SSNS Training Course 6:

Marine fish nursing techniques

Background

Expansion in the world's human population and economic development will increase future demand for marine fish products. It has been predicted that the global demand for fish for human consumption will increase by more than 50% over the next 15 years, while the existing fish caught from the wild is not enough and it does not meet the requirements. Currently, many countries are focusing on developing marine fish aquaculture and the success of marine fish propagation and larvae rearing play a keystone for the success of marine fish industry. Therefore, the techniques in marine fish nursing have been studying and developing to meet this inevitable requirement.
