Paulraj, R and Kiron, V (1988) Influence of salinity on the growth and feed utilization in Liza parsia fry. In: The First Indian Fisheries Forum Proceedings, 4-8 December; 1987, Mangalore.
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.
