inci - pearl

"su altýnda kullanýlan oksijen tüpü" - aqualung

(or so the dictionary says!)

I assume the literal translation is something like:
"oxygen cylinder to use under water"

  istiridye - oyster

Deniz - ocean

(I have a particular part of the sea in mind).

yüzmek = swim

kuþatmak to siege

(there is no such verb in English as ´to siege´  - the verb is ´to besiege´

Kýralýk = rented

 kiralýk - for rent

rented - kiralanmýþ

for sale - satýlýk

Oh I suppose I should have know that - I see the word often enough.  But I thought it could mean both and got this meaning from the site dictionary:

3. rented (house, apartment, office, etc.)

 pahalý= expensive

hazine - treasure
