Annexe 3 LENGTH COMPOSITIONS

(a) CONGO
(b) ANGOLA

(a) CONGO

Data on Sardinella length distributions in Congo from 1964 to 1978, by month, assembled by

P. M'Fina

N = number of fish measured each month

P = monthly landings in tonnes, by the boats of the major industrialized company, where sampling took place

p = total weight of the monthly samples

LF = fork length
