Subscripts

Indicating:

$

Economical value of the respective characteristic of the cohort

λ

Maximum age

0.1

Value of F (and of other characteristics of the cohort) corresponding to the air of the biomass equal to 10 percent of the virgin biomass

c

Recruitment to exploitable phase

crash

Value of F which, at long term, corresponds to the collapse value of the spawning biomass

E

Value of the characteristics of the cohort corresponding to an equilibrium point

i

Age

infl

Value of the characteristic corresponding to an inflection point of any relation between that characteristic and other variable.

l

Length

lim

Value of B or of F corresponding to a biological reference limit point

loss

Value of B or of F corresponding to the minimum spawning biomass observed

Max

Value of F (and of other characteristics of the cohort) where the yield per recruit is maximum

Med

Value of F (and of other characteristics of the cohort) which, at long term, will produce a spawning biomass per recruit equal to the median value of the spawning biomasses per recruit observed during a certain period of years

MSY

Value of F (and of other characteristics of the stock) where the long term total yield is maximum

R

Recruitment to the exploitable phase
