Editor Larry L. Booda reported, "In 1975 the nag pete A Sake ee

to the optimum and thus would be the proportion tor commercial oper- 
ations. ... CGurrent state-of-the-art oysters grown at U.D. show 
this comparison -- a palm size natural oyster that took three years 
to grow matches a cultured one that required one year, ae Mts lab- 
oratory oyster has twice as much meat. Dr. William S. ait ah 
Dean of the Center, estimates that, if funding by the National Sea 
Grant Program is continued as requested, closed cycle oyster cure 
ture should become commercially viable in one or two years. 
Now, within the time projected by Dr. Gaither, we have the follow- 
ing news item, sent to us by Ed Cowles, from CHEMICAL ENGINEERING 
of February 26, 1979: 
Oyster plant far inland will use "Yartificial™” seawater -- 
Marine Nutritional Systems Inc. (Denver) is building a 10-million- 
oyster/yr facility in Lamar, Colo., which is expected to be com- 
pleted by mid-summer. While many large companies are now actively 
involved in aquaculture research, Marine Nutritional claims that it 
is the only one to be commercializing a closed recirculation system, 
using water that simulates all the properties of seawater. 
The warm-water requirements for optimal growth conditions (about 
75°F) will be met by using "waste heat" from the steam of the stand- 
by boiler of the Lamar power plant, which is adjacent to the oyster 
facility. 
Shrimp will be a salable byproduct; they will be stocked in the 
tanks with the oysters to consume oyster wastes. 5

WANTED: A SUMMER SCIENCE JOB, AND MOLLUSKS OF LONG ISLAND SOUND 
"I am 17 years old and have been involved in Marine Biology and mala- 
cology for six years. I have participated in many activities involv- 
ing molluscs and biology such as shell lecturing for area school 
systems, extensive summer courses in marine biology and an indepen- 
dent study course concerning the molluscs of Long Island Sound. 
Next year I am going to college and this summer I would like to get 
a job dealing with science, preferably biology. Anyone having in- 
Hens pifand! toy aoe tee aae in science please contact 
5 ic Dolan iar Brae :

Also, I would like to purchase Long Island Sound molluscs for the 
independent study project. I need Acmaea testudinalis, Epitonium 
rupicola, Crepidula convexa, Crucibulum striatum. Bupleura caudata 
Buccinum Orin ne Ovatella myosotis and many more. Roars ie 
such shells they want to sell please contact me."
