| Abstract: | Investigations on gonado‑somatic index, stages of maturity and fecundity of Parapenaeopsis stylifera were carried out from the Neendakara zone, Kerala coast for a period of one year. Females with mature ovaries occurred throughout the year showing that they spawn continuously the peak season being May and July. The gonado‑somatic index exhibited a variation from 3.39 to 10.54(%). The mean fecundity of 87,641 was observed. There was a linear relationship between the fecundity and the length of shrimp, weight of shrimp, length of ovary and weight of ovary. |
