What effect removing so much krill will have on the rest of the food web?

Krill is the basically bottom of the food chain only eating phytoplankton itself and by removing a large number of it fish and other animals what eat it will not have enough food and some will die off.
there for animals above a fish like the leopard seal and penguins will have less food so a large proportion of them will die out. you then get to the top of the food chain where a smaller toothed shark will not have enough food so there numbers will decrease.
however an animal such as larger carnivorous plankton would thrive more as there would be less competition from the krill to eat the phytoplankton. then the squid which eats the carnivorous plankton will have more food so there will be more squid around and a sperm whale which eats squid will also have more food so will thrive.
so as you can see with most food webs taking out one animal which is both prey and predator will have two opposite effects.
