Development of aquaculture technologies for sustainable and equitable production of aquatic products in tropical coastal areas

2020-09-11

The objective of our research project is to develop safe and sustainable aquaculture technologies based on environmental conservation and the carrying capacity to improve the aquacultural environment by utilizing the local fishery resources.   And also, we aim to elucidate physiological factors controlling reproduction in economically-important shrimp species in developing regions.  The information obtained above will be applied to the development and adaptation of re-circulating production systems in developing areas.
In the mariculture of coastal areas, there occur ecological problems, including water eutrophication and sludge accumulation at the bottom due to nutrients loading from the residual diets and feces.  To address these issues, integrated aquaculture technology will be developed by improving the quality of water and sediments at aquaculture farms and their environs (Fig. 1: Integrated Multi-trophic Aquaculture (IMTA)).   A final goal is to improve the livelihood as well as increase employment for small-scale farmers in local areas by carrying out the dissemination and promotion of the technologies which are beneficially suitable to the characteristics of the local aquaculture.
