biomasses

Furthermore, due to natural variability in the size of recruiting year classes, increases in stock biomasses of the various species are most likely to occur in a stepwise fashion and the value of the catch would not necessarily increase proportionally.

All of the extra carbon that was in the atmosphere of the Mesozoic era was sequestered in the land and ocean biomasses at the time and turned into oil and coal and natural gas.

In the early 1970s, the highest biomasses occurred in the mid-shelf area, southeast of the Pribilof Islands.

The magnitude of these changes will, however, be no less dependent on the success of future fishing policies in enlarging stock sizes in general and spawning stock biomasses in particular, since the carrying capacity of Icelandic waters is probably about two to three times greater than that needed by the biomass of commercial species in the area at present.

In comparison, seasonal sea ice normally has lower densities and lower biomasses and tends to support more simple communities.

Because a lot of the biomasses take a lot of energy to produce.

High-abundance lake trout populations have biomasses of only about 2 to 4 pounds per surface acre (about 2-4.5 kg per ha), while the most productive trout streams with rainbow or brown trout can sustain an abundance of 500 pounds per acre or more (560 kg per ha).
