#' @details Yellowfin Tuna were sampled onboard the vessels by observers of the Inter-American Tropical 
#' Tuna Commission (IATTC, 2004).  Fish were randomly subsampled from purse-seine sets immediately after capture, 
#' and date, position, and sea-surface temperature (SST) were recorded for each set that yielded samples.  Observers 
#' measured fork length of the fish, removed samples of white muscle tissue from the dorsal musculature adjacent
#' to the second dorsal fin and stored them at about -20 degrees C until processed further in the lab. 
#' Data is in matrix format where each row represents one YFT.
