pls i need sites that offer good books on poultry, catfish production,
ornamentals, and general farming procedures and these sites must be
able to ship to south africa, ghana, nigeria and tunisia.

I have myself ordered lots of English-language books on different
agricultural and aquaculture subjects from online booksellers in the
United Kingdom.  I have usually ended up using amazon.co.uk
(http://www.amazon.co.uk/), as they seem to have the most extensive
availability - they even direct you to sellers of used books. 
Amazon.co.uk are able to ship any country in the world.

Another excellent bookseller is WHSmith (WHSmith.co.uk), but their
prices are usually a bit higher than Amazon.co.uk's.  WHSmith also
ship books worldwide.

I have compiled a list of links to these shops' category listings of
books in each of the mentioned subjects.

Poultry farming:
http://www.amazon.co.uk/exec/obidos/tg/browse/-/922504/ (973 titles available)
http://www.whsmith.co.uk/whs/Go.asp?BIC=bTVH (enter "poultry" in the
search box - 31 titles are available)


Catfish production:
http://www.amazon.co.uk/exec/obidos/tg/browse/-/277870/
http://www.whsmith.co.uk/whs/Go.asp?bic=bTVT

Go to this category and enter "catfish" in the "Search in Fisheries"
field - the search returns 7 titles, of which 2 are available for
ordering: "Recent Developments in Catfish Aquaculture" and "Channel
Catfish Farming Handbook"


Ornamentals:
http://www.amazon.co.uk/exec/obidos/tg/browse/-/271780/ (201 titles available)
http://www.whsmith.co.uk/whs/Go.asp?BIC=bVGPC (flowers, 198 titles)
http://www.whsmith.co.uk/whs/Go.asp?BIC=bVGPS (shrubs and threes, 138
titles available)


General farming procedures:
http://www.amazon.co.uk/exec/obidos/tg/browse/-/570586/ (general
agriculture & farming, 1816 titles)
http://www.amazon.co.uk/exec/obidos/tg/browse/-/570570/ (agricultural
science, 961 titles)
http://www.amazon.co.uk/exec/obidos/tg/browse/-/277885/ (tropical
agriculture, 318 titles)
http://www.whsmith.co.uk/whs/Go.asp?BIC=bTV (this category contains
all Agriculture & farming titles - currently 3382 in total)


When you find the books you want, I'll suggest that you use the
BookBrain service at http://www.bookbrain.co.uk/advsearch.asp to
determine prices at different bookstores.  You might find that the
books you want can be obtained for a lower price at some other
bookstore than those I have listed here.


I hope this answer provides the information you need.  If not, please
request an answer clarification.

My answer is a bit inaccurate for the catfish production section.  The
listed procedure works well at amazon.co.uk, but for whsmith.co.uk you
should rather enter "catfish" in the "Search for an author or a title
within this department" search box.

Alsp, please note that the category listings at WHSmith will initially
show only the bestsellers within each category.  If you wish to see
all the books, use the " Click to see the full list!" links.
