low oxygen kills fish, which decompose and produce nutrients for algae
increased temperature increases waste from fish, which provide energy for algae
increased temperature and less dissolved oxygen make fish move, decreasing competition so algae can grow
Increased temperature leads to more dissolved oxygen, which helps algae grow
