Adaptation of a Brown Water Culture Technique to the Mass Culture of the Copepod Acartia tonsa

The use of bay water, filtered to 5 microns, was found to be sufficiently nutritious to sustain an average of 232,000 adult Acartia tonsa per m3. Copepods survived up to 24 days as adults and produced up to 75 nauplii per adult. Nauplii could be sieved to produce copepods of known age or known parentage. Survival of nauplii to adults ranged from 15 to 88%. Culture water varied from 6 to 28oC in temperature, and from 1 to 26 ppt in salinity.
