Description The thesis presents an account on the physiological response of green
mussel, Perna viridis (Linnaeus) to the temporal and spatial variations in
the environmental parameters of the mussel beds. Condition index, a nonspecific
biomarker which integrates physiological responses of mussels to
multiple stressors is evaluated as the intrinsic response to the variable
environment. The cytological response in the mussels is also elucidated
with reference to the trace metal and organochlorine concentrations of the
shellfish waters. Baseline information on the sanitary quality of the
coastal waters and the extent of faecal contamination of the mussel beds
is also presented.
• The study area covers the mussel beds off Someshwara and Surathkal of
Dakshina Kannada District, Kamataka, where green mussel, P. viridis
contributes to a significant fishery of commercial importance.
• The variations in water temperature, salinity, dissolved oxygen (DO), pH
and the qualitative and quantitative variations in seston of the mussel beds
were studied to evaluate their temporal and site-specific differences
between the two mussel beds.
• With the onset of monsoon a sharp decline in the water temperature,
salinity and pH of the mussel beds was noticed. Bottom water
temperature at Someshwara mussel beds varied between 2S.20°C in
August and 31.1S0C in April. At Surathkal mussel beds, water
temperature ranged between 26. 10°C in August and 31.4SoC in May. The
mean water temperature of the mussel beds varied significantly (p
