Cik ilgi austere var iztikt bez ūdens
22, 2006, 12:27Silvija
:-:

    Par austerēm sauc virkni gliemeņu (Bivalvia) ģinšu – Ostrea, Saccostrea, Crassostrea, Striostrea. Eiropā vislabāk pazīst Ziemeļatlantijas austeres (Ostrea sp.). Dažādām sugām jau iztrurība ir dažāda. Būtiski ir arī vai tā jau ir pieaugusi austere, vai tikai mazulis. Gliemenēm ir raksturīgs tas, ka nonākot sausumā, vāki noslēdzas, to dzīvības procesi ganrīz apstājas, līdz ar to tās var pārciest ievērojamas laika posmus bez ūdens. Piemēram, John A. Nell rakstā «The History of Oyster Farming in Australia» (Marine Fisheries Review, Summer, 2001) raksta par to, ka austeru audzētājiem iesaka izņemt no ūdens un paturēt līdz divām nedēļas sausumā viņu audzētās Sidnejas klinšu austeres (Saccostrea glomerata, S. commercialis) lai atbrīvotos no Klusā okeāna austeru (Crassostrea gigas) mazuļiem.
