ABOUT DOCUMENTATION...
The fields used are the following:
ID : Alphanumeric identifier for this stock
SP : Common species name
LATIN : Scientific name for species
Note: there should be a one-to-one relationship between SP
and LATIN.
FAMILY : Family (latin)
CFAMILY : Common family name
Note: there should be a one-to-one relationship between FAMILY
and CFAMILY.
ORDER : Order
STOCK : Stock descriptor
SOURCE : Source of data
COMMENTS : Comments
FAGE : Ages used to compute the Fishing mortality.
METHOD : Method of estimating recruitment and stock (e.g. VPA, RV, cpue).
UNITSSB : Units of spawning stock biomass data
UNITREC : Units of recruitment data
AGERECDAT : Age of recruitment
UNITLAND : Units of landings data
EGGDIAM : Diameter of eggs
LHATCH : Length at hatch
LMETA : Length at metamorphosis
DELTAL : Change in length during larval phase
DELTAN : Change in length during larval phase relative to egg diameter
LATITUDE : Latitude of spawning expressed as two numbers separated by a space.
The first number is degrees (positive means North, negative means
South). The second number is minutes.
LONGITUDE : Longitude of spawning expressed as two numbers separated by a space.
The first number is degrees (positive means East, negative means
West). The second number is minutes.
MONTHSPA : Month spawning
NATMORT : Natural mortality
F01 : Fishing mortality corresponding to the point at which the
marginal yield per recruit from an additional unit of effort
is 0.1 the marginal yield per recruit at very low levels of
fishing (and hence a point beyond which there is little reward
in increasing fishing).
FMAX : Fishing mortality corresponding to maximum yield per recruit.
FMED : Fishing mortality corresponding to median yield per recruit.
KGPRECF0 : "Kilograms per recruit when fishing mortality = 0."
This is something of a misnomer. In fact it is specifies
spawners (in either kg or numbers, depending on whether
the UNITSSB field specifies weight or numbers) per
recruit (generally in numbers but possibly in kg, depending on
whether the UNITREC field specifies numbers or weight).
SPAWNLOC : Spawning location (e.g. shelf, slope, estuary)
SOURCEMAT : Source of maturity data.
LENMAT : Length at maturity (males and females combined).
LENMATM : Length at maturity for males.
LENMATF : Length at maturity for females.
AGEMAT : Age at maturity (males and females combined).
AGEMATM : Age at maturity for males.
AGEMATF : Age at maturity for females.
LENREC : Length at recruitment.
AGEREC : Age at recruitment (males and females combined).
AGERECM : Age at recruitment for males.
AGERECF : Age at recruitment for females.
SOURCEGRO : Source of growth data.
LINFIN : L_infinity parameter in the von Bertalanffy equation
(males & females combined).
k : k parameter in the von Bertalanffy equation
(males & females combined).
to : to parameter in the von Bertalanffy equation
(males & females combined).
LINFINM : L_infinity parameter for males.
kM : k parameter for males.
toM : to parameter for males.
LINFINF : L_infinity parameter for females.
kF : k parameter for females.
toF : to parameter for females.
SOURCEab : Source of a,b data.
aLTWTPAR : a, length wt. parameter (males & females combined).
bLTWTPAR : b, length wt. parameter (males & females combined).
aLTWTPARM : a, length wt. parameter for males.
bLTWTPARM : b, length wt. parameter for males.
aLTWTPARF : a, length wt. parameter for females.
bLTWTPARF : b, length wt. parameter for females.
Each line of the file consists of the name of a field (as above) followed
by a separator character (@) and then the contents of the field.
The fields are always listed in the standard order (as above).
A dot (.) denotes a missing value. Some of the fields listed are not
currently in use.
A Note on Common and Scientific Names:
As noted above, there should be a one-to-one relationship between
SP and LATIN
and also between
FAMILY and CFAMILY.
One reason scientific names exist is that common names often vary
from place to place. We have arbitrarily adopted "standard" common names
which should always correspond exactly (i.e. in a one-to-one way) with
the scientific names.
