    Abstract

    Age and growth of the little Indian squid Loliolus hardwickei (Gray, 1849) were studied using samples collected in the coastal waters of Arabian Sea. Statolith increment counts demonstrated that L. hardwickei has a fast growth rate (dorsal mantle length: 0.31–0.73 mm day−1 in females and 0.27–0.56 mm day−1 in males) and a short lifespan of less than 6 months. Females are the larger sex and their daily growth rates were higher than in males. The oldest male and female were 110 and 130 days old; the youngest mature female and male were 62 and 52 days old respectively. The oviducal fecundity ranged from 104–480 eggs, mean = 360 eggs (14–23 eggs g−1 body weight).
