Callinectes sapidus Rathbun, and preliminary experiments on craD 

 molting are described. The most important result was the 

 inducement of out of season molting (January-March) in the 

 Delaware Bay area. By developing methods to molt blue crabs in 

 the winter the soft shell industry can be pursued throughout the 

 year. In addition, by inducing molting the year round, faster 

 growth rates are realized and market size crabs can be obtained 

 much guicker. It is concluded that the reported work, along with 

 that of other researchers, establishes the feasibility of the 

 procedure in a technical, not economic sense.

This report shows the potential merits of utilizing heated 

 seawater frcm nuclear or fossil-fueled energy centers (power 

 stations or desalting plants) for intensive aguaculture. An 

 evaluation is made of an intensive aguaculture facility using 

 shrimp as a model since more biological, technical, and marketing 

 data are availaole for this aguatic species than for any other 

 marine life. The analysis includes a conceptual design based on 

 present technology, a cost estimate of a facility sited at an 

 United Arab Republic energy center, cost sensitivity studies of 

 the facility, and a brief market study that indicates the future 

 export market potential of shrimp to industrialized nations. 

 Capital and annual operating costs for the facility are shown, 

 along with graphed functions for the sensitivity analysis which 

 shows the effects of changes in land improvement costs, food 

 conversion ratio, wage rates and labor productivity, price of 

 product, and shrimp yield on annual production cost. 

 Subject descriptors: 



Shrimp; United Arab Republic; revenue; costs; returns; markets; 

 sensitivity analysis; engineering design; powerplant heat use.
