A Pioneering Study of Integrated Mariculture in Hong Kong: Simultaneous Cultivation of Commercial Species of Seaweed, Scallops and Fish to Improve Seawater Quality and Maximize the Yield of Fish Farms  

Project Title: A Pioneering Study of Integrated Mariculture in Hong Kong: Simultaneous Cultivation of Commercial Species of Seaweed, Scallops and Fish to Improve Seawater Quality and Maximize the Yield of Fish Farms

Applicant: The Hong Kong University of Science and Technology

Total Approved Grant: $1,092,800 (Actual Expenditure is $880,446.99)

Duration: 01/01/97 to 16/12/99

Project Status/Remarks: Completed

Scope: To develop a multi- species culture model using simultaneous cultivation of commercial species of seaweed, shellfish and fish; to convert the organic pollutants released by fish farms into biomass of commercially important scallops and algae which would be used for abalone food; and to develop within 2 years a balanced farming model applicable to Hong Kong waters.

Summary of the Findings/Outcomes:
The project proponent demonstrated that algae removed nutrients from seawater and that scallops and fishes released nutrients, both data sets were necessary pre-requisites to building an integrated management model. Some oceanographic field measurements were also undertaken.
