Chilled fish

We are buyers of fresh seaproducts in the South of Russia.
We supply with fish products the restorants in Sochi, Krasnodar, Rostov, Stavropol.
We are seeking for cooperation with Turkish companies who can supply us with fresh fish and deliver it to Novorossisk or Gelendjik (by Ferry).
Now we are interested in buying Sea Bass, Dorade etc. around 500-1000 kg per week for summer season.
But this quantity can increase considerably.
Please advise your possibilities and interest.
