Abstract
  • Aquaculture of oysters has never obtained the economic importance in Oregon as it has in other coastal states. There are at present seven commercial culturists in Oregon. The two oysters cultured are the Crassostrea gigas and the Ostrea lurida. Since oysters do not naturally spawn in Oregon waters the spat, seed, must be produced elsewhere to be planted in the tidewaters. Many problems in the culture of oysters result after the larvae has attached itself to a permanent growing site, It is then easy prey for other sea life, starfish and oyster drills. In today's environment a greater danger is water pollution. The pollution changes the chemical balance of the water as well as the temperature, both of which the oyster is sensitive to.
