Life History Data on Mogurnda malsmithi
Family: Eleotridae                           Bully sleepers
Max. length (Lmax): = cm
L infinity (Linf): =    s.e. - cm
L maturity (Lm):     s.e. - cm
Estimated from Linf.         
L max. yield (Lopt):    s.e. - cm
Estimated from Linf.
K: /year
Estimate K from Linf, Lm and tm:
Lm =    cm
tm = years
Estimate K from Linf and tmax:
tmax = years
Enter Linf and K:
Linf =    cm
K = /year

 

 
to: years       Estimated from Linf and K.
Natural mortality (M):   s.e. - /year
°C
Life span (approx.):     s.e. -    years      Estimated from Linf., K and to.         
Generation time:     s.e. -    years       Estimated from Lopt, Linf., K and to.
Age at first maturity (tm):     s.e. -    years       Estimated from Lm, Linf., K and to.
Relative Yield per Recruit (Y'/R): Estimate Y'/R from M/K, Lc/Linf and E.
Lc = cm    E =   /year
Emsy /year    Eopt /year
Fmsy /year    Fopt /year
Exploitation: Z=
F=
E= 		Estimate Z, F, E from Lc, Lmean, Linf, K, M
Lc = cm
Lmean = cm
Resilience / productivity:
Vulnerable to extinction if decline in biomass or numbers exceeds threshold over the longer of 10 years or 3 generations.
Intrinsic rate of increase (rm): /year Lr = cm   
Estimated from Fmsy at Lc = length of recruitment (Lr).
Food consumption (Q/B): times the body weight per year Enter Winf, temperature, aspect ratio (A), and food type to estimate Q/B
Winf = g      Temp. = °C
A =
