked the Antarctic ecosystem out of whack and resulted in killer whales dropping in numbers, whereas silverfish have increased in abundance to compete with penguins and whales for crystal krill.

Today, even the krill are under threat from countries such as Norway, which want to use them as feed for their domestic salmon farms.

With fewer whales eating them, for instance, you would expect there to be far more krill in the Southern Ocean, but strangely there seems to be a lot less than before.

The data could help conservationists make a stronger argument for how much krill the whales need to survive.

In the 1970s and 1980s, for example, researchers argued that reducing certain whale populations would aid stocks of krill, a ubiquitous crustacean in the Southern Ocean that is a key food source for baleen whales and other marine species.

Recruitment is related to the winter sea ice cover from the previous year, as diminished sea ice cover reduces habitat available for over-wintering juvenile and adult krill and reduces the size of the food - rich marginal sea ice zone in summer.

To quantify krill biomass and distribution we used: an integrated MOCNESS [17] for estimates of krill size and acoustic target strength; dual EK - 60 fisheries echosounders (38 and 120 kHz, Kongsberg - Simrad) calibrated according to [18] and mounted on a zodiac for fine scale (100 km) measurements of acoustic volume backscattering; and the ADCP echo intensity to define the meso - scale (101 km) geographic extent of the krill distributions.
