Portunus trituberculatus is the world's most heavily fished crab species, with over 300,000 tonnes being caught annually, 98% of it off the coast of China.

It has also diminished the gazami crab's immune system which has led to the decline in its ability to fight off diseases.

These two diseases have caused a great deal of damage to Portunus trituberculatus which has created severe economic losses and deprivation to the industry.

These diseases have ultimately reduced the comfort and healthy evolution of the gazami crab's farming industry.
