As a new type of marine operation platform and aquaculture model, the deep ocean aquaculture engineering ship has received extensive attention in the field of marine engineering and marine aquaculture. At present, China still lacks relevant technical and economical verification systems for the refitting and construction of aquaculture engineering ships. In this paper, based on the argumentation parameters, the main scale model for reconstructing the bulk carrier ship type was established using the linear regression equation; the economic model was established with the farming effect coefficients, investment payback period, and net present value; the technical-economic performances of the ship type technology and economic multi-target ship type scheme were calculated by the parametric analysis method, thus to select the best scheme among them by comparison; sensitivity analysis was carried out on the uncertain factors such as the survival rate and the annual aquaculture cost. Thus VB programming technology can be used to develop a technical and economical demonstration system for aquaculture engineering ships based on the technology and economics demonstration model. Through the simulation calculation, the carrying capacity of the ship type should be more than 30,000 tons, the fish price should not be less than 61.4 yuan/kg, and the breeding density should not be less than 36fries/m3.
