Effects of Stocking Density on Survival of Laboratory Cultured Summer Flounder 'Paralichthys dentatus' Larvae

摘要

Studies are being conducted to determine standard laboratory culture conditions for rearing summer flounder larvae to be used in toxicological bioassays. Experiments were conducted using the type of container and physical conditions use in the long term chronic toxicological bioassays. Possible causes of increased mortality and developmental abnormalities at increasing stocking densities are discussed. Optimum density in the 6 liter closed system was about 20 fish per liter.
