crozooplankton. Production of herbivorous zooplank-ton is 72 tonnes C yr-l ; assuming a 20 transferefficiency (Parsons et al. 1977, Walsh 1981, Walsh et al.1981) 380 tonnes yr -l are required for zooplankton
food. In 1981 there w ere 1239 m2 of mussel raft s and,assuming a consumption of 0.06 tonnes C m-2 yr-', 68tonnes yr I would be consumed. Wild mussels areestimated to consume less than 10 tonnes C F-'.Phytoplankton respiration consumes a proportion ofthe available carb on, 10 to 40 OO of total carbon produc-tion (Bu nis 1980). In making the p resent calculations a

A carbon flow diagram for the Killary Harbour sys-tem is shown in Fig. 2. Symbols are taken from Odum
(1972). Particulate ca rbon inp ut to th e system is esti-mated to be: phytoplankton, 1306 tonnes C yr-l; mac-roalgae, 50 tonnes C yr-'; benthic microalgae, 51tonnes C yr- l; river carbon, 500 tonnes C F- ; makinga total of 1907 tonn es C yr-l.
This carbon is consumed by zooplankt on, wildmussels, cultured mussels, benthos, bacteria and rni-
