Under the latter category are found such applications as abundance and spatial distribution mapping, as well as movement tracking, such as sightings of right whales, Balaenidae eubalaena, or migration patterns of yellowtail flounder, Limanda
Biologists studying Pacific walrus at these haulouts had noticed that their numbers declined over the season, coincident with fishing effort by trawl vessels targeting yellowfin sole, Limanda
aspera, in the spring once the ice sheet had retreated.

Following the fieldwork, the data were analyzed to compare sample-estimated weights to census-based weights for skates, Pacific halibut, and snow crabs (crab comparisons were based on numbers of individuals), and to compare haul-specific, daily, and total-cruise estimates based on observer samples with those based on production and discard estimates for retained species (walleye pollock, Theragra chalcogramma; Pacific cod, Gadus macrocephalus; yellowfin sole, Limanda
aspera; Alaska plaice, Pleuronectes quadrituberculatus; and flathead sole).
Interestingly, a similar problem has been encountered in trawl survey abundance estimates for an Atlantic species of flatfish of the same genus as yellowfin sole (yellowtail flounder, Limanda
ferruginea) as reported by Collie and Sissenwine (1983).
The catches ranged from low (Atlantic cod, Gadus morhua) to high (yellowtail flounder, Limanda
