Subject Clam
 
Description Age and growth of A,granosa has been studied by an examination of the size-frequencies of random
samples for the period from April 1965 to September 1966. The cockles measure 31 -5 mm. in length at the
end of the first year and 49.3 mm. at the end of the second year of life. No growth rings were noticed to be
of use in age determination. The commercial catches chiefly consisted of '0' and 1 + age groups in the year
April 1965 to March 1966. The cockles reach sexual maturity when they measure 21 mm. and about 7 months old. They appear to breed throughout the year. There is a peak spawning activity in January- April period. The length-weight relationship has been studied.
