I think they are too small to get caught in the nets.
Add to that, a single Blue whale eats over 3 tonnes of them a day, other Baleen whales eat them too so there's got to be a lot of them out there. It would be very unlikely that, even if we tried, Humankind could have any impact on krill populations at all.
If it did happen, however, one possible outcome would be an increase in plant plankton and algae in the oceans leading to a decrease in ocean oxygen and all marine life. This could lead to a "major extinction event". Something similar is believed to have happened to trigger the "Permian-Triassic exticntion event" (or at least part of the reason).
The rate at which they are being eaten would not be greater than the rate at which they are decomposing, in other words they would die of old age and rott in the bottom of the ocean. Bacteria would eat the plakton and take the oxygen form the surrounding waters. These waters would then be lethal to any nearby swimmer, or to an entire ecosystems. Planktons are critical to an ecosystem. I like plankton.

If krill decreases what will happen to the food chain in Antarctica?
After all the krill is gone, the whole food chain will go down.
What would happen if Krill disappeared in Antarctic?
Then alot of animals would be hungryAnother AnswerAntarctic Krill form the base of the food chain in the Southern Ocean. Without them, the animals in that food chain would be forced into warmer water for food, where they may not survive, based on their invasion of a different food chain.
What would happen if krill overpopulated the ocean?
there predators would become over populated and couse a major mix up with the food chain of the ocean.
What would happen if bacteria were taken out of the food web?
The good web would collapse
What would happen if a bunny was taken out of a food chain?
the fox will decrease its numbers
What would happen if one of the animals in the African lion food chain was taken away?
never do
Does any animal in the coral reef eat krill?
yes, of course they do. Without krill, then many animals would have less food.
What effect would a drop in the size of the of the krill population have on the Antarctic food web and why?
Euphasia superba, Antarctic krill, are the base of the food chain in the Southern Ocean that surrounds Antarctica.Any decline in their population would mean that the remainder of the food chain would be forced into warmer water to find food.
Are krill producer?
No, krill are primary consumers, they eat producers (phytoplankton).
What is an Southern whales food chain?
a food chain is a chain about a whale what a whale eats is a krill for e.x whales eat krill,krill eats phytacton
What eats the most krill in Antarctic waters?
Antarctic Krill form the base of the food chain in the Southern Ocean that surrounds Antarctica. All sea animals feed on krill.
Is krill a producer?
No Krill is not a producer because, it does not make it's own food.
