Actuality
As the human population augments all the
time, there is a necessity in new species of
ocean fishing. The krill is the most
perspective one but its extreme catching
output
can influence negatively on the
Antarctic ecosystem.

LOGO
Antarctic environmental conditions and Antarctic
krill
The subject of my research :
The impact of interannual and global climate change on
the krill population, the impact of fishing on the krill
population

Part 1
Kill is not only a
source of high-grade
protein, but it also
contains
biologically
active substances.
Krill
biomass
is
between
200-750
million tones, but it
depends on hydro
meteorological
conditions.

11. Expected result:

LOGO
Create a mathematical model
describing interannual changes of
krill biomass. This developed model
will help to make krill fishery
rationally, to receive economical
effect without negative influence on
environment.
