Texas—Corny Mock’s Consultations in 1985


Cornelius R. Mock is a shrimp farming specialist with the USA Department of Commerce.   His services are available to countries, institutions and USA citizens at no charge; however, the party requesting his services must pay all expenses. Following are some excerpts from Mock's correspondence and trip reports:


 Letter to Ecuador's Minister of Agriculture


“As an aquaculture specialist for the United States Department of Commerce, I have had the opportunity to perform and continue to do a variety of consulting duties in Ecuador.  These duties range from assisting ESPOL chose a site and technical manager for its marine shrimp program, giving opinions on proposed sites and farms to interested USA citizens and sending information to hatcheries and farms.”


“The number of people from Ecuador requesting information particularly about hatcheries for the culture of penaeid shrimp continues to increase, while visitors and telephone calls are more frequent.  Ecuadorean farmers are concerned that there are not enough wild seedstock available or hatcheries within Ecuador to meet the demand for seedstock.”


“With the increasing demand for seedstock, more hatcheries will be built, however, the technology and people to operate these facilities must be imported.  In fact, there just are not enough trained people in the world who know how to run a hatchery, to meet everyone’s demands.  Private companies that have the technology tend to keep it a secret.  There are few places in the world today where one can go and train.”


“Ecuador needs nauplii and postlarvae now--billions just to keep present ponds stocked.  After careful consideration, it is my recommendation that Ecuador lift its restrictions and allow the importation of nauplii and postlarvae.  There are many good hatcheries in other countries with the capacity to produce 100s of millions of nauplii and postlarvae shrimp--some of the same species native to Ecuador.”



Notes to the Aquaculture Digest


“A group in Ecuador contracted with Jack Parker to buy nauplii for $4/1000 plus shipping.  These are then flown to Continental Sea Farms in Panama City, Florida, and raised to the postlarval stage for $8.00/1,000 then shipped into Ecuador (“Penaeus vannamei”), plus shipping.  I'm getting from 1-3 overseas calls a day from people trying to buy seedstock for their ponds in Ecuador.”


“By the time the postlarval shrimp reach Ecuador, they now cost about $25.00/1,000 (this includes shipping).  They must have special care and go fast.  I was just told that Ralston Purina in Panama, Central America, has been selling and shipping excess postlarvae to Ecuador.  The Panama government has just recently restricted this.  Any excess postlarval production must now be sold to shrimp farmers in Panama.”


“I have received notification...that Sea Culture, Key Biscayne, Florida, is shipping P. vannamei (postlarvae) to Ecuador from Guatemala and Costa Rico.  First shipment was 3 million at $10.00/1,000.”



Shrimp Consultation in Australia


In his Australian trip report, Mock said: “In my travels throughout the world, I hear and see many things.  People are saying that they have accomplished certain scientific feats that now have commercial application where in fact it isn't so.  Several proposals by USA companies, submitted to groups in Australia were made available to me.  Gentlemen, I was appalled at what some of you are saying.”
