**Parameters**
*as*_{PHYT}: mussels assimilation
efficiency of phytoplankton [-]
*as*_{DT}: mussels assimilation
efficiency of DT [-]
*a*_{M}: maximum specific mussel growth
rate [day^{-1}]
*k*_{M}: half saturation constant for
mussel filtration [g/m^{3}]
*filt_rate*: average filtration rate
of mussels [m^{3}/sec/g]
*line_no *the number of lines in the
specific mussel farm establishment [-]
*line_length*: the length of the
average cultivation line [m]
*SC1:* mussels of length
<2cm
*SC2:* mussels of length >2cm
*socksSC1*: socks
occupied by mussels of size class 1 [-]
*socksSC2*: socks occupied by
mussels of size class 2 [-]
*musSC1*: dry weight of mussels of size
class 1 [g/m of sock]
*musSC2*: dry weight of mussels of size class 2
[g/m of sock]
*e*_{M}: excretion rate of mussels
[day^{-1}]
*m*_{M}: mortality rate of mussels
[day^{-1}]
*WD*: Wind direction [°] |
*NetGrowth=as*_{PHYT}*{a_{M}*[p_{1}*PHYT/(k_{M}+F)]+as_{DT}*[p_{2}*OD/(k_{M}+F)]}
[6]*Losses= e*_{M}+m_{M}
[7] where *m*_{M}=f(*T*_{w}) as
if
*T*_{w}<25° C then the mortality rate *m*_{M}
=0.02**a*_{M}. if *25° C<T*_{w}<26°
C then the mortality rate is *m*_{M}=0.25* a_{M}.
[8] if *T*_{w}>26° C then the mortality rate is
*m*_{M}=0.5*
