Gordon-

How brackish are we talking about?  I will also find out over the next 

couple of days the lowest salinity water that denis have been raised in (I'm 

used to their culture in seawater but i know they can be cultured in less 

salty waters and can stand treatment with freshwater for at least limited 

exposures (we used this as treatment for both cryptocaryon & monogeneans).

Mohammed,

I seem to recall an attempt to launch a facility to produce grey mullet 

juveniles in Egypt.  Do you know the current status of this project?

This is a reminder that The University of the Virgin Islands is offering a

short course on aquaponics and tilapia aquaculture this summer. The

announcement is also on the WWW at the following address

http://rps.uvi.edu/AES/Aquaculture/UVIShortCourse.html  Our homepage address

is:  http://rps.uvi.edu/AES/aes_home.html 

Since our last announcement it seems that several new people have joined the

list. With this course we will not only answer many of your questions, but

we will describe the range of options that exist setting up aquaponic

systems and the principles that you need to know for efficienct operation.

By the end of the course you will able to design a commercial-scale facility

and write a business plan.

Plus you will get plenty of hands-on experience as you will be charged with

running 14 systems as part of your training.  Jim R.

UNIVERSITY OF THE VIRGIN ISLANDS

AQUAPONICS AND TILAPIA AQUACULTURE SHORT COURSE

July 11-17, 1999

Program

A 7-day course that will provide in-depth knowledge of the principles

and practical application of the aquaponic and greenwater tank culture

systems that have been developed at the University of the Virgin

Islands.  Participants will be introduced to a variety of system designs

using hydroponic plant culture (aquaponics), suspended growth processes

(greenwater tank culture), or rotating biological contactors and

settling or filtering of solids for maintaining water quality.  Fish

production instruction will be conducted using both the Nile tilapia

(Oreochromis niloticus) as well as the Florida Red tilapia.  Hydroponic

plant production will focus on lettuce, but will also cover many other

vegetables as well as culinary and medicinal herbs and ornamental

flowers.

     Aquaponic system

        System design and management

           Components

           Breeding

           Fry sex reversal

           Fingerling rearing

Instruction

Each day will include a half-day of classroom lecture and a half-day of

hands-on field work.  Participants will learn the technology through

presentation of the theory and practical skill development.  Each

student will be given a notebook of reference materials.  Water quality

labs will cover the standard methods of analysis and the use of water

quality test kits.  Field work will include fish handling, vegetable

production and system operation.

Facilities

UVI is located in the heart of beautiful St. Croix.  The Aquaculture

Program operates 12 research-scale systems (6 aquaponic and 6

greenwater) as well as a commercial-scale aquaponic system, a greenwater

demonstration system with vegetable garden, a fry sex-reversal system, a

recirculating system for fingerling rearing and a purge system.  The

program produces about 20,000 lbs. of tilapia annually and more than

1,000 cases of vegetables.

Cost

This course will cost $985.  The fee covers course materials, dorm room

on campus for 8 nights (July 10-18), graduation banquet and a sailing

trip to Buck Island National Park for a day of snorkeling amid

spectacular coral reefs.  Meals cost $3-6 each at the school cafeteria.

Airfare to St. Croix, USVI is not included in the registration fee and

should be arranged separately by each individual.

Registration

Register by contacting Dr. James Rakocy at the address below.  Please

provide name, address, telephone and fax numbers, e-mail address and a

brief description of background and experience with tilapia production

and/or hydroponics.

Enrollment is limited.  A $300 deposit, payable to the University of the

Virgin Islands, is necessary by June 15, 1999 to reserve your place in

this course.  The balance will be due the first day of class.

I just wanted to pitch in my 2cents worth.  If anyone on the list can afford

the tuition and the time to attend the course Jim is offering here, I would

highly recommend it, if that means anything to this group.

Although I have never visited the UVI station, I have kept track of Jim's

publications from the get go, and his continuing efforts in this field....I

occasionally correspond with him privately.  I applaud and endorse the

spirit of investigation, experimentation and efforts at perfecting

aquaponics that his group is working toward, and Tom and Paula are working

toward, and Gordon Watkins, and the list goes on....

This is happening on many fronts in both commercial enterprises, mom and pop

hobby systems, schools, and academia.  It's all good to me, even if mistakes

are made, we can still learn from the design approaches...which vary widely.

Good Luck and God Speed.

Ted.

Hello dear Aquapioneers,

Well- the time has come for me to take the big leap and begin my little

aquafarm.

I would be an indenturered servant (just kidding , I'm not that old for false

teeth) to anyone who would be willing to share some real numbers (P&L) with me.

I am basing my numbers on factors here in CA and  I realize the variables.  I

would really like to hear from some of you that have been at this for a little

while.  Please let me know and we can chat off  line or by phone.

Always Greatful

Craig Prince

P.S. Maybe my alias could be "The AquaPrince"  ;-)
