N. Sakurai et al., EXPERIMENTAL CULTURE OF THE AMERICAN LOBSTER (HOMARUS-AMERICANUS) UTILIZING WARM WASTE-WATER FROM A POWER-STATION IN JAPAN, Crustaceana, 67, 1994, pp. 233-238
The American lobster was cultured experimentally at Hayama, in seawate
r controlled between 16-degrees and 20-degrees-C to investigate the ad
vantages of utilizing warm waste water from a power station. The survi
val rate was improved by using an open (flow-through) rearing system w
here the lobsters were reared under dark conditions and seawater was d
isinfected by ultraviolet light. Bacterial number was reduced from 3.4
-37.5 x 10(3) to 0.7-4.3 x 10(3) CFU/ml by ultraviolet treatment. The
rearing results were compared with those obtained at Sanriku, using am
bient seawater between 10-degrees and 20-degrees-C. Growth rate was fa
ster at Hayama than at Sanriku. With these rearing conditions at Hayam
a, the lobsters might be raised to marketable size within 3 years.
