Jellyfish compete with anchovies for plankton, and are prayed upon by tuna and swordfish, which might benefit jellyfish. Would it be increasing swordfish increase in anchovies, increase in tuna, or increase in plankton

Increasing the population of swordfish would likely lead to a decrease in the population of anchovies, as swordfish prey on anchovies. This could potentially result in an increase in the population of plankton, as anchovies compete with jellyfish for plankton as a food source. It is unlikely that an increase in swordfish population would directly benefit jellyfish, as swordfish also prey on jellyfish.
