Fisheries Survey
"The abundance of Catostylus mosaicus was estimated by stratified random sampling within the survey areas. Each survey area was divided into strata based on information from the previous studies of jellyfish distrubution. Within each stratum jellyfish visible in the top few meters of the water column were counted along randomly selected transects of known length and width. From these counts the mean number of jellyfish per transect and the total number of jellyfish per stratum, plus upper and lower 95% confidence intervals were estimated. Area-wide estimates of the mean number of jellyfish transect and the total number of jellyfish were also made" (Coleman 2004).
