The researcher Li Jian from the Yellow Sea Fisheries Research Institute teamed up with Changyi Haifeng -Aquaculture Co. and Rizhao Haichen from Aquatic Products Co. developed and bred the “Huanghai No.4” prawn which features a strong resistance to high pH, fast growth and high survival rate.
Compared with “Huanghai No. 1” and “Huanghai No. 3”, this new species has an average increase of 32.2% and respectively 16.3% in survival rate under high pH (9.2). Under the same breeding conditions, the harvest weight increased by 5.1% and 10.7%, respectively, and the survival rate increased by 20.3% and 13.6%, respectively.
Since 2004, when the first prawn bred by the Yellow Sea Fisheries Research was certificated, China launched five new prawn species.
