Some economic aspects of pink shrimp farming in Florida. 



Proc, Gulf Caribb. Fish. Inst., 23d Annu. Sess., Nov. 11, 1970, 



pp. 113-124. 



Using estimated cost data, specified assumptions, three sizes of 



farms (100, 500, and 1000 acres) , two kinds of output (bait ana 



food shrimp), six prices of land ($250 to $15,000 per acre) and 



other information, the authors compute and show internal rates of 



return (IRR) , along with tables of net cash flows (and 



computational components, namely capital and operating costs with 



some detail, and gross revenue) for 16-year hypothetical 



operating periods. Economies of scale are apparent. Labor is a 



significant cost. Only two of the six operations proved 



profitable, given the land prices and crop prices assumed. kith 



higher food shrimp prices (72 cents per pound assumed for 



36-count shrimp) the situation might De less pessimistic. 



However, increasing the number of crops from one to three 



(110-count instead of 36-count shrimp) did not improve profits. 



Market price effects are discussed and would be significant for a 



large (1,000-acre) bait-shrimp farm. [Annotator's note: for
