Short communication: Morphometric variation and growth rate of Uroteuthis duvaucelii (Cephalopoda: Loliginidae) in the Persian Gulf and Oman Sea using gladius increments
Loliginid squids occur in temperate and tropical coastal waters where they have been considered economically important (Valinassab et al., 2006; Anderson, 2000). Uroteuthis (Photololigo) duvaucelii (Orbigny, 1835) or Indian squid is the most abundant group of Teuthida (Family Loliginidae) in the Persian Gulf and Oman Sea (Valinassab, 1993). These squids demonstrate complex population structures, and are generally characterized by different biological features such as growth rates, size and age of maturity. Over the past 30 years age determination through interpretation of growth increments in the microstructure of the hard structures of squids has accounted for many of the issues and limitations. Naef (1921) was the first to identify growth increments on gladius. The gladius is the internal chitinous shell present in squids, which supports mantle muscles, fins and inner organs. Increments were observed in the middle plate on the dorsal surface of the gladius (Arkhipkin et al., 2012). The series of increments of gladius indicate the amount of daily growth in these species (Perez et al., 2006).
