Please define the number of possible age classes allowed in your system, if it is more than one, please enter the average size and standard deviation for size initialization at each age class stage. .

Define the number of possible age classes allowed in your system: Age class

This parameter specifies the age class distribution at initialization. Depending on how many age classes you defined in the Age & Size tab, you can specify the distribution of individuals across those age classes at initialization. The values should sum to 1. For example, if you have 3 age classes and want an even distribution, you would enter 0.33 for each class.

Initializes the sex of the population which can give a ratio of females to males per age class. Up to 4 values may be specified here: e.g., 0.5~0.5~0, for females~males~trojan YY males. The values must equal 1, be separated with a tilda (~), and the number of values provided must be equal to the value given for the sex_chromo variable in the PopVars file. *A special case for Wright Fisher assumption can be specified here by entering ‘WrightFisher’ and only should be used when considering a panmictic population (see CDMetaPOP manual on Special Cases for more details).

Enter the sex ratio at initialization (e.g. 0.5~0.5 for 50% males & 50% females): Sex Ratio

Parameters entered here will be compounded with patch and size level mortalities and should range between 0 and 1 (0 = no mortality, 1 = 100% mortality). Warning! These parameters will interact with patch specific values (PatchVars.csv) See user manual for how class and patch interact.

Apply Mortality Parameters?

No Yes

Define age specific mortality out from natal grounds [0-1] or 'N' for no mortality: Age Mortality Out %

Define standard deviation for age specific mortality out from natal grounds: Age Mortality Out StDev

Define age specific mortality back at natal grounds [0-1] or 'N' for no mortality: Age Mortality Back %

Define standard deviation for age specific mortality back at natal grounds: Age Mortality Back StDev

Define size specific mortality out from natal grounds [0-1] or 'N' for no mortality: Size Mortality Out %

Define standard deviation for size specific mortality out from natal grounds: Size Mortality Out StDev

Define size specific mortality back at natal grounds [0-1] or 'N' for no mortality: Size Mortality Back %

Define standard deviation for size specific mortality back at natal grounds: Size Mortality Back StDev

Parameters entered here will define movement, dispersal, and straying. Warning! These parameters will be multiplied by patch specific values from the PatchVars.csv. See user manual for how class and patch interact.

Apply Movement Parameters?

No Yes

Enter the emigration probability [0-1] applied before moving to rearing/overwinter grounds. Migration Out Prob

Set return probability [0-1] (Set these values to 1 for patch level control on migration) Migration Back Prob

Set straying probability [0-1] of a migrant straying to a patch other than their natal patch Straying Prob

Set dispersal probability [0-1] of an individual undergoing annual dispersal from their natal/spawning patch Dispersal Prob

Define the probability of being a reproductively mature individual and stay this way.

If size option is specified (sizecontrol in RunVars), then these values are not used and population fit parameters based on size/length relationships are used instead. 3 sex class values can be used here, as well, separated by ‘~’.

Do you want to change specific reproduction options?

No Yes

These parameters can be changed manually for each class. The choices offered below will change reproduction options for all classes.

Define litter size or egg number: Fecundity Ind

Define litter size or egg number standard deviation: Fecundity Ind StDev

Define fecundity values specific to the Leslie matrix model: Fecundity Leslie

Define standard deviation fecundity values specific to the Leslie matrix model: Fecundity Leslie StDev

Parameters entered here will define capture probabilities for individuals based on their location (in natal grounds vs out from natal grounds).

Do you want to apply class specific capture probabilities?

No Yes

Define the capture probability when individuals are out from natal grounds [0-1]: Capture Out Probability

Define the capture probability when individuals are back at natal grounds [0-1]: Capture Back Probability
