regulation. The views and opinions of industry and university 

 people who were interviewed indicate that a profitable industry 

 may be operational in say 10 years, that some of the obstacles 

 are being overcome, or at least being attacked, and that even 

 now, "barring a disaster, shrimp farming can be marginally 

 successful . "

Ihe commercial crawfish industry of South Louisiana. 

 La. State Univ., Cent. Wetland Resour. , LSU-SG 74-01, 59 pp. 

 This report is an abridged version of a thesis submitted to 

 Oregon State Univ., 1973, entitled "A geographic systems analysis 

 of the commercial crawfish industry in South Louisiana." Topics 

 include history of crawfishing, biology, cultural technigues, and 

 various factors affecting processing plants and ponds, and their 

 location. Information is provided on the number, type, and 

 location of ponds, including freguency distribution graphs on the 

 number of ponds by size and type (open, swamp, and rice-field 

 ponds) . Estimated acreage of commercially managed ponds is shown 

 for selected years; and it grew from 40 acres in 1949 to 44,000 

 acres in 1973, but growth is expected to taper off. The 33 

 studied processing plants have annual input of live crawfish 

 ranging from 2,000 to 450,000 pounds, and 57% of these plants are 

 owned along with a complementary restaurant, grocery store, or 

 fish market outlet. A consensus is that 50-acre ponds maximize 

 returns on investment. Both total and per-acre estimated 

 revenue, cost, and returns are shown for a hypothetical 50-acre 

 pond operation.

The feasibility of brine shrimp production on Christmas Island. 



Univ. Hawaii, Sea Grant Progr., Sea Grant Tech. Rep., 



UNIHI-SEAGRANT-TR-73-02, 173 pp. 



Discussed is a scheme to culture brine shrimp on Christmas 



Island, the largest of the Line Islands, 1,100 miles due south of 



Maui Island in the Hawaiian Archipelago. Details on the islands 



location, weather, government, and history are given along with 



details on geology, physiography, lake circulation, and biology 



of the brine shrimp. The market potential for cultured brine 



shrimp is discussed. Aguarium hobbyists and consumers of the 



shrimp as a food source create the market. Estimated annual
