Description Liza parsia is one of the euryhaline species of finfish cultivated in the
low saline coastal waters of India. Since salinity influences growth and
food intake in euryhaline species, an experimental study was carried out
to determine the effect of salinity levels 5%, to 35%, on growth and food
conversion in Liza parsia fry. Salinity levels ranging from 5 to 25%, did not
significantly influence the survival (88.3% to 93%) but 30 to 35%, salinity
levels provided relatively low survival rates of 79.7 and 78% respectivley.
Under the restricted ration (8% of body weight) food intake was not
significantly influenced by salinity. Growth and food conversion rates were
significantly influenced by salinity, levels 15 to 25%, providing the best
growth. This study shows that though L. parsia fry can tolerate salinities
from 5%, to 35%,, levels above 25%, seem to be unfavourable for normal
growth and feed utilization.
