Fishery and biology of the green mussel, Perna viridis (Linnaeus)

Abstract

The green mussel in the natural beds at Kakinada Bay attains an average length of 63 mm in 6 months, 92.2 mm in 1 year and \t 
\n129 mm in 3 years. The mussel stock show a considerable variation from year to year, in spawning activity although it extends \t 
\nfrom December to July with peak activity in January to May. At Kakinada there appears to be no appreciable difference in the \t 
\nbiological cycle of the farm grown mussels and those in natural beds.
