| Abstract |
The chemical dynamics of sea food waste decomposition and of salmon decomposition in a marine system were studied. A drastic increase in NH4(+)-N and decrease in O2 occurred in the marine bay (Iliuliuk Bay, Unalaska Island, Alaska) receiving sea food processing wastes. A seaward decreasing but elevated NH4(+)-N suggests that this bay influences the nitrogen economy of the adjacent ocean. Salmon carcasses decomposition was followed in a spawning stream and its associated estuary (Little Port Walter, Alaska). Concentrations of NH4(+)-N and organic-N in the water were determined in this system weekly, beginning before spawning and ending several months later. NH4(+)-N and dissolved organic-N in the stream and estuary were low and unvariable before spawning. During spawning, NH4(+)-N and organic-N increased downstream. As carcasses increased the WH4(+)-N) and organic-N became greater. Large increases of organic-N in the stream and estuary also resulted from salmon decomposition. (WRSIC abstract) |
