ABSTRACT The effects of API reference South Louisiana crude oil upon four larval stages of American lobster (Homarus americanus) were determined in a flow-through system. Tests were conducted with naturally-hatched animals in individual test chambers as well as in mass culture systems in an operating state lobster hatchery. Experimental flow-through crude oil exposure concentrations were 0.1, and 1.0 ppm, administered as a strongly-agitated emulsion-like mix to ambient temperature seawater ranging from 15°-20°C. Oil exposure residence times ranged from 0.8-5.6 minutes depending on the test. Exposed animals were monitored six times daily for feeding behavioral characteristics, mobility, molting success, growth and development times to reach the fourth larval stage. Pigmentation analysis was performed on individual larvae by photomicroscopy, and hydrocarbon analyses were also conducted thereon. Post-larval development through the eighth stage was investigated. Statistical comparisons were made among different control animals and between control and oil-exposed larvae.

Lc50 Value

The acute toxicity to P. quadridentatus, of Kuwait light crude oil, BP/AR dispersant and an oil-dispersant mixture was determined. Observed 96-h LC50 values averaged 1555 mg 1-1 for oil added to water. A statistically valid 96-h LC50 value for the dispersant was not obtained, but results indicated that a solution containing between 1300 and 2200 mg I-1 might be expected to produce 50% mortality. A mixture of oil and dispersant in the ratio 4 : 1 gave an observed 96-h LC50 value of 96 mg 1-1, a 16-fold increase in toxicity over oil alone. The implications of the results are discussed.
