Life History Data on Leptoclinus maculatus
Daubed shanny
Family: Lumpenidae                           Eel pricklebacks
Max. length (Lmax): cm TL
L infinity (Linf): = cm
K: /year      Ø' =
Median Ø' value with related Linf. and K.

Growth & mortality data
to: years      Estimated from Linf and K.
Natural mortality (M):    s.e. - /year
Estimated from Linf., K and annual mean temp. = °C
Life span (approx.): years    Estimated from Linf., K and to.     Max. age & size data
Generation time: years       Estimated from Lopt, Linf., K and to.
Age at first maturity (tm): years       Estimated from Lm, Linf., K and to.
L maturity (Lm):     s.e. - cm
Estimated from Linf.        Maturity data         
L max. yield (Lopt):     s.e. - cm
Length-weight: cm => (wet weight)  
W = * L ^

Length-weight data
Nitrogen & protein:
Weight (g) => whole-body nitrogen (N) (g)
=> whole-body crude protein (g)
Reproductive guild: guarders: nesters            Reproduction
Fecundity: [ no value (min.)-no value (max.) ]       Estimated as geometric mean.          Fecundity
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).
Main food: mainly animals (troph. 2.8 and up)
Trophic level: 3.3     +/- s.e. 0.39          Estimated from food data.           Food
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 =
