In this case, the spring bloom occurs later, water column temperatures are warmer, and higher zooplankton production provides prey for larval and juvenile fish. Bulls become sexually mature between 3 and 8 years of age, but typically are not large enough to hold territory successfully until 9 or 10 years old. Scientific Classification.

Sediment respiration rates, which indicate carbon loading to the seafloor, have also declined since the late s. In this case, the spring bloom occurs later, water column temperatures are warmer, and higher zooplankton production provides prey for larval and juvenile fish.

The transport of nutrients from the oceanic waters occurs in the Shelikof Strait with the mixing of fresh water and seawater as the ACC flows seaward Reed et al.
