Tujuan penelitian ini adalah untuk mengetahui pengaruh kejut salinitas terhadap pemijahan tiram. Rancangan acak lengkap diterapkan pada penelitian ini dengan empat perlakuan yaitu peningkatan salinitas secara mendadak 2‰dan 4‰ dari salinitas awal (30‰) dan penurunan salinitas secara mendadak 2‰ dan 4‰dari salinitas awal (30‰), dan tiga ulangan.

Kata kunci: Kejut salinitas, pemijahan buatan, tiram, Crassostrea cucullata The technique of oysters ( Crassostrea cucullata Born) spawning stimulation in artificial environment was important aspect on development of its hatchery technology. Consequently, research about spawning stimulation of oysters using shock of salinity has been conducted from August to October 2010. The aim of this research was to find out the effect of salinity shock on oysters spawning. Randomized design was applied in this research with four treatments, i.e. sudden increase of salinity 2‰ and 4‰ from initial salinity (30‰) and sudden decrease of salinity 2‰ and 4‰ from initial salinity (30‰), with three replications. Oysters used in this experiment were collected from intertidal of Oebelo Village, Kupang regency. Result of Kruskal Wallis test showed that salinity shock was significantly affected (P<0.05) on oysters spawning. The treatment of salinity shock with sudden decrease in salinity was trigger spawning oyster higher than the treatment of salinity shock with decrease of salinity suddenly. The highest number of oysters spawning occurred at shock of salinity treatment with decrease of salinity suddenly 4‰ from initial salinity (30‰).
